Abstract

The invention relates to a light colored clay and a production method thereof, which is characterized in that: add a proportioned amount of water into a reactor, start stirring, and slowly add a proportioned amount of polyvinyl alcohol into the reactor, stir and gradually raise the temperature , can completely dissolve polyvinyl alcohol to a moderate level, then continue to stir and add wetting agent, defoamer, antifungal agent, pigment or dye, then stir and slowly add light filler, then add gelling agent solution dropwise, while stirring Add dropwise until it is completed; the components include: 4-15 parts of polyvinyl alcohol, 0.1-2 parts of gelling agent, 40-60 parts of water, 10-30 parts of filler, 1-2 parts of defoamer for auxiliary materials, 0 ~20 parts of wetting agent, 0.15~0.75 parts of antifungal agent, appropriate number of parts of pigment or dye. The lightweight color clay is non-chalking, cracking, non-sticky and soft, it can be dried in the air, before drying, it can be used to stick small items, such as paper, dust from clothes.

Description

technical field [0001] The invention relates to the technical field of lightweight colored clay and a production method thereof. Background technique [0002] Also mentioned in Chinese patent CN1245731A with polyvinyl alcohol, carboxymethyl cellulose adds the method for borax to do toy glue, but it does not add filler, and system has no plasticity. Just a glue. [0003] In people's life, children urgently need a kind of water-based color clay. I hope it will dry, and it will not be dehydrated, pulverized, cracked, and will not shrink. It has excellent plasticity and a comfortable feel. I hope it is free Toxic, it can also be used as a cleaning material to clean the surface of textiles, carpets and furniture when wet, achieving 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 color clay, which will dry, but will not be dehydrated and pulverized, cracked, a...
