Preparation method of negative ion coating with virus and bacterium removing function

Abstract

The invention discloses a preparation method of a negative ion coating with a virus and bacterium removing function. The preparation method comprises the following steps: weighing required raw materials according to a formula of the negative ion coating; crushing, grinding and ball-milling the weighed calcium carbonate powder, volcanic rock powder, negative ion powder, diatomite powder, sulfur powder, quartz powder, glutinous rice flour, titanium dioxide and bamboo charcoal powder; putting the superfine powder A into a closed stirring kettle for stirring operation; putting the mixture B, deionized water, an antibacterial agent, an anti-corrosion and anti-mildew agent, a dispersing agent, a compatilizer, an anti-freezing agent, a leveling agent and a cosolvent into a closed mixing machine for mixing operation; adding the weighed glycerol, plant essential oil, defoaming agent and thickening agent, and continuously mixing. Compared with the prior art, the negative ion coating has excellent antibacterial and bactericidal properties, is beneficial to removing viruses and bacteria, has the advantages of no toxicity, no harm, strong adhesion and uniform mixing of raw materials, has excellent use effect, simple preparation process and high production efficiency, and lowers the production cost.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a method for preparing an anion paint with the function of eliminating viruses and bacteria. Background technique [0002] Coatings are mainly used for whitewashing walls, and the susceptibility of coatings to microbial attack depends on the chemical properties of coatings and solvents, the types of surface coverings and the exposure conditions of coating films; currently the coating products on the market are mainly made of chemical substances , not only will release certain harmful substances, but also does not have the effect of antibacterial and sterilizing, and cannot provide a safe and comfortable living environment for the occupants. The performance of all aspects needs to be improved, and the existing coatings have many production steps and low production efficiency. , the labor cost is high and needs to be improved.
