Abstract

The invention discloses degradable automobile leather and a preparation method thereof. The degradable automobile leather comprises a leather base layer and a coating agent applied to the leather base layer. The degradable automobile leather is characterized in that the leather base layer is a non-woven fabric subjected to slurry applying treatment, and the non-woven fabric is obtained by conducting cotton blending on soybean fiber, polyester fibers and nylon fibers; slurry used for slurry applying is prepared from water, waterborne polyurethane resin, bagasse-cassava starch polylactic acid, methylene bis-stearamide, butyl stearate, sodium carboxymethyl starch, an SP type demulsifying agent, lauryl dimethyl amine oxide, glycine betaine, N,N'-dinitrosopentamethylene tetraamine, dialkyl dithio zinc phosphate, vinyl trimethoxy silane, polyvinyl alcohol and sodium pyrophosphate; the coating agent is a casein coating agent. The leather is degradable, good in environmental friendliness and high in antistatic property, oxidation resistance, corrosion resistance, surface elasticity and surface tenderness.

Description

technical field [0001] The invention belongs to the field of leather, in particular to a degradable automobile leather and a preparation method thereof. Background technique [0002] At present, the existing automobile leather uses non-woven fabrics of chemical synthetic fibers as the base, which is difficult to degrade and easily pollutes the environment. During the coating process, the penetration and stability between the coated slurry and the base layer are poor, resulting in poor antibacterial and corrosion resistance of the automobile leather during use, and the antistatic performance of the applied automobile cannot meet the requirements. Require. Contents of the invention [0003] The invention provides a degradable automobile leather and a preparation method thereof to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A degradable automobile leather, comprising a leather base and a...
