  • Wood flooring composed of WPL, base and soundproof layer
    Patent number: 7473457
    Abstract: Disclosed herein is a back-grooved laminate wood flooring in which a wood veneer of high pressure resin impregnation laminate (WPL) is laminated on a base selected from a vinyl chloride (PVC) resin layer, on oriented strand board (OSB), a high-density fiberboard (HDF) and a waterproof plywood. More specifically, the back-grooved laminate wood flooring comprises a WPL (20), an adhesive layer (40) and a base (10) (a polyvinyl chloride resin layer, OSB, HDF or waterproof plywood) wherein the WPL (20) includes a base-reinforcing layer (24), a natural veneer layer (23), a resin-impregnated overlay layer (22) and a surface UV coating layer (21) layered in this order from the bottom.
