Problems solved by technology

[0003] At present, problems such as odor and mildew are commonly used in household drainage outlets on the market. Ordinary antibacterial coatings are difficult to process through the double-layer co-extrusion process due to their poor adhesion. Even if the antibacterial coating is processed, the processed The product is also easy to delaminate and cause failure

Abstract

The invention relates to the technical field of novel materials and in particular relates to an antibacterial anti-mold water drainage PVC (Polyvinyl Chloride) tube and a production method thereof. The antibacterial anti-mold water drainage PVC tube comprises an antibacterial anti-mold layer as an inner layer and a PVC composite material layer as an outer layer, wherein the antibacterial anti-moldlayer is made of a nano metal ion / PVC composite material and comprises the following components in parts by weight: 100 parts of PVC, 0.5-2 parts of nano metal ions, 3.5-5.5 parts of a stabilizer, 8-12 parts of chlorinated polyethylene, 0.5-1.5 parts of stearic acid, 1-3 parts of lead stearate, 0.2-0.8 part of polyethylene wax, 0.5-2 parts of processing aids, 0.5-1 part of a composite coupling agent, 1-5 parts of a macromolecule load and 0.5-4 parts of a macromolecule compatilizer. The production method comprises the following steps: mixing raw materials of the antibacterial anti-mold layer,mixing materials of the PVC composite material layer, and preparing the double-layer antibacterial anti-mold water drainage PVC tube. The antibacterial anti-mold water drainage PVC tube has a very good growth inhibition function on aspergillus niger, aureobasidium pullulans, penicillium funiculosum chaetomium globosum, gliocladium viride and the like, is simple in process, low in manufacturing cost, long-lasting and stable in effect and applicable to industrial popularization and production.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an antibacterial and mildew-proof drainage PVC pipe and a production method thereof. Background technique [0002] With the progress of society, people have higher and higher requirements for the comfort of living environment. 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. [0003] At present, problems such as odor and mildew are commonly used in household drainage outlets on the market. Ordinary antibacterial coatings are difficult to process through the double-layer co-extrusion process due to their poor adhesion. Even if the antibacterial coating is processed, the processed The product is also prone to delamination causing failure. [0004] In view of this, in order to provide a more comfortable ...
