Environment-friendly art pigment for preschool children and preparation method thereof

Abstract

The invention discloses an environment-friendly art pigment for preschool children and a preparation method thereof. The environment-friendly art pigment for preschool children is prepared from the following raw materials in parts by weight: 6-8 parts of vegetable gum, 7-9 parts of acrylic emulsion, 22-25 parts of pigment powder, 3-6 parts of calcium propionate, 5-8 parts of starch ether, 2-4 parts of glycerol, 20-24 parts of an adhesive, 1.5-2 parts of a bacteriostatic agent, 8-11 parts of chitosan modified talcum powder, 0.8-1 part of xylooligosaccharide and 15-20 parts of distilled water. The adopted raw materials are very environmentally friendly, the vegetable gum, the starch ether and the xylooligosaccharide are extracted from pure natural plants and do not contain harmful substances, by adopting the preparation method, all the components of the pigment can be mixed more uniformly and comprehensively, the color of the prepared pigment is purer, and the slurry drying device adopted in the preparation method disclosed by the invention can be used for simultaneously and respectively drying the flowing slurry in the four drying cylinders, so that the efficiency of preparing the pigment by the preparation method disclosed by the invention is greatly improved.

Description

technical field [0001] The invention relates to a watering and moisturizing system, in particular to an environment-friendly art paint for preschool children and a preparation method thereof, belonging to the application technical field of the watering and moisturizing system for mushroom planting. Background technique [0002] In the process of preschool children learning art painting, art paints are indispensable. There are many kinds of art paints, and there are different types of art paints. There are inorganic and organic differences in art. Inorganic pigments are generally mineral substances. Humans have known for a long time to use inorganic pigments, using colored soil and ores, to paint on rock walls and smear their bodies. Organic pigments are generally obtained from plants and marine animals. [0003] Existing art paints for preschool children still have great defects in use. Existing art paints for preschool children are not environmentally friendly enough in us...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing art paints for preschool children are not environmentally friendly when used, contain more harmful substances, and are not safe and healthy to use; the existing art paints are water-resistant, alkali-resistant, and stain-resistant. And anticorrosion is very poor, causes pigment to be able to store the time of quality guarantee very short, and the adhesive force of pigment and paper is very weak when using; Existing art pigment is easy to fade, and easily changes color under light; Existing art The drying efficiency of the pigments during the preparation process is very slow, and when the raw materials of the pigments are dried, the raw materials of the pigments cannot be further mixed, resulting in the existing art pigments having low color purity and poor stacking plasticity after preparation. It is a good question, but to propose a kind of environmental protection art paint for preschool children and its preparation method
