Flooring having pla layer

Abstract

Disclosed therein is a flooring, which can secure environment-friendliness by forming a surface layer laminated on an upper face of a base layer using PLA (Poly Lactic Acid) resin instead of wood, easily provide a handcraft surface texture by applying a curved pattern onto the surface of the surface layer using embossing rollers at the time that the surface layer is manufactured, and prevent compression, scratches, discoloration, and so on in comparison with woods. The flooring constructed on a floor of a building includes: a base layer made from one of an MDF, an HDF, and a plywood; and a surface layer having a reinforced layer, a printed layer, and a transparent layer which are laminated on an upper face of the base layer in order, at least one of the layers being made of PLA (Poly Lactic Acid) resin. A curved pattern is formed on an upper face of the surface layer.

1 . A flooring constructed on a floor of a building, the flooring comprising: a base layer made from one of an MDF, an HDF, and a plywood; and
 a surface layer having a reinforced layer, a printed layer, and a transparent layer which are laminated on an upper face of the base layer in order, at least one of the layers being made of PLA (Poly Lactic Acid) resin, wherein a curved pattern is formed on an upper face of the surface layer.   
     
     
         2 . The flooring according to  claim 1 , wherein the curved pattern is formed through a process of compressing the surface layer after passing the surface layer between a pair of rotating embossing rollers. 
     
     
         3 . The flooring according to  claim 2 , wherein at least one of the embossing rollers has a protrusion of a predetermined shape disposed on an outer circumferential surface thereof so as to form the curved pattern by compressing one side of the surface layer. 
     
     
         4 . The flooring according to  claim 1 , wherein the surface layer is laminated on an upper face of the base layer by a medium of a bonding layer of thermosetting melamine resin. 
     
     
         5 . The flooring according to  claim 4 , wherein the surface layer comprises a UV coated layer laminated on the upper surface thereof. 
     
     
         6 . The flooring according to  claim 1 , further comprising a balance layer disposed below the base layer for balancing against curling of upper and lower parts of the flooring. 
     
     
         7 . The flooring according  claim 2 , wherein the surface layer is laminated on an upper face of the base layer by a medium of a bonding layer of thermosetting melamine resin. 
     
     
         8 . The flooring according  claim 3 , wherein the surface layer is laminated on an upper face of the base layer by a medium of a bonding layer of thermosetting melamine resin. 
     
     
         9 . The flooring according to  claim 7 , wherein the surface layer comprises a UV coated layer laminated on the upper surface thereof. 
     
     
         10 . The flooring according to  claim 8 , wherein the surface layer comprises a UV coated layer laminated on the upper surface thereof. 
     
     
         11 . The flooring according to  claim 5 , further comprising a balance layer disposed below the base layer for balancing against curling of upper and lower parts of the flooring. 
     
     
         12 . The flooring according to  claim 9 , further comprising a balance layer disposed below the base layer for balancing against curling of upper and lower parts of the flooring. 
     
     
         13 . The flooring according to  claim 10 , further comprising a balance layer disposed below the base layer for balancing against curling of upper and lower parts of the flooring.
