Problems solved by technology

At present, many wall paints cannot solve or completely solve these problems, especially the environmental protection and safety problems of the living environment. The main reason is that the currently used wall paints only focus on the surface properties of the paint, such as: water and alkali resistance , elasticity, scrub resistance and other properties, but its volatile organic compound (hereinafter referred to as VOC) content, antibacterial, air purification, adsorption of harmful substances such as smoke and dust, and humidity adjustment are not good or not effective enough, not safe and environmentally friendly

Abstract

The invention discloses a diatom ooze wall paint formula and a preparation process thereof. The wall paint comprises the following components in percentage by weight: 20-30% of water, 0.5-1% of dispersant, 0.1-0.2% of surfactant, 0.4-0.8% of defoamer, 0.8-3.5% of ethylene glycol, 10-25% of titanium dioxide, 5-25% of diatomite, 15-45% of pure acrylic emulsion, 0.8-1.5% of polyurethane thickener, 0.1-0.2% of preservative, 0.2-0.7% of mildew preventive and 1-2.5% of coalescing agent. The preparation process of the wall paint comprises the following step of: sequentially adding the dispersant, the surfactant, the defoamer, ethylene glycol, titanium dioxide, diatomite, pure acrylic emulsion, the polyurethane thickener, the preservative, the mildew preventive and the coalescing agent into water. The wall paint prepared by the formula and process has the advantages of resisting bacteria continuously, purifying air, absorbing harmful substances such as soot, adjusting humidity, preventing mildew and algae, maintaining water tolerance of the paint film, resisting alkali and the like.

Description

【Technical field】 [0001] The invention relates to a wall paint used for foundation construction, in particular to a formula of diatom mud wall paint and a preparation process thereof. 【Background technique】 [0002] In home decoration, problems such as excessive formaldehyde limit, wall cracks, blooming, mildew, water leakage, and anti-fouling have long plagued people's home life, and these problems can be solved by painting wall paint. At present, many wall paints cannot solve or completely solve these problems, especially the environmental protection and safety problems of the living environment. The main reason is that the currently used wall paints only focus on the surface properties of the paint, such as: water and alkali resistance , elasticity, scrub resistance and other properties, but its content of volatile organic compounds (hereinafter referred to as VOC), antibacterial, air purification, adsorption of harmful substances such as smoke and dust, and humidity adju...
