Problems solved by technology

However, the antibacterial powder coatings that appear on the existing market simply adopt metal ion additives and silver additives to achieve a single antibacterial function.
However, the defect of this type of antibacterial coating is that the antibacterial effect will decline with the passage of time, and finally the antibacterial ability designed at the beginning cannot be achieved, and the additives used will pollute and damage the environment to a certain extent, and can only achieve a single antibacterial function. defect

Abstract

The invention relates to an environmentally-friendly antibacterial powder coating, belonging to the technical field of coating material and aiming to solve the technical problems that the antibacterial function of the coating in the prior art is single and the antibacterial capacity ceases to be effective quickly. The environmentally-friendly antibacterial powder coating mainly comprises the following raw materials by weight: 30-40% of polyester, 30-40% of epoxy resin, 0.5-1.5% of a leveling agent, 0.5-1.5% of a brightening agent, 8.0-16% of an anion generating agent, 8.0-12% of a coupling agent, 2.0-4.0% of an antibacterial agent and 3.0-6.0% of a cross-linking agent. The coating can generate anions of about 1,000/cm<3> and has a good antimicrobial effect, the antibacterial rate of more than 95% and the multiple effects of causing less pollution to the environment.

Description

technical field [0001] The invention relates to a paint, in particular to an environment-friendly and antibacterial powder paint, which belongs to the technical field of paint materials. 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] Simultaneously, along with the improvement of people's requirements for fu...
