Wear-resistant and corrosion-resistant mould material

Abstract

The invention discloses a wear-resistant and corrosion-resistant mould material which is prepared from the following materials by mass percent: 30-40% of polyurethane resin modified by organic silicon, 10-20% of butyl methacrylate, 3-5% of a plasticizer, 3-5% of a surface active agent, 3-5% of silicon carbide, 3-5% of graphite, 3-5% of montmorillonite, 1-3% of a curing agent and the balance of water. According to the scheme, the polyurethane modified by organic silicon is taken as a base material, and isocyanate is taken as the curing agent in a matching way, so that the molded mould material has excellent toughness and processing performance, and the service life is remarkably prolonged; the silicon carbide and yttrium oxide are fed into the mould material, so that the wear resistance and the corrosion resistance of the material are improved, the material has better stability and environmental compatibility, and the service life of a mould is prolonged; the nanoscale powdered graphite is fed into the material, so that the heat conduction speed is accelerated, and the material has excellent heat transfer performance and resistance to heat and humidity.

Description

technical field [0001] The invention relates to the field of engineering material processing, in particular to a wear-resistant and corrosion-resistant mold material. Background technique [0002] Mold is an important process equipment in all sectors of the national economy and enjoys the reputation of "mother of industry". Mold molding has many advantages such as high efficiency, good quality, saving raw materials, and reducing costs. According to statistics, more than 60% of the parts of airplanes, tanks, automobiles, tractors, electrical appliances, instruments and meters, etc., and more than 85% of the parts of bicycles, washing machines, refrigerators, electric fans, air conditioners, cameras, etc. Mold production. Without molds, there would be no modern industrial development. All countries in the world attach great importance to the mold industry. [0003] Factors that affect the service life of the mold include: design structure, forming and manufacturing process,...
