Abstract

The invention discloses diatomite modified polyvinyl chloride synthetic leather. The diatomite modified polyvinyl chloride synthetic leather comprises a surface layer, a foaming layer, a bonding layer and a brushing fabric and is characterized in that the surface layer is manufactured by blending the following raw materials in parts by weight into slurry: 40-50 parts of SG-1 type PVC (Polyvinyl Chloride) resin, 70-80 parts of SG-6 type PVC resin, 15-20 parts of sebacic acid propylene glycol polyester, 10-15 parts of acetyl triethyl citrate, 20-25 parts of di-n-butyl maleate, 5-6 parts of PVC color paste, 1-2 parts of imarcaptoacetate dioctyltin, 1-2 parts of dibasic lead phosphate, 1-2 parts of zinc stearate, 5-10 parts of nanometer calcium carbonate and 15-20 parts of modified attapulgite. Through an improvement of a formula and a technology, the flexibility of the synthetic leather is increased, and the diatomite modified polyvinyl chloride synthetic leather has the natural comfortable hand feel similar to that of natural leather and is not easily damaged or torn.

Description

technical field [0001] The invention belongs to the technical field of chemical synthetic leather fabric processing, in particular to a diatomite-modified polyvinyl chloride synthetic leather and a manufacturing method thereof. Background technique [0002] At present, polyvinyl chloride synthetic leather modified by polyurethane and diatomaceous earth is 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...
