Weather-resisting non-toxic pigment preparing method

Abstract

The invention discloses a weather-resisting non-toxic pigment preparing method and belongs to the field of school article synthesis. The method comprises the steps of exposing cleaned clam shells to the sun to be aged, conducting smashing and screening, conducting calcination to obtain powder, making the powder react with water under the ultrasonic condition, conducting dispersion to obtain white uniform slurry, cutting wheat straw into pieces, soaking the pieces in warm water, spreading the short straw pieces on the bottom of a fermentation tank, covering the short straw pieces with the white uniform slurry, laying Chinese art paper, adding water, conducting airtight fermentation, conducting high-speed stirring to obtain mixed uniform slurry, evenly mixing the mixed uniform slurry with brown sugar and glutinous rice flour in proportion to obtain a stock, mixing the stock with water and pigment in proportion, and conducting uniform ultrasonic dispersion to obtain weather-resisting non-toxic pigment. The pigment can be stored stably, sedimentation and layering are avoided, adhesion fastness and color saturation are high, and the pigment is safe and free of toxin. Paintings drawn with the pigment can be stored for a long term without fading, and the pigment can be widely used and popularized.

Description

technical field [0001] The invention discloses a preparation method of a weather-resistant non-toxic pigment, which belongs to the field of synthesis of school supplies. Background technique [0002] The difference between watercolor painting and oil painting is that it has two basic characteristics: one is that most of the pictures have a transparent visual feeling; Different from the creative techniques, watercolor is transparent, light, bright and moist and smooth. Whether it is the warm and gorgeous sunshine, or the deep and vast ocean, whether it is bright and colorful flowers and trees or cold and hazy clouds, all of them arouse the attention of watercolor painters. The inner color impulse and expressive desire can often draw dreamlike and magnificent pictures. [0003] The watercolor paint is an important factor related to watercolor painting, and the pigment is a powdery or pasty substance used for coloring. It is insoluble in water, grease or organic solvents, but...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: the poor chemical stability of traditional watercolor pigments in the process of preparation and use, under the action of factors such as light, oxygen in the air, and humidity in the air, will change and fade, causing the works to lose their original color. The artistic charm and value, and the preservation life is also greatly shortened. A method for preparing a weather-resistant non-toxic pigment is provided. In the present invention, the clam shells are firstly cleaned and exposed to the sun for aging, crushed and sieved, calcined into powder, and then React with water under ultrasonic conditions and disperse into a white homogenate, then cut the straw short and soak it in warm water, spread the short straw on the bottom of the fermentation tank, cover it with the white homogenate, lay rice paper, add water and ferment , and then stirred at high speed to form a mixed homogenate, mixed with brown sugar and glutinous rice flour in proportion to obtain the base material, then mixed with water and dyes in proportion, and obtained a weather-resistant non-toxic pigment after being uniformly dispersed by super-generation
