The present invention provides sheath material, suitable for cable for rolling stock use, the material requirements have super oil resistant and
Resistance to ultralow temperature characteristics fully achieve GB 12528-2008 oil resistant requirements, while the sheath material makes under the conditions of -45 DEG C
With not embrittlement, there is preferable resistance to ultralow temperature performance.
The present invention is based on haloflexes to have good weather resistance, flame retardant property；And nitrile rubber is with excellent
Oil resistance；Ethylene propylene diene rubber has good weather resistance and low-temperature characteristics.Using haloflex as main material, chain
Chlorination section in section has certain polarity, has good compatibility with the nitrile rubber of polarity, adds a certain amount of butyronitrile rubber
Glue improves the oil resistance of formula；Polyethylene sections in its segment are nonpolarity, with a certain proportion of EPDM added
Rubber has good compatibility, thus improves the cryogenic property of formula system.
Compared with prior art, disclosed a kind of super oil resistant low temperature resistant cable sheath material, has following spy
Point：Its material cost is 1/3rd or so of chlorosulfonated polyethylene formula, and in resistance to 903# oil and resistance to -45 DEG C of ultralow temperature characteristics
Aspect be even more better than chlorosulfonated polyethylene, it is possible thereby to reduce the production cost of enterprise, meanwhile, excellent comprehensive performance and higher
Cost performance may insure that some defective works are no longer influenced by favor in the market, it is ensured that the cable for rolling stock is qualification
Product reduce security risk that may be present.
