Abstract

The invention relates to the technical field of rubber, specifically to a preparation method for a rubber material applied to a low-temperature protective sleeve with sponge used for an oil inlet pipeof a steering oil pump. The preparation method comprises the following concrete steps: weighing components according to a formula; separately plasticating nitrile rubber and ethylene propylene rubber, then carrying out mixing, adding a reinforcing agent, carrying out mixing so as to obtain blended rubber, adding sulfur, a promoter, a silane coupling agent, a plasticizer and an antioxidant into the blended rubber, and carrying out vulcanizing so as obtain the desired rubber material. The preparation method of the invention has the following advantages: through reasonable design of the formulaand component contents and vulcanization twice, excellent oxidation resistance and anti-aging properties of the rubber material are realized; meanwhile, the use of an anti-aging agent can be avoided;and performances of the rubber material are comprehensively enhanced.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a method for preparing a rubber material for a low-temperature sheath with a sponge for an oil inlet pipe of a steering oil pump. Background technique [0002] Due to the sheath of the oil inlet pipe of the steering oil pump, it is subjected to relatively high pressure and has harsh working conditions. The properties of the rubber material of the low-temperature sheath in the prior art are poor and cannot really meet its needs, causing it to be easily aged and damaged, which affects its service life. Contents of the invention [0003] The object of the present invention is to provide a preparation method of a rubber compound for a low-temperature sheath with a sponge for the oil inlet pipe of a steering oil pump with strong anti-aging performance in order to solve the above-mentioned technical deficiencies. [0004] In order to achieve the above object, the preparation method o...
