Abstract
The present invention provides an antibacterial powder coating, a preparation method and application thereof, which comprise component A, component B and component C, wherein organic antibacterial agent, zinc ion antibacterial agent and silver ion antibacterial agent are compounded in component A In combination with texture agent, surface roughening agent, and the synergistic effect of component B, a broad-spectrum antibacterial powder coating can be prepared, which can be used in floors, railings, home furnishing, furniture, home appliances, curtain walls, and medical equipment. In the surface treatment process, under the curing conditions of 160‑180℃ / 10‑15min, the microscopic surface roughness and crosslinking density of the coating film can be improved, the wear resistance of the coating film, and a longer antibacterial period can be obtained. The invention solves the problems of poor antibacterial effect and short antibacterial effect of coatings in the prior art.
Description
technical field [0001] The invention relates to the field of powder coating preparation, in particular to an antibacterial powder coating and its preparation method and application. Background technique [0002] The powder coating of the prior art is in an environment where the climate is humid and the temperature is suitable for the growth of other harmful microorganisms such as bacteria or mold. To protect the decorative function, the most important thing is that if harmful fungi grow and multiply on the coating film, it will also affect people's health. In addition, the powder coating in the prior art increases the antibacterial effect of the powder coating by adding an antibacterial agent, but the antibacterial agent has the problems of poor antibacterial effect and short antibacterial time limit, and when the antibacterial powder coating is applied, it will also be due to the interaction between the components. Poor tolerance leads to poor film-forming effect; the appl...
