Problems solved by technology

However, the C-Cl bond in the polyvinyl chloride molecule is easy to remove the HCl molecule when heated, and unsaturated bonds are introduced into the macromolecular chain, which affects the aging resistance and thermal stability of the resin, thus limiting the use of polyvinyl chloride. and use space
With the development of society, people have put forward higher requirements for material performance. The wear resistance and heat resistance of current polyvinyl chloride materials cannot meet the requirements of society, and further research and modification are needed.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a wear-resistant and heat-resistant modified polyvinyl chloride composite material. Background technique [0002] Polyvinyl chloride is one of the earliest industrialized plastic varieties in the world. It is a general-purpose resin with excellent performance and low price. It has excellent flame retardancy, corrosion resistance, wear resistance, small friction coefficient, low thermal conductivity, and sealing performance. Good, dustproof, sound insulation, earthquake resistance, weather resistance and other advantages, it has a wide range of applications in construction, light industry, agriculture, packaging, daily use and other fields. However, the C-Cl bond in the polyvinyl chloride molecule is easy to remove the HCl molecule when heated, and unsaturated bonds are introduced into the macromolecular chain, which affects the aging resistance and thermal stability of the resi...
