Abstract

The invention discloses a modified fluororubber sealing gasket material which is characterized by being prepared from the following raw materials in parts by weight: 65-70 parts of fluororubber, 3-4 parts of graphite, 10-12 parts of phenolic resin, 2-3 parts of silane coupling agent KH-550, 4-6 parts of dibutyl phthalate, 2-3 parts of polyisobutene, 2-5 parts of diethylene glycol benzoate, 2-3 parts of magnesium oxide, 2-3 parts of zinc oxide, 1-2 parts of anti-aging agent ODA, 1-2 parts of accelerant CZ, 1-2 parts of monobutyl tin oxide, 1-2 parts of sulfur, 30-35 parts of N550 carbon black, 10-12 parts of calcium carbonate powder, 15-18 parts of nano clay and 10-12 parts of modified attapulgite clay. Due to the added modified attapulgite clay, the process performance of the size is improved, and the toxic and side effects and environmental pollution are reduced by using an environment-friendly compounding agent. The modified fluororubber sealing gasket material has high sealing property, compression resistance, ageing resistance, oil resistance and friction resistance.

Description

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