Polished anti-corrosion synthetic leather slurry and preparation method thereof

Abstract

The invention discloses polished anti-corrosion synthetic leather slurry and a preparation method thereof. The polished anti-corrosion synthetic leather slurry comprises the following raw materials in parts by weight: 55-60 parts of SG-6 PVC resin, 60-80 parts of polyurethane resin, 4-6 parts of protein powder, 4.5-5.5 parts of zinc oxide, 5-7 parts of manganese dioxide, 10-12 parts of silicon carbide, 8-10 parts of groundnut leaves, 1-3 parts of dimethyl silicone oil, 2-3 parts of metaphosphoric acid, 0.4-0.6 part of butyl acetate, 1-1.5 parts of p-hydroxybenzoic acid, 0.4-0.6 part of N,N'-methylene bisacrylamide, 0.5-1.0 part of ammonium persulfate, 2-4 parts of epoxy chloropropane, 3-4 parts of citric acid, 0.3-0.5 part of coco fatty acid diethanol amide, 1-2 parts of sulfosalicylic acid and 40-50 parts of methyl isobutyl ketone. The slurry disclosed by the invention is simple in preparation method, and wide in raw material source; ammonium persulfate is adopted as an oxidant, so that the slurry is good in polishing effect when being prepared into synthetic leather; the obtained synthetic leather is shining and smooth in surface; the mirror surface polishing effect can be achieved; the polished anti-corrosion synthetic leather slurry is green and environmentally friendly; through modification on the groundnut leaves, the viscosity of the groundnut leaves can be improved; manganese dioxide and silicon carbide are added, so that the viscosity of the slurry can be enhanced, and performance stability of the slurry is improved.

Description

technical field [0001] The invention relates to a slurry for artificial leather, in particular to a polishing anticorrosion 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 eff...
