Abstract

The invention discloses a high-strength AEM and FKM combined rubber compound preparation method, and specially relates to the field of rubber compound production, wherein the raw materials comprise, by weight, 80-120 parts of an acrylate rubber, 16-24 parts of a fluororubber, 3-8 parts of carbon black, 1.5-4 parts of white carbon black, 8-12 parts of a silane coupling agent and 0.5-3 parts of an anti-aging agent. The specific processing steps comprise: plasticizing, mixing, and tabletting forming. Acording to the invention, an acrylate rubber is used as a main body, and a fluororubber, carbonblack, white carbon black, a silane coupling agent and an anti-aging agent are added, so that the rubber surface wear resistance and the rubber surface tearing strength of the rubber compound preparedby the method are improved to a certain extent compared with the rubber surface wear resistance and the rubber surface tearing strength of AEM so as to obtain the high strength rubber compound; and by calculating the reduced cost due to the adding of the FKM complex material during the preparation according to the market value under the normal condition, the cost of the rubber compound prepared by using FKM accounting for about 20% of the mass of AEM can be saved by up to 15% compared with the cost of the rubber compound prepared by using AEM.

Description

Technical field [0001] The present invention relates to the technical field of rubber production. More specifically, the invention relates to a method for preparing a high-strength AEM and FKM combined rubber. Background technique [0002] Acrylic rubber (hereinafter referred to as AEM) is an elastomer obtained by copolymerization of acrylic ester as the main monomer, the main chain of which is saturated carbon chain, and the side groups are polar ester groups. Due to its special structure, it has many excellent characteristics, such as: heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc., its mechanical properties and processing properties are better than fluorine rubber and silicone rubber, and its heat resistance, aging resistance and oil resistance Better than nitrile rubber. AEM is widely used in various high-temperature and oil-resistant environments, and has become a sealing material that has been developed and promoted by the automoti...
