Skin layer for artificial leather and method for manufacturing artificial leather

Abstract

The present disclosure relates to a skin layer for artificial leather and a method manufacturing the artificial leather, and more particularly, to a composition of an inorganic pigment included in a skin layer. The skin layer for artificial leather, which is the present disclosure, may include a PVC resin, a plasticizer at 84 to 90 phr, and an inorganic pigment at 0.3 phr or more, and a method for manufacturing artificial leather includes: kneading a composition for forming a skin layer, and then forming a skin layer; laminating fiber fabric and the skin layer at a temperature of 150 to 180° C.; and subjecting the laminated fiber fabric and skin layer to roll compression, in which the composition for forming the skin layer may include a PVC resin, a plasticizer at 84 to 90 phr, and an inorganic pigment at 0.3 phr or more.

What is claimed is: 
     
         1 . A skin layer for artificial leather, comprising:
 a PVC resin;   a plasticizer at 84 to 90 phr; and   an inorganic pigment at 0.3 phr or more.   
     
     
         2 . The skin layer of  claim 1 , wherein the skin layer for artificial leather comprises an inorganic pigment at 0.3 phr to 0.7 phr. 
     
     
         3 . The skin layer of  claim 2 , wherein the skin layer for artificial leather has an average thickness of 370 μm or less. 
     
     
         4 . The skin layer of  claim 1 , wherein the skin layer for artificial leather has an average thickness of 370 μm or less. 
     
     
         5 . The skin layer of  claim 1 , wherein the plasticizer is one or more selected from diisodecyl phthalate, dipropyl-heptyl phthalate, trioctyl trimellitate, diisononyl phthalate, or diisononyl adipate. 
     
     
         6 . The skin layer of  claim 1 , further comprising:
 a heat stabilizer at 2 to 8 phr.   
     
     
         7 . The skin layer of  claim 1 , further comprising:
 a UV absorber at 0.2 to 0.6 phr.   
     
     
         8 . A method for manufacturing artificial leather, the method comprising:
 kneading a composition for forming a skin layer, and then forming a skin layer;   laminating fiber fabric and the skin layer at a temperature of 150 to 180° C.; and   subjecting the laminated fiber fabric and skin layer to roll compression,   wherein the composition for forming the skin layer comprises a PVC resin, a plasticizer at 84 to 90 phr, and an inorganic pigment at 0.3 phr or more.   
     
     
         9 . The method of  claim 8 , wherein a content of the inorganic pigment is 0.3 phr or more and less than 0.7 phr. 
     
     
         10 . The method of  claim 8 , wherein the laminated and compressed skin layer has an average thickness of 370 μm or less. 
     
     
         11 . The method of  claim 8 , wherein the composition for forming the skin layer comprises a heat stabilizer at 2 to 8 phr, or a UV absorber at 0.2 to 0.6 phr. 
     
     
         12 . The method of  claim 8 , wherein a kneading temperature of the composition for forming the skin layer is 120 to 160° C. 
     
     
         13 . The method of  claim 8 , wherein a roll compression temperature is 70 to 230° C.
