Abstract

The invention relates to an environment-friendly heat-resistant high-toughness PVC transparent granular material, and preparation and application thereof. The granular material is prepared from, by weight, 90-120 parts of PVC resin, 15-30 parts of modified filled butadiene styrene rubber, 0.2-0.5 parts of an anti-aging agent, 2-4 parts of a thermal stabilizer, 0.8-1.2 parts of organic silicon modified plant oil, 1-4 parts of oxidized polyethlene wax, and 1-3 parts of phytosterol rice bran oleate. The granular material can be used for producing electrical tubular parts. Compared with the priorart, an electrical tube prepared from the PVC transparent granular material has great transparency with light transmittance reaching 92.4%; the material is excellent in compressive property, processability and anti-aging performance, can effectively overcome defects that a PVC composition tube material is liable to be aged and is poor in appearance. The material can improve anti-aging performanceand appearance and prolong the service life of the tube material, broadens application range of products, satisfies market demands, and has excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an environmentally friendly heat-resistant high-toughness PVC transparent pellet and its preparation and application. Background technique [0002] PVC is the abbreviation of Polyvinylchlorid, the main component is polyvinyl chloride, and polyvinyl chloride is a kind of strong polar polymer, there is a great force between molecules, it needs to be heated to a certain temperature to show its plasticity, so it needs to be added Other ingredients to enhance its heat resistance, toughness, ductility. PVC is sensitive to heat. When it is heated to 130-140°C, it will start to decompose seriously, and it will turn brown or black and cannot be processed, and will release HCl gas. If the generation of HCl gas is not suppressed, it will further decompose. Intensified and accelerated. The current general method is to add heat stabilizers to PVC resin to effectively suppress or del...
