Description

technical field

[0001] The invention relates to the technical field of polyvinyl chloride materials, in particular to an impact-resistant modified polyvinyl chloride composite material. Background technique

[0002] Polyvinyl chloride (PVC) is a thermoplastic high polymer produced by polymerization of vinyl chloride monomer. Because of its excellent flame retardancy, abrasion resistance, chemical corrosion resistance, comprehensive mechanical and physical properties, product transparency, It has the advantages of electrical insulation, low price, and convenient processing and installation. It has become one of the five general-purpose synthetic resins in the world. It has been widely used in the production of products with different characteristics, such as pipes, doors and windows, etc. But the impact performance of polyvinyl chloride is poor, which limits the application of polyvinyl chloride to a large extent. Although the addition of toughening agent modified polyvinyl ...
