Abstract

The invention relates to a coating slurry used in a leather preparation process. The coating slurry is prepared from the following raw materials in parts by weight: 10-15 parts of water, 60-100 parts of water-based polyurethane resin, 110-120 parts of bagasse cassava starch polylactic acid, 2-4 parts of methylene-bis stearamide, 1-3 parts of butyl stearate, 0.2-0.5 part of sodium carboxymethyl starch, 0.5-1.0 part of SP demulsifier, 1-4 parts of lauryl dimethyl amine oxide, 0.2-0.5 part of betaine, 0.2-0.5 part of N,N'-dinitrosopentamethylene tetramine, 0.2-0.5 part of zinc dialkyl dithiophosphate, 0.2-0.5 part of EDTA (ethylene diamine tetraacetic acid), 0.3-0.6 part of 3-nitro-4-hydroxyphenylarsonic acid, 0.2-0.5 part of sodium pyrophosphate and 0.1-0.5 part of sodium acetate. The coated leather has the advantages of high antistatic property, high oxidation resistance, high corrosion resistance, high antimicrobial capacity, high surface elasticity and high surface tenderness.
