However, white electric oil is only limited to wiping some slight pollution such as sweat stains, watermarks, and mildew spots, and some more stubborn dirt, such as color pens that have not been cleaned up in time and have spread, coffee, cola, chemicals and industrial dyes. Stains, such stains must be removed with solvent-based cleaners. Usually, solvent-based cleaners are very corrosive, and the back and forth friction during cleaning and wiping will also cause further damage to the artificial leather, which makes ordinary leather products unusable. detergent for cleaning

[0022] The preparation method of the above-mentioned corrosion-resistant and wear-resistant artificial leather comprises the following steps:

[0023] Step 1. Coat the solvent-resistant slurry on the PU release paper, and dry at 110-130°C for 3 minutes to obtain the surface layer;

[0024] Step 2, apply the water-based polyurethane slurry on the surface layer, and dry at 110-130°C for 3 minutes to obtain the colored layer;

[0025] Step 3. Coat the polyurethane slurry on the colored layer with a coating thickness of 0.25-0.4mm, then dry and plasticize at 185°C for 2-3 minutes to obtain the PVC bottom layer;

[0026] Step 4. Coat the polyurethane laminating slurry or water-based laminating slurry on the PVC bottom layer to obtain the laminating layer, then laminate the base cloth with the laminating layer, and then dry it at 125-150°C. After cooling, the release paper is peeled off to obtain a corrosion-resistant and wear-resistant artificial leather.

[0027] It can be seen ...

Abstract

The invention discloses corrosion-resistant and wear-resistant artificial leather and a preparation method thereof, and belongs to the technical field of artificial leather. The corrosion-resistant and wear-resistant artificial leather comprises a surface layer, a coloring layer, a PVC bottom layer, a laminating layer and base cloth which are sequentially laminated; the surface layer is prepared by smearing solvent-resistant slurry; the solvent-resistant slurry comprises the following components in parts by weight: 100 parts of solvent-resistant resin PLT-3930, 0.5 part of a polyether siloxanecopolymer, 0.5 part of simethicone, 0.5 part of polyether modified polysiloxane and 0.8 part of an isocyanate curing agent. The surface layer of the corrosion-resistant and wear-resistant artificialleather has strong solvent resistance and scratch resistance, the surface is not damaged after 100 times of acetone solvent tests, the artificial leather does not fade after 1000 times of alcohol tests, the expansion of the artificial leather in the application range of solvent resistance and wear resistance color fastness is changed, the preparation method is simple to operate, different layers of the prepared artificial leather are tightly attached, and the surface layer is compact.

Description

technical field [0001] The invention belongs to the technical field of artificial leather, and in particular relates to a corrosion-resistant and wear-resistant artificial leather and a preparation method thereof. Background technique [0002] Artificial leather products will inevitably cause pollution during actual use, and some stains will appear. Usually, it can be wiped clean with white electric oil. However, white electric oil is only limited to wiping some slight pollution such as sweat stains, watermarks, and mildew spots, and some more stubborn dirt, such as color pens that have not been cleaned up in time and have spread, coffee, cola, chemicals and industrial dyes.
