Embodiment 1
[0040] The raw material composition of a kind of children's color mud is as shown in table 1:
[0043] Preparation of the above-mentioned children's color mud:
[0044] S1: Add dimethyl hydroxy silicone oil, boric acid, and ferric chloride into a kneader, and react at 156°C for 6 hours to obtain an oily colloid;
[0045] S2: add liquid paraffin and vaseline, stir evenly;
[0046] S3: Then add lauric acid and stir to form a soft gel;
[0047] S4: Finally, add sodium benzoate, ethylparaben, starch and pigment, and stir to shape.

Abstract
The invention discloses a preparation method and application of non-dry colored clay for children, and relates to the technical field of plasticine. The preparation method of the colored clay for children comprises the following steps: S1, adding dimethyl hydroxyl silicone oil, boric acid and ferric trichloride into a kneading machine, and reacting at 120-180 DEG C for 2-10 hours to obtain oily colloid; s2, adding a lubricant, and uniformly stirring; s3, adding a dispersing agent, and stirring to form flexible glue; and S4, finally, adding the preservative, the starch and the pigment, and stirring and forming. The prepared colored clay for children has excellent stretchability and plasticity, and is not dry and hard after being placed in air for a long time, so that the service life of the colored clay is prolonged; meanwhile, the colored clay has good self-healing capability, bright color, difficulty in decoloration and better color fading resistance.
Description
technical field [0001] The invention belongs to the technical field of plasticine, and in particular relates to a preparation method and application of non-drying children's colored clay. Background technique [0002] The oily plasticine sold on the market is composed of flour, grease, talcum powder, calcium carbonate powder, mineral powder, spices, pigments, preservatives, advertising pigments, industrial pigments and water. Flour is mixed with water at room temperature, and its bonding performance is low. After mixing talcum powder, calcium carbonate powder and mineral powder with water, they cannot form mineral colloids, and they are completely bonded together by relying on flour and oil. This plasticine has poor plasticity, and the finished product after making is prone to dryness, cracking, deformation, mildew and deterioration, and also makes the operator have a greasy feeling in the hands of the production process, and the repeated use effect is not good. And flour c...
