Abstract

The invention relates to the technical field of artificial leather and provides water-wiping-resistant artificial leather and a preparation method thereof. The water-wiping-resistant artificial leather and the preparation method thereof are used for solving the problem in the prior art that the artificial leather is not resistant to water wiping and is poor in air-permeable effect. The water-wiping-resistant artificial leather comprises a base fabric layer, an adhesive layer, a foam layer and a polyurethane surface layer, wherein the adhesive layer, the foam layer and the polyurethane surface layer are sequentially arranged on the base fabric layer; an air-permeable and water-tight coating is arranged between the foam layer and the polyurethane surface layer and comprises the following raw materials in parts by weight: 60-80 parts of polyurethane, 20-40 parts of dimethylformamide, 10-15 parts of leveling agent, 10-20 parts of colored slurry and 100-120 parts of hydrogen peroxide.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a water-resistant artificial leather and a preparation method thereof. Background technique [0002] The artificial leather currently produced is usually composed of a surface layer, a foam layer, an adhesive layer and a base cloth layer. For the purpose of improving the surface gloss, smoothness or flexibility of the artificial leather, the surface of the artificial leather (that is, the surface of the surface layer) ) is generally treated with a surface treatment agent. Concretely, a kind of preparation method of existing artificial leather is provided as follows, including: Step 1, select base cloth and release paper, prepare polyvinyl chloride surface layer slurry, polyvinyl chloride foaming slurry, polyurethane paste A mixture and a surface treatment agent, the surface treatment agent is made by mixing 100 parts by weight of an acrylic treatment agent (acrylic re...
