Light-weight clay

Abstract

The invention discloses light-weight clay, which consists of the following components in percentage by mass: 8.0 to 20.0 percent of water soluble resin, 26.9 to 85.75 percent of water, 0.05 to 0.1 percent of kathon, 1.0 to 20.0 percent of humectant, 2.0 to 10.0 percent of xanthan gum, 2.0 to 15.0 percent of light-weight padding powder, 1.0 to 8.0 percent of borax and 0.2 to 1.5 percent of colorant. Compared with the conventional clay in the prior art, the light-weight clay has the advantages of easy forming, good handfeel, no greasiness, little possibility of mildewing, long quality guarantee period, innocuity and no peculiar smell.

Description

technical field [0001] The invention relates to the technical fields of handicraft sculpture and art painting paint, in particular to a non-toxic, ultra-light and long-lasting lightweight clay. Background technique [0002] Traditional clay or plasticine is generally based on paraffin, rubber, polyvinyl chloride paste resin, etc., and contains a large amount of plasticizers, such as dibutyl phthalate or dioctyl phthalate, Vaseline etc. This kind of plasticine has poor adaptability to temperature difference (hard in winter and hard to pinch, hot in summer and easy to stick to hands), and more importantly, its components can cause certain toxicity, pollute the environment, and are harmful to the body. [0003] In order to overcome the above problems, this plasticine has been basically replaced by flour plasticine, which is also called "colored clay" on the market. The main ingredients of colored clay are flour and water. This kind of colored clay has the advantages of non-t...

Problems solved by technology

However, the amount of gelling agent added is difficult to control, that is, it is difficult to grasp the degree of gelation of PVA.

At the same time, since the gelation of PVA by borax is thermally reversible, the ambient temperature has a greater impact on the degree of gelation.
