介绍目前废旧塑料回收再利用技术的主要方法和不足之处，提出基于机械物理法的热固性塑料回收再利用方法，确定热固性塑料回收再利用的工艺流程。通过对热固性酚醛塑料回收再生试验，验证了机械物理法回收再生的可行性，最后对再生试样进行力学性能测试。结果表明，回收再生酚醛/聚丙烯共混料的拉伸强度与弯曲强度分别达到6 MPa和13 MPa以上，能满足回收再利用的要求。

Main methods and shortcomings about recycling technology of waste plastics were introduced,and the recycling mechanism of the waste thermosetting plastics based on mechanical and physical method was presented. Accordingly,the recycling process of waste thermosetting plastics was determined. By means of recycling and regeneration experiment on thermosetting phenolic plastics,the feasibility of recycling and regeneration based on mechanical and physical method was verified.At last,the mechanical properties of regeneration specimens were tested. The results show that tensile strength and bending strength of recycling phenolic/polypropylene plastics can reach 6 MPa and 13 MPa respectively,and it meets the recycling requirements.
