Novel plastic formula for hard PVC board

Abstract

The invention discloses a novel plastic formula for a hard PVC board. The hard PVC board is prepared from, by weight, 60-70 parts of nylon, 15-20 parts of PVC, 14-20 parts of fine corundum powder, 9-13 parts of melamine cyanurate, 23-29 parts of glass fibers, 25-35 parts of octyltin mercaptide, 18-28 parts of silicon carbide powder, 14-20 parts of sodium carboxymethylcellulose, 3-6 parts of potassium nitrate, 3-7 parts of sepiolite, 9-17 parts of sodium salicylate, 3-8 parts of titanium dioxide, 10-20 parts of asbestos powder, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of ramie sticks, 13-15 parts of acetyl tributyl citrate, 2-3 parts of diethylene glycol monoethyl ether acetate, 3-4 parts of sodium oxide, 0.2-0.4 part of nano-aluminum oxide, 0.2-0.4 part of palladium nitrate, 0.2-0.4 part of nano-zirconia, 0.2-0.4 part of nano-cerium oxide, 0.2-0.4 part of nano-neodymium oxide and 0.2-0.4 part of nano-yttria. According to the formula, the application temperature of the hard PVC board is raised, machining performance is optimized, high-speed machining of the PVC board is promoted, and machining efficiency of products is improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a novel plastic formula for rigid PVC boards. Background technique [0002] Polyvinyl chloride (PVC) extruded sheet has good acid resistance and corrosion resistance, and is widely used in chemical production and chemical anticorrosion process. However, the heat resistance of polyvinyl chloride is limited, so that it cannot be used in a working environment above 65°C for a long time, thus limiting the application range of polyvinyl chloride sheets. [0003] In the prior art, various heat-resistant modifiers are added to the polyvinyl chloride sheet to increase the heat-resistant temperature of the polyvinyl chloride sheet. Although the heat-resistant modification effect is obvious, it has high processing cost and is not easy to process. and other practical issues. Contents of the invention [0004] The purpose of the present invention is to provide a novel hard PVC sheet pl...
