Abstract

The invention discloses a water-soluble environment-friendly drawing stick core material. The core material mainly comprises food-grade stearic acid, lauric acid, sorbitol, sucrose, alcohol, talcum powder and a food-grade pigment. The preparation method comprises the following steps: adding food-grade stearic acid, lauric acid, sorbitol and alcohol into a constant-temperature reaction pot, continuously stirring until the materials are completely molten, then slowly adding a sodium hydroxide solution with the concentration of 250 g / L, and continuously reacting for 30 minutes to obtain a mixed solution; adjusting the pH value of the mixed solution to 7.4 to 7.8; continuously adding sucrose under a constant-temperature heating condition, continuously stirring until the sucrose is completely dissolved, and standing for 20 minutes; and adjusting the temperature, then adding talcum powder, the food-grade pigment and food-grade glycerol, and supplementing ethanol to enable the system to obtain the water-soluble environment-friendly colorful rod core material. A colorful rod prepared by the method has the characteristics of safety, environmental protection, writing lubrication and strong water solubility, and is suitable for children.

Description

technical field [0001] The invention relates to the technical field of preparation of painting supplies, and more specifically relates to a water-soluble environment-friendly colorful rod core material and a preparation method thereof. Background technique [0002] Water-soluble colorful sticks, also known as water-soluble painting sticks, first appeared in Japan and were gradually introduced into my country. Water-soluble colorful sticks are generally composed of plastic shells and core materials, and mostly use lipstick-style rotation. Compared with traditional crayons and oil pastels, water-soluble colorful sticks have smooth painting feel, easy coloring, not easy to fall off, and color Bright, clear coating, etc. In addition, the water-soluble colorful stick is water-soluble, can easily make oil painting and watercolor effects, and is especially easy to clean. [0003] At present, the raw materials used in the water-soluble colorful core materials in the market are gene...
