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 softclay 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.
