Abstract
The invention discloses a method for producing attapulgite soft clay. Key points of the technical scheme comprise the following steps of: adding a sand-grain attapulgite mixture into an operating horizontal flour mixing machine, slowly adding solution of sodium polyacrylate gel into the sand-grain attapulgite mixture and stirring so as to obtain a clod-shaped attapulgite mixture; and spraying methyl silicone oil onto the clod-shaped attapulgite mixture, kneading the clod-shaped attapulgite mixture into semi-finished attapulgite soft clay, pressing the semi-finished attapulgite soft clay into flat-plate attapulgite soft clay, sealing and packaging so as to obtain a finished product. The attapulgite soft clay has high viscosity, softness and plasticity and small contractibility rate, becomes hard after natural drying, does not need baking, does not crack and has no corrosion and greasy handfeel. After different colors are added into the attapulgite soft clay, a plurality of colored soft clay can be produced and handicraft articles with clear patterns, bright colors and vivid effects can be made by using attapulgite soft clay with different colors. The attapulgite soft clay is suitable for molding patterns, molds and handicraft articles.
Description
Technical field
The present invention relates to the mud of making pottery, be specifically related to a kind of production method of Attapulgite soft ceramic mud.
Background technology
The main raw material of soft ceramic mud is polyvinyl chloride and lime carbonate, binding property is bad under the normal temperature state, prolonged preservation easily wears out and fades, bubble easily during the baking soft ceramic mud,, finished product is burnt and melt if when temperature surpasses 200 ℃, even may cause burning, generate chloride pungency toxic smog, the selling price of soft ceramic mud is higher, is unfavorable for promoting the use of.
The Chinese patent publication number is: CN 101186736, open day: on May 28th, 2008, name is called " a kind of soft ceramic mud and preparation method thereof ", disclose: " a kind of soft ceramic mud and preparation method; it is prepared from by following parts by weight of component: polyvinyl chloride (PVC) paste resin 15～40, bizinc resin 20～55, lime carbonate 15～35, softening agent 0.1～0.4, toner 0.5～0.15, all the other are micro-moisture and impurity ".
The weak point of above-mentioned patent is that the soft ceramic mud main raw material that this technology is produced is polyvinyl chloride (PVC) paste resin, bizinc resin and lime carbonate, and binding property is bad under the normal temperature state, is unfavorable for making moulding, and bizinc resin belongs to dangerous product.
