Production method of fluorescent colour attapulgite clay

Abstract

The invention discloses a production method of fluorescent colour attapulgite clay. The method comprises the following main steps of: adding a fluorescent colour sand attapulgite mixture into a running horizontal type flour-mixing machine, slowly adding sodium polyacrylate gel solution into the fluorescent colour sand attapulgite mixture, and stirring to form a fluorescent colour blocky attapulgite mixture; and spraying methyl silicone oil onto the fluorescent colour blocky attapulgite mixture, kneading to form a semi-finished product of fluorescent colour attapulgite clay, finally pressing to form flat plate type fluorescent colour attapulgite clay, and sealing and packaging the flat plate type fluorescent colour attapulgite clay to obtain the product. The fluorescent colour attapulgite clay has high viscosity and good flexible plasticity, and has the characteristics of low contractibility rate, capability of becoming hard after naturally drying without baking, no generated crack, no corrosivity and no greasy feel. The fluorescent colour attapulgite clay can bring a charming fluorescent visual effect and is suitable for making fluorescent colour patterns, moulds and handiworks.

Description

technical field [0001] The invention relates to pottery clay, in particular to a production method of fluorescent colored attapulgite soft clay. Background technique [0002] Soft clay is a kind of artificially synthetic clay with strong plasticity. Put the finished product into the oven and bake it lightly, and it will produce hard and colorful painted pottery handicrafts. [0003] The main raw materials of soft clay are polyvinyl chloride and calcium carbonate. The adhesion is not good at room temperature, and it is easy to age and fade after long-term storage. It is easy to foam when baking soft clay. If the temperature exceeds 200 ° C, it will not only make The finished product is scorched and melted, and may even cause combustion, generating irritating and toxic fumes containing chlorine. The sales price of soft clay is relatively high, which is not conducive to popularization and use. [0004] The Chinese patent publication number is: CN 101186736, open date: May 28, ...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of the above-mentioned patents is that the main raw materials of the soft clay produced by this technology are polyvinyl chloride paste resin, dizinc grease and calcium carbonate, and the adhesion is not good under normal temperature, which is not conducive to making molding. Dizinc grease belongs to toxic substances

[0007] The disadvantages of the above-mentioned patents are: the fillers described in the luminous colored clay produced by this technology are calcium carbonate, talcum powder, mica powder, pottery clay, and white carbon black. In these fillers, except pottery clay, other fillers have no viscosity. Moreover, in the preparation process, these fillers are not wetted with water first, and are directly heated and melted with vaseline, paraffin, pigment and luminous powder, which is not conducive to giving full play to the role of fillers and affects the quality of luminous color clay.
