Abstract

The invention provides a high-gloss polyvinyl chloride resin composition as well as a preparation method and application thereof. The high-gloss polyvinyl chloride resin composition comprises the following components in parts by weight: 80-100 parts of polyvinyl chloride resin, 0.1-0.3 part of a release agent, 2-20 parts of an acrylonitrile-styrene copolymer, 10-30 parts of light calcium carbonate, 0.3-2 parts of a heat stabilizer, 4-8 parts of an impact modifier, 0.5-2 parts of a processing modifier, and 0.3-2.5 parts of a lubricant, wherein the release agent is oxidized high-density polyethylene wax. The polyvinyl chloride resin composition has relatively high glossiness and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of modification of functional plastics, in particular to a high-gloss polyvinyl chloride resin composition and its preparation method and application. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic made of vinyl chloride monomer (VCM) through free radical polymerization. It can be made into hard and soft products for different purposes by adding appropriate additives. PVC has unique properties such as high strength, corrosion resistance, flame retardant, insulation, transparency and good compatibility with a wide range of various plastic additives. Therefore, it is widely used in industry, agriculture, construction, daily necessities, packaging and other fields. The main products include pipe fittings, door and window profiles, plates and sheets, wire insulation, medical supplies, films, sealing strips, etc. [0003] Polyvinyl chloride wire trough widely used in the cons...
