Decorative material for floor and its production method

Abstract

The present invention provides a decorative material for a floor having a feeling of uniform smoothness, flaw resistance and water resistance(moisture absorption resistance) and moreover having excellent design, and a method for manufacturing the same. In particular, the invention provides a decorative material using a wooden plate as a base material, which is characterized in that (1) the wooden plate has at least one of a tongue and a small hole formed by tongue and groove working, at a side face, (2) a synthetic resin layer with a thickness of 100 mum or more is laminated on the upper face of the wooden plate, and (3) a decorative sheet is laminated on the faces shown in (i)-(iii); (i) the upper face of the synthetic resin layer, (ii) the side face of the wooden plate, at least the face from the upper face end to the tongue region, and (iii) the side face of the woodenplate, at least the face from the upper face end to a small hole region.

Description

technical field [0001] The present invention relates to a floor decoration material and a manufacturing method thereof. Background technique [0002] Conventionally, as a decorative material for floors, a decorative material in which a decorative film is affixed to a base material composed of a wooden board is known. For example, Japanese Unexamined Patent Application Publication No. 2000-190309 discloses a wood decorative board for flooring, that is, a decorative film with a thin surface layer of natural wood is pasted on a base material composed of a wood plate, and a decorative film with a thin surface layer is pasted on the other side. A wood-based decorative board with a back sticking film, wherein the back sticking film is composed of a layer of a wood resin liquid that is difficult to seep through the wooden board. [0003] However, conventional floor coverings have insufficient damage resistance (impact resistance, tilt resistance), and are liable to generate simple...

AI Technical Summary

Problems solved by technology

[0003] However, the damage resistance (impact resistance, inclination resistance) of the existing decorative materials for floors is not sufficient, and simple recesses are likely to occur due to local loads, impairing uniform smoothness

[0004] In addition, during the floor construction process, it is necessary to connect the concave-convex of the multiple floor decoration materials that have been processed by tongue-and-groove processing (concave-convex on the side surface), and at this time, water may enter the joints, causing deformation or corrosion of the wooden boards.
