Problems solved by technology

However, places such as windows, washrooms and lavatories are environments with a lot of condensation or water (humidity, urine, etc.), and there is a large temperature difference between hot summer and cold winter, so if the decorative panels used in these places are wooden material, it is easy to mold or warp due to poor water resistance, and cannot be used stably

Embodiment 1

[0260] 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.

[0261] 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.

[0262] On this transparent polypropylene resin film, an undercoat layer having a thickness of 1 μm was formed using a two-component curing type 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.

Embodiment 2～6、 comparative example 1～4

[0268] A decorative material was produced in the same manner as in Example 1 except that the foamed resin layer and the non-foamed resin layer shown in Table 1 were replaced.

[0269] Table 1 shows the results of evaluation of the obtained decorative material.

[0270]

[0271]

[0272] In addition, in Table 1, the place described as "not evaluated" means that the sample did not maintain the shape in the adhesion evaluation of the upper layer, and therefore evaluation was not possible.

[0273] As shown in Table 1, the decorative materials of the examples all had a good adhesion state at the bent portion, and were also excellent in the adhesion evaluation of the bent portion.

[0274] On the other hand, since the decorative material of Comparative Example 1 used a solvent-based rubber adhesive as the first adhesive and the second adhesive, the foamed resin layer was dissolved. The decorative material of Comparative Example 2 uses alcohol-based rubber adhesives as the fi...

Abstract

The present invention provides a decorative material that is excellent in water resistance and heat insulation, and has excellent adhesiveness of a bent portion formed by bending. The present invention relates to a decorative material comprising a decorative layer, a non-foamed resin layer, and a foamed resin layer, characterized in that it has a surface formed by bending a surface opposite to the decorative layer. The bent portion has a first adhesive and a second adhesive on a surface of the bent portion that is in contact with the bent portion.

Description

technical field [0001] The present invention relates to decorative materials. Background technique [0002] Conventionally, wooden materials have been used as decorative materials for window edges (bay windowsills), toilets and washrooms (floor materials) and the like (for example, refer to Patent Document 1, etc.). However, places such as windows, washrooms and lavatories are environments with a lot of condensation or water (humidity, urine, etc.), and there is a large temperature difference between hot summer and cold winter, so if the decorative panels used in these places are wooden However, due to poor water resistance, it is easy to mold or warp, so it cannot be used stably. [0003] In order to satisfy the water resistance of such a decorative material, it is considered to utilize a resin material as a non-wood material to constitute a decorative material, and particularly a decorative material having a resin foam layer excellent in water resistance and heat insulati...
