Problems solved by technology

However, a large amount of DMF solvent with certain toxicity and volatility is used in its manufacturing process, and there will be a large amount of residual DMF even after sufficient drying, which becomes a source of excessive VOC pollution in indoor air; at the same time, polyurethane synthetic leather is resistant to hydrolysis, Insufficient weather resistance and other issues limit its further wide application
Polyvinyl chloride synthetic leather for sports shoes has the advantages of excellent hydrolysis resistance, abrasion resistance, scratch resistance, flame retardancy, etc., but there are problems in product quality

Abstract

The invention discloses a polyvinyl chloride (PVC) synthetic leather for sports shoes. The polyvinyl chloride synthetic leather comprises a surface layer, a foaming layer, an adhering layer, and a brushing fabric, and is characterized in that the surface layer is prepared from the following raw materials in parts by weight: 40-50 parts of SG-1 type PVC resin, 70-80 parts of SG-6 type PVC resin, 30-35 parts of hexanedioic acid propylene glycol polyester, 25-30 parts of n-butyl methacrylate, 15-20 parts of sebacic acid propylene glycol polyester, 5-6 parts of PVC color paste, 1-2 parts of bis(isooctyl thioglycolate) dioctyldllauryltin, 1-2 parts of calcium stearate, 1-2 parts of dimethyl bis(isooctyl thioglycolate) and 5-10 parts of modified attapulgite. The PVC synthetic leather is increased in flexibility through the improvement of a formula and a process, has a natural comfortable hand feel similar to a natural leather, is not easily broken or torn and damaged after 3-5 years, and is suitable for being used as a fabric of the sports shoes.

Description

technical field [0001] The invention belongs to the technical field of chemical synthetic leather fabric processing, in particular to polyvinyl chloride synthetic leather for sports shoes and a manufacturing method thereof. Background technique [0002] At present, polyurethane and PVC synthetic leather for sports shoes are widely used in commercial furniture and household furniture. Polyurethane synthetic leather has the advantages of high imitation and good hand feeling, and has been widely favored by the market. However, a large amount of DMF solvent with certain toxicity and volatility is used in its manufacturing process, and there will be a large amount of residual DMF even after sufficient drying, which becomes a source of excessive VOC pollution in indoor air; at the same time, polyurethane synthetic leather is resistant to hydrolysis, Insufficient weather resistance and other problems limit its further wide application. Polyvinyl chloride synthetic leather for spo...
