Abstract

The invention discloses an improved toy shell material. The improved toy shell material is prepared from a component A and a component B, and the weight ratio of the component A to the component B is1:(0.8-1.2), wherein the component a comprises the following components in percentage by mass: 18-22% of ethylene vinyl acetate (EVA), 2-4% of zinc stearate and 74-80% of calcium carbonate, and the component B comprises the following components in percentage by mass: 58-62% of calcium carbonate, 12-18% of a lubricant and 20-30% of EVA. The invention further discloses a preparation method of the improved toy shell material. The toy shell material can be easily cracked by pushing, a packaged finished product is not easily cracked in a transportation process, sharp points or edges are avoided after the shell material is broken, and thus children are prevented from being scratched.

Description

technical field [0001] The invention relates to a toy shell material, in particular to an improved toy shell material and a preparation method thereof. Background technique [0002] Toy eggshell is a toy that allows children to experience the egg hatching process. It is very mysterious and can fully stimulate children's desire to explore. The toy eggshell is sealed and packaged before hatching. When hatching, it needs to hatch for more than 10 minutes (that is, the doll inside the eggshell pushes the inner wall of the eggshell with external force), so that the outer shell of the toy eggshell gradually breaks, revealing the inside Hiding figure. However, the toy shell material in the prior art has the following disadvantages: it is difficult to push the top, and the shell cannot be broken for half an hour after pushing the top, and it is easy to burst when doing a simulated transportation test. The fragments after bursting are sharper and easily scratched by children. Cont...
