Abstract
The invention relates to an alkali-resistant latex paint. The invention is characterized in that the alkali-resistant latex paint comprises the following components in percentage by mass: 30-50% of epoxy resin, 15-25% of deionized water, 10-15% of superfine ground calcium carbonate, 5-10% of superfine calcined kaolin, 5-10% of wollastonite, 1-3% of nano silicon dioxide, 0.5-1% of dispersing agent, 0.1-0.5% of bactericidal preservative, 0.5-1% of defoaming agent, 1-3% of film forming assistant, 0.1-0.2% of dispersing agent, 0.3-0.5% of humectant, 6-8% of inorganic antalkali, 0.2-0.6% of leveling agent, 0.1-0.5% of thickener and 0.1-0.5% of elastic emulsion. The dispersing agent is an ultralow-molecular potassium salt dispersing agent free of VOC (volatile organic compound), has the advantages of obvious dispersion effect, high dispersion efficiency and no toxicity, and can not pollute the environment. The alkali-resistant latex paint has the advantages of high adhesive force and high hardness. By adding the elastic emulsion, the alkali-resistant latex paint also has the advantages of high elongation percentage, high rebound rate, favorable hand feeling and low tendency to cracking.
Description
[0001] technical field [0002] The invention relates to a latex paint, in particular to an alkali-resistant latex paint, which belongs to the field of chemical industry. Background technique [0003] If the latex paint is painted on the wall or the surface of the article, it will be corroded and alkalized after a long time, which will not only affect the appearance but also cause economic losses. . Contents of the invention [0004] Its components and mass ratio are: 30%-50% epoxy resin; 15%-25% deionized water; 10%-15% ultra-fine ground calcium carbonate, 5%-10% ultra-fine calcined Kaolin, 5%-10% wollastonite, 1%-3% nano-scale silica; 0.5%-1% dispersant; 0.1%-0.5% bactericidal preservative; 0.5%-1% disinfectant Foaming agent; 1%-3% coalescent; 0.1%-0.2% dispersant; 0.3%-0.5% wetting agent; 6%-8% inorganic anti-alkali agent; 0.2%-0.6% fluid Leveling agent; 0.1%-0.5% thickener; 0.1%-0.5% elastic emulsion. [0005] Wherein the dispersant used is a dispersant of potassiu...
