AI Technical Summary

Problems solved by technology

The existing glue for making toys mainly includes phthalate and PVC, among which PVC is the main material, and the content of phthalate is 8-12%. This kind of glue material mainly has the following disadvantages: poor stability , poor plasticity, easy to deform after being placed at room temperature for more than 6 months, and no longer has thermoplasticity, it is difficult to control the softness and hardness during preparation, and the preparation is difficult
In addition, due to the excessive proportion of phthalates in the existing enamel, this enamel material has certain toxicity and emits an unpleasant special smell

Abstract

The invention relates to vinyl for manufacturing a toy. The vinyl for manufacturing a toy is prepared from the following raw materials in percentage by weight: phthalate, dioctyl phthalate, dibasic lead stearate, PVC (polyvinyl chloride) paste resin, PVC coarse powder, PVC medium powder, talcum powder, PVC hard oil, plasticizer TXIB, acetyl-tri-n-butyl citrate, vanillin, amyl acetate, geranyl butyrate and maltol. The vinyl has good hardness, smooth handfeel, strong plasticity, high re-shaping ability and high stability, and does not deform easily after multiple extrusions; and meanwhile, the vinyl is non-toxic and harmless and has fresh fruit aroma.

Description

technical field [0001] The invention relates to a material for making toys and a preparation method of the material, in particular to a vinyl and a preparation method of the vinyl. Background technique [0002] Toys made of vinyl materials are called vinyl toys. Vinyl toys are soft toys that feel very comfortable and slippery. Existing vinyl toys are generally made in the shape of small hollow animals or fruits, which are mainly for the player to pinch and play with. Therefore, this type of toy not only requires relatively high plasticity and stability of the material, but also requires more It is not easy to deform after the first extrusion, with moderate hardness and good toughness. The existing glue for making toys mainly includes phthalate and PVC, among which PVC is the main material, and the content of phthalate is 8-12%. This kind of glue material mainly has the following disadvantages: poor stability , poor plasticity, easy to deform when placed at room temperature...
