Description
Technical field
The invention belongs to CABLE MATERIALS technical field, be specifically related to the ageing-resistant CABLE MATERIALS of a kind of cable low-smoke non-halogen flame-retardant.
Background technology
Electric wire, as electric energy and communication body, is widely used in every field. Electric wire is adopted mostlyWith plastics and rubber, as insulation and sheath material, this type of polymeric material, after being heated, melting, decomposing, can produce combustibilityGas. When high temperature, these gases can react with oxygen and burn, and can produce a large amount of heat, and these heats can be urged when burningMake that polymer further melts, decomposition, sustained combustion, fire is expanded, thereby brings about great losses. China is only caused by cableFire damage, every year up to tens yuans.
Therefore,, along with the fire-retardant problem of electric wire more and more causes people's concern, people begin one's study various fire-retardantFire proofing material. In order to improve the fire resistance of electric wire, conventionally add halogenated flame retardant and obtain flame-proof cable material. But thisPlant flame-proof cable material and can produce a large amount of smog and hydrogen halide in the time of burning, easily make people be choked to death, cause secondary calamityDifficult. Therefore, the research of non-halogen flame-retardant cable development becomes current focus.
Ethylene propylene diene rubber (EPDM) is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, belongs to polyolefinFamily, its main polymer chain is completely saturated, this make it have superior anti-ozone, ageing-resistant, chemical resistance of concrete,Excellent insulating properties and fabulous vulcanization characteristics. Meanwhile, ethylene propylene diene rubber has lower proportion, can absorb a large amount ofFiller and oil and influencing characterisitic is little, can the cheap rubber compound of cost of manufacture.
EVM is the copolymer of ethene and vinyl acetate, is that high (mass fraction is 0.4～0. to vinyl acetate content8), amorphous copolymer that the degree of branching is high, belong to rubber, by the good vulcanizate of reasonable coordination availability. EVM'sMain chain is saturated structures, and chemical stability is good, and therefore it has excellent heat-resisting, resistance to ozone and weather resistance, the acetic acid of polarityVinyl acetate group makes it can tolerate non-polar oil and fuel oil.
The blending and modifying resin of ethylene propylene diene rubber and EVM, as CABLE MATERIALS, has not only improved the polarity of matrix resin, withShi Tigao the fire resistance of material, as application for a patent for invention 201310243481.4,201110244048.3,201210390599.5、201210393493.0、201310197441.0。
Because ethylene propylene diene rubber is nonpolar, though there is excellent ageing-resistant performance, swelling in non-polar oilProperty is large, and mechanical performance changes greatly. And EVM is due to the introducing of vinyl acetate groups, there is good oil resistivity, but ageing-resistantPerformance is undesirable. Meanwhile, ethylene propylene diene rubber and EVM are all not halogen-containing, but inflammable, once breaking out of fire can cause a large amount ofProperty loss and casualties.
Summary of the invention
The present invention, in order to solve the problems of the technologies described above, provides a kind of cable low-smoke non-halogen flame-retardant ageing-resistant CABLE MATERIALS.The present invention selects self burning not produce thick smoke, and between raw material, chemical reaction does not produce dense smoke, and raw material that can smoking, effectivelySmoke density while reducing cable fire.
For achieving the above object, the present invention adopts following technical scheme:
A kind of ageing-resistant CABLE MATERIALS of low-smoke non-halogen flame-retardant for cable, is characterized in that: by weight, and the composition bag of materialDraw together:
20～50 parts of ethylene propylene diene rubbers
EVM50～80 part
2.5～5 parts of vulcanizing agents
1.5～6 parts of auxiliary curing agents
2.0～8.0 parts, age resistor
10～30 parts, plasticizer
0.5～1.5 part of coupling agent
15～30 parts of reinforcing agents
20～40 parts of fillers
50～70 parts of fire retardants
According to regulation EN-50268-2, low cigarette refers to after product burns in closed container and sees through its light transmittance of Ray Of Light≧60%。
Ethylene propylene diene rubber of the present invention is the 3rd content of monomer at 0.2%～1.0% ethylene propylene diene rubber, MooneyViscosity is 25～30. The 3rd monomer of ethylene propylene diene rubber contains two keys, directly affects the ageing-resistant performance of rubber, of the present inventionThe 3rd content of monomer is low, good stability, ageing-resistant performance excellence; Select suitable Mooney viscosity simultaneously, be convenient to processing.
EVM of the present invention is vinyl acetate mass fraction in 40%～80% ethene and the copolymerization of vinyl acetateThing, Mooney viscosity is 20～30. Tensile strength is good, and oil resistance excellence is easy to processing.
Age resistor of the present invention is anti-aging agent RD or alkylated diphenylamine compound, and its object is to improve rubberHeat resistant performance.
Preferably, described age resistor is the age resistor XH-1 that Suqian Xu Bang development of chemical industry Co., Ltd produces. Efficient nothingPoison to by heat, light, ozone caused aging have special protective action and endurance effect, is prevented old effect under hot conditionsFruit and anti-tired effect are particularly outstanding.
Plasticizer of the present invention is a kind of in paraffin, trioctyl trimellitate (TOTM) (TOTM) or two kinds. Main usingImprove the plasticity of material, to reach good processing characteristics, simultaneously high temperature resistant, to reach good ageing-resistant performance. From addingWork aspect of performance is considered to use paraffin; From the viewpoint of ageing-resistant effect, can use trioctyl trimellitate (TOTM).
Fire retardant of the present invention is low-smoke non-halogen flame-retardant agent.
Preferably, described fire retardant is magnesium hydroxide. Magnesium hydroxide in whole fire-retardant process not only without any havingHarmful substances produces, and the product of its decomposition can also absorb in a large number the macromolecule such as rubber, plastics burning institute in fire-retardantThe pernicious gas and the smog that produce, activated magnesia constantly absorbs imperfect combustion fusing residue, from burning is stopped very soonOnly time, eliminate smog, stop molten drop, multiple performance is better than aluminium hydroxide, and safety is cheap, be a kind of emerging environment-friendly type withoutMachine fire retardant.
Vulcanizing agent of the present invention is cumyl peroxide (DCP), 1,1-dual-tert-butyl peroxy-3,3,5-front threeBasic ring hexane, dual-tert-butyl peroxy isopropyl base benzene.
Auxiliary curing agent of the present invention is triallylcyanurate (TAIC) or cyanuric acid tripropylene(TAC), its object is accelerated cure and strengthens cure efficiency.
Coupling agent of the present invention is silane coupling A-172. Improve the compatibility of various sizing materials, significantly improve and produceThe mechanical performance of product.
Beneficial effect of the present invention is:
