Description

technical field [0001] The invention relates to the technical field of polymer modified plastics, in particular to a wear-resistant modified plastic and its manufacturing process. Background technique [0002] Plastics are polymer compounds made of monomers through addition polymerization or polycondensation. The main component is resin, which is widely used in many fields; plastics are widely used because of their advantages such as lightness and good physical properties. Used in the current door and window field, the common ones are PE, PP, PVC and PPR, etc.; the threshold in the field of moving doors is often made of plastic, and some moving doors move the door body by setting pulleys and guide rails below, and the other part directly passes through the A chute is set under the door panel to move the door. When these structures are in use, the plastic is often fluffed and dented due to long-term friction, which greatly increases the friction between the door, window and g...
