Abstract

The invention relates to light color clay and a production method thereof. The production method is characterized by comprising the following steps: adding water in proportion into a reactor for stirring, slowly adding polyvinyl alcohol in proportion into the reactor for stirring, and gradually raising the temperature to fully dissolve the polyvinyl alcohol; continuing stirring, and adding a wetting agent, a defoamer, a mildewproof agent, pigment or dye for stirring; and slowly adding a light filler, and adding gel solution dropwise with stirring until the end. The light color clay comprises the following compositions: 4 to 15 portions of polyvinyl alcohol, 0.1 to 2 portions of gel, 40 to 60 portions of water, 10 to 30 portions of filler, and auxiliary materials of 1 to 2 portions of defoamer, 0 to 20 portions of wetting agent, 0.15 to 0.75 portion of mildewproof agent and proper portions of pigment or dye. The light color clay has no pulverizing, crack or hand sticking, and flexibility, can be dried in air, and can stick small articles such as paper, and dust on clothes before the drying.

Description

Technical field [0001] The invention relates to the technical field of lightweight colored clay and its production method. Background technique [0002] Chinese patent CN1245731A also mentions a method of using polyvinyl alcohol, carboxymethylcellulose and borax to make toy glue, but it does not add fillers and the system has no plasticity. Just a glue. [0003] In people's lives, children urgently need a kind of water-based colored clay. They hope that it will be dry, will not dehydrate, pulverize, or crack. It will not shrink, has excellent plasticity and a comfortable feel, and hope that it will be non-toxic. It is toxic and can be used as a cleaning material when wet to clean the surfaces of textiles, carpets and furniture to achieve a multi-purpose effect. Contents of the invention [0004] The primary technical problem to be solved by the present invention is to provide a water-based lightweight colored clay that will dry, but will not dehydrate, pulverize, crack, ...
