Abstract

The invention discloses a wooden product antibacterial finishing paint, relating to the technical field of coatings. The wooden product antibacterial finishing paint comprises the following components in parts by weight: 70-85 parts of water-soluble polyurethane emulsion, 8-12 parts of water-soluble amine resin, 0.05-0.1 part of nano silicon dioxide, 0.05-0.1 part of nano titanium dioxide, 0.1-1 part of a fluorocarbon modified acrylate leveling agent, 30-45 parts of hexamethylene diisocyanate, 5-8 parts of ethanol, 15-20 parts of a pigment, 2-5 parts of bentonite, 8-10 parts of silicon dioxide, 1-3 parts of silicone oil and 5-10 parts of water. Compared with an existing wood-ware finishing paint, the wooden product antibacterial finishing paint disclosed by the invention has a significant antibacterial effect, and the antibacterial rate can reach 100%.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an antibacterial finish paint for wood products. Background technique [0002] Affected by the rainy and humid weather in the south, the surface of many wooden furniture is prone to breed bacteria such as Escherichia coli and Staphylococcus aureus, which makes the surface of the furniture moldy and discolored, which not only affects the appearance of the furniture, but also causes bacteria to reproduce and spread diseases. At present, most of the traditional wood paints are solvent-based wood paints, mainly solvent-based polyurethane and nitro-based paints. Due to the high total amount of organic volatiles, this wood paint pollutes the environment and affects people's health. Therefore, it is consumed The volume is declining year by year, while water-based wood lacquers do not pollute the environment and have a good market prospect. However, most of these water-based wood paint...
