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
The twist-resistant PVC synthetic leather has excellent hydrolysis resistance, abrasion resistance, scratch resistance, flame retardant and other advantages, but there are problems in product quality

Abstract

The invention discloses twist-resisting polyvinyl chloride synthetic leather which comprises a surface layer, a foaming layer, a bonding layer and fluffing cloth. The twist-resisting polyvinyl chloride synthetic leather is characterized by being prepared from the following components in parts by weight: 50-60 parts of SG-2 PVC (Polyvinyl Chloride) resin, 30-40 parts of SG-6 PVC resin, 20-25 parts of isophthalic ester, 10-15 parts of phthalic polyester, 10-15 parts of trioctyl trimellitate, 5-6 parts of PVC color cream, 1-2 parts of zinc stearate, 1-2 parts of protein powder, 20-25 parts of zinc oxide, 10-15 parts of magnesium oxide, 10-15 parts of N660 carbon black, 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.

Description

technical field [0001] The invention belongs to the technical field of chemical synthetic leather fabric processing, in particular to a twist-resistant polyvinyl chloride synthetic leather and a manufacturing method thereof. Background technique [0002] At present, polyurethane and twist-resistant polyvinyl chloride synthetic leather are widely used in commercial furniture and household furniture and other furniture fields. 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.
