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
PVC synthetic leather has the advantages of excellent hydrolysis resistance, wear resistance, scratch resistance, flame retardancy, etc., but there are problems in product quality

Abstract

The invention discloses polyvinyl chloride synthetic leather, which comprises a face layer, a foaming layer, a bonding layer and a brushing fabric. The polyvinyl chloride synthetic leather is characterized in that the face layer is made of slurry prepared from the following raw materials in parts by weight: 40-50 parts of SG-1 type PVC (polyvinyl chloride), 70-80 parts of SG-6 type PVC resin, 20-25 parts of phthalate, 15-20 parts of sebacic propylene glycol polyester, 20-25 parts of n-butyl methacrylate, 5-6 parts of PVC color paste, 1-2 parts of imarcaptoacetate dioctyltin, 1-2 parts of zinc stearate, 5-10 parts of light calcium carbonate and 35-50 parts of modified attapulgite. According to the invention, through formula and process improvement, the toughness of the synthetic leather is increased, and the polyvinyl chloride synthetic leather has natural and comfortable handfeel similar to that of natural leather; and the polyvinyl chloride 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 polyvinyl chloride synthetic leather and a manufacturing method thereof. Background technique [0002] At present, polyurethane and 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. Polyvinyl chloride synthetic leather...
