Abstract

The present invention provides a low-cost and good-performance rubber composite material and a preparation method thereof. The method provided by the present invention has characteristics of simple process and low cost, and is applicable for the industrial production. The composite material is prepared from the following raw materials, wherein the raw materials comprise, by weight, 60-70 parts of fluororubber, 10-15 parts of nitrile butadiene rubber, 1-2 parts of calcium hydroxide, 3-5 parts of magnesium hydroxide, 1-2 parts of micro crystalline wax, 1-2 parts of sulfur, 2-3 parts of dihydroxyhenzene, 1-2 parts of an accelerating agent N-cyclohexyl-2-benzothiazole sulfenamide C13H16N2S2 and 1-2 parts of an anti-aging agent N-phenyl-N'-yl-para-phenylenediamine. According to the present invention, the wear resistant rubber composite material has excellent wear resistance, the weight of the rubber composite material is lighter than the weight of the metal, such that the high-performance and wear-resistant rubber provided by the present invention can be widely applicable for the workplaces with requirements of wear resistance, high temperature resistance and low temperature resistance so as to substantially improve the service lives of the work-piece, the device and the like.

Description

technical field [0001] The invention relates to the field of rubber material processing, in particular to a fluorine-containing rubber valve body composite material and a preparation method thereof. Background technique [0002] Wear-resistant synthetic rubber materials are an important branch of wear-resistant materials, so the research on wear-resistant synthetic rubber materials has been paid attention to. CN200510048156.8 relates to a wear-resistant synthetic rubber material and a preparation method thereof. The wear-resistant synthetic rubber materials mainly include: natural rubber sheet, butadiene rubber, styrene-butadiene rubber, chlorinated polyethylene rubber, grease DOP, polytetrafluoroethylene, nano-magnesium hydroxide, oligoester, accelerator, supplement Strong agent, anti-vulcanization reducing agent, vulcanizing agent, filler. The above-mentioned raw materials can be obtained through processes such as masticating and mixing to obtain a Shore hardness of 60, ...
