Problems solved by technology

The main colors of plant pigments are navy blue, rouge, gamboge, etc., which are non-toxic and harmless, non-allergic and carcinogenic to the skin, biodegradable and environmentally compatible, but have low yield and poor dyeing reproducibility and low firmness, light resistance, poor temperature resistance, etc.; mineral raw materials mainly include cinnabar, stone yellow, stone green, etc., with strong covering ability, good stability, and no discoloration, but poor permeability and poor water resistance; chemical fusion Pigments include dawn, deep red, scarlet, chrome yellow, sky blue, etc., containing organic pigments, good coloring power, easy to spread and process and grind, good resistance, easy to use, but will fade
In order to improve the light resistance of pigments, the current main solution is to add organic light stabilizers to the combination. Because light stabilizers are pure organic compounds, they have disadvantages such as volatile, blooming, migration, and being extracted by solvents. This not only affects the The persistence of its effectiveness, but also lead to environmental pollution

Abstract

The invention discloses an environmentally friendly light-resistant traditional Chinese painting pigment and a preparation method thereof and belongs to the field of art pigment products. The pigment is prepared from a sorghum red pigment, carmine, sodium alginate, fatty acid polyoxyethylene ester, modified sorghum starch, 2-hydroxyl-4-methoxyl diphenyl ketone, glycerin, pork fat, carboxymethyl cellulose, polydimethylsiloxane and deionized water. The sorghum red pigment extracted by using waste sorghum shells as a raw material serves as a main pigment base material, a small amount of carmine and the pork fat serve as auxiliary base materials, and then the base materials are matched with other auxiliary materials to prepare the pigment, and the pigment is low in cost, good in light resistance, strong in permeability, bright in color, fine, uniform, high in stability, good in water proofing and oil proofing property, safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of art pigment supplies, and relates to a traditional Chinese painting pigment, in particular to an environment-friendly light-resistant traditional Chinese painting pigment and a preparation method thereof. Background technique [0002] Chinese painting pigments, also called Chinese painting pigments, are special pigments used for painting Chinese paintings. Traditional Chinese painting pigments are mainly divided into three categories: mineral pigments, plant pigments and chemical fusion pigments. The main colors of plant pigments are navy blue, rouge, gamboge, etc., which are non-toxic and harmless, non-allergic and carcinogenic to the skin, biodegradable and environmentally compatible, but have low yield and poor dyeing reproducibility and low firmness, light resistance, poor temperature resistance and other shortcomings; mineral raw materials mainly include cinnabar, stone yellow, stone green, etc., with strong ...
