Abstract

The invention relates to the technical field of artificial leather production, and provides a preparation method of wear-resistant waterborne polyurethane artificial leather; the preparation method comprises the following steps: (1) release paper is coated with a water-based polyurethane slurry surface layer, and the water-based polyurethane slurry surface layer comprises the following components:water-based anionic polyurethane resin, water-soluble hard polyethylene wax, thickening agent hydroxypropyl methyl cellulose, a water-based cross-linking agent AKU, a water-based polyurethane flatting agent, water-based color paste, a water-based defoaming agent, peppermint oil, eucalyptus oil, 95% alcohol, bergamot oil, camphor oil and modified nano aluminum oxide; (2) the water-based polyurethane slurry surface layer is coated with a water-based polyurethane adhesive, solid spice powder and an antibacterial powder mixture; and (3) a semi-finished product is subjected to roller pressing, standing, stripping of an isolation film, spraying a hand feeling agent, and drying to obtain a finished product. According to the invention, the wear resistance of the waterborne polyurethane artificialleather is improved, and the waterborne polyurethane artificial leather has delicate fragrance and is mainly applied to clothing leather.

Description

technical field [0001] The invention relates to the technical field of artificial leather production, in particular to a preparation method of wear-resistant water-based polyurethane artificial leather. Background technique [0002] Compared with real leather, artificial leather has the advantages of low cost and high utilization rate, and its market share is increasing. my country's production enterprises basically use traditional solvent-based polyurethane resins to manufacture synthetic leather. Most of the solvents used as the dispersion medium of the resin are toxic and harmful organic solvents such as dimethylformamide, toluene, acetone, butanone, etc., and their content in the resin is as high as 70%. %-80%. These solvents cannot be completely recovered at present, not only causing environmental pollution on the product side, but also seriously endangering the health of employees during the production process. There are two types of synthetic leather currently on the...
