preparation example Construction

[0011] The present invention provides a method for preparing PU / PVC composite artificial leather. The post-treatment slurry is sprayed on the surface of the semi-finished PU / PVC composite artificial leather to obtain the PU / PVC composite artificial leather. The post-treatment slurry includes the following raw materials in parts by weight : 95-105 parts of spray treatment agent, 180-200 parts of methyl ethyl ketone, 150-180 parts of CYC and 3-5 parts of dye water.

[0012] As can be seen from the foregoing description, the beneficial effects of the present invention are:

[0013] Design the post-treatment slurry with the above ratio, and spray the post-treatment slurry on the surface of the semi-finished PU / PVC composite artificial leather as required, so that the leather surface can obtain a gradient color effect, which has the advantages of strong color layering and strong three-dimensional texture.

[0014] Further, the spraying is carried out at an angle of 20-60° to the su...

Abstract

The invention relates to a preparation method of PU / PVC (Polyurethane / Polyvinyl Chloride) composite artificial leather. The PU / PVC composite artificial leather is obtained by spraying post-treatment slurry on the surface of a semi-finished product of PU / PVC composite artificial leather, wherein the post-treatment slurry is prepared from the following raw materials in parts by weight: 95 to 105 parts of a spraying treatment agent, 180 to 200 parts of methyl ethyl ketone, 150 to 180 parts of CY and 3 to 5 parts of dyestuff water. By adopting the preparation method of the PU / PVC composite artificial leather, provided by the invention, the surface of the obtained PU / PVC composite artificial leather can obtain a gradient effect and the PU / PVC composite artificial leather has the advantages of strong color layering and strong line stereoscopic impression.

Description

technical field [0001] The invention relates to artificial leather technology, in particular to a preparation method of gradient color PU / PVC composite artificial leather. Background technique [0002] PU / PVC composite artificial leather is an artificial leather made of PU material as the surface layer, PVC foam material as the bottom layer, and then laminated with artificial leather base cloth. The PU / PVC composite artificial leather in the prior art has the disadvantages of monotonous leather surface color and no gradient effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of PU / PVC composite artificial leather with rich leather surface color and gradual color effect. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A preparation method of PU / PVC composite artificial leather, spraying post...
