Problems solved by technology

[0010] 1. The coating (that is, the coating formed on the surface of the artificial leather after the treatment agent is dried) has poor adhesion to the surface of the artificial leather, which makes the coating easy to crack and fall off;
[0011] 2. Not resistant to water rubbing: that is, when the artificial leather is wiped with a damp cloth, foam will appear on the surface of the artificial leather, which is not easy to clean;
[0012] 3. The surface gloss is poor, the hand feeling is not smooth enough, and the wear resistance is poor. The number of times measured by the Martindale wear test can only reach about 5000 times

Abstract

The invention relates to water-scrubbing resistant artificial leather and a preparation method thereof. The artificial leather comprises a surface layer, a foaming layer, an adhesion layer and a base cloth layer, wherein the surface of the surface layer is coated with a coating; the surface layer is formed by drying slurry on a polyurethane surface layer; the coating is formed by drying a surface treating agent; the surface treating agent comprises polyurethane resin, an organic solvent, a neutralizing agent and a leveling agent. The preparation method of the artificial leather comprises the following steps: sequentially forming the polyurethane surface layer, the foaming layer, the adhesion layer and the base cloth layer on release paper; removing the release paper to obtain a semi-finished product of artificial leather; applying the prepared surface treating agent to the surface of the semi-finished product of artificial leather; and drying, cooling and shaping to obtain a finished product of artificial leather. According to the water-scrubbing resistant artificial leather, the polyurethane surface layer and the surface treating agent which is composed of the polyurethane resin, the organic solvent, the neutralizing agent and the leveling agent are adopted so that the adhesion between the coating and the surface of the artificial leather is greatly improved, and the coating is unlikely to crack and fall off, resistant to water scrubbing, smooth in surface and good in wearing resistance.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a water-resistant and scratch-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: [0003] Step 1, select base cloth and release paper, prepare polyvinyl chloride surface layer slurry, polyvinyl chloride foam slurry, polyurethane laminating material and surface treatment agent, and described surface treatment agent is processed by the acrylic acid of 100...
