Abstract

The invention discloses a bacteriostatic coating and a preparation method thereof, and belongs to the coating field; the bacteriostatic coating comprises the following components by weight: 25-45 parts of a polyacrylate emulsion, 15-20 parts of a polyurethane emulsion, 6-15 parts of nano alumina, 5-10 parts of a talcum powder, 5-10 parts of a dispersing agent, 5-10 parts of an adsorbent, 7-15 parts of a curing agent, 2-15 parts of chitin, 4-10 parts of a thixotropic agent, 3-8 parts of a thickening agent, 2-8 parts of a defoaming agent, and 22-25 parts of deionized water. The bacteriostatic coating has the achieved beneficial effects that the formaldehyde release amount of the bacteriostatic coating is 0 g / L, a TVOC value is 0 g / L, and the coating also has waterproof and bacteriostatic effects, the application range is wider, and a coating film has better comprehensive performance.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an antibacterial coating and a preparation method thereof. Background technique [0002] Steel is an important engineering and structural material, but due to corrosion, its service life is greatly shortened or its use value is lost. According to statistics, the amount of corroded and scrapped steel accounts for more than 20% of the total amount of steel every year, and the loss of corroded steel in my country accounts for about 4% of the national economic output. In order to prevent steel corrosion, the simplest and most effective way is to use paint to protect. The annual demand for industrial coatings in my country is about 2.2 million tons, and 800,000 tons of organic solvents are volatilized every year. The waste of resources is about 3 billion yuan, and it also brings serious environmental pollution. As people's awareness of environmental protection increases, there is...
