Problems solved by technology

Inorganic pigments have low cost, good heat resistance and relatively stable color, but the color and tone are limited and not bright
Compared with ordinary inorganic pigments, organic pigments usually have higher tinting strength, the particles are easy to grind and disperse, not easy to precipitate, and the colors are brighter, but their light resistance, heat resistance and weather resistance are poor.
[0003] At present, the art paints on the market use chemical monomers as the main raw materials. In the process of formula design, the medium and working conditions of the paints are not fully considered. The quality of the paints is uneven. Problems such as poor saturation and light coloring directly affect the quality of the painting

Abstract

The invention discloses an art pigment. The art pigment is prepared from the following raw materials in parts by weight: 20-40 parts of guar gum, 10-20 parts of distilled water, 15-23 parts of naturalpigment, 3-10 parts of methyl methacrylate, 5-8 parts of tert-butylhydroquinone, 4-8 parts of polyethylene glycol, 1-5 parts of titanium dioxide, 3-7 parts of talcum powder, 7-12 parts of acrylic latex, 2-6 parts of an anti-settling agent and 2-6 parts of a surfactant. According to the invention, the art pigment is prepared by using a reasonable formula, and has the advantages of excellent performance, good light resistance, good heat resistance, good weather resistance, good coloring power, good dispersibility, fine quality, bright color, stable chemical property, strong adhesion and the like.

Description

technical field [0001] The invention relates to the field of pigments, in particular to an art paint and a preparation method of the art paint. Background technique [0002] Pigment is a substance that can make objects dyed with color. It is a commonly used material in art painting, and there are many types. At present, there are two kinds of general-purpose art pigments: organic pigments and inorganic pigments. Inorganic pigments are low in cost, relatively good in heat resistance, and relatively stable in color, but their colors and hues are limited and not bright. Compared with ordinary inorganic pigments, organic pigments usually have higher tinting strength, the particles are easy to grind and disperse, not easy to precipitate, and the colors are brighter, but their light resistance, heat resistance and weather resistance are poor. [0003] At present, the art paints on the market use chemical monomers as the main raw materials. In the process of formula design, the m...
