Problems solved by technology

Some researchers believe that long-term excessive intake of boron has toxic effects on human reproduction, development and endocrine system
Although some manufacturers use borax to make the boron element migration in ultra-light clay can meet the current existing detection standards, but as consumers and the market have higher and higher requirements on the quality and safety technology of children's art supplies, the content of Boron's children's art supplies will gradually be abandoned by consumers and the market

Embodiment approach

[0028] According to one embodiment of the present invention, the preparation method also includes: S5, placing the mixed material formed in step S4 in a molding device, and packaging to obtain water-based boron-free ultralight clay.

[0029] The present invention is further described below by specific examples. However, these examples are only exemplary and do not constitute any limitation to the protection scope of the present invention.

[0030] In the following examples and comparative examples, the reagents, materials and instruments used are commercially available unless otherwise specified.

Embodiment 1

[0032] A kind of ultra-light clay, its component is: the model of 2wt% is the carbomer resin of Lubrizol 940, the triethanolamine of 2.5wt%, the foaming agent of Expancel 920DU 80 of 5wt%, the essence of 0.1wt%, 2wt% % pigment, 0.1 wt% denatonium benzoate, 1 wt% sodium carboxymethylcellulose, 1 wt% glycerin and 86.3 wt% water.

[0033] The above-mentioned ultralight clay was prepared by the following steps:

[0034] (1) Dissolve Lubrizol 940 Carbomer in cold water, place at room temperature for 24 hours, dissolve until the whole is uniform and free of granular substances;

[0035] (2) Add the semi-finished product obtained in step (1) into the kneader, add Expancel 920DU 80 foaming agent, and then start the kneader and stir for 30 minutes;

[0036] (3) Open the kneader, add essence, pigment, denatonium benzoate, sodium carboxymethyl cellulose, glycerin successively in the kneader, stir and knead evenly;

[0037] (4) Add triethanolamine at last, adjust the pH of material betw...

Embodiment 2

[0042] An ultra-light clay, its components are: 1wt% Lubrizol 934 carbomer, 1.3wt% triethanolamine, 6wt% Expancel 920DU 120 foaming agent, 0.1wt% essence, 2wt% pigment, 0.1 wt% denatonium benzoate, 1 wt% sodium carboxymethylcellulose, 1 wt% glycerin and 87.5 wt% water.

[0043] The above-mentioned ultralight clay was prepared by the following steps:

[0044] (1) Dissolve Lubrizol 934 Carbomer in cold water, place at room temperature for 24 hours, dissolve until the whole is uniform and free of granular substances;

[0045] (2) Add the semi-finished product obtained in step (1) into the kneader, add Expancel 920DU 120 foaming agent, and then start the kneader and stir for 30 minutes;

[0046] (3) Open the kneader, add essence, pigment, denatonium benzoate, sodium carboxymethyl cellulose, glycerin successively in the kneader, stir and knead evenly;

[0047] (4) Add triethanolamine at last, adjust the pH of the material between 6-8, mix well;

[0048] (5) Put it in a molding d...

Abstract

The invention provides water-based boron-free ultralight clay, which is prepared from the following components in percentage by weight: 0.5 to 3.0 percent of carbomer, 1.0 to 2.5 percent of neutralizing agent, 3 to 10 percent of foaming agent, 0.1 to 0.2 percent of essence, 0.5 to 3.0 percent of pigment, 0.1 to 0.3 percent of bitter agent, 2 to 5 percent of humectant and 80 to 95 percent of water, wherein the total mass of the water-based boron-free ultralight clay is 100 percent. The ultralight clay does not contain boron and is high in safety. In addition, carbomer adopted by the invention belongs to a natural medicinal component and can play roles in diminishing inflammation and sterilizing. A certain affinity for skin is achieved, carbomer is added into the ultralight clay, so that the effects of protecting the skin, reducing irritation and preventing various allergic symptoms can be achieved.

Description

technical field [0001] The invention relates to the technical field of ultra-light clay, in particular to a safe boron-free ultra-light clay in an aqueous system and a preparation method thereof. Background technique [0002] Ultra-light clay has strong plasticity and bright colors, and craftsmen can freely knead and create freely. It is the latest hand-made material that combines the advantages of clay, paper clay, sculpture clay, plasticine, etc. It can be used in perfect combination with wood, metal sheet, sequins, glass and other materials. The works made of ultra-light clay are not only It needs to be grilled, it can be air-dried naturally within 24-48 hours and is elastic, not crumbling, and can be stored forever. [0003] At present, ultra-light clay products on the domestic market are mainly composed of polyvinyl alcohol, borax, water, foaming agent, coloring agent and moisturizing agent, and its main elastic structure is a gel formed by the reaction of polyvinyl al...
