Problems solved by technology

However, some properties of PU synthetic leather are far inferior to natural leather. For example, natural leather has good water absorption and air permeability, while the nature of PU synthetic leather itself makes it easy to form a dense film, and the water absorption and air permeability are limited. The simulation of synthetic leather Performance, comfort and quality are difficult to improve

Abstract

The invention discloses a tea saponin-containing PU synthetic leather which is produced from the following raw materials in parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 2-4 parts of tea saponin, 0.5-1 part of soluble soybean polysaccharide, 1-2 parts of liquid rosin resin, 0.1-0.2 part of squalane, 1-2 parts of talcum powder, 1-2 parts of bamboo charcoal powder, 4-8 parts of mill base, 5-10 parts of sodium carboxymethylcellulose, 0.2-0.4 part of sodium salicylate, 0.5-1 part of aluminum chloride and 2-4 parts of a performance additive. The synthetic leather disclosed by the invention is added with a natural non-ionic surface active agent tea saponin, the quality and the ageing resistance of the synthetic leather are improved, and the natural non-ionic surface active agent tea saponin also has auxiliary functions of preventing mould and resisting bacteria, resisting oxidation, and killing and expelling insects.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to PU synthetic leather containing tea saponin and a production method thereof. Background technique [0002] PU synthetic leather belongs to polyurethane elastomer, which is similar to natural leather in structure, and has the advantages of good appearance texture, strong mechanical properties, low price, and convenient processing. It has a wide range of applications and a large number of types, and is an ideal material to replace natural leather. , At present, it has largely replaced natural leather with insufficient resources. However, some properties of PU synthetic leather are far inferior to natural leather. For example, natural leather has good water absorption and air permeability, while the nature of PU synthetic leather itself makes it easy to form a dense film, and the water absorption and air permeability are limited. The simulation of synthetic leather Sex, comfort and...
