Problems solved by technology

[0003] Existing vinyl for making toys mainly includes phthalate and PVC, wherein PVC is the main material, and the content of phthalate is 8-12%. This vinyl material mainly has the following disadvantages: Poor stability and poor plasticity. It is 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, because of the excessive proportion of phthalates in the existing enamel, the enamel material has certain toxicity and emits an unpleasant special smell
In addition, the artificial skin of the human body prepared by the above formula has a relatively rough surface, and also has the defect of a hard hand feeling, which is far from the real skin of the human body.

Abstract

The invention discloses a vinyl formula, comprising the following components by weight percent: PVC (polyvinyl chloride) crude powder, PVC baby powder 810, a plasticizer, hard oil TXIB, hard oil 57 degrees, heat-resistant oil ED-S, a stabilizing agent CE-116 and a release agent. The vinyl prepared by the formula disclosed by the invention is good in hardness, smooth in handfeel, strong in plasticity, good in stability, and closer to a real handle of human skin.

Description

technical field [0001] The invention relates to the field of formula technology, in particular to a vinyl glue used for manufacturing toys and human simulation skin. 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. In addition to making toys, vinyl is also used to make human body simulation skin, which is used in the field of teaching. [0003] Existing vinyl for making toys mainly includes phthalate and PVC, wherein PVC is the main material, and the content of phthalate is 8-12%. This vinyl material mainly has the fo...
