Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial PVC pipe and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of living standards, people have higher and higher requirements for the comfort of the living environment, and their understanding of improving their own physical health is getting deeper and deeper. The domestic drainage system is not only able to meet people's needs by completing the drainage and sewage function, that is to say, the residents have put forward higher requirements for the function of the drainage pipe. Drainage pipe is an indispensable material in the household drainage system. The performance of this material directly determines the working stability and service life of the household drainage system. Therefore, it is imperative to develop pipes with excellent performance. [0003] Antibacterial property is an impo...
