Abstract

The invention discloses an antipollution sofa leather making method. The method comprises the following steps: uniformly stirring 5-10 parts of dimethyl formamide with 2-10 parts of a color paste, 10-30 parts of wood powder and 1-5 parts of a surfactant; adding 80-100 parts of wet polyurethane resin and 150-280 parts of dimethyl formamide to obtain a wet material; impregnating a base fabric, ironing, drying, coating the wet material, solidifying, foaming, washing with water, and drying to obtain a wet base; uniformly mixing 80-100 parts of a polyurethane surface layer resin with 40-70 parts of an organic solvent, 0.5-2 parts of an assistant and 5-8 parts of an environmentally friendly toner to obtain a dry material; uniformly mixing 80-100 parts of a polyurethane binding resin with 20-60 parts of the organic solvent, 0.5-2 parts of the assistant and 5-8 parts of the environmentally friendly toner to obtain a binder; coating the dry material on release paper, drying, coating the binder, pasting the wet base, drying, cooling, and separating from the release paper to obtain a semi-finished product; and carrying out surface treatment to obtain a finished product. The method effectively improves the oil stain resistance of sofa leather.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making anti-pollution sofa leather. Background technique [0002] When oil is spilled on the surface of a sofa covered with ordinary sofa leather, the oil will penetrate inward, resulting in the formation of oil stains on the surface of the sofa that are difficult to wipe clean, and some corrosive oil stains on the surface of the sofa, if not cleaned in time, will This will cause aging and damage to the surface of the sofa, greatly shorten the service life of the sofa, and bring troubles to the use of the sofa. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for manufacturing anti-pollution sofa leather. The method for manufacturing anti-pollution sofa leather has a simple process, and the surface of the produced product can avoid oil stain penetration, which is convenient for quic...
