Abstract

PROBLEM TO BE SOLVED: To obtain a water-resistant panel adapted to a POP display panel usable outdoors even if it rains, excellent in waterproof properties, not lowering water-resistant capacity over a long period of time, enhanced in water-resistant capacity and having the large adhesive strength of a core material and water- resistant paper to generate no peeling. SOLUTION: The water-resistant panel is constituted by applying film surface processing 4 to the single surface of water-resistant paper 3, and turning the surface processed side of the water-resistant paper 3 outside to bond and laminate the water-resistant paper 3 to a styrene board 1 by a bond 2. The water absorption from the cross section of the surface material of a panel bonded part is not generated using the water-resistant paper, the adhesive strength with the core material is excellent and the water-resistant capacity of the water- resistant paper is enhanced by the bond, and the water-resistant panel not generating peeling or the lowering of the water-resistant capacity over a long period of time can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water resistant panel that can be used outdoors.

[0002]

2. Description of the Related Art A water-resistant display panel of this type is known in which printed YUPO (synthetic paper) is attached to a veneer or a styrene board. Further, there is used a printing paper in which a film of polypropylene or the like is surface-treated on at least one side of the printing paper and attached to a styrene board, cardboard or veneer.

[0003]

However, when the above-mentioned YUPO (synthetic paper) is pasted using a water-soluble bond (ethylene vinyl acetate emulsion, etc.), it will not adhere unless moisture is absorbed, so styrene board It cannot be bonded to a material that does not absorb water, such as (polystyrene foam resin), and it will be bonded to veneer, etc., but its adhesive strength is low and it can easily peel off. In addition, as a matter of fact, the surface-treated printed paper has a problem that if the surface of the cross section of the surface material absorbs water even if a little water such as rain is applied, the surface material is deformed or peeled due to a decrease in strength. there were.

In view of the above points, an object of the present invention is to provide a water resistant panel which does not deteriorate in performance even when exposed to rain outdoors.

[0005]

According to the present invention, a water-resistant paper having a film such as polypropylene on at least one surface thereof is surface-treated, and a water-soluble bond (ethylene vinyl acetate emulsion or the like) is used as an adhesive to form a core of styrene board or the like. A water-resistant panel, which is laminated with a surface treatment (coating with a film such as polypropylene) surface exposed to the outer surface after being laminated with a material.

The surface processing referred to in the present invention means vinyl coating, press coating, varnishing, P.P. P processing etc. In particular, P. If you attach a film by P processing etc., the water resistance is even better,
preferable.

The core material referred to in the present invention is styrene board,
Polystyrene resin such as styrene paper. Ethylene resin. Urethane resin. Natural rubber. veneer. Cardboard. Etc. In particular, a styrene board that does not allow water to permeate is more preferable and preferable.

The term "YUPO" as used in the present invention refers to synthetic paper. Especially, when surface treatment is not required, it is not performed.

In the water resistant panel of the present invention, ethylene vinyl acetate bond is applied to a styrene board as a core material, water resistant paper having a film of polypropylene or the like surface-treated on one side is installed beforehand, and pressure is applied to remove air. The waterproof paper takes in water and cures the bond. Once the bond hardens, it will not liquefy again. Tacking (adhesion processing) may be performed without using an adhesive as long as the required performance is not impaired.

A water resistant panel having the structure of the present invention will be described below with reference to the drawings. Fig. 1 Styrene board layer 1 is coated with ethylene vinyl acetate-based bond layer 2, and a water-resistant panel 3 of the present invention, which is laminated with water-resistant paper 3 having a film 4 on one side, is cured, then cut, cut, and punched And so on. FIG. 1 is a sectional view showing a state in which the water resistant panel of the present invention is integrated. For the core material, a suitable material is selected from soft and hard.

A third aspect of the present invention uses YUPO (synthetic paper) 6. The ethylene vinyl acetate based bond layer 2 is applied to the styrene board layer 1 and bonded to the waterproof paper 3, and then the waterproof paper and YUPO 6 are bonded using the adhesive 5. After the water resistant panel is cured, cutting, cutting, punching and other steps are performed. FIG. 2 is a sectional view showing a state in which the water resistant panel of the present invention is integrated.

According to a fourth aspect of the present invention, water resistant paper is laminated on the core material. Figure 3 shows the styrene board layer 1.
After the ethylene vinyl acetate-based bond layer 2 is applied and the water resistant panel of the present invention bonded to the water resistant paper 3 is cured, steps such as cutting, cutting and punching are performed. FIG. 3 is a sectional view showing a state in which the water resistant panel of the present invention is integrated.

As described above, the water-resistant panel of the present invention can be used outdoors because it has good adhesion to the core material and does not cause breakage of the face material in the cross section.

[0014]

[Comparative Example] Panel A is a water resistant paper (special rave weight manufactured by Tokushu Paper Co., Ltd .; 128 g / m ² ) with a polypropylene film P.O. P surface treatment, bonding with a core material of 5 mm styrene board, and curing and curing for 10 minutes. Panel B is a coated paper (weight; 128 g / m ² ) with a polypropylene film P.O. P surface treatment, bonding with a core material of 5 mm styrene board, and curing and curing for 10 minutes. Panel C is bonded to a waterproof paper with a core material of 5 mm styrene board and cured and cured for 10 minutes. Each of the obtained core materials was cut into 100 cm in length and width, immersed in water for a sufficient period of time, and water infiltration from the cross section was measured.

Panel A is submerged by 0.5 to 1 mm from the cut surface, Panel B is submerged by 12 to 15 mm from the cut surface, and Panel C is a water-resistant paper surface swelled and wrinkled to form a paper layer entirely. Damage.

The process of soaking in water for 10 minutes and drying at room temperature for 1 hour was repeated 5 times. Panel A is submerged by 0.5-1 mm from the cut surface, and Panel B is 30-4 from the cut surface.
0 mm of water immersion and peeling of the surface film occurred.

[0017]

EFFECTS OF THE INVENTION The water resistant panel of the present invention, having the above-mentioned constitution, has an excellent waterproofing property without breaking of the face material due to the permeation of water, and therefore has a water resistant property for a long period of time. Can be maintained. Also, the adhesion to the core material is good.

Further, since the adhesive bond penetrates the waterproof paper to form a film, and when cured, has a high waterproof property. Therefore, the bond forms a waterproof film on the surface of the waterproof paper to improve the water resistance of the waterproof paper.

Furthermore, the present invention can be used in combination with other core materials to change the panel strength and weight.
