Problems solved by technology

[0003] At present, the working environment of various pipelines is becoming more and more complicated. In basements, seaports, well bottoms, deep water, tunnels, chemical plants, etc., traditional polyethylene resin powder or epoxy resin powder coating on the surface of the pipeline only has A certain anti-corrosion function has no effect on the growth and reproduction of microorganisms such as bacteria on the coating surface. When the coating is used for the surface coating of pipes storing or transporting health and hygiene products, it only plays a general anti-corrosion function. The secondary pollution caused by intrusion has no effect

Abstract

The invention discloses an antibacterial powder coating for pipeline. The antibacterial powder coating comprises the following raw materials in parts by weight: 60-90 parts of resin powder, 20-30 parts of filler, 0.5-1.5 parts of tetramethyl ammonium iodide, 3-5 parts of enhancer, 2-4 parts of corrosion inhibitor, 1-8 parts of antibacterial agent and 0.2-0.7 parts of paint. The proportion of each raw material of the antibacterial powder coating for pipeline is reasonable, the corrosion resistance of the material is enhanced, and the antibacterial powder coating has excellent inhibiting and killing effects on microorganisms like fungi, bacteria and mould, is healthy and environment-friendly, and is especially applicable to pipelines for storing and transporting healthy and clean products; after being sprayed with the paint, the surface gloss is good and products are attractive and practical; the preparation method is convenient, the materials are easy to get, the process is simple, the production cost is saved, the effect is significant, and so the antibacterial powder coating has wide application prospect.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an antibacterial powder coating for pipelines. Background technique [0002] With the increasing variety of coating products and the continuous expansion of the application range, the coating industry has become an important independent industrial production part of the chemical industry. And in the coatings industry, powder coatings belong to the fastest growing category. However, in order to reduce the pollution to the atmosphere, environmental protection laws and regulations are increasingly strict on the control of pollution sources, requiring the development of pollution-free and resource-saving coating varieties. Therefore, solvent-free, protective and decorative powder coatings have developed rapidly because of their economic and social benefits. [0003] At present, the working environment of various pipelines is becoming more and more complicated. In basements, seaports, well b...
