Abstract

The invention relates to a composite flame-retardant and antimicrobial PVC-U (unplasticised polyvinyl chloride) pipe and a preparation method thereof. The composite flame-retardant and antimicrobial PVC-U pipe comprises the following materials by weight percent: 0.1-1% of functional masterbatch, and the balance of PVC-U masterbatch. The preparation method comprises the following concrete step of extruding the PVC-U pipe obtained in a molding process; the color of the color masterbatch can be converted according to the actual needs. The PVC-U pipe disclosed by the invention is nontoxic and sanitary, convenient to install, and good in chemical resistance, and especially has good thermal welding performance; molecules are completely fused together at the joint; the problem of water leakage at the joint of the pipelines of puzzling the water supply industry for a long period of time is solved.

Description

【Technical field】 [0001] The invention relates to the technical field of functional materials, in particular to a composite flame-retardant and antibacterial PVC-U pipe and a preparation method thereof. 【Background technique】 [0002] With the rapid development of industry and the improvement of people's living standards, especially the awareness of health is also increasing. Because harmful bacteria are widely distributed in nature, and there are various types and large numbers, they seriously threaten human health. Diseases caused by bacterial transmission and infection have become a major social problem and have attracted widespread attention. Therefore, research on disinfectants is particularly important. Guanidine disinfectant is a type of disinfectant and antibacterial agent that has been widely used in recent years. It is easy to use and has a wide antibacterial spectrum, low toxicity, and no irritation. , It can also be used for the disinfection of fiber paper, fo...
