Abstract

The invention discloses a mildew-proof antibacterial synthetic leather pulp and a preparation method thereof. The synthetic leather pulp comprises the following raw materials in parts by weight: 65-70 parts of PVC resin powder, 30-35 parts of thermoplastic polyurethane elastomer rubber, 2.0-2.5 parts of 2-n-octyl-4-isothiazolin-3-ketone, 3.5-4.5 parts of melamino-formaldehyde resin, 1-3 parts of simethicone, 0.4-0.5 part of monoglyceric stearate, 0.5-0.7 part of corn fiber,4-7 parts of peanut leaves, 28-30 parts of aluminum oxide powder, 5-8 parts of tetraethyl orthosilicate and 65-70 parts of dimethyl formamide. The synthetic leather pulp provided by the invention has the advantages of light weight, wear resistance and the like; the raw materials are easily accessible; the raw materials are mixed with antimicrobial substances, so that the pulp has the advantages of bacterium resistance, mildew resistance, deinsectization and the like; through modification of the peanut leaves, the viscidity of the peanut leaves is increased, the viscosity of the pulp is enhanced, and the performance stability of the pulp is improved.

Description

technical field [0001] The invention relates to a slurry for artificial leather, in particular to a mold-proof and antibacterial 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 th...
