| abstract |
The invention discloses a kind of brake of electric vehicle pincers seal of high cold resistance, it is related to seal technical field, is made up of following component：Nitrile rubber, butadiene rubber, silica, rare earth, carbon black, plasticizer, glass dust, magnesia, etherification starch, dioctyl adipate, aluminum oxide, filler；The brake of electric vehicle pincers seal of high cold resistance prepared by the present invention, using nitrile rubber and butadiene rubber as main component, by adding rare earth and etherification starch, effect is crosslinked to rubber, it is more more stable than the cross-linked network of sulfur cross-linking to form stable rubber cross network, it can significantly improve the chemical bond energy of rubbery system, so that the cold resistance of brake of electric vehicle pincers seal made of greatly improving. |
