Problems solved by technology

[0007] However, if the laminated body for flooring materials is affected by the heat of the heating means, the following effects are often seen: the laminated body for flooring materials is warped due to thermal contraction or thermal expansion of the plywood or synthetic resin layer, and the laminated body for flooring materials is warped. When the pattern design is applied to the surface of the decorative layer of the laminated body, along the direction of the fibers of the surface layer of the plywood, concave and convex shapes, etc. are produced.

Abstract

The invention discloses a sheet for flooring materials, which is composed of a synthetic resin layer and a decorative layer formed thereon, wherein the synthetic resin layer is divided into two or more independent areas. . The present invention also discloses a laminate for flooring materials, which is composed of the above-mentioned sheets for flooring materials laminated on an essential base material.

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of March 31, 2004, an application number of 200410033233.8, and an invention title of "laminated body for floor materials". technical field [0002] The present invention relates to a laminate for flooring excellent in caster resistance, impact resistance and water resistance. Background technique [0003] Conventionally, as flooring materials, a wooden decorative veneer is laminated and coated on a plywood, or a plywood and a medium density fiberboard (MDF) are laminated, and a wooden decorative veneer is further laminated on the MDF and coated. floor material. Also known are flooring materials that are grooved and chamfered to the depth of plywood and MDF from the side of the wood veneer and provided with grooves and chamfers to improve the design of the pattern. [0004] However, wooden decorative veneers are obtained by thinly slicing natural wood witho...
