Abstract

The invention provides a preparing method of a thermoplastic elastomer environment-friendly basketball leather, which includes the following steps: applying hot melt adhesive to a base fabric, heating and melting a thermoplastic elastomer and a modifying agent to be adhered to the treated base fabric; mixing the thermoplastic elastomer and a foaming agent to be heated and melted into a foaming body, and the foaming body is adhered to the product; and mixing the thermoplastic elastomer and a coloring agent to be adhered to the product and pressed and cooled through a press roll with ball leather pattern, so as to make the thermoplastic elastomer environment-friendly basketball leather. The method avoids the solvent during the production process, has no influence and pollution on the environment, and adopts the environment-friendly material as the raw material. The basketball leather prepared through the preparing method has flexible surface, excellent hand feel and high elasticity, and is corrosion-resistant, ageing-resistant and hydrolysis-resistant.

Description

technical field [0001] The invention relates to a preparation method of synthetic leather, in particular to a preparation method of thermoplastic elastomer environment-friendly basketball leather. Background technique [0002] With the improvement of people's living standards, the improvement of physical fitness is closely linked with health, and various sports are entering people's lives. Most of them have put forward higher requirements for the quality of sports balls. Basketball is a common sport among people. At present, there are genuine leather and imitation leather, and ball leather made of polyvinyl chloride (PVC) and polyurethane (PU) is widely used in the market. They have sulfides, chlorides, complex compounds, phthalates, and DMF wastewater and waste gas emissions during the production process. Although people have already recycled them, it is difficult to meet the requirements of environmental protection and cause great harm to people. Contents of the inventi...
