Sand play is a property of every child. The toy molding sand is intangible, has good fluidity and plasticity, and soft hand feeling, can stimulate imagination and creativity of children, can be used for manufacturing various models by a mould or freely exerting, and can stimulate the cranial nerves of the children to promote the coordination ability of hands and brains.
However, the toy sand on the market has a series of defects: 1) the illegal trade company uses toxic borax; 2) children are easy to eat by mistake when playing sand; 3) bacteria are easy to breed in the process of playing the molding sand; 4) the molding sand can fade, chip, stick hands and harden after a long time.
Disclosure of Invention
Aiming at the defects of toy molding sand in the background technology, the invention provides a manufacturing method of safe type color toy molding sand.
The invention is realized by the following technical scheme:
a manufacturing method of safe type color toy molding sand comprises the following steps:
1) adding safe and nontoxic inert powder, vinyl-terminated silicone oil, silicone oil-soluble food-grade pigment and a safe hydrosilylation catalyst into a kneading machine for kneading;
2) kneading for one hour, adding hydrogen-containing silicone oil dropwise into the mixture, and continuing kneading for one hour;
3) finally, bendinylammonium, phenoxyethanol and ethylhexylglycerin are added into the kneader and kneaded for two hours to obtain the toy molding sand.
Further, the invention adopts an incomplete addition technology: the total amount of vinyl substances in the vinyl-terminated silicone oil in the step 1) is larger than the total amount of Si-H bond active H groups in the hydrogen-containing silicone oil in the step 2).
Further, the molar ratio of vinyl in the vinyl-terminated silicone oil in the step 1) to Si-H bond active H groups in the hydrogen-containing silicone oil in the step 2) is 1: (0.1-0.3).
The inventor finds that if the toy molding sand is prepared by using the terminal vinyl silicone oil which is not added, the prepared toy molding sand is easy to fade, chip and stick hands in the playing process and is not suitable for playing; the addition of the hydrogen-containing silicone oil to the vinyl silicone oil is carried out, if the vinyl addition in the terminal vinyl silicone oil exceeds 30 percent and is completely added to 100 percent, even if the active H group of the Si-H bond of the hydrogen-containing silicone oil is excessive, the prepared toy molding sand is harder and harder, and the playing experience is seriously influenced.
Further, the viscosity of the vinyl-terminated silicone oil is 500cps, and the vinyl mass fraction of the vinyl-terminated silicone oil is 0.43%.
Further, the content fraction of the Si-H bond active H matrix in the hydrogen-containing silicone oil is 0.5%.
Further, the molding sand comprises the following manufacturing raw materials in parts by weight: 100 parts of safe and nontoxic inert powder, 2 parts of vinyl-terminated silicone oil, 1 part of silicone oil-soluble food-grade pigment, 0.0001 part of safe hydrosilylation catalyst, 0.006-0.018 part of hydrogen-containing silicone oil, 0.0001 part of benzalkonium chloride, 0.2 part of phenoxyethanol and 0.2 part of ethylhexyl glycerol.
Further, the safe and nontoxic inert powder can be any one or a mixture of more of silicon dioxide, fine sand, calcium carbonate, glass beads and flour.
The present invention uses an organosilicon material which is harmless to the human body.
Further, the silicon oil soluble food grade pigment is a colorful food grade pigment which can be dissolved in silicon oil.
Further, the safe hydrosilylation catalyst is a platinum catalyst for a silica gel nipple.
The denatonium benzoate is also added as an aversion agent to prevent children from eating the denatonium benzoate by mistake.
The invention also adds safe preservatives of phenoxyethanol and ethylhexyl glycerin, thereby safely and effectively preventing the breeding of bacteria.
Compared with the prior art, the invention has the beneficial effects that:
the safe toy molding sand is prepared by using a harmless organosilicon material and a safe additive and adopting an incomplete addition technology. The toy molding sand is safe and non-toxic, the conditions of color loss, scrap loss, hand sticking and hardening can not occur due to long-time playing, in addition, the toy molding sand can prevent mistaken eating and mildew and decay, the preparation process is simple, and the toy molding sand is very suitable for being used as a toy for children.
