Wear-resistant modified PVC (polyvinyl chloride) material and synthesis process

The invention relates to the technical field of PVC (polyvinyl chloride), and discloses a wear-resistant modified PVC material, a hyperbranched polymer is grafted on the surface of a carbon nanotube, a molecular main chain contains a rigid imide structure of a polyamide structure, meanwhile, the tail end contains rich maleimide groups, and under the initiation of dicumyl peroxide, graft polymerization with polyvinyl chloride is carried out, so that the wear-resistant modified PVC material is obtained. The hyperbranched polymer modified carbon nanotube is grafted into the polyvinyl chloride, and the interfacial strength and intermolecular force between the hyperbranched polymer modified carbon nanotube and the polyvinyl chloride are enhanced, so that the dispersity of the carbon nanotube is improved, and the agglomeration is overcome; the hyperbranched polymer modified carbon nanotubes and polyvinyl chloride form a chemical crosslinking and chain entanglement network, so that the effects of dispersing stress a
