Description

[0001]
[Industrial application fields]
The present invention relates to a recyclable decorative board and a decorative panel using the same.
[0002]
[Prior art]
Conventionally, a thermosetting resin decorative board such as a melamine decorative board or a polyester decorative board has a thermosetting resin-impregnated patterned paper on the surface of a thermosetting resin-impregnated core paper, and if necessary, a thermosetting resin-impregnated overlay paper. Were laminated and molded.
[0003]
And when manufacturing a decorative panel such as a steel desk top plate or a post-form processing counter using the thermosetting resin decorative plate as described above, the surface to be bonded and processed on the back surface of the thermosetting resin decorative plate is used. Sanded and roughened for use.
[0004]
In addition, a strong adhesive such as a rubber adhesive or urethane adhesive is used to bond a thermosetting resin decorative board with a sanding treatment as described above to a core material such as an iron plate or plywood. It was.
[0005]
And the decorative panel made by bonding the thermosetting resin decorative board to the core material can be used as it is for a long time, as a top plate for a steel desk, a deck for a sink or vanity, a counter for a store, etc. Was.
[0006]
[Problems to be solved by the invention]
Therefore, the above sanding process is troublesome and has the disadvantages that sanding waste is generated as waste.
[0007]
In addition, a strong adhesive required to withstand the difference in expansion and contraction between the thermosetting resin decorative board and the core material was required.
[0008]
And even if you try to replace the thermosetting resin decorative board due to model change of the decorative panel or scratches on the surface, it can not be peeled off and discarded in the state of a steel desk or counter or the top plate part There was a problem in terms of effective use of resources.
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to provide a thermosetting resin decorative board that does not require backside sanding and a decorative panel that can easily peel off the surface decorative board after the bonding process when bonding to a core material.
[0010]
[Means for Solving the Problems]
The present invention is a decorative board in which a non-impregnated paper made of paraffin-coated paper is laminated and integrated on the back surface of a thermosetting resin laminated board layer .
[0011]
A decorative panel is characterized in that the decorative plate according to claim 1 is laminated and integrated on the core material with an adhesive interposed therebetween, with the back surface facing the core material side .
[0012]
Hereinafter, the present invention will be described with reference to the drawings of the embodiments. FIG. 1 shows a structural cross-sectional view of the decorative panel of the present invention, and FIG. 2 shows a structural cross-sectional view of the decorative panel of the present invention.
[0013]
In order to produce the decorative board of the present invention, for example, as shown in the drawings, a melamine resin, diallyl phthalate resin, unsaturated polyester is applied to an overlay paper made of thin paper, or a patterned paper having a desired coloring or pattern. Thermosetting resin impregnated overlay paper 10 impregnated and dried with a thermosetting resin such as resin, phenolic resin impregnated core paper, diallyl phthalate resin impregnated core paper with laminated thermosetting resin impregnated pattern paper 11 on the surface, Resin for core impregnation such as coated paper or printing paper (titanium paper) hardly penetrates into the back surface of the thermosetting resin impregnated laminate 1 made of thermosetting resin impregnated core paper 12 such as saturated polyester resin impregnated core paper. Paper is suitable, but by laminating and integrating the desired number of ordinary unimpregnated paper 2 such as kraft paper and laminating and heating and molding,粧板 is obtained.
[0014]
Next, the decorative panel of the present invention is generally manufactured by attaching the decorative plate of the present invention to a core material 4 made of a base material such as a wood board such as plywood, MDF, and particle board, or a steel plate, with an adhesive 3. However, it can also be obtained by applying the adhesive 3 to the core material 4 at the time of manufacturing the decorative board and simultaneously molding it.
[0015]
Adhesive 3 is not particularly limited, and emulsions of thermoplastic resins such as vinyl acetate resins and acrylic resins, organic solvent dispersion types, condensation resins such as urea resins, melamine resins, phenol resins, chloroprene resins, There are latex of synthetic rubber such as styrene butadiene, organic solvent type, addition polymerization type resin such as urethane resin and epoxy resin, etc., which can be arbitrarily used from commercially available adhesives depending on the properties and required performance of the core material.
[0016]
【Example】
Example 1
Resin-impregnated core paper consisting of three core papers that are impregnated with kraft paper and dried on an unimpregnated paper made of paraffin-coated paper with a basis weight of 100 g / m ² , and a melamine resin initial condensate impregnated with an aqueous solution, the pattern paper to dry and by sequentially stacking the respective one over over lay paper, inserted into the molding press by sandwiching the plating plate, 0.99 ° C., after heating pressure forming for 30 minutes at 100 Kg / cm @ 2, and depressurized cooled with water to 40 ° C., unimpregnated paper consisting of paraffin-coated paper to the rear surface of the thermosetting resin laminate layer to obtain a decorative laminate that is laminated and integrated.
[0017]
Example 2
The makeup obtained in Example 1 was applied to a surface of about 130 g / m ^{2 of} Aika Ivon RC-ET (manufactured by Aika Industry Co., Ltd.), a solvent-type chloroprene-based adhesive, on a steel plate as a core material for a steel desk top plate. A face coated with about 130 g / m ² of the above adhesive was pasted on the unimpregnated paper surface of the board to obtain a decorative panel of the present invention.
[0018]
【The invention's effect】
In the decorative board of the present invention, since the non-impregnated paper layer is laminated and integrated on the back surface layer, it is not necessary to sand for bonding.
[0019]
Further, the decorative panel after the bonding process has an unimpregnated paper layer between the core material and the thermosetting resin-impregnated laminated board, so that it can be easily peeled off, and another decorative board is provided on the peeled-off decorative panel. It is also easy to bond them.
[0020]
Therefore, it is useful as a replaceable decorative plate, that is, a decorative plate for recycling, and is useful as a surface decorative material for furniture and fittings such as a top plate for a steel desk, a top plate for a sink and a sink.
