Problems solved by technology

They have sulfides, chlorides, chromium compounds, phthalates, DMF waste water and waste gas emissions in the production process. Although people have been recycling them, it is difficult to meet the requirements of environmental protection and cause great harm to people.
Moreover, volleyball leather usually has high production cost, complicated process, and is difficult to process. At present, volleyball leather is made by embossing the surface of ordinary PU leather. slips off easily after volleyball

Abstract

The invention provides a high-acerbity volleyball leather and a preparation method thereof. The volleyball leather sequentially comprises: a base cloth; a PU layer comprising, by weight, 80-100 partsof PU, 1-6 parts of wood powder, 5-10 parts of a color paste, 0.5-3 parts of a stabilizer and 40-55 parts of a solvent; and an acerbic finishing layer from bottom to top. The preparation method of thehigh-acerbity volleyball leather has the advantages of simplicity, controllability, good repeatability, and obtaining of a volleyball leather material with excellent performances, and the volleyballleather product prepared through the method has the advantages of soft surface, high acerbity, excellent elasticity, good hand feeling, good wearing resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of preparation of synthetic leather, in particular to a volleyball leather with high astringency and a preparation method thereof. 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, which puts forward higher requirements for the quality of sports balls. Because of its simplicity and convenience, volleyball has become more and more popular among people. At present, the materials of volleyball include genuine leather and imitation leather, and the ball leather made of polyvinyl chloride (PVC) and polyurethane (PU) is widely used in the market. They have sulfides, chlorides, chromium 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 en...
