Abstract

The invention discloses a silicon carbide powder reinforced high-performance plastic and a preparation method thereof. Raw materials of the silicon carbide powder reinforced high-performance plastic include, by weight, 65-70 parts of polytetrafluoroethylene, 10-15 parts of silicon carbide powder, 5-10 parts of a reagent graphite, 2-5 parts of molybdenum disulfide, 2-5 parts of bronze powder, 1-2 parts of carbon fiber powder and 1-2 parts of glass fiber powder. The preparation method comprises the following steps: (1) raw material weighing; (2) mixing, and drying; (3) hot pressing forming; and(4) preparation of the finished product. The preparation method of the high-performance plastic has the advantages of simple process, reasonable steps, and convenience in promotion and application, and the prepared plastic has the advantages of good physical and mechanical properties, excellent anti-friction and anti-wear performances, strong chemical stability, and great market competitiveness and production practical values.

Description

technical field [0001] The invention relates to the technical field of high-performance plastics, in particular to a silicon carbide powder-reinforced plastic material and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. At present, many plastics have poor friction and wear resistance, which limits their application in specific environments. Contents of the invention [0003] The purpose of the present invention is to propose a high-performance wear-resistant plastic preparation method for the problem of poor wear resistance of plastics. [0004] The present invention is achieved th...
