Resin sporting ball and preparation method thereof

Abstract

The invention relates to a sporting ball, and provides a resin sporting ball which can shine in a dark environment and is excellent in surface abrasion resistance, high in overall stability and good in physical and mechanical performances. The resin sporting ball is prepared from the following raw materials in parts by weight: 780-820 parts of macromolecular unsaturated polyester resin, 8-12 parts of noctilucent powder, 2-3 parts of colorful noctilucent powder, 200-220 parts of agate powder, 2-3 parts of a curing agent, 0.8-1.2 parts of a dryer, 0.2-0.3 part of a color concentrate, 5-7 parts of an edible oil and 2-3 parts of a defoaming agent. Meanwhile, the invention provides a preparation method of the resin sporting ball. The preparation method comprises the following preparation steps: (1) preparing the materials; (2) mixing; (3) defoaming in a vacuum manner; (4) adding the color concentrate; (5) transferring to a mold; (6) demolding after forming, and naturally air-drying.

Description

Technical field [0001] The invention relates to a sports ball, in particular to a resin sports ball and a preparation method thereof. Background technique [0002] Existing sports balls are generally divided into two types, one is an inflatable type, the other is a non-inflatable type, an inflatable sports ball, which needs to be filled with gas at an appropriate pressure during use. The hard elasticity is too large, the inflation is insufficient, and the soft elasticity of the ball surface is insufficient. The inflatable structure of the ball is not easy to grasp how much the amount of inflation should be, which makes the performance of the ball relatively unstable, and the ball of this structure is prone to air leakage, which affects the use. With the continuous development of sports, in certain ball sports, the performance of inflatable sports balls has not kept up with the needs of the development of the project. Therefore, people have developed non-inflatable balls, but the...

AI Technical Summary

Problems solved by technology

[0002] Existing sports balls are generally divided into two types, one is an inflatable type, and the other is a non-inflatable type. Inflatable sports balls need to be filled with gas of appropriate pressure during use. The hard elasticity is too large, the inflation is insufficient, and the surface of the ball is not soft enough

Balls with an inflatable structure are not easy to know how much to inflate, which makes the performance of the ball less stable, and the ball with this structure is prone to air leakage, which affects the use

With the continuous development of sports, in some ball games, the performance of inflatable sports balls has not kept up with the needs of project development. Therefore, people have developed non-inflatable balls, but the surface elasticity of this ball is relatively low. Poor, the density of the sphere is relatively uneven, it cannot move in a straight line when moving, the overall stability is poor, it is not wear-resistant, and it does not emit light in a dark environment, and the physical and mechanical properties are generally poor
