Problems solved by technology

[0002] At present, when coloring pigments, pigments of different colors are easy to cross colors and mix colors in a wet state, and the boundaries between adjacent places are unclear. Even after drying, the above problems will occur;
[0003] The existing wetting and dispersing agents are used to prevent re-agglomeration or precipitation of pigments and filler particles. They are divided into two types: traditional ionic surfactants and new polymer surfactants. Wetting and dispersing agents have a common property, that is, drying After the film is formed, it absorbs moisture and causes hydrolysis
If this type of wetting and dispersing agent is used in a water-based acrylic paint system, after the paint film on the surface of the painting dries, it will absorb moisture and hydrolyze, and the paint film will be hydrolyzed and softened, making the paint film stick to each other when in contact. It is difficult to keep the three-dimensional picture clean and clear, which affects the final painting effect

Embodiment 1

[0014] Mix 40 parts of acrylic emulsion, 60 parts of water-based resin, and 0.7 parts of silane coupling agent, heat to 40°C, and obtain solution A after cooling; mix 15 parts of water-based polyvinyl acetate, 7 parts of gelatin, 8 parts of alginate, Mix 55 parts of water, heat to 90°C, stir evenly, and obtain solution B after cooling; after mixing solution A and solution B, add 1 part of propylene glycol, 25 parts of pigment, 0.6 part of dispersant, and 15 parts of filler, and heat to Stir evenly at 45°C to obtain water-based paint with strong three-dimensional effect.

[0015] The pigments are organic pigments of various colors; the dispersant can be sodium methylene dinaphthalene sulfonate; the filler can be calcium carbonate; the water-based resin can be water-based alkyd.

Embodiment 2

[0017] Mix 50 parts of acrylic emulsion, 30 parts of water-based resin, and 0.3 parts of silane coupling agent, heat to 45°C, and obtain solution A after cooling; mix 30 parts of water-based polyvinyl acetate, 12 parts of gelatin, 6 parts of alginate, Mix 50 parts of water, heat to 80°C, stir evenly, and obtain solution B after cooling; after mixing solution A and solution B, add 1 part of propylene glycol, 25 parts of pigment, 0.6 part of dispersant, and 15 parts of filler, and heat to Stir evenly at 55°C to obtain water-based paint with strong three-dimensional effect.

[0018] The pigment is an inorganic pigment; the dispersant can choose DISPERBYK-190; the filler can choose kaolin; the water-based resin can choose water-based polyurethane.

Embodiment 3

[0020] Mix 45 parts of acrylic emulsion, 45 parts of water-based resin, and 0.5 parts of silane coupling agent, heat to 42°C, and obtain solution A after cooling; mix 23 parts of water-based polyvinyl acetate, 10 parts of gelatin, 7 parts of alginate, Mix 52 parts of water, heat to 85°C, stir evenly, and obtain solution B after cooling; after mixing solution A and solution B, add 1.5 parts of propylene glycol, 27 parts of pigment, 0.4 parts of dispersant, and 23 parts of filler, and heat to Stir evenly at 50°C to obtain water-based paint with strong three-dimensional effect.

[0021] The pigment is a mixture of organic pigments and inorganic pigments of various colors; the dispersant is a mixture of sodium methylene dinaphthalene sulfonate and DISPERBYK-190, and the weight ratio of sodium methylene dinaphthalene sulfonate and DISPERBYK-190 is 1:1 The filler is a mixture of calcium carbonate and kaolin, the weight ratio of calcium carbonate and kaolin is 2:1; the water-based re...

Abstract

The invention discloses a water-based painting pigment with strong stereoscopic impression. The water-based painting pigment is prepared from the following components in parts by weight, 40 to 50 parts of an acrylic emulsion, 30 to 60 parts of a water-based resin, 15 to 30 parts of water-based polyvinyl acetate, 0.3 to 0.7 part of a silane coupling agent, 7 to 12 parts of gelatin, 6 to 8 parts ofseaweed gel, 1 to 2 parts of propylene glycol, 50 to 55 parts of water, 25 to 30 parts of a pigment, 0.2 to 0.6 part of a dispersing agent and 15 to 30 parts of a filler. A paint film is not prone tosoftening after painting drying, and the three-dimensional painting effect is guaranteed.
