Problems solved by technology

[0002] In recent years, with the continuous improvement of the automotive industry's requirements for reliability and safety, fluororubbers have become more and more widely used in automobiles, and their performances are also different in addition to oil resistance. For example, fluororubber in the inner layer of fuel hoses The material must have high thermal oxidation resistance, the turbocharger hose must have high strength and high temperature resistance; it must have low temperature resistance when used in severe cold areas, and for example, the engine oil seal must have high wear resistance and toughness requirements, in order to achieve better performance requirements, the above-mentioned components are gradually replaced by fluororubber materials with better performance. The fluororubber materials play a role that cannot be ignored in the automotive field. Fluorine rubber materials, it is difficult to have multiple performance requirements such as high and low temperature resistance, high strength, high wear resistance and resistance to various automotive chemical media.

Abstract

The invention discloses a fluororubber and hydrogenated butadiene-acrylonitrile rubber blending material. The fluororubber and hydrogenated butadiene-acrylonitrile rubber blending material consists of the following raw materials in parts by weight: 70 to 90 parts of fluororubber, 10 to 30 parts of hydrogenated butadiene-acrylonitrile rubber, 5 to 30 parts of a reinforcing filler, 1 to 2 parts of a peroxide vulcanizing agent, 2 to 10 parts of an acid-absorbing agent and 0.5 to 2 parts of crosslinking aid. By adoption of the formula, the fluororubber and hydrogenated butadiene-acrylonitrile rubber blending material is prepared by utilizing high-temperature resistance and excellent performance of resisting various mediums of the fluororubber, utilizing low-temperature resistance, excellent oil resistance and high strength of the hydrogenated butadiene-acrylonitrile rubber, and adding the filler, the peroxide vulcanizing agent, the acid-absorbing agent and the crosslinking aid with proper proportion, on one hand, the fluororubber and hydrogenated butadiene-acrylonitrile rubber blending material has very high high-temperature and low-temperature resistance and very high performance of resisting various chemical mediums, in particular oil-resistant characteristic, and on the other hand, the strength is very high, and the wear resistance and the toughness are high through reasonable addition of the additives, so various performance requirements of heat resistance, cold resistance, chemical medium resistance and improving strength and wear resistance are met.
