Problems solved by technology

[0003] When the concrete slab is directly attached to the floor finish material, there is a problem that if the curing reaction of the concrete slab is not completely completed, moisture will be absorbed from the back of the floor finish material after construction and the wooden slab will swell and warp.
[0005] However, the moisture-proof property of the flooring material described in Patent Document 1 is still insufficient, and especially when a decorative sheet is laminated on the front surface of the flooring material, it is not possible to sufficiently prevent the disadvantages (swelling, warping, etc.) caused by the moisture absorption of the wooden board.

Embodiment 1

[0097] (1) Use the adhesive (BA-10L / BA-11B, 9g / sq. ).

[0098] (2) Cut and process the above-mentioned sheet material into 3 pieces of width 313mm×length 1840mm by gang saw.

[0099] (3) Use the back groove processing machine to process the above-mentioned sheets with rear horizontal grooves, rear longitudinal grooves and strips (width 155mm×length 918mm.)

[0100] (4) Tenon processing and end chamfering processing (width 145 mm×length 900 mm) were performed on the above-mentioned sheet material using a tenon processing machine.

[0101] (5) A groove coating (groove coating: W-SF produced by Showa Ink Manufacturing Co., Ltd.) was applied to the square chamfered portion of the above-mentioned sheet using a groove coating line.

[0102] (6) A cushioning material made of non-woven fabric is bonded to the back surface with an adhesive, and a moisture-proof film is laminated. In this way, a decorative material for floors was produced.

[0103] The moisture-proof film was produc...

Embodiment 2

[0106] In said (6), except having used the laminated body of foamed polyurethane and foamed polyethylene as a cushioning material, it carried out similarly to Example 1, and produced the decorative material for floors. Specifically, as a cushioning material, a laminate (a total thickness of 5 mm) of polyurethane foam manufactured by Achilles and polyethylene foam manufactured by Toray was used.

Embodiment 3

[0108]In said (6), except having made the top coat layer of a moisture-proof film into polyurethane-type resin, it carried out similarly to Example 1, and produced the decorative material for floors. The moisture permeability of the moisture-proof film is 3g / m 2 ·24 hours.

Abstract

Provided is floor decoration material such that even in the case of material formed by laminating a decoration sheet on the front surface of a woody plate, the occurrence of swelling or warping due to moisture absorption is sufficiently restricted. This floor decoration material is formed in such a way that a decoration sheet is laminated on the front surface of a woody plate, and that a moisture-proof film is laminated on the back surface of the woody plate with cushion material therebetween. The floor decoration material is characterized in that the moisture permeability of the moisture-proof film at a temperature of 40OC and a humidity of 90% is 7 g / m2?24 hr or less.

Description

technical field [0001] The present invention relates to a decorative material for floors suitable for direct lamination on concrete slabs. Background technique [0002] Conventionally, floor finishing materials using wooden boards have been known. Especially in the case of floor finishing materials that are directly attached to concrete slabs in apartments, etc., cutting grooves may be provided on the back of the wooden slab in consideration of sound insulation and conformability to the concrete slab. In addition, in order to improve the walking feeling, etc., a cushioning material may be provided on the back of the floor decoration material. [0003] When the concrete slab is directly attached to the floor finish material, there is a problem that if the curing reaction of the concrete slab is not completely completed, moisture will be absorbed from the back of the floor finish material after construction, causing the wooden slab to swell and warp. When a decorative sheet ...
