Abstract

The invention provides a hydrogenated butadiene-acrylonitrile rubber-ethylene vinyl acetate elastomer-surlyn blended thermal-resistant oil-resistant hose rubber material. The hydrogenated butadiene-acrylonitrile rubber-ethylene vinyl acetate elastomer-surlyn blended thermal-resistant oil-resistant hose rubber material comprises 70 to 95 parts of hydrogenated butadiene-acrylonitrile rubber, 5 to 30 parts of sodium acrylate ionic bond polymer, 15 parts of ethylene vinyl acetate elastomer, 5 parts of zinc oxide, 0.4 to 0.6 part of sulphur, 2 to 2.5 parts of vulcanization accelerator TMTD, 2.5 parts of vulcanization accelerator MBS, 3 to 4.5 parts of accelerant 3M, 70 parts of a reinforcing agent, 15 to 20 parts of a softener, 5 parts of a tackifying resin, and 3 parts of an antioxidant. The hydrogenated butadiene-acrylonitrile rubber-ethylene vinyl acetate elastomer-surlyn blended thermal-resistant oil-resistant hose rubber material is obtained via blending of sodium acrylate ionic bond polymer elastomer, ethylene vinyl acetate elastomer, and hydrogenated butadiene-acrylonitrile rubber, and possesses excellent mechanical properties, oil resistance, and aging resistance.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a rubber material for heat-resistant oil rubber hoses and a preparation method thereof. Background technique [0002] With the development of modern industry, the requirements for the oil resistance, heat resistance and chemical corrosion resistance of the rubber used in the fuel and lubrication system of automobiles and equipment are getting higher and higher. Compared with the chlorinated polyethylene used in the traditional oil-resistant hose Rubber or fluororubber, hydrogenated nitrile rubber not only has good oil resistance, but also has better mechanical strength, heat resistance and chemical corrosion resistance, so it has been widely used in the field of hose rubber in recent years. [0003] The quality of oil-resistant hose rubber is one of the main factors affecting the performance of the product, which mainly includes the requirement that the rubber has good heat ...
