Embodiment

[0017] Embodiment: a kind of manufacture method of artificial leather, comprising:

[0018] (1) Input the rolls of special-shaped paper to the coating machine, that is, the paper mold;

[0019] (2) The ratio (weight ratio) of the slurry coated by No. 1 coater to the paper mold for the first time is 100 parts of polyvinyl chloride paste resin (PVC), 60 parts of dioctyl phthalate (DOP) 2 parts, 3 parts of additives or polyurethane PU, after stirring and filtering, enter the oven for plasticization and curing, and then transfer to No. 2 coating machine;

[0020] (3) The ratio (weight ratio) of the slurry coated by No. 2 coater for the second time is 100 parts of polyvinyl chloride paste resin (PVC), 70 parts of dioctyl phthalate (DOP), and auxiliary agent Add an appropriate amount of coloring material and 2 parts of foaming agent azodicarbonamide (ADCA), after stirring and filtering, enter the oven for plasticization and foaming. The foaming process is controlled at 1-2 minutes,...

Abstract

The invention relates to a method of manufacturing leatheroid, which includes steps: coil hetero-paper is imported to casting machines, first coat paste to the hetero-paper by No.1 casting machine is mixer of PVC, DOP and auxiliary agent after being stirred and filtered or polyurethane, and is transported to No.2 casingt machine after baking oven plasticizing and curing; second coating paste is mixer of PVC, DOP, auxiliary agent, pigment and foaming agent after being stirred and filtered, and is transported to No.3 coating machine after baking oven plasticizing and foaming; third coating paste is adhesive and coved with textile cloth, is separated from the hetero-paper after baking oven solidifying, cooling and fixing and is transmitted to quality detection and eligible finished product packaging; the leatheroid peeled hetero-paper is coiled to reuse after being checked. Surface layer of the invention is not added with pigment, so the surface layer is transparent, can show dull polish and water washing effect, has no shortcomings of fading, color deposition or transferring to neighboring article, and the transparent surface layer is wearable, scrape resisting and easy cleaning.

Description

technical field [0001] The invention relates to the field of artificial leather manufacturing, in particular to a method for manufacturing artificial leather. Background technique [0002] The surface layer of the existing artificial leather is colored, opaque, and cannot show the appearance of frosted or washed, and the color of the surface layer is easy to fade, precipitate or migrate to adjacent articles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing artificial leather with a transparent surface, which can show the appearance of sanding and washing. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] 1. A method for producing artificial leather, characterized in that it may further comprise the steps: [0006] (1) Input rolls of special-shaped paper to the first coating machine, that is, paper m...
