摘要 (英语) Disclosed herein is a UV surface-coated laminate wood flooring for an under-floor heating system comprising a back-grooved base, an adhesive layer and a printed wood veneer layer wherein the printed wood veneer layer is produced by impregnating and coating a low-basis weight printed paper with a thermoplastic or thermosetting resin, integrally forming the paper layer with a low-price reinforcing layer by pressing under high pressure, treating the surface of the paper layer with an acryl based primer, and coating the primer-treated paper layer with a solvent-free type UV coating paint, and wherein the back-grooved base and the printed wood veneer layer are adhered to each other by the adhesive layer.
摘要 - DWPI A laminate wood flooring has a back-grooved base (10), an adhesive layer (40), and a printed wood veneer layer (20) laminated in this order from the bottom wherein the printed wood veneer layer includes a reinforcing layer (23), a resin-impregnated low-basis weight paper layer (22), and a primer-treated ultraviolet coating layer (21) laminated in this order from the bottom. Used for an under-floor heating system (claimed). The invention has improved adhesion and surface strength by impregnation of low-basis weight printed paper and integration technique of the printed paper and a reinforcing layer. Preferred Components: The laminate wood flooring further comprises a soundproof layer laminated in a position between the base and the printed wood veneer layer or below the base. Preferred Materials: The resin-impregnated low-basis weight paper layer is produced by printing a tissue paper having a basis weight of 25-50 g/m 2 and impregnating the printed tissue paper with a resin consisting of urea resin, urea-melamine resin, melamine resin, phenol resin, acryl resin, polyester resin, unsaturated polyester resin, epoxy resin, polyvinyl acetate resin, polyvinyl alcohol resin, or urethane resin. The reinforcing layer and the resin-impregnated low-basis weight paper layer are integrally formed by coating the resin, and pressing the coating in a high-pressure press. The primer-treated ultraviolet (UV) coating layer is produced by coating an acryl based primer on the resin-impregnated low-basis weight paper layer, followed by UV coating. The acryl based primer and the UV coating paint are solvent-free type. The reinforcing layer is s a veneer, a shielding paper, a high-density fiberboard (HDF), or a craft paper. The base is consisting of polyvinyl chloride resin layer, a high-density fiberboard (HDF), an oriented strand board (OSB), or a waterproof plywood layer. The figure is a cross-sectional view of UV surface-coated laminate wood flooring.10Base20Printed wood veneer layer21UV coating layer22Low-basis weight paper layer23Reinforcing layer40Adhesive layer
