Abstract

The invention discloses a modified butyl rubber sealing gasket material. The modified butyl rubber sealing gasket material is characterized by being prepared from the following raw materials in parts by weight: 60-65 parts of butyl rubber (BBK232), 15-20 parts of SG-4 type PVC (polyvinyl chloride) resin, 6-8 parts of triethyl citrate, 1-2 parts of epoxy butyl oleate, 1-2 parts of sulfur, 1-2 parts of accelerant TMTM, 18-22 parts of rutile titanium dioxide, 2-5 parts of 1-bromine-3-methyl-2-butene, 1-2 parts of trifluoroacetylacetone holmium, 20-25 parts of bauxite powder, 10-15 parts of N339 carbon black, 1-2 parts of titanate coupling agent TMC-TTS, 1-2 parts of antioxidant 1010 and 10-12 parts of modified attapulgite. The processing property of the rubber material is improved by adding the modified attapulgite; the toxic and side effects and the pollution to environments of the rubber material are reduced by using an environmentally-friendly compounding agent; the modified butyl rubber sealing gasket material is reasonable in formula, simple in process and low in cost and has good oil resistance, ageing resistance and insulativity, and the quality of products is stable.

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...
