Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decorative sheet.

[0002]

[Prior Art]

 Conventionally, a decorative sheet attached to a door material, a kitchen door, a general building material, furniture, etc. by covering the surface thereof to improve the decorative property is widely used.

[0003]

[Problems to be solved by the device]

 However, many of the conventional decorative sheets whose surface is coated with a thermosetting resin are often used, and they are inferior in scratching property (change of the barge caused by rubbing the surface) and are often scratched innumerably. Therefore, the appearance of a cosmetic sheet having excellent surface scratch resistance is strongly desired. In addition, for example, in the case of a wood grain decorative sheet, there was a problem that the surface siding did not look natural unlike the luster of natural wood.

In view of the above-mentioned drawbacks of the prior art, the present inventor coated a surface of a base material sheet with a three-dimensional cross-linking structure film, and thus was extremely excellent in scratch resistance and also excellent in solvent resistance. The inventors have found that a sheet can be obtained, and that the three-dimensional crosslinked structure coating contains a port modifier to prevent scratches and stains on the surface, and can also express natural luster like natural wood.

[0005]

[Means for Solving the Problems]

 That is, the present invention provides a decorative sheet comprising a base material sheet, a pattern layer provided on the sheet, and a three-dimensional crosslinked structure coating provided on the surface of the base material sheet. It is characterized by containing a port regulator.

The three-dimensional cross-linking structure coating 4 is formed by coating an electron beam curable resin or an ultraviolet curable resin on the surface of the base material sheet 2 so as to cover the pattern layer 3, and then irradiating with an electron beam or ultraviolet rays. Thus, the resin is crosslinked, and thus the resin is crosslinked and cured.

As the electron beam curable resin, epoxy acrylate, urethane acrylate, acrylic acid modified alkyd, acrylic modified polyester, etc. are used as oligomers, and neopentyl glycol is used for the purpose of adjusting the cross-linking structure and viscosity. -Mixed with monomers such as diacrylate, pentaerythritol triacrylate, trimethylol propane triacrylate, and trimethylol propane trimethacrylate.

Further, examples of the ultraviolet curable resin include those obtained by further adding a photoinitiator such as a benzoin-based, acetophenone-based, benzylketal-based, or ketone / amine-based resin to the electron beam-curable resin.

Furthermore, silica gel, calcium carbonate, inorganic substances such as precipitated barium, and organic substances such as polyethylene particles are added to the above electron beam and ultraviolet ray curable resins as a port regulator.

Further, polyethylene wax, fatty acid soap or the like may be added as an auxiliary agent for improving scratch resistance.

Examples of the coating method of the above resin include gravure coating, roll coating, reverse roll coating, flow coating, spray coating, and smoothing coating.

As a curing method, in the case of an ultraviolet curable resin, a high pressure mercury lamp, a metal halide lamp, a xenon lamp, a low pressure mercury lamp or the like is irradiated to cure the resin. Further, in the case of an electron beam curable resin, a curtain type or a scanning type can be used by using an accelerator using a tungsten filament.

The decorative sheet 1 can also be obtained by providing the decorative sheet 1.

Hereinafter, the present invention will be described in more detail with reference to specific examples. Example 1 A wood grain pattern was printed on a vinyl chloride coloring sheet (Riken Vinyl 0.1 m / m) as the first layer of the base sheet, and a clear vinyl chloride sheet (Riken Vinyl 0.1 m / m) was printed on it. Heat-laminating is performed to form the second layer. At this time, embossing is performed with a roll having a convex conduit pattern having a plate depth of 90 μ, thereby forming an uneven sheet in which a pattern is laminated in the middle of a PVC sheet. Then, the recess is colored by wiping a two-component curing type ink. On top of this, a roll-coating method was used to apply a UV-curable paint with a thickness of 20μ mainly composed of epoxy acrylate and a gloss modifier, and four ozone-type high-pressure mercury lamps with a power of 80 w / cm were turned on. However, by irradiating at a speed of 10 m / min, it was possible to obtain a decorative sheet with a high design, which was extremely excellent in the scratch resistance and solvent resistance of the surface and resembled a natural wooden bark.
