[0030] The preparation method of titanate chelating agent, 20-30 parts of Tyzor371, 10-20 parts of Tyzor212, 8-12 parts of polyacrylamide, 15-25 parts of sodium hexametaphosphate, add 25-34 parts of water, in 90- Stir at 95°C to react into a gel to obtain a gel-like substance, which is a titanate chelating agent. After obtaining the gel-like substance, you can also add 1 part of phenoxyethanol preservative and keep it for later use.
[0031] The environment-friendly boron-free polymer polyvinyl alcohol-based ultra-light clay includes the following raw materials by weight: 60-75 parts of water; 5-15 parts of polyvinyl alcohol, the average degree of polymerization of polyvinyl alcohol is greater than or equal to 2000; titanate 0.1-0.3 parts of chelating agent, 1-3 parts of water-soluble food grade pigment, 8-15 parts of microsphere foaming agent, 1-3 parts of lubricant, 3-8 parts of humectant, 1-5 parts of water-retaining agent, surface active 0.1-0.3 part of the agent, 0.1-0.3...
Embodiment 1
[0047] Titanate chelating agent: add 25 parts of Tyzor371, 15 parts of Tyzor212, 10 parts of polyacrylamide and 20 parts of sodium hexametaphosphate into 29 parts of water, stir at 90-95 ° C, react into a gel, and obtain The gel-like substance is a titanate chelating agent.
Embodiment 2
[0049] The preparation method of titanate chelating agent is to add 20 parts of Tyzor371, 10 parts of Tyzor212, 8 parts of polyacrylamide and 15 parts of sodium hexametaphosphate into 25 parts of water, stir at 90-95 ° C, and react to form a gel shape to obtain a gel-like substance, which is a titanate chelating agent.

Abstract
The present invention provides a titanate chelating agent, an environment-friendly boron-free polymer polyvinyl alcohol-based ultralight clay and a preparation method thereof, a titanate chelating agent, 20-30 parts of Tyzor371, 10-20 parts of Tyzor212, 8-12 parts Polyacrylamide, 15‑25 parts sodium hexametaphosphate. Environmentally friendly boron-free polymer polyvinyl alcohol-based ultra-light clay, water 60-75 parts; polyvinyl alcohol 5-15 parts, the average degree of polymerization of polyvinyl alcohol is greater than or equal to 2000; titanate chelating agent 0.1-0.3 parts, water-soluble 1-3 parts of food grade pigment, 8-15 parts of microsphere foaming agent, 1-3 parts of lubricant, 3-8 parts of humectant, 1-5 parts of water-retaining agent, 0.1-0.3 part of surfactant, water-based dispersant 0.1-0.3 parts. Using polystyrene ultra-light balls, polyvinyl alcohol and titanate chelating agent, the obtained ultra-light clay is boron-free, safe and environmentally friendly, has no irritating odor, excellent tensile properties, non-sticky hands, pure color, and can be adjusted freely. Excellent styling ability.
Description
technical field [0001] The invention relates to ultra-light clay, in particular to a titanate chelating agent, an environment-friendly boron-free polymer polyvinyl alcohol-based ultra-light clay and a preparation method thereof. Background technique [0002] Traditional plasticine and bouncing clay are oil-soluble surface clay. The material is not environmentally friendly and has a pungent smell. A large amount of essence will be added during the production process, and the color is dark and the color is not correct. The two colors cannot be mixed; the modeling ability is not good. Good, no tensile strength, not easy to bond between parts; different parts should be fixed with toothpicks during use, because it is greasy, the kneading process is easy to get dirty; after drying, the product will crack, deform and deteriorate, and the product is heavy. It is easy to swallow, causing great harm to health and causing parents to worry. [0003] The ultra-light clay material is wat...
