Novel formaldehyde removal anti-microbial water-based UV paint

Abstract

The invention discloses a novel formaldehyde-removing antibacterial water-based UV paint and a preparation method thereof. The paint is composed of raw materials with the following mass components: 30-60 parts of water-based UV polyurethane acrylate emulsion, 5-10 parts of water-based wetting and dispersing agent, 0.3-0.5 parts of water-based defoamer, 5-10 parts of co-solvent, 1.5-2.5 parts of water-based photoinitiator, 0.3-0.5 parts of amine neutralizer, 15-20 parts of deionized water, 2-3 parts of water-based thickener , 10-40 parts of nano-silica powder, 0.5-1 part of chitosan; the present invention has the functions of improving environmental protection performance of the coating, antibacterial, formaldehyde removal, air purification, enhanced coating resistance to scratching, high-efficiency utilization, energy saving, green environmental protection, The advantages of mechanical coating operation and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a formaldehyde-removing and antibacterial water-based UV paint. Background technique [0002] Furniture panels contain a large amount of formaldehyde released into the air. Formaldehyde is a carcinogen that can cause serious harm to people living in such an environment. The paints used in the furniture industry for a long time are mainly traditional solvent-based paints. When the furniture made of boards is sprayed, a large amount of formaldehyde will be produced; and traditional solvent-based colorants are sprayed, which is inefficient, high in cost, pollutes the environment, and affects the health of construction workers; the raw materials for making solvent-based paints contain a large amount of Flammable organic volatile solvents such as toluene, acetone, ethyl acetate curing agent and other flammable and explosive dangerous goods, the products of solvent-based coatings afte...

[0002] Furniture panels contain a large amount of formaldehyde released into the air. Formaldehyde is a carcinogen that can cause serious harm to people living in such an environment. The paints used in the furniture industry for a long time are mainly traditional solvent-based paints. When the furniture made of boards is sprayed, a large amount of formaldehyde will be produced; and traditional solvent-based colorants are sprayed, which is inefficient, high in cost, pollutes the environment, and affects the health of construction workers; the raw materials for making solvent-based paints contain a large amount of Flammable organic volatile solvents such as toluene, acetone, ethyl acetate curing agent and other flammable and explosive dangerous goods, the products of solvent-based coatings after film formation do not have fire-proof and flame-retardant effects, and they are easy to burn when encountering sparks, causing fire hazards

[0003] Water-based UV paint is loved by people because it does not contain organic solvents, no VOC volatilization, and will not cause harm to the air and operators. However, the technical content of water-based UV paint is relatively high, and production is difficult. The effect is slightly worse than that of PU topcoat products;
