Problems solved by technology

The outer skin of traditional rubber basketball 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 embrittle, and its wear resistance is poor. After a period of use, the surface is easy to wear, The service life of the basketball is reduced; in addition, when the player is playing, the palms will produce a lot of sweat, and the hands with sweat will affect the sense of touch (such as sticky hands, etc.) when grasping or patting the basketball, thereby affecting play with mobilization

preparation example Construction

[0020] A kind of preparation method of described rubber basketball skin, it comprises the following processing steps:

[0021] Step (1) preparing a water-absorbing resin solution: mixing sodium polyacrylate, polyurethane adhesive and water and heating to obtain a water-absorbing resin solution;

[0022] Step (2) prepares modified attapulgite;

[0023] Step (3) preparing rubber compound: after mixing the water-absorbing resin solution obtained in step (1) with natural rubber, butadiene rubber and polyethylene glycol, adding it to an internal mixer for mixing to obtain the rubber compound;

[0024] Step (4) preparation of the main glue: add the rubber compound, carbon black, zinc oxide, modified attapulgite, N,N-nickel di-n-butyldithiocarbamate, and accelerators obtained in step (3) to the internal mixer Medium mixing, winner glue;

[0025] Step (5) preparing the rubber basketball skin material: adding the main rubber, foaming agent and sulfur obtained in the step (4) into an ...

Embodiment 1

[0041] A rubber basketball skin, which is prepared from the following raw materials: 10kg of natural rubber, 60kg of butadiene rubber, 2kg of sodium polyacrylate, 5kg of polyurethane adhesive, 5kg of water, 15kg of polyethylene glycol, 15kg of carbon black, 20kg of zinc oxide, modified Attapulgite 10kg, N,N-nickel di-n-butyldithiocarbamate 0.5kg, sulfur 0.2kg, accelerator 1kg, foaming agent 2kg.

Abstract

The invention relates to a rubber basketball skin and a preparation method thereof. The rubber basketball skinis prepared from the following raw materials in parts by weight: 10-20 parts of natural rubber, 40-60 parts of butadiene rubber, 2-5 parts of sodium polyacrylate, 3-5 parts of polyurethane adhesive, 2-5 parts of water, 10-15 parts of polyethylene glycol, 15-20 parts of carbon black, 15-20parts of zinc oxide, 10-20 parts of modified attapulgite, 0.5-0.8 part of N, N-di-n-butyl nickel dithiocarbamate, 0.2-0.8 part of sulfur, 1-1.2 parts of an accelerant, and 2-4 parts of a foaming agent. The rubber basketball skin has excellent weather resistance, wear resistance and scratch resistance, in addition, the basketball skin has good water absorption performance, sweat in the palm of a user can be absorbed in time, and excellent touch feeling is brought to the user.

Description

technical field [0001] The invention relates to a rubber basketball skin and a preparation method thereof. Background technique [0002] From the inside to the outside, the rubber basketball is mainly composed of an inner tube, a yarn wrapping layer, a middle tire layer, and an outer skin covering the periphery of the middle tire layer. Of course, the ball is also equipped with a ball nozzle. The outer skin of traditional rubber basketball 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 embrittle, and its wear resistance is poor. After a period of use, the surface is easy to wear, The service life of the basketball is reduced; in addition, when the player is playing, the palms will produce a lot of sweat, and the hands with sweat will affect the sense of touch (such as sticky hands, etc.) when grasping or patting the basketball, thereby affecting Play with mobilization.
