Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a panel using a colored synthetic resin foam plate as a substrate, and more particularly to a panel containing a recycled synthetic resin foam plate that contains a recycled resin and is gray or black.
[0002]
[Prior art]
In recent years, recycling of trays and containers made of synthetic resin foams such as polystyrene foam has been promoted in order to reduce waste and effectively use resources.
When recycling trays and containers made of such synthetic resin foams, there are many colored colored trays and containers, and these colored trays and containers are used as white trays and containers. Sorting is difficult from the viewpoint of labor and cost, and the fact is that it is hardly implemented.
Therefore, the recycled resin including a colored tray and container is colored, and a foamed product using the colored recycled resin as a raw material is naturally a colored product.
[0003]
On the other hand, a panel in which a synthetic resin foam plate is used as a substrate and an adhesive layer is provided on at least one side of the substrate is widely used as an exhibition or decoration panel for a display panel or the like.
These panels have the color of the virgin raw material, that is, white, and a poster or the like showing a vivid color is pasted on the panel using the adhesive layer, or paper uses the adhesive layer. It is used as a display of various colors and shapes by coloring it using a poster color or the like on the paper surface and cutting it out like paperboard.
[0004]
Here, when the said panel is manufactured using the said recycled resin as a raw material, the obtained panel turns into a panel which uses the synthetic resin foamed board colored for the said reason as a board | substrate.
If a poster or the like is pasted on a panel having such a colored synthetic resin foam plate as a substrate, the color of the substrate appears through the poster, and the color of the poster may be different. In addition, even when paper is pasted, the color of the substrate appears on the paper through the paper, and the coloring by the poster color or the like may be different from the image.
Such a thing becomes a fatal fault as display or decoration panels, such as a display panel.
[0005]
Therefore, the present invention is not limited to the coloring of a poster or the like showing a vivid color, or the coloring of a poster color on a pasted paper surface, even in a panel using a colored synthetic resin foam board as a substrate. An object of the present invention is to provide a panel having a colored synthetic resin foam plate as a substrate, which can be performed without any problem, at low cost and easily.
[0006]
[Means for Solving the Problems]
As a result of diligent research to achieve the above-mentioned object, the present inventors pay attention to the adhesive layer formed for sticking a poster or the like, and conceal the coloring of the substrate by the adhesive layer. The present invention was completed.
That is, the present invention is a colored synthetic resin foam plate and has a gray or black and the substrate, the entire surface of at least one side plate surface of the substrate, the adhesive layer which is colored white is formed, on the adhesive layer A release sheet was attached to the panel, and the colored synthetic resin foam plate as the substrate was concealed by the white colored adhesive layer.
Further, the present invention uses a colored synthetic resin foam plate exhibiting gray or black as a substrate, and an adhesive layer colored white is formed on the entire surface of at least one side of the substrate. A paper sheet (but not peeled off like a release sheet) is adhered, and the colored synthetic resin foam plate as the substrate is concealed by the white colored adhesive layer. .
[0007]
According to the panel using the colored synthetic resin foam plate according to the present invention as a substrate, the color of the substrate is concealed by an adhesive layer colored in white, so the plate surface of the panel exhibits white. It is possible to attach brightly colored posters, etc., or to color the posters on the attached paper without any problem, and it will be a panel that can be used well as an exhibition or decoration panel such as a display panel. .
Moreover, according to the panel which used the above-mentioned colored synthetic resin foam board concerning this invention as the board | substrate, since the concealment of the coloring of this board | substrate is comprised by the adhesive bond layer currently formed in the board surface of a board | substrate conventionally Unlike the case where a new concealing layer is provided separately, the number of manufacturing steps is not increased, and the panel can be provided inexpensively and easily.
[0008]
Here, in the present invention, the colored synthetic resin foam plate, can be assumed to contain a recycled resin.
In general, since the color of the recycled resin is not constant, a product obtained using the recycled resin as a raw material cannot give a certain color. Here, since it is not preferable that the product has a different color, a pigment or dye such as carbon black or iron tetroxide is added to the recycled resin, and the resulting synthetic resin foam plate is colored gray or black, Is preferably a uniform product.
[0009]
Moreover, in the said invention, the said adhesive layer colored in the said white is a mixture layer of a white inorganic pigment and an adhesive agent, and shall be the formation thickness of 200-2000 micrometers .
[0010]
