Abstract

The invention discloses an acrylate antibacterial coating. The acrylate antibacterial coating is characterized in that the acrylate antibacterial coating includes the following components in parts by weight: 0.1 to 0.5 part of a disperser, 0.1 to 0.5 part of a pH modifier, 0.2 to 0.5 part of a defoamer, 0.8 to 2 parts of a coalescing agent, 2 to 3 parts of ethylene glycol, 2 to 5 parts of inorganic nano-materials, 0.5 to 2 parts of an antibacterial agent, 9 to 15 parts of titanium dioxide, 15 to 20 parts of calcium carbonate, 5 to 10 parts of talcum powders, 18 to 25 parts of styrene-acrylate emulsion, 18 to 25 parts of a thickener, and 20 to 40 parts of deionized water; preferably, the disperser is sodium hexametaphosphate. The inorganic nano-materials are used for modification of the antibacterial performance of coatings, that is, the materials are used for modification of an ordinary acrylate coating, so as to achieve the nano-modified coating; the acrylate antibacterial coating has the advantages of easy acquisition of the raw materials, environment friendliness, harmlessness to human bodies, good and lasting antibacterial effect and the like, and can effectively prevent the growth and reproduction of escherichia coli, staphylococcus aureus and other bacteria.

Description

technical field [0001] The invention relates to a coating, in particular to an acrylate antibacterial coating. Background technique [0002] With the development of society, people's daily life and many fields such as buildings, ships, and circulating cooling water have antibacterial needs. Therefore, the development of coatings with antibacterial function is one of the development directions of the coatings industry. Antibacterial coatings can be made by adding certain suitable and stable antibacterial materials to the coating. Antimicrobial coatings can be applied directly to various materials and are attracting attention for their ease of use. Keeping the environment clean and pollution-free is a practical and feasible way to prevent bacteria and viruses from multiplying and preventing them from infecting humans. Using antibacterial materials is the simplest and most effective way to achieve a clean and pollution-free environment. Traditional wall coatings have poor an...
