Preparation method of tough wear-resistant rubber and plastic product

The invention discloses a preparation method of a tough wear-resistant rubber and plastic product, which comprises the following steps: proportionally adding the raw materials into a mixer, and uniformly stirring to obtain a mixture; adding the mixture into a reaction kettle, mixing and reacting, extruding and granulating by using a double-screw extruder to obtain modified granules, and grinding the modified granules into powder; mixing polyurethane, the powder, a foaming agent and an emulsifying agent, putting the mixture into a stirrer, uniformly stirring, heating, foaming, and curing for 3-12h to obtain the tough wear-resistant rubber and plastic product. According to the method, the recycled waste PVC plastic is crushed and modified to serve as a production raw material, harmless and resource utilization of the waste plastic is achieved, shortage of plastic resources is relieved, and the method is environmentally friendly, free of pollution and nuisance, capable of being recycled and beneficial to the soc
