Abstract

The invention discloses a molding paste composition. The molding paste composition comprises 120-150 parts of a first solvent, 50-100 parts of a second solvent, 18-25 parts of polyvinyl alcohol, 2-3 parts of a thickening agent, 1.5-3 parts of an antiseptic, 12-15 parts of glycerol, 6-8 parts of borax and 10-15 parts of polystyrene. The invention also discloses a preparation method of the above molding paste, and a use of the molding paste in the making of toys. The molding paste has the advantages of light weight, no fluidity, formation of various shapes after extrusion under a slight pressure, no effusion, and moisture retention within a long time. The preparation method of the molding paste is economic, and the addition of the antiseptic prevents the increase of bacteria and ensures the health of children after the molding paste is used to make toys.

Description

technical field [0001] The invention relates to the field of molding paste, in particular, the invention relates to a molding paste composition with good elasticity that can be applied to children's toys, its preparation method and application. Background technique [0002] Molding paste is a new type of colloid, which is soft and plastic, and can be used in many fields, such as toys. There are few specific records of toys made of molding paste in the prior art, and the records of this product in the documents that can be retrieved are relatively rough, so there is a lot of room for research and development of this product. [0003] For example, U.S. Patent No. 5,157,063 discloses an elastic molding paste and its preparation method, which includes a hydrophilic solid gel and a polyvinyl matrix crosslinked by disodium tetraborate, and a polyvinyl matrix mixed therein. styrene. The specific composition of the elastic molding paste is not specifically disclosed in this patent...
