Abstract

The invention discloses water-based universal color paste and a preparing method thereof. The water-based universal color paste is prepared from, by weight, 5-20 parts of deionzied water, 15-30 partsof acrylic modified polyurethane resin, 2-5 parts of glycerinum, 5-10 parts of a dispersing agent, 0.1-0.5 part of a defoaming agent, 0.3-0.5 part of a thickening agent, 0.1-1 part of a pH regulator,1-3 parts of a small-molecule-weight wetting agent, 0.1-0.5 part of a preservative and 25-50 parts of pigment. The prepared water-based universal color paste is good in mobility, small in chromatic aberration, high in stability and well compatible with various coating systems, a paint film has an excellent surface effect after the color paste is mixed with basic paint, and the color paste does notcontain VOC, is safe and environmentally friendly, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based universal color paste and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for the decorative performance of various coatings, the application of color paste is becoming more and more extensive. Compared with pigments, color paste has the advantages of convenient addition, easy volume measurement, good compatibility with paint, and easy dispersion. There are many types of colorants currently on the market, but there are few colorants that are generally used in automotive coatings. There are two kinds of color pastes: pure water paste and color paste added with general resin. Pure water slurry does not add general-purpose resin, and uses water as the dispersion medium. It will not cause compatibility problems with the base paint during color matching. However, during subsequent storage and use, the color pas...
