Problems solved by technology

[0005] Existing PVC water supply pipes generally have a single-layer structure, and most of them are white, and the shading effect is not good. If they are used outdoors for a long time, they will provide a good environment for the growth of bacteria, which often leads to the inside of the pipe body. Breed a large number of bacteria, which brings great hidden dangers to the life and health of users
In addition, in the case of overcooling and overheating, it is easy to deform or even crack, which affects the use effect

Description

technical field [0001] The invention relates to the technical field of water supply pipes, in particular, it provides an aging-resistant and antibacterial PVC water supply pipe and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to health problems, but with the deterioration of the environment, diseases caused by various bacteria are becoming more and more frequent, among which water is closely related to people's life, and the content of bacteria in water directly determines the quality of the water. [0003] As early as the 1950s, PVC (polyvinyl chloride) pipes were researched and developed abroad, and PVC water supply pipes were widely used in indoor and outdoor water supply pipes. Since 1960, my country has begun to use PVC water supply pipes in water supply projects. PVC water supply pipes have excellent physical properties, good corrosion resistance, chemical stability and flame r...
