Problems solved by technology

[0002] As a popular sport, basketball is widely loved by everyone. However, due to technical reasons such as the use of basketball materials and manufacturing techniques, basketballs often suffer from air leakage, poor elasticity, insufficient roundness, and insufficient impact times during continuous use. etc. series
The root cause of this kind of problem is that the general production process of basketball tires is relatively messy and immature, and there is no stable and reliable production process.

Embodiment 1

[0023] A method for gluing a middle tire of a basketball, comprising the following steps:

[0024] (1) The inner tank is inflated. After the inner tank has passed the air tightness test, it is put into the standard template, and the inner tank is inflated to the diameter limited by the required standard template;

[0025] (2) Tailor the required pieces of cloth;

[0026] (3) Polish the liner clean, send it into the oven, bake it at 250°C for 30s, and let it cool down;

[0027] (4) Paste glue on the surface of the inflatable liner;

[0028] (5) Paste the cut cloth with glue for pasting.

[0029] The glue is modified phenolic resin glue.

[0030] Described modified phenolic resin glue is made up of the following raw materials of weight part:

[0031] Triethanolamine 5, phenol 110, 37% formaldehyde 140, sodium hydroxide 1, polyethylene wax 4, sucrose acetate isobutyrate 1, stearic acid 4-6, p-toluenesulfonic acid 0.02.

[0032] The preparation method of described modified ph...

Abstract

The invention discloses a sizing method for a basketball middle tire. The method comprises the steps of inflating, cloth cutting, inner tank grinding and sizing. The method firstly heats the middle tire, removes the humidity of a middle tire surface, saves a glue, and enhances the adhesive adsorption capacity of the glue; according to the glue, triethanolamine modified phenol is used as a raw material to prepare a phenolic resin glue, and the reaction of stearic acid and triethanolamine improves the surface viscosity of the glue and enhances the quality of the finished middle tire.

Description

technical field [0001] The invention belongs to the technical field of basketball, and in particular relates to a method for gluing a middle tire of a basketball. Background technique [0002] As a popular sport, basketball is widely loved by everyone. However, due to technical reasons such as the use of basketball materials and manufacturing techniques, basketballs often suffer from air leakage, poor elasticity, insufficient roundness, and insufficient impact times during continuous use. And so on series. And the root cause of this type of problem is that the general manufacturing process of the basketball middle tire is more messy and immature, and there is no stable and reliable manufacturing process. Contents of the invention [0003] The purpose of the present invention is to provide a method for gluing the middle tire of a basketball in view of the defects and deficiencies of the prior art. [0004] To achieve the above object, the present invention adopts the foll...
