Abstract

The invention discloses a modified compounded rubber sealing gasket material. The modified compounded rubber sealing gasket material is characterized by being prepared from the following raw materials in parts by weight: 70-75 parts of tetrafluoroethylene-propylene rubber, 18-23 parts of silicone rubber, 1-2 parts of calcium hydroxide, 2-4 parts of magnesium oxide, 28-32 parts of N550 carbon black, 1-2 parts of sulphur, 1-2 parts of accelerant DM, 2-3 parts of zinc oxide, 2-4 parts of potassium citrate, 1-2 parts of 2,2',3,3',4,4',5,5',6,6'-decabromobibenzyl, 1-2 parts of acrylonitrile, 3-5 parts of methyl methacrylate, 1-2 parts of 3-aminopropyltrimethoxysilane, 0.5-1 part of crosslinking agent TAC, 16-20 parts of nanometer celestite powder 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 compounded rubber sealing gasket material has good combination property and is long in service life; the mechanical property, the oil resistance, the ageing resistance and the like of the modified compounded rubber sealing gasket material are improved.

Description

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