Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for efficiently bonding a panel surface material used as a partition panel or a door panel for a toilet or a simple moving wall.

[0002]

2. Description of the Related Art FIG. 4 shows a cross section of a partition panel or a door panel which is frequently used for toilets. Fill a rectangular wooden frame (a) with a paper core (b),
Surface materials (c) and (c) are attached to both surfaces.
As the surface material (c), a decorative panel made of resin, a painted steel sheet, a ceramic panel, or the like is used to give an elegant appearance to the panel.

[0003] Incidentally, the above-mentioned frame body is a frame made of woody timber. Conventionally, a square bar obtained by cutting a laminated plate obtained by laminating thin plates into a bar shape is used, or a square bar obtained by cutting a medium fiberboard is used. Rods are used. By manufacturing a square bar using such a laminated board or a medium fiber board as a material, the strength is higher than that of a square bar made of general pure wood, and the frame body is also durable.

[0004] A paper core is filled in this frame to form a surface material.
(C) and (c) are pasted together.
In many cases, plywood is coated with a melamine resin or a polyester resin, or these resin sheets are bonded together. Also, since the surface of the plywood is uneven and does not form a smooth surface, even if the polyester resin is coated or a polyester resin sheet is adhered, the plywood pattern appears on the surface, and the quality of the surface is reduced. In some cases, a medium fiberboard obtained by processing and extracting wood fiber and pressing it together with an adhesive in a heated state is used.

[0005] When the above-mentioned medium fiber board is used as a surface material, a vinyl acetate resin-based adhesive is used as an adhesive for the medium fiber board. However, the surface materials must be overlapped and pressed for about 90 seconds, so that the bonding process takes a lot of time, which is a bottleneck in a panel manufacturing line and increases the cost of the panel.

[0006]

As described above, the method of bonding a partition panel or a door panel of a toilet or the like, and a panel surface material used as a simple moving wall has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a bonding method capable of bonding a surface material in a shorter time.

[0007]

The method for bonding panel surface materials according to the present invention is directed to a wooden panel, in which a paper core is filled in a frame framed by a wooden square member, and a wooden core is provided on both sides thereof. Panel attached with the surface material of FIG. Here, the woody material includes not only pure wood but also woody materials processed from wood, for example, veneer, laminated material, medium fiber material and the like.

A surface material is adhered to the frame filled with the paper core. A primer is applied to the surface material side, and an adhesive is applied to the frame and the core material side of the paper core. . That is, this is a method in which a surface material is bonded in a short time by using a primer which is a base adjustment agent and reacts with an adhesive to make it stick easily and the above-mentioned adhesive.

[0009] However, not only is the primer applied to the surface material and the core is coated with an adhesive but is superposed and pressed, but the core is heated to a predetermined temperature. When the temperature reaches a predetermined temperature by heating, the adhesive is applied, and the surface materials are overlapped and pressed. This pressing time is much shorter than in the case of pressing without heating, and is firmly adhered. Here, the heating temperature and the pressing time vary depending on the panel material and the types of the primer and the adhesive. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The panel surface material bonding method of the present invention comprises three steps. The first step is the surface material 1 shown in FIG.
Is a step of applying the primer 3 to the back surface 2 (adhesive surface) of the substrate, and the primer is applied using a spray, a roll coater, a brush, or the like. Here, the surface material is made of wood, and for example, a medium fiber board can be used, and the medium fiber board is manufactured by processing and extracting wood fiber and pressing it together with an adhesive in a heated state.

Therefore, the surface is smooth and fine without surface irregularities, and when the polyester resin layer is formed on this surface, the finished surface becomes good. Here, the primer is a surface conditioner as a surface material, and can react with an adhesive applied to the core material portion to improve the adhesive strength. About 6% of oxidized compounds and about 94% of water
It has become.

The second step is a step of heating the core member 4, wherein the core member 4 sandwiched between the both surface members 1 is heated to about 140 ° C.
Heat to about 150 ° C. As shown in FIG. 2, the core member 4 is formed by filling a paper core 7 into a frame formed by connecting vertical members 5, 5 and horizontal members 6, 6. Here, the vertical angle member 5 and the horizontal angle member 6 are made of wood, and for example, a medium fiber material can be used like the above-mentioned surface material.

Further, in order to increase the strength of the frame and prevent warping and deformation, the vertical angle member 5 and the horizontal angle member 6 have a laminated structure, and a thin plate is laminated inside with the medium fiber material as the outside. It can be a square member having a laminated structure sandwiching the material. As a heating means for the core portion 4, a hot press is generally used, but is not particularly limited.

FIG. 3 shows a case where both surface materials 1 and 1 are superimposed on a core material portion 4.
After being heated to about 150 ° C., the adhesive 8 is applied to the surface, and the surface material 1 is overlapped. About 1 after overlapping
Press and bond for 5 to 20 seconds. Of course, this is the case where one surface material 1 is bonded, and the same process is repeated to bond both surfaces.

The adhesive 8 is composed of about 26% of a modified acrylic resin, about 60% of water, about 11% of a filler, and about 1% of other preservatives and the like. Of course, the components of the primer and the adhesive are those in the case where the medium fiber material is used as the surface material and the frame, and when the wood material made of other material is used, the primer and the adhesive of different components are used. . Even if the same material, the same primer and the same adhesive are used, the time saving is about 50% as compared with a case where the core material is pressed without heating. As described above, in the method for bonding panel surface materials of the present invention, the frame and the surface material are made of wood, and the surface material is coated with a primer, and the frame is filled with a paper core. After the part is heated, the adhesive is applied and pressed, and the following effects can be obtained.

[0016]

According to the present invention, a primer is applied to a surface material, an adhesive is applied while a core material is heated to reach a predetermined temperature, and pressing is performed. Be shortened. That is, the time is reduced by about 50% as compared with a case where the same material and the same primer and adhesive are used. Obtaining an adhesive effect by heating a wood panel is far from the conventional adhesive technology. In the panel manufacturing, the bonding process of the surface material does not become a bottleneck, and the manufacturing cost of the panel is reduced.
