Abstract

The invention discloses a silicon carbide reinforced high-performance rubber material and a preparation method thereof. The rubber material is characterized by being prepared from the following raw materials in parts by weight: 65-70 parts of nitrile rubber, 20-25 parts of silicon carbide powder, 1-2 parts of sulfur, 2-4 parts of attapulgite, 1-2 parts of microcrystalline wax, 0.5-1.5 parts of vaseline, 3-5 parts of polyethylene glycol, 0.2-0.4 part of an anti-aging agent, 0.5-1 part of accelerant and 0.1-0.3 part of ultraviolet absorbent. The preparation method comprises the following steps:(1) weighing raw materials; (2) plastifying; (3) mixing; and (4) preparing the finished product. The preparation method is simple in process and reasonable in steps, and is convenient for popularizingand applying; and the rubber material has excellent physical and mechanical performance, excellent friction and abrasion resistance and strong chemical stability, and extremely has market competitiveness and production practical value.

Description

technical field [0001] The invention relates to the technical field of high-performance rubber, in particular to a silicon carbide powder-reinforced rubber material and a preparation method thereof. Background technique [0002] In recent years, with the development of rubber products used in the fields of automobiles, machinery, aviation, aerospace, and chemicals to high performance, low energy consumption, and long life, general-purpose rubbers such as natural rubber, neoprene, and nitrile rubber have been unable to meet the needs of new types of rubber. The requirements of wear resistance and other aspects of accessories limit its further application in the mechanical seal industry. Contents of the invention [0003] The object of the present invention is to solve the problem of poor wear resistance of rubber, and propose a high-performance wear-resistant rubber material and a preparation method thereof. [0004] The present invention is achieved through the following ...
