The material is prepared by using monomer raw materials through synthesis or condensation reaction polymerization, and consists of synthetic resin, fillers, plasticizers, stabilizers, lubricants, pigments and other additives. Plastics are largely classified into thermoplastic types and thermosetting types. The thermoplastic type is that the material can be softened after being heated and can be hardened into a required shape after being cooled, and the material can be repeatedly softened and molded. The thermosetting type can be coagulated into a certain shape after being heated, the internal structure of the molecule can be damaged after being reheated to a certain degree, one or more elements in the thermosetting type can be released, and the thermosetting type can become other synthesized bodies. The plastic powder obtained by the crushing process can be realized by most plastics, and some plastics are subjected to friction, impact, tearing and the like by a crusher at normal temperature to obtain 200-micron fine powder, such as plastics with higher glass transition temperature. However, most plastics generate enough heat during the crushing process to melt and re-bond the plastics together, which can cause energy to be trapped in the crushing process.
