Environment-friendly aqueous multicolor paint and preparation method thereof

Abstract

The invention relates to an environment-friendly aqueous multicolor paint and a preparation method thereof. The invention belongs to the technical field of multicolor paint. The material formula of the environment-friendly aqueous multicolor paint is as follows: component A: 3 to 14 parts of montmorillonite, 0 to 1.0 part of sodium hexametaphosphate, 0 to 1.2 parts of anhydrous sodium pyrophosphate, 0 to 1.0 part of pH regulator and 86 to 97 parts of water; component B: 20 to 80 parts of water, 8 to 15 parts of granular colloid solution, 0.1 to 0.5 parts of defoaming agent, 0.1 to 0.5 parts of anionic / nonionic wetting dispersant, 2 to 40 parts of pigment filler, 0.6 to 1.5 parts of composite coupling resin, 0.05 to 0.2 parts of preservative, 0.05 to 0.15 parts of pH regulator and 2 to 30 parts of elastic self-crosslinking latex; component C: 10 to 70 parts of acrylic latex, 0 to 4 parts of propylene glycol, 4 to 15 parts of film-forming auxiliary and 1 to 1.5 parts of bactericide. The preparation method for the environment-friendly aqueous multicolor paint includes the following steps of: (1) granular colloid solution preparation; (2) colorful granule preparation: the preparation of white base paint, colorful base paint and colorful granules; and (3) paint production: the latex component C is prepared, and the aqueous multicolor paint is produced. The invention has the advantages of simple process, stable quality, excellent properties, low cost, high weather fastness, high fidelity and good decorative and protective properties.

Description

technical field [0001] The invention belongs to the technical field of colorful paints, in particular to an environment-friendly water-based colorful paint and a preparation method thereof. Background technique [0002] At present, the water-based of architectural coatings has become an inevitable trend, because its non-toxic and excellent performance makes it the best substitute for traditional oil-based systems. The water-based of colorful coatings is also an inevitable development. Friendly features, and the decorative effect it gives to buildings is far beyond ordinary single-color water-based paints. [0003] Due to the high cost and limited resources of natural marble, coupled with the difficulty of construction, harsh wall requirements, and the inevitable risk of falling off, it has become a bottleneck for architectural decoration. Water-based colorful coatings can not only give buildings a real stone-like aesthetic, but also eliminate natural marble The hidden dange...

AI Technical Summary

Problems solved by technology

[0004] Traditional water-based colorful paints use polyvinyl alcohol, xanthan gum, etc. as protective glue, and the colorful paints produced have poor storage stability and poor weather resistance

Most of the water-based colorful coatings produced use RD as the protective colloid, which not only has common problems such as poor storage stability, cumbersome production process, and small particles, but also has high cost, shortage of raw materials, difficult construction, high wall requirements, and harsh production conditions.
