Abstract
The invention is aimed to provide a waste polyvinyl chloride recycled material for modifying the defects of a polyvinyl chloride material, and a preparation method thereof. The polyvinyl chloride (PVC) is one of five general synthetic resins in synthetic materials; the yield of the PVC is next only to polyethylene, and comes in second; the PVC is one of the most popular plastic in the world at present, and is widely applied in building industry, packing materials, household daily articles and automotive industry. As compared with the PE, one half of the synthetic raw materials of the PVC are from petroleum, and the other half are from rich minerals. But the recovering difficulty of the PVC and the potential influence to the environment are not solved, so that the limitations to the PVC in many occasions still exist. Therefore, the attention is necessary to be paid to the application, development and recycling problem of the PVC. The waste polyvinyl chloride recycled material can overcome the original defects of the polyvinyl chloride material, and has very important significance on the application and further promotion of the polyvinyl chloride material.
