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 gloves 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 polyvinyl chloride synthetic leather for gloves. 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: 70-80 parts of SG-2 PVC (Polyvinyl Chloride) resin, 30-40 parts of SG-7 PVC resin, 10-15 parts of triethyl citrate and 30-35 parts of epoxy butyl oleate. The modified attapulgite and bentonite in the formula are good in ventilating and moisture absorption conductivity, so that the synthetic leather provided by the invention meets the demand on excellent ventilating and moisture absorption function. 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 is applicable to gloves.

Description

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