Description

A kind of cable sheath rubber
Technical field
The present invention relates to a kind of cable sheath rubber, belong to the rubber technology field.
Background technology
Chlorinatedpolyethylene (CM/CP) main application abroad is to make cable.CM has the performance close with chlorosulfonated polyethylene with neoprene, but CM is difficult for incipient scorch, and processing characteristics is good, no roll banding phenomenon.CM has stability preferably to chromic acid, clorox and strong oxidizing property pharmaceutical chemicals, and anti-mineral oil is functional.Normally used CM cl content has the characteristic of rubber like between 30%~40%, along with the raising of cl content, the extrusion performance of CM and oil resistant, wear-resisting, flame retardant properties obtain corresponding improvement, and elasticity and winter hardiness descend.
Summary of the invention
The purpose of this invention is to provide a kind of cable sheath rubber of fuel oil resistance, anti-mineral oiliness, lower temperature resistance and resistance to heat aging preferably that has simultaneously.
In order to achieve the above object, the invention provides a kind of cable sheath rubber, it is characterized in that its raw material comprises:
Chlorinatedpolyethylene 100 weight parts;
Organic peroxide sulfuration agent 2~6 weight parts;
Help sulphur agent 3~6 weight parts;
Anti-aging agent 0.5~1.5 weight part;
Fire retardant 10~30 weight parts;
Strengthening agent 20~40 weight parts.
Preferably, described chlorinatedpolyethylene is an EXT1000(Dow Chemical).
Preferably, described organic peroxide sulfuration agent is dicumyl peroxide (DCP).Vulcanizing agent dicumyl peroxide and cooperation can improve degree of crosslinking after helping the sulphur agent, can give the good heat-proof aging of cross-linked rubber, oil-proofness.
It is preferably, described that to help the sulphur agent be iso-cyanuric acid triallyl ester (TAIC).Iso-cyanuric acid triallyl ester can be accelerated vulcanization rate, improves cross-linked speed, shortens curing time.
Preferably, described anti-aging agent is 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymkeric substance (RD).RD is a kind of ketoamine class anti-aging agent, protection to thermo-oxidative ageing is very effective, and toxicity is little, can suppress the catalyzed oxidation of the harmful metal ions such as copper of harshness, be suitable as elastomeric oxidation inhibitor, also aging, the thermal ageing of climate protection and the be full of cracks that circumnutates effectively.
Preferably, described fire retardant is decabromodiphynly oxide and antimonous oxide.Decabromodiphynly oxide, mainly as additive flame retardant, brominated amount is big, Heat stability is good, flame-retarded efficiency height, it has higher bromine content and good thermostability, is a kind of nontoxic, free of contamination efficient flame-retarding agent.Then there are good synergistic antimonous oxide and halogen thing and time spent, and flame retardant effect obviously improves.
Preferably, described strengthening agent is carbon black N550.Carbon black N550 is the furnace black with medium strengthening action, and particle surface is smooth, can give sizing material with higher very property, extruder rate is fast, the extrudate smooth surface, its other soft carbon of reinforcement energy force rate is all high, can give cross-linked rubber good temperature resistance, wear resistance and thermal conductivity.
Preferably, described cable sheath rubber raw materials also comprises:
Nanometer potter's clay 40~80 weight parts;
Extra light calcined magnesia 10~20 weight parts;
Chlorinated paraffinic oil 10~20 weight parts;
Dioctyl sebacate 10~20 weight parts;
Microcrystalline Wax 5~10 weight parts;
Lead stearate 3~7 weight parts;
Silane coupling A-172 0.5~1.5 weight part.
Wherein, extra light calcined magnesia and lead stearate are promoting agents, are processing aid, and lead stearate also has the softening and effect on thermal of plasticising.Chlorinated paraffinic oil are chlorinated derivatives of paraffinic hydrocarbon, have low volatility, fire-retardant, electrical insulating property is good, advantage such as inexpensive, can be used as fire retardant.Dioctyl sebacate (DOS) is a kind of good cold resistant plasticizer, the plasticizing efficiency height, and volatility is low, has both had good winter hardiness, and better heat-resisting, photostabilization and electrical insulating property are arranged again.Vinyl three ('beta '-methoxy oxyethyl group) silane (claiming silane coupling A-172 again) uses as coupling agent.
The present invention makes rubber have good thermal ageing by add elasticity and the winter hardiness that a certain amount of auxiliary agent improves rubber unvulcanizate in mixing process simultaneously, has realized the balance of heat-resisting, low temperature resistant and oil resistance, the mechanical and physical performance excellence.
Advantage of the present invention is as follows:
1, You Yi fuel oil resistance, anti-mineral oil performance and the later low-temperature performance of heat-proof aging.
2, can fill more filler and have good compression deformation performance and toughness.
3, slick apparent characteristic has excellent process industrial art performance.
4, excellent flame-retardant.
