A special drawing pigment for opera murals and preparation method thereof

Abstract

The invention discloses a drawing pigment specially used for opera murals and a preparation method thereof. The drawing pigment is prepared from the following raw materials in parts by weight: 20-25 parts of annatto, 15-18 parts of lac red, and 2-3 parts of talcum powder 3-4 parts of polysorbate, 6-7 parts of polyvinyl alcohol, 2-6 parts of hydroxymethyl cellulose, 7-8 parts of methyl pentanol, 2-4 parts of silica powder, polytetrafluoroethylene 3-5 parts of powder, 50-80 parts of deionized water; the steps of the preparation method of the drawing pigment are: stirring the prepared raw materials to obtain a mixed solution, grinding the mixed solution, and screening the ground mixed solution to obtain a special color for opera murals Drawing pigments; by adding polytetrafluoroethylene powder and silica powder to the raw materials for the preparation of pigments, the wear resistance and high temperature resistance of the mural are improved. By controlling the rotation of the grinding tank and the grinding disc in the opposite direction, the To improve the grinding effect, the grinding mechanism can freely adjust the height of the grinding disc to control the grinding degree.

Description

technical field [0001] The invention relates to the technical field of pigment preparation, in particular to a special drawing pigment for opera murals and a preparation method thereof. Background technique [0002] The patent document (CN103694758B) discloses a bio-environmental protection pigment for art design. The pigment is not easy to fall off and change color when exposed to light, and is resistant to steam and humid environments, but the pigment does not have good wear resistance. The pigment is used in outdoor Opera murals are prone to wear and tear when exposed to wind and sun, resulting in a reduction in the service life of the murals, and the aesthetics of the worn opera murals will also be greatly reduced. The traditional drawing pigment preparation process is inefficient and cannot meet production requirements. , in the production and grinding process of drawing pigments, the grinding effect is relatively poor, and the finished product is single, so it is impos...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of drawing pigment specially used for opera murals and its preparation method. The present invention adds polytetrafluoroethylene powder to the preparation raw materials of the painting pigments so that after the painting pigments are colored on the murals, the color of the murals is improved. Excellent wear resistance, thus ensuring the service life of the murals. The preparation raw materials of the painting pigments also add silica powder, which has high temperature resistance and can adapt to higher ambient temperatures. It solves the problem that the existing opera murals are not wear-resistant. , after a long period of wind and sun, it is easy to fall off, and the technical problem is that the service life is short;
