The present invention relates to polyolefin compositions that can be used as insulation for wires and cables and which give this isolation increased resistance to the adverse effects of heat, oxygen and moisture. These stabilized compositions can be used in the telecommunications cables (Telecom cables).

Typical telecommunication cable ties are made of twisted pairs of copper cables with polyolefin insulation, which together form a bundle of wires, the sheathed cable. This cable sheath consists of a metal foil and/or armor cable in combination with a polymeric protective material. The entire system is called the "Telecom cables".

To reduce the risk of water penetration into the cable system and to minimize the adverse effects of moisture on polyolefin insulation this system make watertight by filling the voids of the cable hydrophobic lubricant. Cable systems of this type are described, for example, in U.S. patent No. 3888709, 4044200, 4218577, 5502288, in European patent application 565868 A2 and in the works cited in the present description. It is known that the filler cables in the form of fat grease extract stabilizers included in the wire insulation. It was discussed, for example, in "Plastics Additives Hndbook", 3rdEdition, R.Gachter, H.Muller, Eds., Hanser Publishers, pages 116-119 (1990)].

It is often necessary connection between two or more telecommunication cables and the connection is carried out in an external box, known as ground box or junction box. Inside the basement of the box remove the cable sheath, wipe the grease filler cable and connect the transmission wire, if necessary. Thus, the insulated wires are in open space, exposed to the adverse effects of heat, oxygen and moisture. Polyolefin insulation, lost part of its stabilizing additives in the extraction of fatty filler, especially affected by these external conditions and can detect premature oxidative degradation. This degradation manifests itself in the loss of the physical properties of the insulation, which, ultimately, leads to distortion of the transmission parameters of an electrical signal.

Stabilization of polyolefin wire insulation in telecommunication cables using difficult phenolic antioxidants is well known. The modern system of stabilizers includes the use of sterically constrained phenol together with desactivation metals, such as Irganox®MD 1024, 1,2-bis(3,5-di-tert-butyl-4-hydroxyI roconnor)hydrazine or Naugard® XL-1, 2,2'-oxalylamino-bis[ethyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]. A typical set of stabilizers includes as a primary antioxidant Irganox®1010 pentaerythritoltetranitrate-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], and as deactivator metals Irganox®MD 1024. This system is described in European patent application 565868 A2 and in U.S. patent No. 4044200, 5380591 and 5575952.

It is assumed that the present invention can be used for various systems in which moisture is present, including the coating of wires and cables. While not mentioned cable systems with fat coating, where there is a possibility of extraction of the present additives.

In U.S. patent No. 5380591, 5453322, 5575952, 5766761 and 5807635 described stabilization of telephone cables, filled with the hydrocarbon lubricant, in combination with a mixture of alkylhydroxylamines and functionalized sterically constrained Amin. In each work as hydrazine is described, in particular, Irganox® MD 1024.

In U.S. patent No. 5474847 described the stabilization of polyolefin wire insulation in filled fat grease telephone cables in combination with reaction products of hydrazine powered derivatives of sterically obstructed phenols or sterically obstructed amines or amino derivatives of sterically obstructed amines with quinone.

The Pat is the U.S. No. 5502288 described the stabilization of polyolefin insulation of wires in a telephone cable using Irganox® MD 1024 or Naugard® XL-1 or their mixtures with selected antioxidants.

In WO 93/24938 described design filled with fatty greasing the cable, in which polyolefin insulation covering the wire, includes the anhydride of the aliphatic dibasic acid, one or more functionalized sterically obstructed amines and/or functionalized sterically obstructed phenols.

To protect polyolefin wire insulation exposed to the environment in connecting orobko, and to prevent extraction of stabilizers grease-filled cable has been proposed to use high levels of system load stabilizers. It is necessary to search for more effective combinations of primary antioxidant/deactivator metal"than those already used by specialists in order to reduce the significant costs associated with these levels of stabilizers. In this context, "efficiency stabilization" means the total capacity of the system stabilizers to prevent their extraction from polyolefin wire insulation in adipose filler cable and report specified polyolefin resistance to the adverse effects of heat, oxygen and moisture.

It has been unexpectedly discovered that the combination of one or more primary phenolic antioxidants selected from the Irganox® 1098, N,N'-hexane-1,6-diylbis-(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionic)), Irganox® 3114, Tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate and Irganox® 3125, Tris(2-(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)ethyl)isocyanurate, together with one or more alkylhydroxylamines decontamination officers of metal is particularly effective for messages oxidation stability of polyolefin wire insulation in the body filler telecommunications which include cables.

The polyolefin component (a) are mostly thermoplastic resin, which are structured. They can be homopolymers or copolymers formed from two or more comonomers, or a mixture of two or more of these polymers usually used is been created in the films, the plates and tubes, and also used as a protective and/or insulating materials in wire and cable applications. The monomers used in the production of these homopolymers and copolymers can have 2-20 carbon atoms, preferably 2-12 carbon atoms. Examples of these monomers are alpha-olefins such as ethylene, propylene, 1-butene, 1-hexene, 4-methyl-1-penten and 1-octene, unsaturated esters such as vinyl acetate, acrylate, methyl acrylate, methyl methacrylate, tert-butyl acrylate, n-butyl acrylate, n-butylmethacrylate, 2-ethyl hexyl acrylate and other alkylacrylate; diolefin, such as 1,4-pentadiene, 1,3-hexadiene, 1,5-hexadiene, 1,4-octadiene, ethylidenenorbornene, usually the third monomer in terpolymer; other monomers such as styrene, p-methylsterol, alpha-methyl styrene, p-chloresterol, vinylnaphthalene and similar ailelerini, NITRILES, such as Acrylonitrile, Methacrylonitrile and alpha chloroacrylonitrile, vinylmation, vinylmations ether, vinylidenechloride, maleic anhydride, vinyl chloride, vinylidenechloride, vinyl alcohol, tetrafluoroethylene and chlorotrifluoroethylene; and acrylic acid, methacrylic acid, and other similar unsaturated acids.

Polyolefins, i.e. the polymers of monoolefins, examples of which are presented above, and preferably polyethylene and polypropylene, can be obtained, and in particular, by the following methods:

a) radical polymerization (normally under high pressure and at elevated temperature);

b) catalytic polymerisation using a catalyst that normally contains one or more metals of groups IVb, Vb, VIb or VIII of the Periodic table of elements. These metals usually have one or more ligands, mainly oxides, halides, alcoholate, esters, ethers, amines, alkali, alkenyl and/or arily, which can be πor σ-coordinated. These metal complexes may be present in free form or they may be fixed on substrates, typically on activated magnesium chloride, titanium chloride(III), aluminium oxide or silicon dioxide. These catalysts can be soluble or insoluble in the medium for polymerization. When these polymerization catalysts may be used in pure form or they can be used as an additional activators, usually in the form of metallkile, metal hydrides, alkylhalogenide metals, Ala is lexidog metals or alkylamino metals, moreover, these metals are the elements of groups Ia, IIA and/or IIIa of the Periodic table of elements. These activators can be appropriately modified in other ester, ether, aminovymi or silylamine groups. These catalysts are usually referred to as Phillips catalysts, catalysts Standard Oil Indiana, catalysts, Ziegler (-Natta)catalysts TNZ (DuPont), metallocene catalysts or single-catalysts (YAKO).

The homopolymers or copolymers can be structured or solidified using organic peroxides or to give them gidroliznaya properties, they can be grafted with alkenylsilanes in the presence of an organic peroxide, which acts as a generator or catalyst free radicals. Suitable alkenylsilanes are vinyltriethoxysilane, such as VINYLTRIMETHOXYSILANE, vinyltriethoxysilane and VINYLTRIMETHOXYSILANE. These alkeneamine and alkoxyalkyl can have 1-30 carbon atoms, preferably 1-12 carbon atoms. These hydrolyzable polymers can be solidified in moisture conditions in the presence of a catalyst silanolate condensation, such as dilaurate dibutylamine, maleate dactylology, acetate, tin(2), octoate tin(2), lead naphthenate, octoate zinc, 2-atilgan the oat iron and other carboxylates of metals.

Hydrocarbon oil-filled cable component (ii) is a mixture of hydrocarbon with the joining, which is semi-solid at temperatures used. In industry it is known as "filler cable". Typical requirements fillers cable lies in the fact that this fat grease had minimum leakage from the cut end of the cable at 60°With or at higher temperatures. Another typical requirement is that this fat grease prevented the penetration of water on a narrow piece cut off the cable when the pressure of water supplied from one end. Other typical requirements are economic competitiveness; minimum negative impact on signal transmission; minimum negative impact on the physical characteristics of polymeric insulating materials and materials for membranes cable; thermal stability and oxidation resistance and manufacturability cable.

Manufacturer of cable can be carried out by heating the filler wire to a temperature of approximately 100°S. This leads to the dilution of the filler so that it can be fed by the pump into the core stranded cable for full filling the intermediate spaces and the removal of airspace. Alternatively, thixotropic fillers cable using induced by the shear flow can be treated with gennych temperatures in the same way. Cross-section of the conductive core made of cable, fat filled filler, consists of approximately 52 percent of insulated wire and approximately 48 percent of the intermediate spaces throughout the cross-sectional area. Since these intermediate spaces are completely filled with the filler of the cable core is filled cable typically contains about 48 percent (by volume) of filler cable.

Filler cable to either one or more of its hydrocarbon components seen as isolated by removal of the intermediate spaces. Usually in isolation absorbed from about 3 to 30 wt.% filler cable or one or more hydrocarbon components throughout the mass of the polyolefin insulation. Typical absorption is in the range from about 5 to about 25% by weight of the polyolefin. Filler cable typically contains hydrocarbons with different molecular weights. Absorption or swelling filler cable polyolefin insulation mainly happen when more low molecular weight components of the filler cable. This swelling polyolefin insulation leads to migration of additives from isolation in the filler cable, as described above. Therefore, the presence of filler cable creates additional obstacles for the stabilization is of polyolefin insulation.

Examples of hydrocarbon fatty filler wire (filler cable) are petrolatum; a mixture of vaseline/polyolefin wax; oil-filled thermoplastic rubber (ETPK or filled thermoplastic rubber); paraffin oil; naphthenic oil; mineral oil; the above oils, thickened residual grease, petroleum butter or wax; polyethylene wax; a mixture of mineral oil/rubber block copolymers"; grease and their various mixtures that meet industrial requirements listed above.

Besides preventing extraction of antioxidants, stabilized polyolefin composition wire insulation must be resistant to any destabilizing action of the components absorbed from the filler cable. In addition, the stabilizing composition should isolate conductive copper wire, which is a potential catalyst for the oxidative degradation of polyolefin, and it should also prevent the action of chemical residues of pore present in the porous and porous/solid (foam/film) polymeric foam insulation.

In addition to the components (b) and (C), the insulation of the cable design of the present invention may contain additional costabilizer (additives)such as, for example, the following connection is the link:

Example 1: Stabilization of polyolefins in cable construction with fatty filler to 100 parts of high density polyethylene were mixed in dry form with 0.4 parts of Irganox® MD 1024 (1,2-bis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)of hydrazine) and 0.2 cha the authorities of one of the primary antioxidants, listed below in table 1. This mixture was subjected to granulation by forming in the melt at 230°in the extruder Superior/MPM using the auger with respect to the length/diameter (L/D) of 24:1 and head Maddock, while mixing at a speed of 60 Rev/min

Granular polyethylene containing a stabilizing mixture was subjected to direct pressing in solution at 204°With (400° (F) to obtain the film thickness of 0,254 mm (0.01 inch) with false Mylar. These test films was measured initial time induce oxidation" (initial SIV).

Then the samples of the films were immersed in the gel Witcogel®, supplied by Witco, a typical hydrocarbon grease filler cable used in telephone cables. Filler Witco contains 0.6% of Irganox® 1035, thiodiethanol[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]. Samples of films buried in the filler, was kept in an air dryer at 70°C for 14 days. Then the samples were cleaned to remove fat filler cable. Then these samples were determined by the time of induction of oxidative aging" (VIOS).

Test for SIV was performed using differential scanning calorimeter standard test method for ASTM No. D3895. The tests were carried out under the following conditions: not aluminum Chan; no screen; heated to 200°C in nitrogen atmosphere with sleduyushim switching to oxygen at a rate of 100 milliliters per minute. Time induce oxidation (SIV) is a time interval between the start of flow of oxygen and exothermic decomposition of the test specimen. MHA expressed in minutes: more than SIV, the more effective is a mixture of stabilizers in preventing oxidative degradation. The relative effectiveness of mixtures of stabilizers in their application in the filler cable can be predicted by comparing the values of the initial MHA and values VIOS.
