Thiscoating comprises (a) a crystalline propylene homopolymer or copolymer; (b) a copolymer ofethylene with at least one alpha-olefin having from 3 to 12 carbon atoms, and optionally with adiene, said copolymer (b) being characterized by a composition distribution index, defined as theweight percentage of copolymer molecules having an alpha-olefin content within 50 % of theaverage total molar content of alpha-olefin, greater than 45 %; (c) natural magnesium hydroxide.

Title: Low-smoke self-extinguishing cable and flame-retardant composition used therein Title - DWPI: Flame retardant coating composition for making cables self extinguishing useful forlow voltage electrical energy distribution and telecommunication cables with superior mechanicalproperties Publication Number: KR552083B1 Priority Date: 2000-01-22 First Claim: From corresponding WO1999005688A1 magnesium hydroxide thus obtained is claimed to be useful as a flame-retardant for polyolefin resins. In particular, the examples describe compositions withflame-retardant properties based on ethylene/vinyl acetate (EVA) and ethylene/ethyl acrylate(EEA) copolymers. Japanese patent application JP-03-231,944 (Kokai) describes polyolefin-basedcompositions having flameretardant properties and containing magnesium hydroxide with anaverage particle diameter of between 3 and 13 pm and the following particle size distribution: 1-20% by weight of particles with a diameter less than or equal to 1 pm; 55-98% by weight ofparticles with a diameter between 1 and 15 pm; 1-25% by weight of particles with a diameter

45

between 15 and 50 pm. This particle size distribution is believed to afford higher flame resistance,which would be accompanied by good mechanical strength, flexibility and processability. Amagnesium hydroxide with these properties would be obtainable by suitable grinding of naturalbrucite, followed by sieving or addition of another material of predetermined particle size.According to the description given in the abovementioned patent application, this type ofmagnesium hydroxide would be useful as a flame-retardant filler for polyolefins such aspolyethylene, olefinic rubbers, polypropylene, polybutene and the like. Particular mention is madeof ultra-low-density polyethylene (ULDPE) having a density of 0.860-0.910 g/cm 3, obtainable bycopolymerization of ethylene with an alpha-olefin in the presence of a conventional Ziegler-Nattacatalyst based on titanium and/or vanadium compounds. Lastly, Japanese patent application JP-05-17692 (Kokai) describes polymer compositions havingflameretardant properties and containing natural magnesium hydroxide which has previously beenground and surface treated with a fatty acid or a fatty acid salt, or alternatively with a silane or atitanate acting as coupling agent. These compositions would be characterized by high resistanceto acid attacks. The subsequent Japanese patent application JP-07-161230 (Kokai) describescompositions similar to the above, pointing out that, in order to decrease the hygroscopicity ofmagnesium hydroxide, the latter must be surface-treated with the same products as mentionedabove, in amounts of between 0.5 and 5% by weight relative to the magnesium hydroxide weight.In both of the above-mentioned Japanese patent applications, polyolefins such as polyethylene,ethylene /propylene rubbers, acrylic rubbers and the like are cited as polymeric materials, andflame-retardant compositions based on ethylene/ethylacrylate (EAA) polymers are given asparticular examples. No information is provided regarding mechanical, elastic or processabilityproperties of the resulting mixtures. From the foregoing, it is clear that in the prior art considerable efforts have been made to improvethe properties of flame-retardant polymer compositions containing magnesium hydroxide bymodifying the properties of magnesium hydroxide itself, in terms of crystallinity, particle sizedistribution and/or surface properties. These modifications have been achieved either bydeveloping synthetic processes starting from soluble magnesium salts or by appropriatelymodifying and treating natural magnesium hydroxide. For the purposes of the present invention,with enhanced flame-retardant properties it is meant that a cable passes a test as defined bystandard CEI 332-1; with enhanced mechanical properties it is meant a high elongaticn at breakvalue and a relatively low modulus, which are capable of determining a cable flexibility which issuitable for use; in particular, it is meant that mechanical properties are essentially not lower thanthose of cables using compositions of known type, for example halogenated compositions. TheApplicant has now found that it is possible to produce self-extinguishing, halogen-free cablesproducing a low level of fumes and having high flame resistance and excellent mechanicalperformances by using natural magnesium hydroxide as flame-retardant filler and, as polymermatrix, a polymeric mixture comprising a crystalline propylene homopolymer or copolymer and acopolymer of ethylene with an alpha-olefin, and optionally with a diene, characterized by uniformdistribution of the alpha-olefin among the copolymer molecules. Therefore, according to a firstaspect, the present invention relates to a cable with self-extinguishing properties, comprising aconductor and a flame-retardant coating, characterized in that the said flame-retardant coatingcomprises: (a) a crystalline propylene homopolymer or copolymer; (b) a copolymer of ethylenewith at least one alphaolef in, and optionally with a diene, said copolymer (b) being characterizedby a composition distribution index greater than 45%, said index being defined as the weightpercentage of copolymer molecules having an alpha-olefin content within 50% of the average total

46

molar content of alpha-olefin; (c) natural magnesium hydroxide in an amount such as to impartflame-retardant properties. In a second aspect, the present invention relates to a flame-retardant composition comprising: (a)a crystalline propylene homopolymer or copolymer; (b) a copolymer of ethylene with at least onealphaolefin, and optionally with a diene, said copolymer (b) being characterized by a compositiondistribution index greater than 45%, said index being defined as the weight percentage ofcopolymer molecules having an alpha-olefin content within 50% of the average total molar contentof alpha-olefin; (c) natural magnesium hydroxide in an amount such as to impart flame-retardantproperties. The composition distribution index provides an indication of the distribution of the alpha-olefinamong the copolymer molecules (the higher the value of this index, the more homogeneous thedistribution of the comonomer among the copolymer molecules), and can be determined byTemperature Rising Elution Fractionation, as described, for example, in patent US-5,008,204 or inWild et al. , J. Poly. Sci. Poly. Phys. Ed., Vol. 20, p. 441 (1982). Tn the Applicant's the composition view, distribution index is related to the ability of thecopolymers of ethylene with an alpha-olefin, and optionally with a diene, to incorporate anddisperse large amounts of the flame-retardant filler, thereby obtaining a mixture having excellentflame-resistance and, at the same time, good processability and improved mechanical properties.Given a certain ratio between flame-retardant filler and polymer matrix, it is important to determinethe minimum value of this index which is sufficient to obtain the desired combination of mechanicalproperties and processability. Moreover, the presence in the polymer mixture of a crystalline propylene homopolymer orcopolymer makes it possible to obtain a thermoplastic coating which has increasedthermocompression resistance even at the maximum operating temperatures, so as to pass thethermocompression test described in CEI standard 20-34/31. This test consists in subjecting the coating of a cable specimen to a predetermined compression ata predetermined temperature and for a predetermined time. At the end of the test, the flattening degree of the coating, expressed as percentage of the residualthickness relative to the initial thickness of the coating, is measured: the sample passes the test ifits residual thickness is greater than 50% of its initial thickness. In a further aspect, the presentinvention relates to a method for obtaining a cable having improved mechanical properties andincreased fire resistance, said method comprising the following steps: (1) preparing a polymermixture having flameretardant properties; (2) extruding said mixture on a conductor optionallyprecoated with an insulating layer, characterized in that step (1) comprises mixing apredetermined amount of natural magnesium hydroxide with a polymer mixture comprising: (a) acrystalline propylene homopolymer or copolymer, as a polymeric component capable of increasingthe thermocompression resistance of the flame-retardant coating; and: (b) a copolymer of ethylenewith at least one alphaolefin, and optionally with a diene, capable of dispersing natural magnesiumhydroxide, so as to improve processability of the mixture and enhance mechanical properties ofthe flame-retardant coating. The amount of natural magnesium hydroxide to be added is predetermined so as to obtain a cable

47

which is capable of passing the fire-resistance test according to CEI standard 332-1. The amountof propylene homopolymer or copolymer (a) is such that the flame-retardant coating obtained afterextrusion has a value of thermocompression resistance, measured at 1000C according to CEIstandard 20-34/3-1, greater than 50%. The amount of copolymer (b) is such that the flame-retardant coating obtained after extrusion has an elongation at break, measured according to CEIstandard 20-34 5.1, of at least 100%, preferably of at least 150%, and a modulus at 20%,measured according to CEI standard 20-34 5.1, of less than 12 MPa, preferably less than 7 MPa. Figure 1 shows, in a schematic form, the crosssection of a low-voltage electrical cable of unipolartype according to one embodiment of the present invention, this cable comprising a conductor (1),an inner layer (2) acting as electrical insulation and an outer layer (3) acting as a protective sheathwith flameretardant properties, consisting of the composition according to the present invention. The term "low voltage" is understood generally to refer to a voltage of less than 2 kV, preferablyless than 1 kV. The inner layer (2) may consist of a haiogen-free, crosslinked or non-crosslinked polymercomposition with electrically insulating properties which is known in the art, selected, e.g., from:polyolefins (homopolymers or copolymers of different olefins), olefin/ethylenically unsaturatedester copolymers, polyesters, polyethers, polyether/polyester copolymers, and mixtures thereof. Examples of such polymers are: polyethylene (PE), in particular linear low density PE (LLDPE);polypropylene (PP) ; propylene/ethylene thermopl:astic copolymers; ethylene/propylene rubbers(EPR) or ethylene /propylene/diene rubbers(EPDM) ; natural rubbers; butyl rubbers;ethylene/vinylacetate (EVA) copolymers; ethylene/methylacrylate (EMA) copolymers;ethylene/ethylacrylate (EEA) copolymers; ethylene /butylacrylate (EBA) copolymers; ethylene/alphaolefin copolymers, and the like. It is also possible to use the same polymer base for the innerlayer (2) as well as for the outer layer (3), namely the mixture of (a) and (b) as defined above. Alternatively, a self-extinguishing cable according to the present invention may consist of aconductor coated directly with the flame-retardant composition described above, withoutinterposing other insulating layers. In this way, the flame-retardant coating also acts as electricalinsulator. A thin polymer layer acting as an anti-abrasive can then be externally added, optionallysupplemented with a suitable pigment to colour the cable for identification purposes. According to the present invention, with the term natural magnesium hydroxide it is meantmagnesium hydroxide obtained by grinding minerals based on magnesium hydroxide, such asbrucite and the like. Brucite is found in its pure form or,, more often, in combination with other minerals such as calcite,aragonite, talc or magnesite, often in stratified form between silicate deposits, for instance inserpentine asbestos, in chlorite or in schists. For the purposes of the present invention, brucite can be ground according to known techniques,under wet or dry conditions, preferably in the presence of grinding coadjuvants, for examplepolyglycols or the like. The specific surface of the ground product is generally between 5 and 20M2/g, preferably between 6 and 1,5 M2/g.

48

The magnesium hydroxide thus obtained can then be classified, for example by sieving, to obtainan average particle diameter generally of between 1 and 15 pm, preferably between 1.5 and 5 pm,and a particle size distribution such that not more than 10% of the total number of particles have adiameter lower than 1.5 pm, and not more than 10% of the total number of particles have adiameter greater than 20 pm. Natural magnesium hydroxide generally contains various impurities derived from salts, oxidesand/or hydroxides of other metals such as Fe, Mn, Ca, Si, V, etc. Amount and nature of theimpurities can vary depending on the source of the starting mineral. The degree of purity isgenerally between 80 and 98% by weight. As regards water-soluble ionic-type impurities, theircontent can be determined indirectly by measuring electrical conductivity of an aqueous extractobtained by placing magnesium hydroxide in contact with a suitable amount of water for apredetermined period of time at a predetermined temperature. A more detailed description of thismeasurement, based on ISO method 787, is given hereinbelow. According to this method,electrical conductivity of the aqueous extract obtained from natural magnesium hydroxide isgenerally between 100 and 500 pS/cm, preferably between 120 and 350 pS/cm. The natural magnesium hydroxide according to the present invention can be used as such or inthe form of particles whose surface has been treated with saturated or unsaturated fatty acidscontaining from 8 to 24 carbon atoms, or metal salts thereof, such as, for example: oleic acid,palmitic acid, stearic acid, isostearic acid, lauric acid; magnesium or zinc stearate or oleate; andthe like. To increase compatibility with the polymer matrix, natural magnesium hydroxide can alsobe surfacetreated with suitable coupling agents, for example organic silanes or titanates such asvinyltriethoxysilane, vinyltriacetylsilane, tetraisopropyititanate, tetra-n-butyltitanate, and the like. Using Scanning Electron Microscopy (SEM), it has been observed that natural magnesiumhydroxide has a highly irregular granular morphology in terms both of its geometrical shape and ofits surface appearance. In contrast, the magnesium hydroxide obtained by precipitation consists offlattened hexagonal crystallites that are substantially uniform both in size and morphology. As regards the copolymers (b), they are generally characterized by a narrow molecular weightdistribution, with an index of molecular weight distribution (MWD) , defined as the ratio betweenthe weight-average molecular weight Mw and the number-average molecular weight Mn, Of lessthan 5, preferably between 1.5 and 3.5. The molecular weight distribution index can bedetermined, according to conventional methods, by Gel Permeation Chromatography (GPC). With alpha-olefin it is meant an olefin of formula CH2=CH-R, wherein R is a linear or branchedalkyl having from 1 to 10 carbon atoms. The alphaolefin can be selected, for example, frompropylene, 1-butene, 1 pentene, 4-methyl-l-pentene, 1-hexene, 1-octene, 1_ dodecene and thelike. Propylene, 1-hexene and 1-octene are particularly preferred. When the alpha-olefin is propylene, the copolymers (b) are also characterized by highregioregularity in the sequence of monomer units. In particular, these copolymers have a numberof-CH2-groups in-(CH2)n_ sequences, where n is an even integer, relative to the total number of-CH2-groups, generally lower than 5% by mole, preferably lower than 1% by mole. This quantitycan be determined according to known techniques by means of 3C-NMR analysis. When a diene comonomer is present, it generally has from 4 to 20 carbon atoms, and is preferably

49

selected from: linear, conjugated or non-conjugated diolefins, for example 1,3-butadiene, 1,4-hexadiene or 1,6-octadiene; monocyclic or polycyclic dienes, for example 1,4cyclohexadiene,-ethyl idene-2-norbornene, 5-methylene-2norbornene, and the like. In general, for the purposes of the present invention, the desired mechanical andthermocompression resistance characteristics of the flame-retardant coating may be obtainedusing polymer mixtures comprising from 5 to 60% by weight, preferably from 10 to 40% by weight,of a crystalline propylene homopolymer or copolymer (a), and from 40 to 95% by weight,preferably from 60 and 90% by weight, of a copolymer (b), the percentages being referred to thetotal weight of the polymeric components (a) and (b) . Within the class of copolymers (b) as defined above, two main groups of products can bedistinguished. The first group (bl) consists of copolymers of ethylene with at least one C3-C12 alpha-olefin, andoptionally a diene, these copolymers having elastomeric properties and preferably characterizedby:-melting enthalpy lower than 35 J/g, preferably lower than 30 J/g;-intrinsic viscosity [ill generallygreater than 1.0 dl/g, preferably greater than 2. 0 dl/g (determined in tetralin at 135'C);-Mooneyviscosity ML(1+4) at 125"C (measured according to Standard ASTM D1646) generally greaterthan 10, preferably of from 20 to 90;-solubility in pentane at 2CC generally greater than 80% byweight;-tension set at 200% (measured at 2CC for 1 minute according to ASTM standard D 412)lower than 30%. Tension set provides a measure of the elastic recovery properties of the non-crosslinked material.This is determined by subjecting a sample of the tested material to a tensile force such as toobtain an elongation of 200% for a predetermined period. After removing the stress, thepermanent deformation of the sample, which is expressed as a percentage relative to its initialdimensions, is measured: the smaller this value, the better the elastic properties of the material. The copolymers belonging togroup (bl) generally have the followingcomposition: 35-90% by moleof ethylene; 10-65% by mole of alpha-olefin, preferably propylene; 0-10% by mole of a diene,preferably 1,4 hexadiene or 5-ethylidene-2-norbornene. When the alpha olefin is propylene, themonomer composition is preferably as follows: 55-80% by weight, preferably 65 75% by weight, ofethylene; 20-45% by weight, preferably 25-35% by weight, of propylene; 0-10% by weight,preferably 0-5% by weight, of a diene (preferably 5 ethylene-2-norbornene). When the alpha-olefinis propylene, the propylene units are in the form of triads generally in amounts of between 4 and50% by mole with respect to the total amount of propylene, and at least 70% of these triads haveisotactic structure, as shown by 13 C-NMR analysis. The second group (b2) consists of copolymers of ethylene with at least one C4-CI2 alpha-olefin,preferably 1-octene, and optionally a diene, preferably characterized by:-a density of between 0.86and 0.90 g/cm 3-a melting enthalpy of between 30 and 60 i/g;-Melt Flow Index (MFI), measuredaccording to ASTM standard D 1238/L, of between 0.1 and 30 g/10 min, preferably between 0.5and 5 g/10 min. The copolymers belonging to group (b2) generally have the following composition:75-97% by mole, preferably 90-95% by mole, of ethylene; 3-25% by mole, preferably 5-10% bymole, of alpha-olefin; 0-5% by mole, preferably 0-2% by mole, of a diene. The copolymers (b) can be obtained by copolymerization of ethylene with an alpha-olefin, and

50

optionally with a diene, in the presence of a "singlesite" catalyst, for example a metallocenecatalyst, as described, e.g., in patent applications WO 93/19107 and EP-A-632,065 (for thecopolymers of group (bl)) or in patents US-5,246,783 and US-5,272,236 (for the copolymers ofgroup (b2) ) .

Organometallic Chemistry, 479 (1994), 1-29, or patentsUS-5,272,236, US5,414,040 and US-5,229,478, or the above-mentioned patent applications WO93/19107 and EP-A-632065, and patents US5, 246, 783 and US-5, 272, 236) . Catalysts whichare suitable for obtaining the copolymers (b) according to the present invention are also thesocalled "Constrained Geometry Catalysts" described, for example, in patents EP-416,815 andEP-418,044. The crystalline propylene homopolymers or copolymers (a) generally have a melting enthalpygreater than 75 J/g, preferably greater than 85 J/g. They may be selected in particular from: (1)isotactic propylene homopolymers with an isotacticity index greater than 80, preferably greaterthan 90, even more preferably greater than 95; (2) propylene homopolymers obtainable by usingmetallocene catalysts, having a pentad irmimm content greater than 90% (determined by 13C-NMR analysis); (3) crystalline copolymers of propylene with ethylene and/or an alpha-olefin havingfrom 4 to 10 carbon atoms, with an overall content of ethylene and/or alpha-olefin lower than 10%by mole; (4) heterophasic propylene copolymers obtainable by polymerization in sequence ofpropylene and of mixtures of propylene with ethylene and/or an alpha-olefin having from 4 to 10carbon atoms, containing at least 70% by weight of polypropylene homopolymer or of crystallinepropylene /ethylene copolymer, with an isotacticity index greater than 80, the remainder consistingof an elastomeric ethylene /propylene copolymer with a propylene content of between 30 and 70%by weight; (5) crystalline propylene homopolymers or copolymers having syndiotactic structureobtainable by using metallocene catalysts.
