Problems solved by technology

[0006] However, the building material described in Patent Document 1 has the problems of low impact resistance and insufficient scratch resistance of the resin cross-linked foam.
In addition, when installing mortise and tenon joints or chamfering on the side of the building material, if the resin cross-linked foam is cut, the resin cross-linked foam will be welded to the cutting blade, and there is a problem that cutting is difficult.
In addition, when the above-mentioned building materials are used as floor materials to construct the floor surface, the resin cross-linked foam will be formed between other adjacent floor materials at the mortise and tenon fitting part due to walking on the floor surface. Rubbing against each other, resulting in floor creaking (座声り); when the above-mentioned building materials are used as wall or ceiling panel materials, due to the air flow in the room, contact with objects or people, etc., the resin is cross-linked like floor materials Foams rub against each other at the mortise and tenon joints, and there is a problem that a sound similar to the creaking sound of the floor (squeak (打み音)) is produced.
[0007] In addition, for the decorative flooring material produced by the production method of Patent Document 2, the structure for fully exerting the performance as a flooring material such as heat insulation and suppression of floor creaking has not been sufficiently studied, and there is a problem that these performances are insufficient.

Embodiment 1

[0205] Using an ink composition (acrylic urethane system), a pattern layer of a stone pattern with a thickness of 2 μm was formed on a colored polypropylene resin film (thickness: 60 μm, color: white system) by gravure printing.

[0206] Next, an adhesive layer with a thickness of 2 μm was formed using a urethane-based adhesive for dry lamination, and a transparent polypropylene resin film (thickness: 80 μm) was provided on the pattern layer by dry lamination.

[0207] On this transparent polypropylene resin film, an undercoat layer with a thickness of 1 μm was formed using a two-component curable urethane resin. Then, on this primer layer, by gravure printing with coating amount 15g / m 2 Apply an electron beam-curable resin composition (acrylate-based) to form a coating film, irradiate electron beams to crosslink and cure the coating film, form a surface protection layer (thickness: 15 μm), and produce a decorative sheet (thickness: 160 μm), as a decorative layer.

[0208] N...

Embodiment 2

[0210] For Example 1, the non-foamed resin layer was changed from PP resin sheet to ABS resin sheet (thickness; 2mm), the mortise and tenon processing was changed from tongue-and-groove to butt joint, and the sticking of the foamed resin layer was changed from mortise and tenon After the processing, the decorative material was produced in the same manner as in Example 1 except that before the mortise and tenon processing was performed. The gap amount of the foamed resin layer when the produced decorative materials were fitted together was 2 mm.

Embodiment 3

[0212] Decorative materials were produced in the same manner as in Example 1 except that the gap between the foamed resin layers when fitting decorative materials was adjusted to 0.5 mm.

Abstract

Provided is a decorative material as a floor material that suppresses the generation of creaking noise, a panel material for walls or ceilings that suppresses the generation of creaking sound. A decorative material comprising a foamed resin layer and a non-foamed resin layer and having a polygonal shape in plan view, wherein the non-foamed resin layer has a tenon on at least one side of the polygon, The above-mentioned non-foaming resin layer on at least the other side has a mortise portion that can be embedded in the above-mentioned tenon portion, and the tenon portion of one of the above-mentioned decorative materials and the mortise portion of the other above-mentioned decorative material can be placed on the above-mentioned foamed resin layer of the above-mentioned one decorative material. The layer is embedded in a state where it is not in contact with the foamed resin layer of the above-mentioned other decorative materials.

Description

technical field [0001] The present invention relates to a decorative material and a method for manufacturing the decorative material. Background technique [0002] Traditionally, decorative materials for interiors have generally used wooden substrates such as plywood, individual wood fiber boards, and composite substrates, and surface decorative materials such as decorative sheets, decorative paper, and sliced ​​veneers are laminated. [0003] Since these decorative materials for interior decoration have low thermal insulation performance, there is a problem that they feel cold when touched by hands or feet in winter or other low temperature conditions. [0004] In addition, in summer or winter, when air conditioners such as air conditioners or heaters are used indoors, a lot of energy is required to cool or heat the indoor surfaces to the target temperature, and there is a problem of high electricity costs. [0005] In order to improve the above-mentioned problems, propose...
