Problems solved by technology

[0003] This general method has the following defects: First, because the patterned roller is used to print on the surface of the artificial leather, the pattern floats on the artificial leather, which affects the texture of the PU / PVC dry-process artificial leather leather, resulting in an unnatural look and feel of the leather; second, the printed pattern After use, the pattern is easy to fall off due to friction; the third is that the production process increases, and the produced PU / PVC dry-laid artificial leather products are printed again, which affects the product rate of the produced products

Embodiment 1

[0027] A kind of printing pattern PU / PVC dry-process artificial leather manufacturing method, 1, buy the release paper of market best-selling grain, select solvent-based polyurethane fabric resin, polyurethane bonding material, polyurethane printing material, polyvinyl chloride foam paste resin for use, and Suitable base cloth. The viscosity of the polyurethane fabric resin is 100000-200000cps, the content of non-volatile matter is 25%-35%, the viscosity of polyurethane printing resin is 500-3000cps, the content of non-volatile matter is 20%-50%, the polyurethane adhesive resin The viscosity is 60000-120000cps, and the content of non-volatile matter is 35%-50%. Polyvinyl chloride resin is an emulsion polymer resin with a K value of 65-75.

[0028] 2. Polyurethane coloring coating. The polyurethane PU is diluted to a dilution material with a viscosity value of 1300-1500 cps by using the dilution solvent dimethylformamide DMF, toluene TOL and butanone MEK, and the weight ratio...

Embodiment 2

[0034] The remaining steps of the printed pattern PU / PVC dry-process artificial leather manufacturing method of this embodiment are the same as in Example 1, which is to add a kneading process after the release: the obtained semi-finished product is placed in a kneading machine with a temperature of 50 ° C, kneaded After 40 hours of tattooing, the kneading process is completed.

[0035] The parts not described in this embodiment are the same as those in Embodiment 1.

Embodiment 3

[0037] This embodiment is basically the same as Example 2, except that the obtained semi-finished product is placed in a kneading machine with a temperature of 70° C., kneaded for 30 hours, and the kneading procedure is completed.

Abstract

The invention discloses a method for preparing PU / PVC artificial leather with a printed pattern by a dry method and PU / PVC artificial leather. The method comprises the following steps that: the following printing step is introduced to the main machine production equipment in the previous step, the structure of the artificial leather is changed, and the structure of the artificial leather orderly comprises a PU fabric layer, a printed pattern layer, a PVC foaming layer, a PU bonding layer and a base fabric layer. The method and the product have the advantages that: the printed pattern is arranged on the section of the artificial leather, and indistinctly emerges on the surface of the artificial leather, so that the artificial leather is beautiful and graceful and has natural impression and unique printing effect; and when the artificial leather is used, the pattern is not dropped due to friction, so that the beauty of the artificial leather is not affected.

Description

technical field [0001] The invention relates to a method for manufacturing artificial leather, in particular to a method for manufacturing PU / PVC artificial leather by a dry printing pattern method and the PU / PVC artificial leather. Background technique [0002] In the artificial leather manufacturing industry, the basic steps of the commonly used PU / PVC dry process artificial leather manufacturing with printed patterns are as follows: first, prepare the materials: provide release paper with three-dimensional leather texture, base cloth, polyurethane fabric, polyvinyl chloride foam paste Resin and polyurethane binder resin, etc.; followed by the main machine production: that is, coating the selected and prepared color polyurethane resin on the surface of the release paper, and coating the polyvinyl chloride foaming paste resin on the surface of the polyurethane after drying , and then apply the polyurethane adhesive to the foamed polyvinyl chloride foam paste resin, and atta...
