Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated panel suitable for use as, for example, an interior wall material, a ceiling material, a floor material and the like of a building, and a method of manufacturing the laminated panel.

[0002]

2. Description of the Related Art Hitherto, a laminated panel formed by laminating a plurality of face materials is known, and such a laminated panel is used, for example, as an inner wall material, a ceiling material, a floor material, and the like of a building. . There are various types of laminated panels, such as lamination of different materials, such as double lamination of different materials, in addition to lamination of the same material. For example, as an example of a laminated panel by double bonding of the same material, an inner wall material of a double-plastered gypsum board is mentioned, and this inner wall material is used for fire prevention of a wooden three-story building, a barrier wall of an apartment house, and the like. I have. Examples of a laminated panel formed by double bonding of different materials include a urethane foam-lined decorative gypsum board and a laminated panel of plywood and a cement board. Of these, the urethane foam-lined gypsum board has been used as a ceiling material or the like on the top floor because of its high heat insulation property, and has been increasingly used as a ceiling material or the like of each floor because of its high sound insulation. Furthermore, laminated panels of plywood and, for example, wood chip-containing cement boards have been used as floor panels for semi-refractory structures.

However, in such a conventional laminated panel, the behavior of dimensional change due to temperature and humidity of each material is different in the double bonding of different materials. In addition, even when the same type of material is double-bonded, the behavior of the dimensional change may be different depending on the environmental conditions of each face material. for that reason,
The laminated panel was warped or peeled off.

Therefore, various measures have been taken to prevent such a laminated panel from warping or peeling. First, as a first means, an elastic adhesive, such as a rubber butyl adhesive, which does not completely solidify even when bonded, is used. In this case, the elastic adhesive is spread with a spatula or the like after being applied with a caulking gun. Further, as the second means, the above-mentioned floor panels and the like are individually fixed. That is, the attachment of the quasi-fireproof floor panel is as follows. First, the plywood is fixed to the joist by nailing, then an adhesive is applied to the surface of the plywood, and then a chipboard-containing cement board is attached to the surface of the plywood. It is nailed to the joist through the cement.

[0005]

However, according to the first means, the worker must apply the elastic adhesive using a caulking gun, and must apply a spatula after the application. The work becomes complicated because it is not performed. Moreover,
Since it takes time to completely bond, it takes time to laminate face materials. In addition, there is also a problem that it cannot be machined because it must be flattened after the application. In the second means, the plywood is first attached, and then the cement plate is adhered. Therefore, the work is complicated, lamination by press cannot be performed, and the number of on-site work increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a laminated panel capable of easily laminating a plurality of face materials in a short period of time, requiring less on-site work, and preventing warpage and peeling, and a method of manufacturing the laminated panel. It is in.

In the above, the two-part curable adhesive is:
The main agent, the curing agent, the catalyst and the like are used as the first and second liquids,
It refers to an adhesive which is present in the form of a liquid and separated, and which is used to mix and cure a predetermined amount of the first liquid and the second liquid when used.
For example, a three-dimensional curable adhesive that immediately reacts when mixed at room temperature corresponds to the adhesive. Representative examples of the three-dimensional curable adhesive include (1) epoxy / amine, amide thiol-based, (2) urethane-based polyisocyanate / polyol, and (3) first reactive acrylic adhesive.

And so on. A two-part curable adhesive also includes a high-temperature curable thermosetting adhesive which does not immediately react even if mixed at room temperature but reacts gradually with the passage of time. In this case, the main agent is the first liquid and the curing agent is the second liquid.
In some cases, the main agent and the curing agent are divided into a first liquid and the accelerator is divided into a second liquid. In addition, if the first and second liquids are made into one liquid, the viscosity increases, and it is preferable to use two liquids if the liquid does not work as an adhesive during use.

Further, the first and second face members may each be a single face member, or one piece obtained by joining two face members in advance, and this face member may be replaced with another single piece of material. And the case where the surface member is joined. Further, the linear application of the first liquid and the second liquid does not necessarily have to be a continuous straight line, but may be, for example, linear and discrete, that is, connected in a bead shape.

In the present invention, if the first and second face materials are bonded together, the first and second liquids of the two-component curable adhesive applied to the respective mating surfaces react and cure. Therefore, a plurality of face materials can be easily laminated in a short time. In addition, since the first and second liquids need only be applied in a straight line, it is not necessary to apply the first and second liquids after application, so that mechanization becomes possible, which also enables lamination of a plurality of face materials in a short time.

From the paneling process, it can be sent to another process unit, for example, a storage unit. In the paneling process, the next surface materials can be bonded together, so that a plurality of surface materials can be easily laminated in a short time. .

In the present invention, as shown in FIG. 2, a plurality of rows of the first and second liquids 5A and 5B may be applied respectively, and the interval between straight lines of these liquids may be about 10 cm.

In the above, the interval between the first and second liquids is 10
The width dimension of each liquid itself may be arbitrary as long as it is about Cm, but it is necessary to have a width dimension that can secure strength capable of preventing warpage and peeling after lamination of the first and second face materials. is there. According to the present invention, an initial hardened portion is formed at the intersection of about 10 Cm on the mating surface of the first and second face materials, so that the lamination can be performed in a short time, and the portion other than the intersection is crushed. The liquids protruding from the intersections react and harden with each other, so that the liquids become stronger, thereby preventing the laminated panel from warping or peeling.

Further, the method for manufacturing a laminated panel according to the present invention comprises:
Referring to the drawings, as shown in FIG.
A method of manufacturing a laminated panel 1 by bonding second face materials 2 and 3, wherein a first and second liquid of a two-component curable adhesive 5 is applied to a mating surface 2 </ b> A of the first face material 2. One of the liquids 5A and 5B is applied in a plurality of rows by an adhesive application device 10 that applies a plurality of rows simultaneously and linearly, and the first and second liquids 5A are applied to the mating surface 3A of the second face material 3. , 5B, the other liquid
It crosses with one of the liquids and is applied in a plurality of rows by the adhesive application device 10, and thereafter, the respective mating surfaces 2A and 3A of the first and second face materials 2 and 3 are combined and pressed in a pressing process, It is characterized in that the two-sided materials 2 and 3 are joined.

In the above, the adhesive applying device is, for example, a moving object moving with respect to a bed of a machine tool.
With a general drive mechanism, it is movable along the mating surface of the first and second face materials, and for example, a plurality of nozzles are provided at intervals of 10 Cm and supplied from respective tanks for supplying the first and second liquids. It is preferable that the applied liquid is discharged and applied simultaneously in a plurality of rows.

According to the present invention, the first and second face materials in which one or the other of the first and second liquids of the two-component curable adhesive is applied to the respective mating surfaces are provided. Since it is only necessary to bond together, a plurality of face materials can be easily laminated in a short time. Also, since the first and second liquids can be applied to the mating surfaces of the face materials with an adhesive application device capable of simultaneously applying a plurality of rows,

A plurality of tip nozzles 13 including the tip nozzles at both ends are provided. Each liquid is sent to the nozzle body 12 from an adhesive supply tank (not shown) for the first liquid 5A and the second liquid 5B by a pump (not shown) or the like. The interval between the tip nozzles 13 is, for example, 10 cm.
It has become about.

As described above, since the liquid is applied to the mating surface 3A of the second face material 3 orthogonally to the first face material 2,
The adhesive application device 10 is moved along the width direction of the face material 3. In this case, the adhesive application device 10
Since the length dimension of the nozzle body 12 is equal to the width dimension of the face material 3 or the like, the nozzle body 12 may be reciprocated twice, for example. The bonding and integration of the face materials 2 and 3 to which the two-component curable adhesive 5 is applied is performed using a face material pressing device (not shown).

Next, a method of manufacturing a laminated panel according to the present invention will be described. First, the first face material 2 is placed on the base 11 with its mating face 2A facing upward, and the mating face 2
