Problems solved by technology

The existing production of PVC pipes is mainly through the addition of chlorinated polyethylene as an auxiliary agent, which can easily lead to low output of PVC pipes
[0003] However, rigid polyvinyl chloride (PVC-U) pipes are relatively brittle, especially at low temperatures, have low impact strength, and poor crack resistance, which brings more problems and inconvenience to installation and use.

Abstract

The invention relates to a high-impact-resistance polyvinyl chloride pipe material, and relates to the technical field of plastic processing. The pipe material is composed of the raw materials of, by weight, 80 parts of polyvinyl chloride resin, 5-10 parts of an impact modifier, 5-10 parts of phosphite, 0.5-5 parts of a stabilizer, 2-5 parts of a lubricant, 1-5 parts of light carbon carbonate, and 1-2 parts of a brightening agent. The system satisfies a condition to make rigid organic particles yield, such that a synergistic effect is provided. Also, PMMA is a polymer with relatively high rigidity and high strength. With the addition of PMMA, certain contribution is made to the strength of the material.

Description

technical field [0001] The invention relates to a polyvinyl chloride pipe material with high impact resistance, belonging to the technical field of plastic processing. Background technique [0002] PVC pipe is a commonly used plastic pipe at present, which has the advantages of light weight, corrosion resistance, high strength, good weather resistance and flame retardancy, and low price. The existing production of PVC pipes is mainly through the addition of chlorinated polyethylene as an auxiliary agent. Such a production method will easily lead to a low output of PVC pipes. [0003] However, rigid polyvinyl chloride (PVC-U) pipes are relatively brittle, especially at low temperatures, have low impact strength, and poor crack resistance, which brings many problems and inconvenience to installation and use. [0004] Therefore, we need a high-impact PVC pipe, which can not only maintain the elastic modulus of the pipe, but also improve the flexibility of the pipe, which great...
