Description
Technical field
The present invention relates to track traffic electric wire cables manufacturing technical field, particularly a kind of prescription of oil-resisting type cross linked insulation material of low-smoke halogen-free inflaming-retarding cable.
Background technology
As everyone knows, the demand of fireproofing cable material without halide quantitatively had growth by a relatively large margin in recent years, had higher requirement on the kind.Fireproofing cable material without halide can be divided into thermoplastics type and cross-linking type.Thermoplastics type's electric cable material with low smoke and halogen free is mainly used in the sheath material of all kinds of cables such as power cable, umbilical cable, communication cable.The crosslinking type low-smoke halogen-free flame-retardant CABLE MATERIALS is used for the insulation that electric wire is used with insulation and sheath, automobile electric wire and the appliance equipment of cable, the industrial cable of nuclear power, used for rolling stock cable in the naval vessel more.
Main at present employing polyolefin substrate of fireproofing cable material without halide and inorganic fire-retarded filler are the compound system of main component.Inorganic fire-retarded filler mainly is aluminium hydroxide or magnesium hydroxide, when matrix material is heated to certain temperature, the release water outlet will take place to decompose in aluminium hydroxide or magnesium hydroxide, thereby the concentration of cooling and minimizing oxygen reaches fire-retardant effect, this system discharges gas when burning main component is carbonic acid gas and water, thereby smoke density is very low, and corrodibility and toxicity are also little.But because the flame-retarded efficiency of aluminium hydroxide or magnesium hydroxide is low, make it reach fire-retardant purpose, must in base-material, add a large amount of aluminium hydroxide or magnesium hydroxide, need to reach 70% sometimes.This will unavoidably cause declining to a great extent of Material Physics mechanical property, electric property and process industrial art performance.For the every performance index that make material reach suitable balance, often select higher mechanical strength and polyethylene or the EVA base material good for use with the inorganic combustion inhibitor consistency, satisfy the mechanical property requirement of material.
For polyethylene or EVA base material, because its nonpolar molecular structure, its oil resistance is relatively poor usually, causes the oil resistance of halogen-free low-smoke flame retardant material relatively poor.Some occasion, for example: the used for rolling stock cable needs oil resistance preferably.For this reason, the performance of grease-proof low-smoke halogen-free flame-retardant insulating material is very crucial.
Summary of the invention
At the oil resistance deficiency that existing low-smoke halogen-free flame-proof cable material exists, the object of the present invention is to provide a kind of environment-friendly cable insulating material of cross-linking type oil resistant low-smoke non-halogen flame-retardant.

Above-mentioned component is mixing by a certain percentage, mixing main technique flow process: material stirs companion, Banbury mixer banburying, double-screw extruding pelletizing, through being extruded on the conductor with forcing machine after the granulation, and it is crosslinked to carry out electron radiation again, makes electric wire.
Wherein said ethene-vinyl acetate multipolymer is that the interpolymerization by ethene and vinyl acetate forms, and the MU (methylene unit) that forms saturated main chain by the side acetoxy group is formed in theory, and wherein, the content of vinyl acetate is 25%-80%.
Described paracril is that vinyl cyanide and butadiene copolymer close and form, and wherein, the content of vinyl cyanide is controlled between 28%～40%.
Described oxidation inhibitor is selected phenolic antioxidant, amine antioxidants and phosphorous acid lipid for use.The effect of oxidation inhibitor is the oxidizing reaction that suppresses or delay polymkeric substance, eliminate and generate peroxidation radical, reduction alkoxyl group or alkyl radical, and decompose hydroperoxide in the oxidizing reaction, thereby oxidative chain reactions is stopped, reach the purpose that prevents the polymkeric substance oxygen aging.
Described sensitizing agent is selected multi-functional esters of acrylic acid for use, as trimethylammonium vinylformic acid trishydroxymethyl propyl ester (TMPTMA), cyanacrylate (TAIC), triallylcyanurate, crosslinking sensitizer can reduce the crosslinked required absorption dose of material irradiation, and reduces electric, physicals negative impact to material.
Described tinting material is selected carbon black or silicon-dioxide for use.
Described processing aid comprises lubricant, lubricant select for use have long aliphatic alkyl such as stearic acid, paraffin and or material such as siloxanes.
The present invention has selected the compound of proper polymer base-material ethene-vinyl acetate multipolymer and paracril, and by inorganic powder surface being handled the oil resistance that improves material, makes the low-smoke halogen-free flame-proof cable material with better oil resistance.
