Description

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, paper fibers are easily separated from each other inside the paper, so that the base film is easily peeled off.

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, after the transfer material and the polyhedral transferred material are superposed, the adhesiveness of the adhesive layer is eliminated,
Furthermore, the adhesive layer is completely cured, and the transfer material and the polyhedral transferred material are completely adhered to each other to complete the product, but it takes a long time of about 3 or 4 days. Therefore, the production efficiency is poor. Further, if the base sheet is peeled off while the curing of the adhesive layer is incomplete, the transfer layer will peel off together with the base sheet. Even if the transfer layer does not peel off together with the base sheet, the adhesive layer that is incompletely cured is soft, so when the transfer material is gripped by hand, the transfer layer and the polyhedral transfer material are manually pressed. It was difficult to handle because there was a gap at the interface with the.

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, it is to provide a method for producing a transfer product capable of quickly and completely curing the adhesive layer.

[0011]

In order to achieve the above object, the method for producing a transfer product of the present invention has the following construction. That is, in the method for producing a transfer product of the present invention, an adhesive layer made of an ionizing radiation curable resin is formed on a design layer of a transfer material having a transfer layer in which a release layer and a design layer are sequentially formed on a base sheet. Then, the adhesive layer of the transfer material is superposed on the transfer target and pressed to bond the transfer material and the transfer target, and the adhesive layer is cured by irradiation with ionizing radiation, and the base sheet is removed. The transfer layer was formed on the surface of the transfer material.

According to the method for producing a transfer product of the present invention, an adhesive layer made of an ionizing radiation-curable resin is formed on a transfer product, and a transfer layer is formed on a base sheet in which a release layer and a pattern layer are sequentially formed. The pattern layer of the transfer material is superposed on the transfer target and pressed, the transfer material and the transfer target are adhered, and the adhesive layer is cured by irradiating ionizing radiation to remove the base sheet, and the surface of the transfer target. The transfer layer is formed on the substrate.

In the method for producing a transfer product according to the present invention, at the time of pressurizing, 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 press roll for one surface, 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.

According to the method for producing a transfer material of the present invention, an adhesive layer is formed on a plurality of surfaces of a polyhedral transferred material, and at the time of applying the pressure, first, a part of the pattern layer of the transfer material is applied to one surface of the polyhedral transferred material. It is configured such that it is superposed on the above and is pre-pressed by a press roll for one surface, and then another portion of the pattern layer of the transfer material is superposed on the other surface of the transferred material and is post-pressed by the press roll for other 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.

The transfer material 1, the transfer device, and the transferred object 2
And prepare.

The transferred material 2 includes laminated wood formed by joining wood pieces of unit size, plywood, an inorganic material such as aluminum, and a plastic material, and includes a thin plate and a three-dimensional object.

As the three-dimensional object, a plate-like object having a rectangular cross section having an upper surface, a lower surface, a right side surface, and a left side surface (Fig. 4), or a rod-shaped object having a trapezoidal cross section having an upper surface, a lower surface, a right slope, a left slope, a right side, and a left side. (FIG. 5), a rod having a substantially trapezoidal cross section in which the upper surface and the right side surface, and the upper surface and the left side surface are smoothly curved and connected (FIG. 6), and a substantially boomerang cross section having a concave upper surface and a convex lower surface. 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.

The transfer material 1 shown in FIG. 1, the transfer device shown in FIGS. 2 and 4, the upper surface, the lower surface, the right side surface, and the left side surface shown in FIG. A case will be described in which a polyhedron transferred object including a plate-shaped object having a rectangular cross-section is used.

First, an adhesive layer 16 made of an ionizing radiation curable resin is formed on the pattern layer 12 of the transfer material 1 (FIG. 2).

That is, the transfer material 1 is sent from the sending roll magazine 20 so that the pattern layer 12 faces upward,
Move to the underlay plate 32 when forming the adhesive,
The adhesive 17 is formed on the design layer 12 by application, printing, brush coating, dispenser or the like while continuously or intermittently moving to form the adhesive layer 16. This adhesive 17
Suitably has a viscosity of 3000 to 10000 CPS. 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 an ionizing radiation curable resin,
It is a resin that cures when irradiated with ionizing radiation such as ultraviolet rays, electron rays, X rays, α rays, β rays, and γ rays. As the ionizing radiation curable resin, acrylic ultraviolet curable resin, acrylic electron beam curable resin, acrylic X ray curable resin, acrylic α ray curable resin, acrylic β ray curable resin, acrylic γ ray There are curable resins. The ionizing radiation-curable resin is a resin that does not have a solvent, but has fluidity or adhesiveness such that it does not spill even after it is formed on the pattern layer 12. A solvent may be contained if necessary, but in this case, a drying step is required after forming the adhesive layer 16. The adhesive layer 16 made of an ionizing radiation curable resin has a low solvent content and is immediately dried.

As the ultraviolet curable resin, a composition of a prepolymer or oligomer having a polymerizable double bond,
Alternatively, there is a composition in which a reactive diluent and a photopolymerization initiator are mixed in a composition of a prepolymer or an oligomer having an epoxy group. 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. Specifically, a prepolymer or oligomer having an ethylenically unsaturated bond, for example, one or more kinds of unsaturated polyesters, various acrylates, methacrylates and the like, and a monomer having an ethylenically unsaturated bond in the molecule For example, there is a mixture of styrene-based monomers, acrylic acid esters, methacrylic acid esters and the like.

The thickness of the adhesive layer 16 is preferably 1 μm to 80 μm. When the material to be transferred 2 has a relatively smooth surface condition such as plastic or metal, the adhesive 17 is less likely to be absorbed in the material to be transferred 2, so the film thickness is 2 μm to 20 μm. It is good to When the material to be transferred 2 is a relatively rough surface such as a wooden member or has a water-absorbing surface state, the adhesive 17 is easily absorbed in the material to be transferred 2, so that the film thickness is It is preferable that the thickness is 30 μm to 80 μm.

Next, the adhesive layer 16 of the transfer material 1 is superposed on the transfer material 2 and pressed to bond the transfer material 1 and the transfer material 2 (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 below 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. The applied pressure is preferably 0.5 Kg / cm ^{2 to} 10 Kg / cm ² . The pressurizing time is preferably 0.5 seconds to 5 seconds.

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 adhesive layer 1 is irradiated with ionizing radiation.
Cure 6 The ionizing radiation includes ultraviolet rays, electron beams, X-rays, α emitted from the ionizing radiation irradiation means 9.
There are rays, beta rays, and gamma rays.

At this time, when any one of the transfer layers 15 of the transfer material 1 contains an ionizing radiation curable resin, the adhesive layer 16 is cured and the transfer layer 15 is also cured at the same time. You can be efficient. Also,
Since the peeling layer 11 or the pattern layer 12 becomes hard, a very hard surface can be formed on the transferred object 2 although it is the transfer layer 15 which is a very thin layer.

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.

As described above, in the present invention, the pattern layer 1 of the transfer material 1
Instead of forming the adhesive layer 16 on the transfer target 2, the adhesive layer 16 may be formed on the transfer target 2. Adhesive layer 16 in this case
The material, the method of formation, the method of superposing the transfer material 1 on the transferred material 2 and the method of removing the base sheet 10, and the like in the case of forming the adhesive layer 16 on the pattern layer 12 of the transfer material 1. Same as the description.

In the method of manufacturing a transfer material according to the present invention, after the transfer material and the transfer material are adhered to each other, the base sheet is removed and a transfer layer is formed on the surface of the transfer material. 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 transfer product of the present invention, a transfer material having a transfer layer in which a release layer and a pattern layer are sequentially formed on a base sheet is used, and before the transfer material is superposed on the transfer target, An adhesive layer made of an ionizing radiation curable resin is formed in advance. The adhesive layer made of an ionizing radiation-curable resin is tacky, and furthermore, when the ionizing radiation is applied to the adhesive layer, it is completely cured in a short time of about several seconds. Therefore, it takes no time to completely cure the adhesive layer made of the ionizing radiation curable resin.

Further, since the adhesive layer made of the ionizing radiation-curable resin is tacky, even if a polyhedron that requires transfer to a plurality of surfaces is adopted as the transferred material, each surface that can be installed in the transferred material feeding device. Even if the number of press rolls for use is limited and the number of times of pressurization is reduced and the adhesive force is weakened, it is possible to cover the weak point that the adhesive force is weakened due to the decrease of the number of pressurizations.

Further, in the method for producing a transcript of the present invention,
It is also possible to use a transfer material in which at least one layer of the transfer layer is made of an ionizing radiation-curable resin, and at least one layer of the transfer layer and the adhesive layer are irradiated with ionizing radiation to be cured. Therefore, a transfer product having a high surface hardness can be obtained.

[0054]

Since the method for producing a transcript of the present invention has the above-described structure and operation, it has the following effects. 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. Further, the base film does not peel off.

Further, according to the present invention, since the adhesive layer made of the ionizing radiation curable resin is used, it takes only about a few seconds and a short time to completely adhere the transfer material and the polyhedral transferred material. Efficient.

Further, since the base sheet can be easily peeled off after the adhesive layer is completely cured, the transfer layer is not peeled off together with the base sheet when the base sheet is peeled off. . Further, when the transfer material is gripped by hand, the hand force does not cause displacement at the interface between the transfer layer and the polyhedral transfer material, and therefore the handling is easy.

Further, in the present invention, since the adhesive layer made of the ionizing radiation curable resin is used, the adhesive force between the transfer layer and the polyhedral transferred material does not become weak, and each surface of the polyhedral transferred material is not weakened. It is possible to sufficiently increase the adhesive force between the transfer layer and the transfer layer.
