Abstract

The invention relates to the field of rubber and in particular relates to a high-performance hydrogenated nitrile rubber material and a preparation method thereof. The high-performance hydrogenated nitrile rubber material provided by the invention is prepared from hydrogenated nitrile rubber and hydrogenated nitrile rubber emulsion as main raw materials, wherein the weight ratio of the hydrogenated nitrile rubber to the hydrogenated nitrile rubber emulsion is (6-30):(1-10), preferably (10-15):(4-7). The preparation method of the high-performance hydrogenated nitrile rubber material comprises the following step: performing wet-method mixing or dry-method mixing on a hydrogenated nitrile rubber emulsion, a hydrogenated nitrile rubber emulsion, an anti-aging agent 4010A, zinc oxide, stearic acid, carbon black N220 and DCP (dicumyl peroxide) so as to obtain mixed rubber. The high-performance hydrogenated nitrile rubber material provided by the invention adopts hydrogenated nitrile rubber which is prepared by using a solution hydrogenation method and hydrogenated nitrile rubber which is prepared by using an emulsion hydrogenation method as raw materials, not only is the performance of the hydrogenated nitrile rubber improved, but also the use cost of the hydrogenated nitrile rubber can be lowered.

Description

Technical field [0001] The invention relates to the field of rubber, in particular to a high-performance hydrogenated nitrile rubber material and a preparation method thereof. Background technique [0002] Hydrogenated nitrile rubber (HNBR) is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber (NBR). HNBR has good oil resistance; and due to its highly saturated structure, it has a good High heat resistance, excellent chemical resistance, excellent ozone resistance, high compression set resistance; at the same time, hydrogenated nitrile rubber also has high strength, high tear performance, excellent wear resistance, etc. One of the rubbers with excellent comprehensive performance. The current preparation method is usually prepared by solution hydrogenation. The solution hydrogenation process involves high temperature and high pressure, precious metal catalysts, and high cost, which limits its wide application.
