Abstract

The invention discloses a modified butyl rubber sealing gasket material, which is characterized by being made of the following raw materials by weight part: 70-75 of butyl rubber (CBK139), 16-19 of EPDM, 34-38 of carbon black, 8-12 of hydroxyethyl methacrylate, 8-12 of isobutyl acrylate, 2-3 of magnesium oxide, 1-2 of Di-n-octyltin bis(isooctyl mercaptoacetate), 1-2 of calcium stearate, 1-2 of an anti-aging agent OD, 3-4 of a promoter DM, 1-2 of zinc oxide, 3-4 of soybean oil, and 10-12 of modified attapulgite. Modified attapulgite is added into the modified butyl rubber sealing gasket material provided by the invention to improve the technological performance of the rubber material, and environmental friendly compounding agents are used to reduce toxic and side effects and pollution to the environment. The modified butyl rubber sealing gasket material provided by the invention has the advantages of reasonable formula, simple process, low cost, good oil resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a modified butyl rubber sealing 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...
