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
Durable polyvinyl chloride synthetic leather for luggage has excellent hydrolysis resistance, abrasion resistance, scratch resistance, flame retardancy, etc., but there are problems with product quality

Abstract

The invention discloses polyvinyl chloride synthetic leather for a luggage. The leather comprises a surface layer, a foaming layer, a bonding layer and fluffing cloth. The surface layer is slurry prepared from the following raw materials in parts by weight: 40-50 parts of SG-3 PVC (Polyvinyl Chloride) resin, 70-80 parts of SG-5 PVC resin, 30-35 parts of glycerol triacetate, 10-15 parts of epoxidized soybean oil, 20-25 parts of glycerol triglycerate, 5-6 parts of PVC color cream, 1-2 parts of bimercapto iso-octyl acetate di-n-octyl tin, 5-10 pats of zinc oxide and 5-10 parts of modified attapulgite. Through improvement of formula and process provided by the invention, the flexibility of the synthetic leather is enhanced, and the synthetic leather has a natural and comfortable handfeel similar to that of natural leather. The synthetic leather is not easy to damage or tear within 3-5 years, and suitable for use in lug gages.

Description

technical field [0001] The invention belongs to the technical field of chemical synthetic leather fabric processing, in particular to durable polyvinyl chloride synthetic leather for bags and a manufacturing method thereof. Background technique [0002] At present, polyurethane and durable polyvinyl chloride synthetic leather for bags 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. Durable polyvinyl chloride sy...
