Abstract

The invention discloses a modified nitrile rubber packing pad material, which is characterized by comprising the following raw materials by weight: 90-110 parts of nitrile rubber, 3-5 parts of polyimide resin, 1-3 parts of zinc borate, 4-5 partsof magnesium carbonate, 2-3 parts of 3-aminopropyltrimethoxysilane,1-2 parts of cross-linking agent TAC, 1-2 parts of anti-aging agent 4010 NA, 1-2 parts of anti-aging agent OD, 6-8 parts of polyethylene terephthalate, 3-4 parts of accelerant DM, 2-5 parts of n-butyl methacrylate, 2-5 parts of zinc oxide, 42-46 parts of N550 carbon black, 24-28 parts of nano sepiolite powder and 10-12 parts of modified attapulgite. The modified attapulgite improves the technology performance of a rubber compound, the toxic and side effect as well as environmental pollution can be reduced by using an environment friendly compounding ingredient. The modified nitrile rubber packing pad material has the advantages of good sealing performance, oil resistance, corrosion resistance, simple process and low cost.

Description

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