Problems solved by technology

However, most of the pigment products currently on the market are ordinary chemical pigments. If they contain toxic heavy metals or formaldehyde and other substances, they will cause harm to the human body, especially if they are accidentally eaten by young children, they will damage the health of children to a certain extent. If the paint is stained on the clothing, it is not easy to wash it off
Therefore, there are currently many deficiencies, especially in the pigments used by children.

The yellowpigment comprises the following raw materials in parts by weight: 35-45 parts of gardenia yellow pigment extract, 10-15 parts of potato powder, 10-15 parts of corn starch, 20-30 parts of dextrin, 5-8parts of glycerin, 2-3 parts of a preservative, 1-2 parts of disodium stannous citrate, 0.3-0.5 part of soluble soybean polysaccharides, 0.5-1.5 parts of pectin and 80-110 parts of water. According tothe yellow pigment for child drawing and the preparation method of the yellow pigment disclosed by the invention, formula is reasonable and preparation method is simple, the made pigment does not contain any toxic heavy metal or formaldehyde and any other substances harmful to the human body, is non-toxic, safe and environment-friendly, avoids the condition that child health is harmed because thechild contacts or eats the pigment by mistake, and is easy to clean, particularly suitable for use of children and applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of pigment production technology, in particular to a yellow pigment for children's painting and a preparation method thereof. Background technique [0002] Pigment is a powdery substance used for coloring. It is insoluble in water, oil, resin or organic solvents, but can be uniformly dispersed in these media and can color the medium, and it has a certain covering power. [0003] Since ancient times, the source classification of pigments is mainly mineral source pigments, plant source pigments or animal source pigments and modern chemical synthetic pigments. Rich and colorful pigments have created a rich and colorful world of colors and art, and are the most precious cultural treasures so far. Pigment is a colored fine-grained powder substance. From the chemical composition, it can be divided into inorganic pigments and organic pigments. The inorganic pigments mainly include metal oxides, chromates, carbonat...
