Problems solved by technology

Moreover, the brightness of gouache is improved by diluting, adding powder, or light colors with more silty pigments, so its dry and wet changes greatly.
[0004] Because gouache paints tend to have a large difference in dry and wet color during use, the painting is not smooth, gray and dark after drying, and cracks occur, so researchers have explored various new pigments.

preparation example Construction

[0050] The invention also discloses a preparation method of powder acrylic paint, comprising the following steps:

[0051] Mix and grind 10-15 parts of toner, 0.3-0.5 parts of wetting agent, 0.02-0.05 parts of preservative and 30-40 parts of water to obtain a color paste;

[0052] After mixing 5-15 parts of peach gum liquid and 25-35 parts of acrylic acid emulsion, add 10-15 parts of alkali-swellable thickener, adjust the pH value to 7-8 with alkali, disperse evenly, and obtain a binder;

[0053] The color paste, binder and 5-10 parts of filler are uniformly mixed to obtain powder acrylic paint.

[0054]In the present invention, toner, wetting agent, preservative, water, peach gum, acrylic acid emulsion, alkali-swellable thickener and filler are used as raw materials. The technical solutions are the same and will not be described again.

[0055] figure 1 Represent the present invention to prepare the schematic flow sheet of powder acrylic paint.

[0056] In the present inv...

Embodiment 1

[0067] Mix 10 parts of toner, 0.3 part of wetting agent, 0.05 part of preservative and 30 parts of water evenly, and grind with a three-roll mill. Get the color paste.

[0068] Heat the peach gum at a constant temperature at 80° C. and continue to stir for 2 hours to form a peach gum solution.

[0069] Mix 5 parts of peach gum and 25 parts of acrylic emulsion, add 10 parts of alkali-swellable thickener, add triethanolamine to adjust the pH value to 7.8, and disperse evenly with a high-speed disperser to obtain an adhesive.

[0070] Mix the obtained color paste and binder evenly, add 5 parts of filler, and grind evenly on a three-roll mill again to obtain powder acrylic paint.

Embodiment 2

[0072] Mix 15 parts of toner, 0.5 part of wetting agent, 0.02 part of preservative and 40 parts of water evenly, and grind with a three-roll mill. Get the color paste.

[0073] Heat the peach gum at a constant temperature at 80° C. and continue to stir for 2 hours to form a peach gum solution.

[0074] Mix 15 parts of peach gum and 35 parts of acrylic emulsion, add 15 parts of alkali-swellable thickener, add triethanolamine to adjust the pH value to 7.5, and disperse evenly with a high-speed disperser to obtain an adhesive.

[0075] Mix the obtained color paste and binder evenly, add 5 parts of filler, and grind evenly on a three-roll mill again to obtain powder acrylic paint.

Abstract

The invention provides gouache and acrylic painting pigment. A pH (potential of hydrogen) value of the gouache and acrylic painting pigment is 7-8. The gouache and acrylic painting pigment comprises, by weight, 10-15 parts of toner, 0.3-0.5 part of wetting agents, 0.02-0.05 part of preservatives, 30-40 parts of water, 5-15 parts of peach gum liquid, 25-35 parts of acrylic emulsion, 10-15 parts of alkali swelling type thickeners and 5-10 parts of fillers. The gouache and acrylic painting pigment has the advantages that the peach gum liquid and the acrylic emulsion are jointly used as adhesive, protective films can be formed after the peach gum liquid and the acrylic emulsion are dried, accordingly, the gouache and acrylic painting pigment is excellent in color retention, dry and wet colors of the obtained pigment are consistent with one another, cracking can be prevented, and the gouache and acrylic painting pigment is waterproof; systems are thickened by the alkali swelling type thickeners, thick effects can be realized by electrostatic repulsion by means of salt formation, accordingly, the painting smoothness of products can be improved, and dry and wet color difference can be reduced.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a powder acrylic paint and a preparation method thereof. Background technique [0002] Pigments are powdered substances used for coloring. It is insoluble in media such as water, grease, resin or organic solvents, but can be uniformly dispersed in these media and can color the media, and has a certain covering power. The pigments used in art basically require fine particles, bright colors, and long-lasting color change. Existing art paints include gouache paints, acrylic paints, watercolor paints and the like. [0003] Among them, gouache paint is a relatively common paint used for painting. Gouache paint is a new product obtained by adding white powder to watercolor paint to make the color opaque. Gouache paint is opaque and easy to modify. Gouache pigments are generally prepared from raw materials such as toner, a large amount of fillers, wetting agents, preservatives and binders. ...
