Abstract

The invention discloses a rubber sealing pad material with wear resistance and sealing performance. The rubber sealing pad material is characterized by comprising the following materials in parts by weight: 70-75 parts of acrylate rubber, 20-25 parts of chloroprene rubber (CR121), 24-28 parts of N330 carbon black, 12-18 parts of nano mica, 2-3 parts of benzotriazole, 2-3 parts of polyethylene glycol, 1-2 parts of cobalt naphthenate, 1-2 parts of calcium stearate, 10-15 parts of N660 carbon black, 20-25 parts of nano clay, 1-2 parts of aluminate coupling agent DL-411, 1-2 parts of accelerant, 1-2 parts of sulphur, 2-3 parts of zinc oxide and 10-12 parts of modified attapulgite. The rubber sealing pad material disclosed by the invention has the advantages that due to addition of the modified attapulgite, the process properties of rubber are improved; due to use of an environment-friendly compounding agent, the toxic and side effects and the pollution to the environment are reduced; the formula is reasonable, the process is simple, the cost is low, the sealing performance and the wear resistance are good and the ageing resistance is good.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a wear-resistant sealing rubber gasket material and a preparation method thereof. Background technique [0002] Gasket is a material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently used are mostly rubber gaskets, which are characterized by high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation performance. Widely used in defense industry and civilian industry. However, the existing rubber gaskets have defects such as unsatisfactory sealing effect, poor wear resistance and low strength, which are far from meeting the actual requirements. Therefore researching and developing a kind of high-performance rubber gasket has become the task of top priority. Contents o...
