Abstract

The invention discloses a modified alum-containing rubber seal ring material and a preparation method thereof. The material is prepared from the following raw materials: chloroprene rubber CR322, carbon black N339, accelerant CZ, alumina, crosslinking agent TAIC, antioxidant 1010, modified alum, tributyl citrate and sodium laurylsulfate. The material is prepared by adopting choroprene rubber CR322 as a main material, is low in price, has good performances of heat resistance, oil resistance and flame retardance; the modified alum is added in the raw materials, so that the internal binding force of the rubber seal ring can be enhanced, and the tensile strength, aging resistance, wear resistance, heat resistance, metal binding property, mechanical performance of the rubber seal ring can be effectively improved.
