Abstract

The invention relates to a long-lasting antibacterial PVC water supply pipe and a preparation method thereof. The preparation method includes antibacterial agent discoloration treatment, antibacterial agent microcapsule preparation, antibacterial agent microcapsule surface modification, long-lasting antibacterial PVC water supply pipe preparation and other steps. The long-lasting antibacterial PVC water supply pipe of the present invention has an antibacterial rate of more than 99% against Escherichia coli and Staphylococcus aureus after being soaked in a distilled water bath with a temperature of (50±2)°C for 16 hours; its physical and mechanical properties are similar to ordinary PVC water supply pipes of the same specification, and it is safe and hygienic. Excellent performance. In particular, the outstanding long-lasting antibacterial performance solves the technical problem of the current antibacterial water supply pipes’ antibacterial performance declining or even completely losing during actual use, and at the same time, the dissolution of antibacterial ingredients affects the health and safety of the water supply. Therefore, it can be widely used in various water supply pipe network systems that are closely related to people's production and life.

Description

【Technical field】 [0001] The invention belongs to the technical field of plastic pipes. More specifically, the present invention relates to a PVC water supply pipe with long-term antibacterial function, and also relates to a preparation method of the PVC water supply pipe with long-term antibacterial function. 【Background technique】 [0002] Water is the source of life, and human production and life cannot be separated from water for a moment. The health and safety of drinking water is the focus of attention. The water from the water plant is distributed to thousands of households through the water supply network. The water after disinfection treatment by the waterworks often carries a small amount of microorganisms and organic matter. In the process of flowing through the water supply pipe network, the organic matter is not only the nutrition of microorganisms, but also the substance that promotes the formation of biofilm on the inner wall of the pipe network. As ordinar...
