Anti-aging synthetic leather slurry and preparation method thereof

Abstract

The invention discloses anti-aging synthetic leather slurry and a preparation method thereof. The anti-aging synthetic leather slurry is prepared from the following raw materials in parts by weight: 45-50 parts of polyamide resin, 45-60 parts of water soluble phenol-formaldehyde resin, 15-19 parts of tetramethyl orthosilicate, 4-5 parts of carbon black powder, 6-8 parts of peanut leaves, 1.0-1.5 parts of polymethylsiloxane, 0.7-0.9 part of butyl benzoin ether, 0.2-0.4 part of tributyl phosphate, 0.4-0.5 part of calcium maleate, 24-26 parts of nanoscale silicon dioxide, 0.9-1.0 part of a crosslinking agent TAC, 4-5 parts of 3-aminopropyl trimethoxy silane and 60-70 parts of butoxyethoxyethyl acetate. The slurry disclosed by the invention is simple in formula and the prepared slurry can be used for effectively preventing and alleviating a high molecular material from light aging effect so as to enhance the anti-violet and anti-oxidizing performances of the slurry. Moreover, by improving the peanut leaves, the viscidity of the peanut leaves can be improved, so that the vicidity of the slurry is enhanced and the stable performance of the slurry is improved.

Description

technical field [0001] The invention relates to a slurry for artificial leather, in particular to an antiaging synthetic leather slurry and a preparation method thereof. Background technique [0002] Polyurethane synthetic leather has the characteristics of soft and natural luster, soft hand feeling, strong leather feeling, flex resistance and anti-aging, etc. It is the most ideal substitute for natural leather and is widely used in clothing, shoemaking, bags, furniture and other industries However, the polyurethane synthetic leather on the market is far from natural leather in terms of moisture permeability and wear resistance. Polyurethane synthetic leather products with poor moisture permeability will make people feel stuffy and cold. The properties of synthetic leather sizing are improved, but the process of changing the moisture permeability and wear resistance of polyurethane synthetic leather sizing is relatively complicated, the cost is high, and the effect is not ob...
