Abstract

The invention discloses a water-resistant latex paint coloring system, which is composed of color paste and water-resistant base paint, wherein the color paste consists of 5-30% of dispersant and 0.5-5.0% of defoaming agent by weight percentage agent, 1-20% co-solvent, 50-70% inorganic (organic) pigment, 0.1-1.0% preservative, 0.1-1.0% pH regulator and 10-30% water; the base paint is composed of 10-20% by weight of co-solvent, 0.1-1% of dispersant, 0.1-1% of wetting agent, 0.1-1% of defoamer, 10-20% of rutile titanium dioxide, 5-15% heavy calcium, 5-15% wollastonite powder, 12-40% pure acrylic, styrene-acrylic emulsion, 1-2% film-forming aid, 0.1-1% hydroxyethyl cellulose ether, 0.1-1 % alkali-swellable polyacrylic acid thickener, 0.1-1% polyurethane associative thickener, 0.1-1% preservative, 0.1-1% pH regulator and 5-15% water. The color paste is added to the water-resistant base paint according to the addition amount of 2-5% of the coloring system, and this water-resistant latex paint coloring system is formed, which overcomes the defects of poor water resistance and short service life of traditional latex paints .

Description

technical field [0001] The invention relates to a latex paint coloring system, in particular to a water-resistant latex paint coloring system based on base paint and color paste. Background technique [0002] Colorful latex paint is becoming the leading product for building exterior wall decoration. Colored latex paint is a color matching system composed of water-based color paste and basic white paint or varnish. The water-based color paste is composed of pigments, water and various additives; the base paint is divided into white base paint containing titanium dioxide and varnish without pigment. Water-based color paste is used for white base paint to prepare light-colored finished paint, and for varnish to prepare dark-colored finished paint. [0003] The water resistance of latex paint film depends on the water resistance of water-based color paste and base paint. If the water-based color paste uses a large amount of hydrophilic surfactants to disperse the pigments in w...
