Problems solved by technology

However, the use of papers containing titanium dioxide to maximize resin impregnation resulted in poor printability despite superior impregnation properties compared to low basis weight tissue papers
Also, acrylate type UV coatings cannot be used due to melamine impregnation
Also, impregnated melamine is cold to the touch and, by its nature, can generate static electricity

Embodiment 1

[0054] 1. Preparation of Substrate 10

[0055] The polyvinyl chloride resin layer having a thickness of 1.0˜5.0 mm is formed of a composition including a PVC resin, a plasticizer, a filler, a stabilizer, and the like.

[0056] Chipboard and high-density fiberboard are produced by pressing shavings or fibers obtained by cutting or fiberizing wood in a melamine resin, followed by shaping.

[0057] 5 to 7 veneers are laminated together using melamine resin in such a manner that the grain directions of the veneers are at right angles to each other, and the laminated board is extruded by a press, thereby preparing a waterproof plywood layer.

[0058] 2. Preparation of Printed Wood Veneer Layer 20

[0059] 1) Preparation of primer-treated UV coating 21

[0060] A 6-10 minute UV application is performed to impart surface protection and high quality appearance. The amino resin impregnated low basis weight paper layer 22 was treated with an acryl based primer followed by UV coating....

Abstract

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.

Description

technical field [0001] The present invention relates to a back-grooved laminated wooden floor for floor heating systems comprising layers selected from polyvinyl chloride resin, oriented strand board (OSB) and high-density fibreboard (HDF) and waterproof plywood A base layer of layers and a printed wood veneer layer laminated on top of the base layer. More specifically, the present invention relates to a UV surface-coated laminate wood floor for floor heating systems comprising a base layer with a back groove, an adhesive layer and a printed wood veneer layer, wherein the printed The wood veneer layer includes a veneer layer laminated sequentially from the bottom, a resin-impregnated low-weight paper layer, and a primer-treated UV coating, and the base layer with a back groove and the printed wood veneer layer are bonded to each other through an adhesive layer. bonding. Background technique [0002] Figure 1 is a cross-sectional view of a conventional wood floor for floor ...
