Abstract

The invention relates to a polyvinyl chloride modified plastic which comprises 70-85 parts of polyvinyl chloride, 3-6 parts of ethylene-vinyl acetate (EVA) resin, 3-8 parts of acrylonitrile butadiene styrene (ABS) resin, 2-5 parts of polystyrene, 3-5 parts of low density polyethylene, 5-10 parts of chlorinated polyvinyl chloride and 0.5-2 parts of titanium dioxide. The impact resistance, cold resistance and processability of the polyvinyl chloride are improved.

Description

Technical field [0001] The invention belongs to the field of plastics, and specifically relates to a polyvinyl chloride modified plastic. Background technique [0002] Polyvinyl chloride, abbreviated as PVC in English (Polyvinylchloridepolymer=PVC molecular structure), is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC is a white powder with an amorphous structure with a small degree of branching. However, polyvinyl chloride has poor cold resistance and processing properties. Summary of the invention [0003] The purpose of the present invention is to provide a modified polyvinyl chloride plastic, which improves the cold resistance, radiation protection and impact properties of polyvinyl chloride. [0004] The present invention is realized through the following technical solutions: [0005] A...
