Abstract

The invention discloses a Y-shaped ring rubber material for automobiles. The Y-shaped ring rubber material is made from the following raw materials in parts by weight: 30-40 parts of fluorosilicone rubber, 30-40 parts of polyepichlorohydrin rubber T3100, 20-30 parts of chlorosulfonated polyethylene rubber TS-340 (Tosoh), 8-11 parts of polyisobutylene, 12-15 parts of modified tree ashes, 2-3 parts of ferrocene, 0.2-0.6 part of dicumyl peroxide (DCP), 35-40 parts of quick-extruded carbon black N660, 20-25 parts of fumed silica, 4-6 parts of zinc oxide, 10-12 parts of dolomite, 10-12 parts of bauxite, 14-16 parts of modified iron ore tailing powder, 0.1-0.3 part of accelerant CZ, 0.2-0.4 part of accelerant DETU (Diethyl Thiourea), 1-2 parts of sodium stearate, 1-2 parts of anti-aging agent ODA, 1-3 parts of aminopropyl triethoxysilane and 5-7 parts of saponite. The rubber material disclosed by the invention has excellent resistance to high / low temperature, oil, solvents and chemicals; and meanwhile, the mechanical property is good.

Description

technical field [0001] The invention relates to the field of synthetic rubber, in particular to an automobile Y-ring rubber compound and a preparation method thereof. Background technique [0002] Fluorosilicone rubber has excellent high and low temperature resistance, oil resistance, solvent resistance and chemical resistance. A new type of low temperature sealing material and fuel oil hose. [0003] In the prior art, a basic fluorosilicone raw rubber is used to prepare fluorosilicone compounded rubber through mixing. Due to the different molecular weight distribution and average molecular weight of different fluorosilicone raw rubber, the properties of fluorosilicone rubber compounded by mixing a single raw rubber are different. The high molecular weight of raw rubber has good tensile strength and tear strength. Good oil resistance, but poor processability and difficult mixing. The low molecular weight of raw rubber makes it difficult to have good tensile strength and t...
