Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to interior and exterior materials for construction, surface materials for furniture, surface materials for kitchens, car door members, and plate-shaped, bar-shaped, strip-shaped materials used as rims thereof. The present invention relates to a transfer material for forming a pattern and a method of manufacturing a transfer material using the transfer material.

[0002]

2. Description of the Related Art The following is an example of a conventional method for manufacturing the above-mentioned interior and exterior materials for construction. (1) A long base material film made of vinyl chloride resin, high-quality paper or the like is provided with a design layer to obtain a long laminate material, and an adhesive layer is applied to the side opposite to the design layer of the laminate material. The adhesive layer of the laminating material is superposed on the object to be painted continuously fed to the object to be painted feeding device in a state where the adhesive layer is tacky (also called active state), There is a manufacturing method in which a laminated material and an object to be painted are adhered to each other by pressing with a press roll, and an excessive portion of the laminated material is cut and removed to obtain a laminated material. In this manufacturing method, the article to be painted is continuously fed, so the step of forming an adhesive layer on the laminate material, the step of superposing the laminate material and the article to be painted, and pressing by a rotating press roll. Each process such as a process and a cutting and removing process is performed in a flowable manner while constantly moving the object to be painted.

In this manufacturing method, for example, when a polyhedron requiring lamination on the upper surface and two side surfaces is an object to be painted (hereinafter referred to as a polyhedron object to be painted), the upper surface of the plate-shaped polyhedron. And the two sides are the surfaces that require pressurization. Therefore, a press roll for the upper surface that presses perpendicularly to the upper surface of the polyhedral object, a press roll for one side surface that presses one side surface vertically, and a press roller that presses the other side surface vertically. A total of three types of press rolls including side press rolls are separately prepared and fixedly installed on the polyhedral object feeding device, and the press rolls for each face are pressed against the corresponding pressurizing required faces.

Therefore, for example, when a polyhedron which is required to be laminated on a plurality of surfaces is adopted as an object to be painted, it is necessary to install the press rolls corresponding to the required number of pressing surfaces. As the number of surfaces of the polyhedral object to be pressed increases, it becomes necessary to increase the number of press rolls installed in the object feeding device and to increase the pressing time.
However, since the size of the object-to-be-painted feeding device is limited, the number of press rolls for each surface that can be installed in the object-to-be-painted feeding device is also limited. Therefore, the greater the number of pressure-required surfaces of the polyhedral object to be coated, the smaller the number of pressurization to each pressure-required surface, and the weaker the adhesive force between the laminate material and the polyhedral object to be coated.

In the manufacturing method of (1), since the laminating material and the polyhedral object to be painted are adhered while the adhesive layer is in a sticky state, the disadvantage that the adhesive force is weakened is compensated. The adhesive force between the material and the polyhedral object to be painted can be made sufficient.

(2) In the manufacturing method of (1) above, a method of using a transfer material having a transfer layer in which a release layer and a pattern layer are sequentially formed on a long base sheet can be considered. That is, an adhesive layer is formed on the pattern layer of the transfer material, immediately dried to remove tackiness, and then the adhesive material of the transfer material is applied to the transferred material continuously fed to the transferred material feeding device. After stacking the layers, heating and pressing are performed at the same time with a heated press roll to restore the tackiness of the adhesive layer and bond the transfer material and the transfer target, and then peel the base sheet. Then, there is a manufacturing method in which a transfer layer is formed on the surface of the transferred material to obtain a transferred material.

Comparing (1) and (2) above,
As in (2), a method of laminating on an object to be painted as in (1) rather than a manufacturing method in which the adhesive layer of the transfer material is superposed on the object to be transferred and then the adhesiveness of the adhesive layer is restored Generally, the adhesive force is stronger in the manufacturing method in which the adhesive layer is in a tacky state before the materials are stacked.

[0008]

However, in (1),
After laminating the laminating material on the article to be painted, the base film is not peeled off, and the finished product is obtained in a state where the base film remains on the article to be painted. For this reason, only the surface state of the substrate film that has a gloss and a touch is a finished product, and a finished product that utilizes the surface state of the material itself to be painted cannot be obtained. Also,
In (1), when the object to be painted encounters a fire, the base material film made of vinyl chloride resin burns to generate harmful black smoke, which is a problem in disaster prevention. Also, (1)
Then, when a base film made of high-quality paper is used, peeling between paper fibers easily occurs inside the paper.

In addition, in (2), in order to compensate for the disadvantage that the adhesive force between the transfer material and the transferred material of the polyhedron becomes weak,
Before the transfer material is superposed on the transfer object by applying the manufacturing method of (1), the adhesive layer has a tacky state, for example, a state where the adhesiveness is restored by heating, or the adhesive layer is removed. It is conceivable to keep the stickiness without drying. However, in this case, the solvent of the adhesive layer dissolves the resin of the design layer and destroys the design,
A clean pattern could not be formed on the surface of the transferred material.

The object of the present invention is to obtain a finished product that makes use of the surface condition of the material to be transferred.
Moreover, even if the adhesive layer is activated before the transfer material is superposed on the transfer object, the solvent of the adhesive layer does not destroy the design, and the transfer material manufacturing method, the transfer material, and the transfer material. To provide a device.

After pressing, the primer layer of the transfer material and the transfer target are adhered, the base sheet is removed, and the transfer layer is formed on the surface of the transfer target.

According to the method for producing a transfer product of the present invention, an adhesive layer is formed on a transfer target, the adhesive layer is activated, and then the primer layer of the transfer material is superposed on the adhesive layer of the transfer target. After pressurizing together, the primer layer of the transfer material and the transfer target were adhered to each other, then the base sheet was removed, and the transfer layer was formed on the surface of the transfer target.

In the method for producing a transfer material of the present invention, at the time of the pressing, first, a part of the adhesive layer of the transfer material is superposed on one surface of the transferred material of the polyhedron and prepressed by a one-side press roll, and then, The other part of the adhesive layer of the transfer material is superposed on the other surface of the transferred material, and is post-pressed by the other surface press roll.

One end of a rotary shaft 60 of the press roll is attached to the tip of the support arm 6. The support arm 6 is attached to an arbitrary position such as an upper end, an intermediate position or a lower end of a plurality of upright fixing rods (not shown) provided on the base 5 of the transferred material feeding means at an arbitrary attachment angle. To be The orientation of the press roll can be changed by adjusting the mounting angle. For example, of the surface of the polyhedral transferred material,
When transfer is required on the upper surface, the right side surface, and the left side surface, by adjusting and setting the mounting angle of the support arm 6, the upper surface press roll that presses vertically to the upper surface and one side surface are pressed. It is possible to separately prepare a total of three types of press rolls, that is, one side press roll that presses vertically with respect to the other side, and the other side press roll that presses against the other side face perpendicularly. The press roll is made of rubber, silicon, metal, plastic, or the like.

When the surface of the material to be transferred 2 that is required to be transferred is a concave surface, the surface of the press roll is preferably a convex surface that matches the concave surface.

The transfer material feeding means is composed of a transfer material feeding means and a transfer material winding means, and is a means for feeding and winding the transfer material 1 between the transferred material 2 and the press roll. As an example, as shown in FIG. 2, there is a delivery roll magazine 20 as the transfer material delivery means. A take-up roll magazine 24 is provided as a transfer material take-up unit that winds the transfer material 1 after the transfer material 2 is transferred. The transfer material feeding means further includes a first turn roll 21, a second turn roll 22 and a third turn roll 23 for appropriately changing the traveling direction of the transfer material 1 fed from the feed roll magazine 20.

There are a rod-shaped material (FIG. 7), a plate-shaped material having unevenness on the upper surface and / or side surface (FIG. 9), or a plate-shaped material having a plurality of flat surfaces and curved surfaces. When a metal material such as aluminum is used as the material of the transferred material 2, there are a metal material formed into a tubular shape and a material having a bent edge (FIG. 8). The plate-like material may have a strip shape, a rod shape, a long plate shape, or the like. There are plate-shaped objects with a length of several tens of centimeters to several meters,
The width of the plate-like material ranges from several cm to several hundred cm. Depending on the transfer machine, the width of applicable plates is 20 cm, 30 cm, 45
Some are limited to cm, 60 cm, etc.

A case will be described in which a polyhedron transferred object including a plate-shaped object having a rectangular cross-section is used.

First, the adhesive layer 16 is formed on the primer layer 14 of the transfer material 1 (FIG. 2).

That is, the transfer material 1 is fed out from the roll magazine 20 so that the primer layer 14 faces upward, and is moved onto the plate 32 which serves as the underlay when the adhesive is formed. Primer layer 1 by coating, printing, brush coating, dispenser, etc.
The adhesive 17 is formed on the surface 4. The adhesive layer 16 may be formed on the entire surface of the primer layer 14 of the transfer material 1, or may be formed only on a necessary part. The material of the adhesive is acrylic resin, ethylene vinyl acetate copolymer, polyamide resin, ethylene butyl alcohol resin or urethane resin,
Some are composed of a resin such as a two-component curing type resin and a solvent. Further, for example, there are thermosetting resins, two-component curing resins, ionizing radiation curing resins, and the like, and a solvent may be added if necessary. Examples of the thermosetting resin include acrylic thermosetting resin and melamine thermosetting resin.
Examples of the two-component curable resin include urethane-based two-component curable resin and polyester-based two-component curable resin. As the ionizing radiation curable resin, an acrylic ultraviolet curable resin, an acrylic electron beam curable resin, an acrylic X ray curable resin, an acrylic α ray curable resin, an acrylic β ray curable resin,
Examples include acrylic γ-ray curable resins. As the electron beam curable resin, there is a composition of a prepolymer or oligomer having a polymerizable double bond, or a composition of a prepolymer or oligomer having an epoxy group and a reactive diluent mixed therein. As the UV curable resin, a composition of a prepolymer or oligomer having a polymerizable double bond, or a composition of a prepolymer or oligomer having an epoxy group, mixed with a reactive diluent and a photopolymerization initiator There is. Examples of the solvent include toluene, methyl ethyl ketone, ethyl acetate and the like.

The thickness of the adhesive layer 16 is appropriately 1 μm to 80 μm. When the material to be transferred 2 has a relatively smooth surface state such as plastic or metal, the adhesive 17 is less likely to be absorbed, so the film thickness is 2 μm.
It is good to set it to m to 20 μm. Further, when the material of the transferred material 2 is a relatively rough surface such as a wooden member or has a water absorbing surface state, the adhesive 17 is easily absorbed,
The film thickness may be 30 μm to 80 μm.

Next, the adhesive layer 16 is activated (FIG. 2).

Activating the adhesive layer 16 means, for example, that the adhesive layer 16 is formed on the primer layer 14 of the transfer material 1 until the transfer material 1 is superposed on the transfer object 2. This is to bring the agent layer 16 into a sticky state in which the stickiness is maintained. Alternatively, after the adhesive layer 16 is formed on the primer layer 14 of the transfer material 1, the tackiness is once removed by natural drying or the like, and the tackiness is restored by forced heating to restore the tackiness.

Adhesive layer 16 for maintaining stickiness
Examples of the material include a resin such as an acrylic resin, an ethylene vinyl acetate resin, or a urethane resin to which a monomer of the same type as the resin is added. In this way, after the adhesive layer 16 is formed on the primer layer 14, the transferred material 2
It is possible to maintain a thick solution until it is superposed on the substrate, that is, for about 10 seconds to several minutes, and a dry film is not formed. Alternatively, a tackifier such as petroleum resin may be added to the above resin. This makes it possible to maintain a thick and sticky state between the time when the adhesive layer 16 is formed on the primer layer 14 and the time when the adhesive layer 16 is superposed on the transferred object 2, that is, for about 10 seconds to several minutes. it can.

Adhesive layer 16 for regaining tackiness
The material of the acrylic resin, polyamide resin,
There are thermoplastic resins such as urethane resins. As the forced heating, after the adhesive layer 16 in a dry state is melted and softened by far infrared rays or hot air to restore the adhesiveness, the adhesive layer 16 is not dried again in an atmosphere of far infrared rays or hot air. The adhesive layer 16 until it is superposed on the transferred object 2.
Persists stickiness.

When the tackiness is further strengthened or when the tackiness is restored, far infrared rays or hot air may be used. It is advisable to restore the adhesiveness between the first turn roll 21 and the second turn roll 22 or between the second turn roll 22 and the one-side press roll 7.

Next, the adhesive layer 16 of the transfer material 1 is superposed on the transferred material 2 and pressed to obtain the primer layer 1 of the transfer material 1.
4 and the transferred material 2 are adhered (FIG. 2).

That is, the transfer target 2, which is a long strip-shaped plate having an upper surface, a lower surface, a left side surface and a right side surface, is conveyed under the transfer material 1 by a number of pinch rolls 3. The adhesive layer 16 in the tacky state of the transfer material 1 almost comes in contact with the transferred material 2, and then the upper press roll that presses perpendicularly to the upper surface of the transferred material 2 is a one-sided press. As the roll 7, the transfer material 1 is pressed against the upper surface of the tip of the transfer target 2 and pre-pressed. The transferred material 2 is pinched by the pinch roll 3 while the upper surface is pressed by the one-side press roll 7.
The right side press roll that moves upward and then presses the right side surface of the transferred object 2 vertically and the left side press roll that presses the left side surface of the transferred object 2 vertically are the other side press rolls. As 8, the transfer material 1 is pressed against the right side surface and the left side surface of the tip end portion of the transferred object 2 and post-pressurized. After that, the pressing state of the upper surface of the transferred material 2 by the one-side press roll 7 and the pressing state of the right side surface and the left-side surface of the transferred material 2 by the other-side press roll 8 simultaneously continue, and first. The pressing state of the upper surface of the rear end portion of the transferred object 2 by the one-side press roll 7 is released, and then the right side surface and the left side surface of the rear end portion of the transferred object 2 by the other surface press roll 8 are applied. The pressure state is released.

In this example of the method of manufacturing a transfer product, a long strip-shaped plate-shaped product having an upper surface, a lower surface, a right side surface and a left side surface is used as the transfer target, the upper surface is one surface, and the right side surface and the left side surface are other surfaces. However, depending on the order in which the press rolls apply pressure, the left side of the right side and the left side of the transferred material may be one side and the right side may be the other side. Alternatively, the lower surface of the transferred object may be one surface and only the left side surface may be the other surface. Alternatively, the right side surface and the left side surface of the transferred object may be one surface and the upper surface may be the other surface.

The number of pressurizations is 1 for each of the top and side surfaces.
The number of times of pressurization may be only once, or the number of times of pressurization may be two or more for each surface. Each surface may be simultaneously pressed by different press rolls.

Next, the base sheet 10 is removed, and the transfer layer 15 is formed on the surface of the transferred material. That is, as soon as the pressure applied by the press roll 8 for the other surface is released, the base sheet 10 is separated from the transfer target 2 and removed by the third turn roll 23. After that, the base sheet 10 is
It is taken up by the take-up roll magazine 24.

In this embodiment, the bone part design layer, the main part design layer and the lower map design layer are combined to form a design layer.

An adhesive layer having a film thickness of 50 μm was formed on the primer layer of this transfer material using a two-component curing type urethane ink with a knife coater, and the upper surface, the lower surface, the right side surface and the left side surface were formed without being dried. First, the adhesive layer of the transfer material is overlaid on the upper surface of the wood rod (Fig. 4) that has a trapezoidal cross section and is sent at a feed rate of 7 m / min, and is pressed by the upper press roll,
Approximately 1 second later, the adhesive layers of the transfer materials on the right side and the left side are overlapped and pressed by the right side press roll and the press roller for the left side, and after about 1 second, the adhesive layers of the transfer material on the lower side are overlapped The substrate sheet was removed about 2 seconds after the transfer material was pressed by the press roll to be wrapped in the transfer material. The finished transfer product took advantage of the surface condition of the material to be transferred, and the pattern was not destroyed by the solvent of the adhesive layer.

In the method of manufacturing a transfer material, the transfer material and the transfer device according to the present invention, after the primer layer of the transfer material and the transfer material are adhered to each other, the base sheet is removed to form the transfer layer on the surface of the transfer material. To do. Therefore, only the transfer layer covers the surface of the transferred object. Since the transfer layer is formed by a printing method or a coating method, it is a very thin layer as compared with the base material film of the laminate material.

In the method for producing a transferred product, the transfer material and the transfer device of the present invention, a transfer material having a transfer layer in which a release layer, a pattern layer, a solvent resistant layer and a primer layer are sequentially formed on a base sheet is used. Before the transfer material is superposed on the transfer target, the adhesive layer is activated. Therefore, the solvent of the adhesive layer penetrates the primer layer and reaches the solvent resistant layer, but the solvent resistant layer does not penetrate the solvent of the adhesive layer. Therefore, the solvent of the adhesive never reaches the design layer. That is,
The pattern layer is protected from the solvent of the adhesive layer by the primer layer and the solvent resistant layer.

Even when a polyhedron which requires transfer to a plurality of surfaces is adopted as the transferred material, the adhesive force between the transfer material and the transferred material of the polyhedron does not become weak. In other words, the number of press rolls for each surface that can be installed in the transferred material feeding device is limited, and even if the number of pressurizations is reduced and the adhesive strength is weakened, before the transfer material is superposed on the transferred material, The adhesive layer can be left active. Therefore, it becomes possible to cover the weak point of the adhesive force due to the decrease in the number of pressurizations.

[0057]

Since the method for producing a transfer product, the transfer material and the transfer device according to the present invention have the above-mentioned constitutions and functions, the following effects can be obtained. That is, in the present invention, since the surface of the transferred material is covered only by the transfer layer, it is possible to obtain a finished product having the surface condition of the material itself of the transferred material. Moreover, since no harmful black smoke is generated during a fire, there is no problem in disaster prevention. Also, the surface does not peel off.

Further, in the present invention, even when the adhesive layer is activated before the transfer material is superposed on the transferred material, the pattern layer is made of the solvent of the adhesive liquid by the primer layer and the solvent resistant layer. Since it is protected and the pattern is not destroyed, it is possible to form a clean pattern on the surface of the transferred material.

Further, in the present invention, the adhesive force between the transfer layer and the transferred material of the polyhedron does not become weak, so that the adhesive force between each surface of the transferred material of the polyhedron and the transfer layer can be made sufficiently strong. .
