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
The present invention relates to synthetic leather field, be specifically related to a kind of PU synthetic leather containing Tea Saponin and production method thereof.
Background technology
PU synthetic leather belongs to polyurethane elastomer, from the approximate natural leather of structure, and possess the advantages such as appearance tactile impression is good, mechanical performance is strong, cheap, easy to process, its applied range, kind quantity are various, be the material replacing natural leather ideal, replace the natural leather of inadequate resource at present in a large number.But the partial properties of PU synthetic leather can not show a candle to natural leather, as natural leather has good water imbibition, gas permeability, and the character of PU synthetic leather itself causes it easily to form fine and close film, water suction, permeability are restricted, and the emulation of synthetic leather, comfort level and quality are difficult to improve.
Tea Saponin has another name called TS, is by the class glycoside compound extracted in tea tree seed, is a kind of natural non-ionic surface active agent of good performance.Tea Saponin has good emulsification, dispersion, foaming, the function such as moistening, and has the effects such as antimildew and antibacterial, anti-oxidant, desinsection expelling parasite.At present, Tea Saponin product has been widely used in washing, the fields such as wool spinning, knitting, medical, daily-use chemical industry industry.
