Problems solved by technology

[0002] In pipeline transportation in oil fields, the transported medium is a mixture of oil and ore, so the rubber used for the pipeline bushing is usually natural rubber containing tread rubber. Although the above rubber has wear resistance, its oil resistance is very poor. , its oil resistance can only reach more than 15%

Abstract

The invention relates to an oil-resistant rubber cushion which comprises 90 parts of ethylene propylene diene monomer, 75 parts of tetrapropyl fluororubber, 7 parts of calcium carbonate, 3 parts of dibenzothiazyl disulfide, 5 parts of paraffin and 6 parts of plasticizing and softening agent. The rubber pipe clamp also comprises 3 parts of stearic acid. The rubber pipe clamp also comprises 5 parts of tetraethylthiuram disulfide. Compared with the prior art, the high-temperature-resistant rubber foot pad enhances the oil resistance of the natural rubber to 8-10%, and has favorable heat resistance and air tightness.

Description

technical field [0001] The invention relates to a rubber product, in particular to an oil-resistant rubber cushion. Background technique [0002] In pipeline transportation in oil fields, the transported medium is a mixture of oil and ore, so the rubber used for the pipeline bushing is usually natural rubber containing tread rubber. Although the above rubber has wear resistance, its oil resistance is very poor. , its oil resistance can only reach more than 15%. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-resistant rubber cushion. [0004] In order to solve the above technical problems, the oil-resistant rubber cushion of the present invention comprises the following components, 90 parts of EPDM rubber, 75 parts of tetrapropylene fluorine rubber, 7 parts of calcium carbonate, 3 parts of dibenzothiazole disulfide, paraffin wax 5 parts, 6 parts of plasticizing softener. [0005] The rubber clamp also ...
