Suspension bleeding-proof water-based multicolor basic paint and preparation method thereof

Abstract

The invention discloses a suspension bleeding-proof water-based multicolor basic paint and a preparation method thereof. The basic paint is prepared from the following materials by weight percent: 25-50% of deionized water, 0.3-1.4% of hydroxyethyl cellulose, 0.1-1.5% of PH regulator, 0.2-0.55% of dispersing auxiliary, 0.1-0.3% of wetting auxiliary, 0.1-0.5% of defoaming auxiliary, 1.0-5.0% of titanium dioxide, 10-40% of filler, 15-35% of self-crosslinking elastic emulsion, 0.2-0.6% of bactericidal and mildew-proof agent, 0.5-7.0% of hollow vitrified balls and 5.0-20% of protective colloid solution. The basic paint has the following beneficial effects that by adding the hollow vitrified balls, the density of the multicolor basic paint is greatly reduced and can keep consistent with that of the protective colloid solution, namely 1.03g / cm<3>.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a suspension-type anti-bleeding water-based colorful base paint and a preparation method thereof. [0002] Background technique [0003] Water-based colorful paint is a kind of color particles that are mixed with water-based base paint and water-based color paste into various colors. After mixing these color particles of different colors, each color particle in the water-based system can exist independently of each other. After spraying, it can achieve A multicolored granite effect paint. In recent years, due to its high-grade decorative effect and environmental protection performance, it has been widely promoted and applied in the architectural coating industry. [0004] In the existing production technology of water-based multicolor paint, the density of the multicolor toning base paint is higher than that of the protective colloid solution due to the addit...

AI Technical Summary

Problems solved by technology

Therefore, in the production process, no matter what method is used, the colorful particles in it will precipitate and agglomerate or the color particles will hang after spraying. In order to solve this problem, the viscosity of the finished paint is increased to prevent particle precipitation, but the finished paint After the viscosity is increased, its storage performance is poor due to the precipitation, agglomeration, and color mixing of colorful particles.
