Embodiment 1

[0016] The antibacterial topcoat of this wood product uses the following raw materials:

[0017] 40 parts of acrylic emulsion; 10 parts of modified rosin resin; 0.1 part of nano zinc oxide; 0.1 part of fluorocarbon modified acrylate leveling agent; 30 parts of hexamethylene diisocyanate; 2 parts of ethanol; 5 parts of pigment; 8 parts of silicon; 1 part of mineral oil; 5 parts of deionized water;

[0018] Its preparation method comprises the following steps:

[0019] A, the above-mentioned hexamethylene diisocyanate and ethanol are put into the reactor and mixed, and react until the NCO value is less than 0.5;

[0020] B. Put nano zinc oxide, fluorocarbon modified acrylate leveling agent, pigment, bentonite, silicon dioxide, water and the product of step A into a grinder, and grind to a fineness of less than 10 microns;

[0021] C. Pour the result of step B into a high-speed disperser, add acrylic acid emulsion, modified rosin resin and mineral oil and disperse at a speed of...

Embodiment 2

[0024] The antibacterial topcoat of this wood product uses the following raw materials:

[0025] 60 parts of acrylic emulsion; 2 parts of modified rosin resin; 0.5 parts of nano zinc oxide; 1 part of fluorocarbon modified acrylate leveling agent; 20 parts of hexamethylene diisocyanate; 5 parts of ethanol; 10 parts of pigment; 10 parts of silicon; 3 parts of mineral oil; 10 parts of deionized water;

[0026] Its preparation method is identical with embodiment 1.

[0027] After testing, the antibacterial rate of the antibacterial topcoat for wood products prepared in this embodiment is 100%.

Abstract

The invention discloses an antibacterial finishing coat for wood products, relating to the technical field of coatings. The antibacterial finishing coat is prepared from the following components in parts by weight: 40-60 parts of an acrylic emulsion, 2-10 parts of modified rosin resin, 0.1-0.5 part of nano-zinc oxide, 0.1-1 part of fluorine-carbon-modified acrylate flatting agent, 20-30 parts of hexamethylene diisocyanate, 2-5 parts of ethanol, 5-10 parts of pigments, 2-5 parts of bentonite, 8-10 parts of silicon dioxide, 1-3 parts of mineral oil and 5-10 parts of deionized water. Compared with existing woodware finishing coats, the antibacterial finishing coat has the advantages that the antibacterial effect is obvious, and the antibacterial rate reaches 100%.

Description

technical field [0001] The invention relates 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...
