Example Embodiment

[0024] Example 1:

[0025] A method for preparing high-gloss decorative two-component acrylic polyurethane antibacterial (varnish or silver paint). Take 80 parts of hydroxy acrylic resin, 4 parts of butyl acetate, 2 parts of xylene, 0.7 parts of leveling agent in proportion, add 3 parts of pretreated inorganic antibacterial agent, mix and stir evenly, and then adjust the viscosity with butyl acetate until the viscosity is qualified Prepare antibacterial varnish, or put in metallic glitter powder (pearl powder), the amount is 5%, stir evenly to prepare antibacterial glitter paint (silver paint), after confirming the color, perform performance inspection, packaging, and then perform antibacterial and heavy metal Content detection, that is, this product is obtained.

Example Embodiment

[0026] Example 2:

[0027] A method for preparing high-gloss decorative two-component acrylic polyurethane antibacterial (color paint). Take 40 parts of hydroxy acrylic resin, 8 parts of pigment, 4 parts of butyl acetate, 2 parts of xylene, 0.5 part of dispersant, mix and stir uniformly, pre-disperse, grind, and control the fineness. After the fineness is qualified, Add 35 parts of hydroxy acrylic resin and 0.3 parts of leveling agent. Stir until uniform. Pay attention to control the viscosity during the stirring process to obtain semi-finished color paste. To color the semi-finished color paste, add 3 parts of pretreated inorganic antibacterial agent. Adjust with butyl acetate until the viscosity is qualified, then stir evenly, after confirming the color, perform performance inspection, packaging, and finally perform antibacterial and heavy metal content detection to obtain the antibacterial paint finished product.

Abstract

The invention provides a high glaze ornamental and double-component acrylic polyurethane anti-bacterium coating which contains the following components: 60 percent-80 percent of hydroxylated acrylic resin, 1 percent-10 percent of pigment, 3 percent to 5 percent of butyl acetate, 1 percent to 3 percent of dimethylbenzene, 0.5 percent to 1 percent of accessory ingredient and 1 percent to 5 percent of inorganic antiseptics. The anti-bacterium coating also contains curing agent, and the proportion of the anti-bacterium to the curing agent is 3 to 6: 1. The pigment can also adopt metallic flakes or pearls powder; the accessory ingredient is a flatting agent or a dispersant; the curing agent is urethane resin of fatty group. The novel anti-bacterium coating combines the functions of environmental protection, high decorativeness and protection and antibacterial property, and can be taken as the protective coating of electronic products, household appliances, sanitary wares and public facilities.

Description

Technical field [0001] The invention relates to a high-gloss decorative two-component acrylic polyurethane antibacterial paint, which belongs to the field of chemical coatings. Background technique [0002] With the development of society, the improvement of living standards and the enhancement of environmental protection awareness, people are paying more and more attention to the impact of daily necessities on their own health. Contaminants such as bacteria and molds breed on the surface of many daily necessities, which will affect the use and contact. People who produce products pose a health threat, even life-threatening. Therefore, most of the living appliances, common household appliances, interior parts of public transportation, and sanitary ware, etc., are required to have high decorative properties and antibacterial properties. [0003] At present, most of the antibacterial and antifungal coatings are water-based paints. They are used for internal and external walls, and ...
