Abstract

The invention discloses an antibacterial sublimation transfer-printing wood-grain powder coating composition. The coating composition is prepared by carrying out dry mixing on base powder and a bonding coating antibacterial agent according to the following ratio: 95%-97% of the base powder and 3%-5% of the bonding coating antibacterial agent. According to the invention, bonding and coating are carried out on organic silicon resin with inorganic and organic antibacterial agents, bonding and processing are carried out by using a bonding machine, and then dry mixing is carried out with bottom powder to obtain the antibacterial sublimation transfer-printing wood-grain powder coating composition. A coating layer obtained after curing and transferring of the antibacterial sublimation transfer-printing wood-grain powder coating has a fast-acting property of the organic antibacterial agent and heat resistance and light resistance of the inorganic antibacterial agent, and has the antibacterialeffect of broad spectrum, safety and difficult generation of drug resistance of bacteria.

Description

technical field [0001] The invention belongs to the field of powder coating preparation and relates to an antibacterial sublimation transfer wood grain powder coating composition. Background technique [0002] The antibacterial function of coatings is mainly realized by adding antibacterial agents to coatings. The antibacterial agents popular in the current market include three categories: natural antibacterial agents, organic antibacterial agents and inorganic antibacterial agents. [0003] Natural antibacterial agents have poor thermal stability and large additions, which limit their application in powder coatings; organic antibacterial agents are dissolution-type and active antibacterial. Its mechanism of action is to destroy the cell membrane, acidify -SH, cause protein denaturation, block metabolism, and kill bacteria quickly. It has been used for more than 30 years, and the dosage is small. However, the heat resistance and light resistance are poor, and the action l...
