Problems solved by technology

However, 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 chloride can improve the impact performance of polyvinyl chloride material, but the addition of too much toughening agent will increase the melt viscosity of polyvinyl chloride, thus making the processing of polyvinyl chloride difficult and causing consumption Can improve and product deterioration
In the current modification method, it is difficult to achieve a balance between impact resistance and processability

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 ...
