A kind of PVC water supply pipe with long-acting antibacterial function and preparation method thereof

Abstract

The invention relates to a PVC (Polyvinyl Chloride) water feeding pipe with a long-acting antibacterial function and a preparation method thereof. The preparation method comprises the following steps: carrying out anti-staining treatment on an antibacterial agent, preparing an antibacterial agent microcapsule, carrying out surface modification on the antibacterial agent microcapsule, preparing a long-acting antibacterial PVC water feeding pipe and the like. After the long-acting antibacterial PVC water feeding pipe provided by the invention is immersed with a distilled-water water bath at a temperature (50+ / -2 DEG C) for 16h, the antibacterial rate on escherichia coli and staphylococcus aureus is more than 99%; physical-mechanical properties are similar with those of a common PVC water feeding pipe with the same specification; and the safety and sanitary performances are excellent. Especially, the long-acting antibacterial PVC water feeding pipe has the prominent long-acting antibacterial performance so that the technical difficulties that the antibacterial performance is reduced, even completely lost in an actual utilization process of the current antibacterial water feeding pipe, and antibacterial components are dissolved out to influence sanitation and safety of water supply quality are solved. Therefore, the PVC water feeding pipe can be widely applied to various water supply pipe network systems which are tightly related to production and living of people.

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...
