[0002] Due to the inherent molecular structure characteristics of polyvinyl chloride (PVC), when directly used as raw material to produce plastic products by extrusion, its chemical properties have many defects, especially poor light and heat stability. Without heating stabilizer, polyvinyl chloride begins to decompose at 100℃, releases toxic hydrogen chloride gas upon heating, discolors, and undergoes photo-oxidative decomposition in ultraviolet light and oxygen, resulting in decreased flexibility and brittleness. Obviously, it cannot meet the requirements of polyvinyl chloride products in daily life and industry. Therefore, during the production process of polyvinyl chloride material forming and processing, a certain amount of PVC lubricant is usually added to the polyvinyl chloride resin powder to change the chemical properties of the polyvinyl chloride material.
