Benefits of technology
The present invention provides a composite ball with high wear resistance and waterproofness. This is achieved by altering the structure of conventional balls by adding a bladder layer, an attached sheet layer, and a protective layer. The protective layer is made of thermoplastic elastic material and is molded onto the attached sheet layer. The integrity of the ball is high, and the assembly method is efficient. Additionally, the protective layer has special waterproof and wear-resisting properties. The production process is optimized, resulting in quicker and more efficient production.
Problems solved by technology
Although leather has certain wear resistance, in a high-intensity game or a court game with poor environment, the surface strength of leather balls cannot meet use requirements, and the wear speed of balls is high.
Moreover, as conventional balls are usually formed by directly splicing or sewing multiple ball pieces on a bladder, the process is complex, waterproofness is poor, and the ball pieces are easy to break and shed after repeated use, affecting the service life.

The present invention provides a composite ball with high wear resistance and waterproofness, which comprises a bladder layer, an attached sheet layer, and a protective layer, the bladder layer comprises a solid ball filled with an elastic material, the attached sheet layer comprises an upper attached sheet layer and a lower attached sheet layer, and the attached external surfaces of the upper attached sheet layer and the lower attached sheet layer are also covered by the protective layer which is molded by injecting the elastic material. As the present invention adopts the injection molding method to form the protective layer on the surface of the attached sheet layer, the present invention has special waterproof and wear-resisting properties in comparison with conventional balls.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to the field of sports goods, and in particular to a composite ball with high wear resistance and waterproofness.[0002]At present, ball games have the reputation of “the No. 1 sport in the world”, and are individual sports with highest influence on the global sports circles.[0003]In the prior art, leather is adopted normally to produce ball products. Although leather has certain wear resistance, in a high-intensity game or a court game with poor environment, the surface strength of leather balls cannot meet use requirements, and the wear speed of balls is high. Moreover, as conventional balls are usually formed by directly splicing or sewing multiple ball pieces on a bladder, the process is complex, waterproofness is poor, and the ball pieces are easy to break and shed after repeated use, affecting the service life. Now, a composite ball with high wear resistance and waterproofness which can solve the above problems is n...
