[0031] The preparation method of the fetal skin in the ball, which includes the following process steps:

[0032] (1) Preparation of SBR / EVA blend: a good butadiene rubber is melt mixed with ethylene-vinyl acetate copolymer;

[0033] (2) Preparation of principal glue: SBR / EVA blend, reinforcing filler, and accelerators obtained by step (1) are mixed into the masonry, and the main glue is obtained.

[0034] (3) Preparation of the tetum material in the preparation of the tires: the main glue, foaming agent, and sulfurization agent obtained by step (2) are added to the opening mill, and the tumulative skin material is obtained.

[0035] (4) Step (3) The ball in the ball is extruded, caulced, cut, and then the ball is obtained in the skin.

[0036] Among them, the specific operation method of step (1) is: set the temperature of the double roller surface of the open plastic machine to 50-70 ° C, which will be referred to as a good butyrene rubber, ethylene-vinyl acetate copolymer t...

Abstract

The invention relates to a tire-in-ball skin material and a method for preparing the tire-in-ball skin material. The tire-in-ball skin material comprises the following components in parts by weight: 30-50 parts of SBR / EVA blend, reinforcement 30-60 parts of filler, 0.5-1.0 parts of vulcanizing agent, 0.8-1.2 parts of accelerator, 1-3 parts of foaming agent; wherein, the SBR / EVA blend includes styrene-butadiene rubber and ethylene-vinyl acetate copolymer, and The weight ratio of styrene-butadiene rubber to ethylene-vinyl acetate copolymer is 1:0.1~0.3. The tire-in-ball skin made of this tire-in-ball skin material has excellent weather resistance and wear resistance, even with the weather and The properties of the skin of the tire in the ball will not change much over time. In addition, the skin of the tire in the ball of the present invention is soft and has good flexibility and impact resistance.

Description

Technical field [0001] The present invention relates to a method of preparing a tumulating surface skin material in a ball and a preparation of a ball in a ball. Background technique [0002] As a large class in sports, the ball movement is increasingly favored by people, including basketball, football, volleyball, football, etc., especially the sports of basketball and football in school students have become more and more popular, and set up Corresponding teaching courses. [0003] Taking basketball as an example, most basketball is mainly mainly linen, wrapped in the yarn, and the medium layer (in the prior art, in the prior art, in the prior art, the medium fetus is in the prior art, in the prior art, in the prior art The tumor surface skin is composed, and the medium in the prior art is substantially referred to as the middle tetrae) and the basketball epidermis coated in the periphery of the medium layer, and of course, the ball is also provided with a nozzle. Among them, th...
