Abstract

PROBLEM TO BE SOLVED: To efficiently and reliably effect a pattern transfer against a column base using a wrapping lamination machine by a method wherein a non-cured ionizing radiation curable resin is applied, formed and stacked to a column base before the resin is cured at a partly cured surface of the transfer sheet. SOLUTION: A transfer sheet 11 is so structured that a pattern layer and a partly cured ionizing radiation curable resin layer 4 are stacked through a stripped layer at one surface of a base sheet 10. At a stage this transfer sheet is carried at a synchronous speed as the column base material, a non-cured ionizing radiation curable resin is applied and formed at a partly cured surface of the transfer sheet or an outer surface of the column base. While this resin is not cured, a partly cured side of the transfer sheet 11 is set an outer surface side of the column base and stacked by using a roller. Further, after the ionizing radiation is irradiated from the transfer sheet side to be integrally cured, the base sheet 10 is stripped. Thereby, a surface strength is increased and can be reliably effected a lamination by the transfer.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring a pattern to a column-shaped substrate, and more particularly to a method for transferring a pattern to a column-shaped substrate used as a building material such as a window frame or a sill and having an irregular surface or a curved surface. To a manufacturing method suitable for performing the method.

[0002]

2. Description of the Related Art Conventionally, a long object having a woody base material such as natural wood, plywood or the like, which has an irregular or curved surface, is provided with an appropriate pattern on an outer surface thereof. It is widely used as a building material such as handrails or as a component member such as furniture. As means for applying a pattern to the columnar base material, the columnar base material is fixed and arranged, and the heat transfer sheet is formed in a columnar shape with the transfer layer side facing the columnar base material side which is the base material to be transferred. After overlapping on the base material and heating the transfer sheet with a heating roll, only the thermal transfer sheet is peeled off,
The so-called thermal transfer lamination method of transferring the transfer layer onto the columnar substrate, or a painting method using a lapping laminator, while the columnar substrate travels in its longitudinal direction,
A printing ink is adhered to one side of a flexible band-shaped sheet according to a desired design, and the ink-applied surface of the sheet is pressed against the outer surface of the substrate while the ink is in an undried state. A so-called in-line transfer method in which a sheet is fed at the same speed in the same direction as the substrate and the ink is transferred to the outer surface of the columnar substrate using the adhesive force, and then the sheet is peeled off from the substrate (Japanese Patent Publication No. -2666 publication) and the like.

In a conventional method, a thermal transfer laminating method in which a columnar substrate is fixed and arranged, and a thermal transfer sheet is superposed thereon and a pattern is transferred generally uses a hot-melt adhesive as an adhesive. In addition, the configuration of the transfer sheet becomes complicated, and a large amount of heat is required for melting the adhesive, so that the power consumption is large and the cost is high. Furthermore, painting can be performed on a flat base material by good transfer, but it is difficult to paint on a base material having complicated irregularities or curved surfaces.

In a painting method using a lapping laminating machine, an in-line operation can be performed, and a pressing roll for pressing or guiding a transfer sheet to a columnar substrate having a complicated surface shape can be used. This is an effective method since it is possible to perform good painting by appropriately selecting the shape and the mounting position, but it has some disadvantages. For example, in this method, basically, a printing pattern is transferred using the adhesive force while the printing ink is uncured or the solvent is not dried, and within a short time after printing the pattern on the release sheet. It is necessary to perform the transfer. As a result, it is difficult to inspect the quality of the pattern and to remove the defective pattern when it occurs, and a columnar substrate to which the defective pattern is transferred is manufactured. Costs increase with the loss of resources. Further, since the printing ink or the solvent is not cured at the time of transfer, the pattern flows due to the pressure at the time of transfer, and defective products due to deformation or bleeding of the pattern are likely to occur.

Accordingly, the present inventors have proposed a method of transferring a picture to a columnar base material which solves the above-mentioned drawbacks, as disclosed in Japanese Patent Application No. Hei.
No. 210483 was filed. Although the above-mentioned various disadvantages were solved by such a method, when a thermosetting resin was used as the curable resin adhesive, it was necessary to use a very high temperature during the transfer and pressurize for a certain period of time. However, it is not suitable for wrapping applications such as the present invention, and when using an ionizing radiation-curable resin, it fills the irregularities of the base material and can transfer the pattern layer of the transfer sheet. It is necessary to apply a very large amount of uncured ionizing radiation-curable resin in order to do so, but since the amount of application that can be applied at a time is limited, wrapping applications such as the present invention that are continuously produced In addition, it is not suitable for use, and when the coating amount is large, it becomes necessary to make the irradiation ability of the ionizing radiation to be hardened very large, so that there has been a problem that it is very difficult and the cost is greatly increased. Also,
It is also conceivable to use a two-part curable adhesive made of urethane resin or the like, but in that case, the urethane resin is soft and has low surface strength, so it is vulnerable to impact and is easily scratched. In addition, since it takes 1 to 3 days for the urethane resin to completely cure, the transfer sheet cannot be peeled off, and furthermore, drying is required before lamination at the time of transfer. Was bad.

The structure of the columnar substrate 1 with a picture of the present invention is shown in FIG.
A transfer sheet 11 having a structure in which a pattern layer 5 and an ionizing radiation-curable resin layer 4 partially cured in a touch-dry state are sequentially laminated on one surface of a transfer base material sheet 10 shown in FIG. As shown in FIG. 2, the ionizing radiation-curable resin layer 3 applied to the surface of the columnar base material 2 in an uncured state and a partially cured touch-transferred state transferred from the transfer sheet 11 are used. The pattern layer 5 is provided via a cured adhesive layer 7 made of an ionizing radiation-curable resin layer 4 ′, and a surface protective layer 8 is provided so as to cover the entire surface of the pattern layer 5. Here, for the sake of convenience, the cured adhesive layer 7 is formed by separating the ionizing radiation-curable resin layer 3 applied in an uncured state and the ionizing radiation-curable resin layer 4 ′ partially cured in a touch-dry state. Although it is shown, it is actually one that is hardened integrally.

Next, as a method of manufacturing the columnar substrate 1 with a picture, an apparatus as shown in FIGS. 3 to 5 is used.

In a state where the transfer sheet 11 is in close contact with the entire length of the columnar substrate 2, the columnar substrate 2 is moved to the next belt conveyor 12.
a.

FIG. 4 shows an example in which the lapping laminating machine shown in FIG. 3 is used for carrying out the method of transferring a picture to a columnar substrate according to the present invention. That is, the transfer sheet 11 prepared in advance attached to the take-up roll 20 passes through the feed roll 31 rotating at the same peripheral speed as the feed speed of the columnar base material 2 and the guide roll 32, and the transfer base sheet 10 in FIG. It is fed between the impression cylinder 33 and the coating roll 34 with the upper surface as the transfer layer and the lower surface. The coating roll 34 is immersed in the uncured ionizing radiation-curable resin 40 in the ink pan 35, and is rotated by rotating the coating roll 34.
The uncured ionizing radiation-curable resin 40 in 5 is pulled up. The lifted ionizing radiation-curable resin 41 is adjusted to a predetermined thickness by the measuring roll 36, and then applied as an ionizing radiation-curable resin layer 3 to the transfer layer side of the transfer sheet 11. In addition, this coating means shows only an example,

The amount of the photoinitiator added is generally 0.1 to 100 parts by weight of the ionizing radiation-curable resin.
It is about 1 to 10 parts by weight.

The ionizing radiation R used in the present invention means an electromagnetic wave or a charged particle beam having an energy quantum capable of polymerizing and cross-linking a molecule, such as visible light, ultraviolet (near ultraviolet, vacuum ultraviolet) X-ray, There are an electron beam and an ion beam. Usually, ultraviolet rays or electron beams are used. Ultraviolet light sources, high pressure mercury lamps, low pressure mercury lamps, carbon arc lamps, black light fluorescent lamps, and metal halide lamp lamps can be used as the ultraviolet light source. As the wavelength of the ultraviolet light, a wavelength range of 1900 to 3800 ° is mainly used. Also, as the electron beam source, various electron beam accelerators such as Cockloft-Walton type, Van degraft type, Resonant transformer type, Insulating core transformer type, or linear type, Dynamitron type, high frequency type lamp, Irradiation with electrons having an energy of 1000 KeV, preferably 100 to 300 KeV can be used. Upon irradiation with ionizing radiation, the ionizing radiation-curable resin undergoes a cross-linking polymerization reaction and changes to a three-dimensional polymer structure.

With respect to the ionizing radiation-curable resin layer 4 provided on the surface of the pattern layer 5 of the transfer sheet 11 and partially cured in a touch-dry state, the resin does not adhere to the finger even when the surface is touched with the finger. This state is obtained by irradiating about 1/3 to 2/3 of the irradiation amount necessary for completely curing the ionizing radiation-curable resin. The ionizing radiation-curable resin layer 4, which has been partially cured to the touch-dry state, has a polymerization inhibition of hydroquinone, hydroquinone monomethyl ether, benzoquinone, etc. in order to suppress dark reactions and increase stability during storage. It is preferable to add the agent at a ratio of 10 parts by weight or less.

Further, titanium white is used as the ionizing radiation curable resin,
Inorganic pigments such as carbon black, graphite, chromium vermillion, cadmium red, navy blue, ultramarine blue, iron oxide, and alumina white; and organic pigments such as azo pigments, azo lake pigments, sulene pigments, and quinadrine pigments By containing a coloring agent, the underlying columnar substrate can be concealed and a free pattern can be applied irrespective of the color and pattern of the columnar substrate, and further, calcium carbonate, talc, clay, and so on can be applied. By adding an extender pigment such as that described above, the thickness of the ionizing radiation-curable resin layer can be felt, and the wood grain conduit of the columnar substrate can be given a sense of depth. However, when using an ultraviolet curable resin, if the coloring agent is added to conceal the base, the curing of the resin may be hindered. It is a good method not to include in the cured ionizing radiation-curable resin layer 4 ', but to include in the ionizing radiation-curable resin to be applied and formed at the time of transfer.

The transfer substrate sheet 10 used for the transfer sheet 11 of the present invention may be any material as long as it can transmit the ionizing radiation to be used, and any material that can be released from the cured ionizing radiation-curable resin. . When the ionizing radiation is ultraviolet, polyethylene,
Polyolefin resins such as polypropylene and polymethylpentene, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, vinyl resins such as vinylon, polyethylene terephthalate, polybutylene terephthalate , Polyester resins such as polyethylene naphthalate-isophthalate copolymer, acrylic resins such as polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, polybutyl acrylate, and polyamides such as nylon 6 and nylon 66 , Cellulose triacetate, cellulosic resins such as cellophane, stretched films or sheets such as polystyrene, polycarbonate, polyarylate, polyimide, etc., and coloring agents that inhibit ultraviolet light transmission. Those that do not contain is preferable. When the ionizing radiation is an electron beam, there is no particular limitation because the electron beam has high transparency, and it can be used not only for the above-mentioned sheet transmitting ultraviolet rays but also for paper. Therefore, it is possible to make a selection focusing on the suitability for printing and the suitability for transfer, and the thickness of the transfer base sheet 10 is preferably 5 to 200 μm. In addition, as a release layer provided as needed,
A release agent alone such as a polyolefin resin, a silicone resin, and a fluorine-based resin, or a coating film of a paint in which these are added to a known vehicle can be used. Further, the release layer may have a releasability from the transfer substrate sheet, and may be laminated as a surface protective layer of the transfer layer after the transfer is completed, in which case a resin material having desired physical properties may be used. It is formed by selection.

[0025] While the separation of the transfer base sheet 10 can be carried out by any means, FIG plurality of the pressing rolls r ₁ ~r _n corresponding to the shape of the outer surface of the columnar base material 2 as shown in FIG. 5 By arranging in the reverse order to the case of the sticking shown in FIG. 3 and sequentially peeling off from the side portions of the columnar base material 2, it is possible to peel cleanly without breaking the sheet and without disturbing the pattern. I can do it. The columnar base material from which the transfer base material sheet 10 has been peeled off is taken out of the conveyor 12a as a picture-formed columnar base material 1 onto which the cured adhesive layer 7 and the picture layer 5 have been transferred.

The same purpose can be achieved by applying the uncured ionizing radiation curable resin 40 to the outer surface of the columnar substrate 2 instead of the transfer sheet surface as described above. . In this case, the coating means such as an ink pan is removed from the contact device shown in FIG. 4, and instead, the coating device is placed at a position immediately before the columnar substrate 2 is sent to the contact device as shown in FIG. So that the columnar substrate 2 passes through the coating means. FIG. 6 shows a spraying means as a coating means. The coating is performed by spraying an uncured ionizing radiation-curable resin 40 onto the columnar base material 2 from a spray nozzle 61 opened in the coating chamber 60. Do.

The cross-sectional shape of the columnar substrate transferred by the method of transferring a picture according to the present invention is not particularly limited, and a transfer sheet is pasted on the outer surface thereof by a conventionally known lapping laminating machine (curved laminating machine). Any cross-sectional shape that can be worn is acceptable. The material is also optional. Metal materials such as iron and aluminum, synthetic resin materials such as polyvinyl chloride and acrylic resin, or wood-based base materials such as plywood, particle board, MDF, and ceramic product base materials such as ceramics For example, any material can be selected in accordance with the desired final product.

Example 1 An acrylic resin (VAGH matt media, manufactured by Showa Ink) was applied to a stretched polypropylene film having a thickness of 25 μm to form a release layer, and a vinyl chloride-vinyl-acrylic ink (manufactured by Showa Ink) was formed thereon. , X), a wood grain pattern layer and a polyester-based UV-curable resin are sequentially laminated by a gravure printing machine, and then UV irradiation is performed so that the polyester-based UV-curable resin is partially cured to a touch-dry state. Thus, a transfer sheet was prepared. Next, a knife coater is positioned in the middle of the transfer sheet transfer path of a commonly used curved laminator (PL-300C manufactured by Marunaka Shoji), and a polyester-based ultraviolet curable resin is used as an adhesive on the transfer layer surface of the transfer sheet. Coating (Coating amount: 80 g / m ² )
did. Curved laminate (speed: 20 m / mi) on MDF substrate processed into desired shape from transfer sheet coated with adhesive
n, drying temperature: 60-70 ° C, wrapping temperature: 60-
(70 ° C.), and then irradiated with ultraviolet light to completely cure the ultraviolet-curable resin as an adhesive and the ultraviolet-curable resin partially cured to a touch-dry state. After the adhesive was cured, only the transfer substrate sheet was peeled off, and after the peeling, the substrate was painted with a urethane-based paint to obtain a columnar substrate with a pattern that reproduced the shine of natural wood.

[0029]

As described above, according to the method of the present invention, the surface strength is high, the impact resistance and the scratch resistance are excellent,
In addition, it is possible to obtain a columnar substrate excellent in productivity, which can perform painting by transfer reliably, is quick-drying, and can be easily peeled from a transfer sheet substrate.
