And by the material of above-mentioned formula ratio through banburying, open refining, then filter glue, compressing tablet, section or granulation and form.
In formula of the present invention, added the ester rubbers such as EVM, made rubber have more high elasticity and oil-proofness and the high feature of life-time service temperature grade, physical strength is also higher.
Various materials in the present invention in formula have good consistency and being uniformly distributed property of phase, and adhesion after lower or granulation easily stores.
Outlet electric cable of submersible pump prepared by the present invention is high with the temperature resistant grade of ethylene-propylene rubber sheath, is 150 ℃.200 ℃ of oil resistants.Easy moulding during the outlet electric cable of submersible pump ethylene-propylene rubber sheath of preparation, easily crosslinked.Processing performance is good.
Ethylene-propylene rubber(EPR) prepared by composition of the present invention is high temperature resistant, in the problem of oil resistant, make a breakthrough, make novel ethylene-propylene rubber(EPR) there is extremely excellent resistance to elevated temperatures and oil resistance, wear resisting property, the blend that ethylene-propylene rubber(EPR) and ethylene vinyl acetate rubber is base glue is take in the present invention, utilize ethylene vinyl acetate rubber splendid high temperature resistant and oil resistant characteristic, the high insulated electro performance of ethylene-propylene rubber(EPR), high flexibility, in formula, add consistency, the additive that phase is evenly distributed, finally make a kind of high temperature resistant 200 ℃, oil resistant grade is high, physical strength is large, be easy to machine-shaping, extrude ganoid mixed rubber, this mixed rubber meets the various performance requriementss of outlet electric cable of submersible pump completely.
