Problems solved by technology

[0002] Latex paint has the characteristics of convenient construction and various colors. It occupies a dominant position in domestic interior wall decoration. However, conventional latex paint has no antibacterial effect. In hospitals, children or classroom rooms, bacteria are easily adsorbed on the wall, and people are not careful. It is easy to be contaminated with bacteria when in contact with the wall, which will cause harm to the body
At present, the common antibacterial latex paints on the market generally use organic antibacterial agent CMIT / MIT / organic bromine compound, or inorganic silver ion antibacterial agent, organic antibacterial agent CMIT / MIT / organic bromine compound is sensitive to pH, adding Large amount, relatively high toxicity, irritating to humans and animals

Abstract

The invention belongs to the field of a wall coating for indoor decoration, and particularly relates to an antibacterial latex paint. The antibacterial latex paint is characterized by being prepared from the following raw materials in parts by mass: 150-350 parts of water-based acrylic acid, 1-5 parts of defoaming agents, 2-4 parts of preservative agents, 5-10 parts of dispersing agents, 150-300 parts of pigments, 150-350 parts of fillers, 2-9 parts of thickening agents, 1-10 parts of levelling agents, 6-15 parts of nanometer inorganic negative ion antibacterial agents, 50-90 parts of nanometer polymer hollow microspheres, 50-90 parts of bamboo vinegar, 1-5 parts of cosolvents, 10-20 parts of citronella oil and 100-350 parts of water. The antibacterial latex paint disclosed by the invention can be coated on a wall and a wood. A paint film has the advantages of mild smell, good water solubility, low VOC, good covering power, low cost and optimal environment-friendly property. The antibacterial latex paint disclosed by the invention is a product which perfectly combines three themes, namely decoration, functionality and environmental friendliness, and has long-term continuous bacteriostatic effect.
