High-toughness polyvinyl chloride tubular product

Abstract

The invention discloses a high-toughness polyvinyl chloride pipe, the raw materials of which include by weight: 35-42 parts of polyvinyl chloride, 10-18 parts of polyurethane rubber, 20-30 parts of butyl rubber, and 20-30 parts of filling and reinforcing agent 1-2 parts of epoxidized soybean oil, 1-2 parts of magnesium stearate, 1-2 parts of triphenyl phosphate, 1.5-3 parts of compatibilizer, and 2-4 parts of crosslinking agent. The high-toughness polyvinyl chloride pipe provided by the invention has good toughness, high pressure resistance, high flexural strength, and excellent high-temperature stability.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride pipes, in particular to a high-toughness polyvinyl chloride pipe. Background technique [0002] PVC pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. As early as the 1950s, PVC pipes were researched and developed abroad, and PVC pipes were widely used in indoor and outdoor water supply pipes. Since 1960, my country has begun to use PVC pipes in water supply projects. PVC pipes have excellent physical properties, good corrosion resistance, chemical stability and flame resistance, and are low in price. However, the toughness of PVC pipes is poor, and the material is prone to cracking after impact, and its compressive strength and high temperature stability are poor. Contents of the invention [0003] Based on the technical problems in the background technology, ...
