Abstract

The invention discloses an elastic modified acrylonitrile-butadiene rubber sealing gasket material. The material is characterized by being prepared from the following raw materials in parts by weight: 85-90 parts of acrylonitrile-butadiene rubber (N41), 10-12 parts of thermoplastic elastomer (SBS), 10-13 parts of thermoplastic elastomer (SIS), 1-2 parts of ammonium fluoride, 1-2 parts of sodium monofluorophosphate, 15-25 parts of N660 carbon black, 1-2 parts of calcium-zinc stabilizer, 10-15 parts of propanediol sebacate polyester, 1-2 parts of sulfur, 1-2 parts of bisphenol A, 1-2 parts of accelerant DTDM (4,4'-dithiodimorpholine), 3-5 parts of tributyl citrate, 30-35 parts of N330 carbon black, 10-12 parts of fast extruding furnace black and 10-12 parts of modified attapulgite clay. The material has the excellent effects that the processing properties of the rubber material are improved by adding the modified attapulgite clay; the toxic and side effects and environmental pollution of the material are reduced by using an environment-friendly compounding agent; the material has high elasticity, good wear resistance, good ageing resistance, good sealing property, simple process and long service life, and is low in cost.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to an elastically 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 priorit...
