Problems solved by technology

The skin of traditional basketball (such as traditional rubber vulcanized basketball) is not only dull in color, but also has poor weather resistance. With the change of climate and time, the basketball is easy to deform and its skin is easy to crack and become brittle; in addition, the safety of traditional basketball is poor , the skin is not soft enough, the user will feel particularly painful when being hit by a ball during use

preparation example Construction

[0029] The preparation method of described ball epidermis, it comprises the following processing steps:

[0030] (1) Preparation of SBR / EVA blend: the weighed styrene-butadiene rubber and ethylene-vinyl acetate copolymer are melt-mixed to obtain the SBR / EVA blend;

[0031] (2) Prepare the main rubber: add the SBR / EVA blend, reinforcing filler and accelerator obtained in step (1) into the internal mixer and mix to obtain the main rubber;

[0032] (3) preparing the ball skin material: adding the main rubber, foaming agent and vulcanizing agent obtained in step (2) into an open mill and mixing to obtain the ball skin material;

[0033] (4) The ball skin material obtained in step (3) is extruded, calendered, and cut to obtain the ball skin.

[0034] Wherein, the specific operation method of step (1) is: set the temperature on the surface of the double rollers of the open plastic mixer to 50-70°C, and then mix the styrene-butadiene rubber and ethylene - Put the vinyl acetate copo...

Abstract

The invention relates to a ball skin material and a method for preparing the ball skin. The ball skin material comprises the following components in parts by weight: 30-40 parts of SBR / EVA blend, 40-60 parts of reinforcing filler, 0.2-0.8 parts of vulcanizing agent, 0.5-1.0 parts of accelerator, 2-4 parts of foaming agent; wherein, the SBR / EVA blend includes styrene-butadiene rubber and ethylene-vinyl acetate copolymer, and styrene-butadiene rubber and ethylene-acetic acid The weight ratio of the ethylene copolymer is 1:0.2~1. The ball skin made of the ball skin material of the present invention has excellent weather resistance and wear resistance. Even with the change of climate and time, the properties of the ball skin still change. There will be too much variation, so that the ball made of the skin material is not easily deformed and is not prone to cracking, embrittlement and cracking.

Description

technical field [0001] The invention relates to a ball skin material and a preparation method thereof. Background technique [0002] As a large category of sports, ball games are increasingly favored by people, including basketball, football, volleyball, rugby, etc., especially basketball and football have become more and more popular among school students, and corresponding regulations have been set up. teaching courses. [0003] Taking basketball as an example, most basketballs are mainly composed of an inner tube, a yarn wrapping layer, a middle tire layer and a skin covering the periphery of the middle tire layer from the inside to the outside. Of course, the ball is also equipped with a ball nozzle. The skin of traditional basketball (such as traditional rubber vulcanized basketball) is not only dull in color, but also has poor weather resistance. With the change of climate and time, the basketball is easy to deform and its skin is easy to crack and become brittle; in ...
