Toy steel ball and preparation method thereof

Abstract

The invention discloses a toy steel ball and a preparation method thereof. The toy steel ball comprises a magnetic ball body and rubber, wherein the rubber coats the surface of the magnetic ball body;the rubber is prepared from the following ingredients in parts by weight: 9990 to 10010 parts of silicon rubber, 139.98 to 140.02 parts of high-yellowing-resistant vulcanizing agents S-18, 3 to 4 parts of coloring rubber 1400, 75 to 85 parts of coloring rubber 1333 and 15 to 20 parts of coloring rubber 1924; all ingredients are sequentially added into a roller machine and are uniformly mixed to be made into the rubber; the rubber and the magnetic ball body are put into a die cavity of a mold; the temperature of the mold is regulated to 160 to 180 DEG C; and heating is performed for less than3 minutes, so that the rubber is vulcanized at high temperature and coats the outer layer of the magnetic ball body. The rubber prepared by the method cannot crack; the problem of outer layer rubber cracking of the toy steel ball is solved; meanwhile, the coloring rubber is added for controlling the colors of the toy steel ball, so that painting is not needed; the problem of paint falling of the toy steel ball is solved; and meanwhile, when the rubber collides with a labyrinth vertical plate, jarring noise cannot be generated.

Description

technical field [0001] The invention relates to a toy steel ball, and more specifically, relates to a formula of a toy steel ball and a preparation method thereof. Background technique [0002] The ball maze toy product achieves the purpose of the game by moving the balls in the path groove formed by the bottom plate and the vertical plate on the maze path element. It is interesting and exploratory, and is very popular among the public. Existing toy steel balls are generally magnetic ball bodies such as iron or steel. In order to make the surface of the toy steel ball have different colors, it is generally done by coloring the surface of the steel ball or iron ball or covering a layer of colored plastic. The toy steel ball prepared by the above method is prone to paint falling off when it hits the vertical plate when walking in the maze, which affects the aesthetics of the toy steel ball.

AI Technical Summary

Problems solved by technology

Existing toy steel balls are generally magnetic ball bodies such as iron or steel. In order to make the surface of the toy steel ball have different colors, it is generally done by coloring the surface of the steel ball or iron ball or covering a layer of colored plastic. The toy steel ball prepared by the above method is prone to paint falling off when it hits the vertical plate when walking in the maze, which affects the aesthetics of the toy steel ball. There will be noisy noise, which will affect the quality of the game; if it is used to cover the surface of toy steel balls with plastic, although the noise and paint peeling problems can be avoided, but due to the unreasonable raw materials and craftsmanship of the plastic covering the surface of toy steel balls on the market, The plastic is easy to crack, and the toy steel ball after cracking does not roll smoothly, which affects the quality of the game
