Abstract

The invention provides a rubber composition for manufacturing the inner and outer rubber layers of the power steering high-pressure hose of an automobile and a production method for the rubber composition. The rubber composition comprises the following components: chlorinated polyethylene rubber, an acid absorption agent, an organic tin stabilizer, an anti-aging agent, a processing aid, a plasticizer, precipitated barium sulphate, carbon black, white carbon black, a binding agent RL, a crosslinking auxiliary and a peroxide crosslinking agent. According to the rubber composition for manufacturing the inner and outer rubber layers of the power steering high-pressure hose of the automobile, since the chlorinated polyethylene rubber is used, the manufacture cost is low; the acid absorption agent, the organic tin stabilizer and the anti-aging agent are added for protection, so that the rubber composition is endowed with excellent performance of resisting high temperature of 150 DEG C; the chlorinated polyethylene with proper chlorine content and precipitated barium sulphate are selected, so that the rubber composition is endowed with ATF220 oil swelling and extraction resistance; the binding agent RL and white carbon black are added into the formula, so that the chlorinated polyethylene rubber is promoted to be adhered to a fiber-reinforced layer, and that the rubber composition is not layered under the effect of high temperature and high pressure loads for a long time is ensured.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition for manufacturing an inner rubber layer and an outer rubber layer of an automobile power steering high-pressure hose and a production method thereof. Background technique [0002] The working temperature range of power steering high-pressure hose in automobiles is -40°C to +150°C, and the working pressure is 10.3MPa. The internal hydraulic fluid is ATF power steering oil, so the rubber composition of the inner rubber layer of the hose must withstand high temperatures of 150°C. And long-term oil resistance, the hose needs to withstand dynamic pressure loads, and also requires good adhesion between the rubber composition of the inner rubber layer and the outer rubber layer and the fiber reinforced layer, so as to ensure excellent comprehensive performance. The main material of the rubber composition of the inner rubber layer and the outer rubber layer of the current powe...
