Problems solved by technology

[0002] At present, the fillers used in latex paints on the market are generally light calcium powder, talcum powder, heavy calcium powder, etc. These fillers have the disadvantage of poor strength, and are easily pulverized after long-term oxidation and ultraviolet radiation; used for interior and exterior of latex paint In wall decoration, over time, the paint will be pulverized, and the original particles will be pulverized again, floating around with the air, causing environmental pollution

Abstract

The invention relates to environment-friendly high-strength emulsion paint and a preparation method thereof. The emulsion paint is prepared from, by weight, dispersing agents, defoaming agents, quartz powder, kaolin, titanium dioxide, 2-amino-2-methyl-1- propyl alcohol, propylene glycol, emulsion and water. The preparation method comprises the steps of 1, pouring the water into a container, and starting stirring; 2, adding the dispersing agents and part of the defoaming agents, conducting stirring, then adding the kaolin, the titanium dioxide and the quartz powder, and then conducting dispersion for about 30 minutes; 3, after the mixture is dispersed uniformly, adding the 2-amino-2-methyl-1- propyl alcohol, the propylene glycol and the remaining defoaming agents, and conducting dispersion till the mixture gets uniform and no particle exists; 4, adding the emulsion, and conducing dispersion for about 30 minutes. The environment-friendly high-strength emulsion paint has the effective advantages of being environment-friendly, mildew-proof, alkali-resistant, free of color fading and chalking, scrubbing-resistant, great in adhesion, good in application property and high in covering power and is a top-selection competitive product for building wall decoration of houses, offices, projects and the like.

Description

technical field [0001] The invention relates to a paint in the construction field, in particular to a multi-functional, environment-friendly, high-strength latex paint and a preparation method thereof. Background technique [0002] At present, the fillers used in latex paints on the market are generally light calcium powder, talcum powder, heavy calcium powder, etc. These fillers have the disadvantage of poor strength, and are easily pulverized after long-term oxidation and ultraviolet radiation; used for interior and exterior of latex paint In wall decoration, over time, the paint will be powdered, and the original particles will be pulverized again, floating around with the air, causing environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a kind of environment-friendly high-strength latex paint and preparation method thereof. The purpose of the present invention is to realize through the following technical solut...
