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
Attapulgite-modified PVC synthetic leather has the advantages of excellent hydrolysis resistance, wear resistance, scratch resistance, and flame retardancy, but there are problems in product quality

Abstract

The invention discloses attapulgite-modified polyvinyl chloride (PVC) synthetic leather. The attapulgite-modified PVC synthetic leather comprises a surface layer, a foamed layer, a bonding layer and a brushing fabric, and is characterized in that the surface layer is prepared by mixing the following raw materials in parts by weight to form slurry: 70 to 80 parts of SG-2 type PVC resin, 30 to 40 parts of SG-5 type PVC resin, 10 to 15 parts of triethyl citrate, 30 to 35 parts of epoxy butyl oleate, 20 to 25 parts of n-butyl methacrylate, 5 to 6 parts of PVC color paste, 1 to 2 parts of dibasic lead phosphate, 1 to 2 parts of tribasic lead sulfate and 5 to 10 parts of modified diatomite. Through the improvements of the formula and the process, the flexibility of the synthetic leather is improved, and the synthetic leather has a natural comfortable hand feeling similar to that of natural leather and is difficult to damage or tear after being used for 3 to 5 years.

Description

Technical field [0001] The invention belongs to the technical field of chemical synthetic leather fabric processing, in particular to an attapulgite modified polyvinyl chloride synthetic leather and a manufacturing method thereof. Background technique [0002] At present, polyvinyl chloride synthetic leather modified by polyurethane and attapulgite is widely used in the furniture fields such as commercial furniture and household furniture. Polyurethane synthetic leather has the advantages of high simulation and good hand feeling, and has been widely favored by the market. However, a large number of DMF solvents with certain toxicity and volatility are used in the manufacturing process. Even after sufficient drying, DMF will have a large amount of residues, which becomes a source of excessive indoor air VOC pollution. At the same time, polyurethane synthetic leather is resistant to hydrolysis, Insufficient weather resistance and other issues limit its further widespread applicati...
