Abstract

The invention discloses a multi-rubber compounded sealing gasket material. The invention is characterized in that the material is prepared from the following raw materials in parts by weight: 40-45 parts of butyl rubber (CBK139), 14-18 parts of silicon rubber, 32-35 parts of fluororubber, 4-5 parts of turpentine, 1-2 parts of orchid essential oil, 3-4 parts of manganese peroxide, 2-3 parts of aluminum stearate, 2-4 parts of rapeseed oil, 1-2 parts of silane coupling agent KH550, 1-2 parts of accelerator DM, 3-4 parts of zinc oxide, 1-2 parts of magnesium oxide, 1-2 parts of anti-scorching agent CTP, 1-2 parts of accelerator CZ, 12-15 parts of aluminum oxide, 15-20 parts of nano calcium carbonate, 24-28 parts of N220 carbon black and 10-12 parts of modified attapulgite. The modified attapulgite is added to improve the technical properties of the rubber material; and the environment-friendly compounding agent is utilized to reduce the toxic or side effect and environmental pollution. The material has the advantages of favorable processability, high oil resistance, high corrosion resistance and high elasticity.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a variety of rubber mixing gasket materials 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 of th...
