High abrasion resistant crushing knife for plastic bottle crusher

The invention relates to a high abrasion resistant crushing knife for a plastic bottle crusher. The high abrasion resistant crushing knife for the plastic bottle crusher is characterized in that the high abrasion resistant crushing knife is prepared from the following components in parts by weight: 45-55 parts of tungsten carbide, 10-20 parts of silicon carbide, 4-6 parts of metallic indium, 0.5-2 parts of organic selenium powder, 1.5-3 parts of calcined kaolin, 1-3 parts of potassium phosphotungstate, 2-4 parts of amorphous state silicon dioxide, 0.5-2 parts of grapheme, 4-6 parts of carbon powder, 0.5-2 parts of metallic molybdenum, 1-3 parts of metallic titanium, 0.5-2 parts of zirconium oxide, 1-3 parts of polyoxyethylene resin, and 1-3 parts of metallic magnesium. The amorphous state silicon dioxide is added in the traditional formula, and the glossiness of the knife can be improved; the polyoxyethylene resin is used as adhesive, grapheme, selenium powder and other nonmetal components are added, the abrasion resistance of the knife can be improved and the service life of the knife can be prolonged.
