Field of the Invention The present invention relates to an ultraviolet irradiation apparatus for curing an ultraviolet-curable coating layer provided on a plastic film, paper, a release film, a metal foil or the like. . 2. Description of the Related Art An ultraviolet irradiation apparatus continuously cures an ultraviolet-curable coating layer provided on a plastic film, paper, a peeling film, a metal foil, or the like to form a sealing tape, an adhesive tape, a printed material, or the like. Widely used to obtain printed circuit boards and the like. FIG. 2 shows a conventional ultraviolet irradiation apparatus. FIG.
The ultraviolet irradiating apparatus comprises a lamp house 21 and a conveyor belt 23 for conveying a web 22 such as a plastic film provided with an ultraviolet-curable coating layer under the lamp house 21. The lamp house 21 includes a tubular lamp 24, a reflection mirror 25 for condensing ultraviolet rays generated by the lamp 24, and a heat ray cut filter 26 for cutting off light of an unnecessary wavelength. Japanese Patent Application Laid-Open No. H5-50007 proposes an apparatus for propagating ultraviolet rays generated by ultraviolet ray generating means through an optical fiber and uniformly irradiating a web. [0005] A tubular lamp generates ultraviolet light by discharging electrodes at both ends of the tube. For this reason, the intensity of the ultraviolet light is stable at the central portion of the tube, but becomes weaker as it approaches the electrode portions at both ends. In the ultraviolet irradiation apparatus as shown in FIG. 2, since the tubular lamps 24 are arranged so as to be orthogonal to the web 22, the intensity of the ultraviolet light applied to the web 22 is different between the central portion and both sides. Come. For this reason, there is a problem that the cured ultraviolet curable coating layer has a slight difference in characteristics between the central portion and both sides. When irradiation is performed at the center of the tubular lamp in order to obtain a coating layer having uniform characteristics, the effective irradiation width is reduced, and the economic loss is increased. If the length of the tubular lamp is increased, the coating width can be increased. However, a lamp having a long tube consumes a large amount of electric power, shortens the life of the lamp, and increases the size of the apparatus. On the other hand, in Japanese Patent Laid-Open No. 5-50007, the ultraviolet light generated by the ultraviolet light generating means is propagated through a plurality of optical fibers and uniformly irradiates the entire surface of the web, so that a coating layer having uniform characteristics can be obtained. However, there is another problem that the optical fiber is expensive and the intensity is reduced while the ultraviolet light propagates through the optical fiber. The present invention is to solve the above technical problems. Plastic film,
When continuously curing an ultraviolet-curable coating layer provided on paper, a release film, a metal foil, etc., the center portion and both sides of the web are uniformly irradiated with ultraviolet rays, and a cured coating layer having uniform properties. It is an object of the present invention to provide a small and inexpensive ultraviolet irradiation device for obtaining the ultraviolet ray. [0010] To achieve the above object, according to solve the problems, the present invention provides an ultraviolet generating means, and an ultraviolet-curable coating layer provided with ultraviolet rays generated by the ultraviolet rays generating means on the web UV light having a main wavelength of 356 nm by using an ultraviolet irradiation device having a web conveying means for continuously irradiating the web
Was irradiated to the UV-curable coating layer to polymerize about 80%.
After that, ultraviolet rays having a main wavelength of 365 nm are irradiated to cure the ultraviolet rays.
UV hard and wherein the to complete the curing of the mold coating layer
Provide a method of conversion . Furthermore, it is also possible to arrange a plurality of ultraviolet ray generating means in which a plurality of the fluorescent tubes are arranged in parallel in the web flow direction in the web flow direction to accelerate the curing of the ultraviolet effect type coating layer. As a fluorescent tube for generating ultraviolet light, a general mercury lamp such as a high-pressure mercury lamp, a metal halide lamp, a medium-pressure mercury lamp, or a low-pressure mercury lamp can be used, but a lamp with a low output is preferable. For example, a chemical lamp that selectively generates 352 nm ultraviolet light, a fluorescent lamp for trapping insects, a developing lamp for a copying machine, and the like can be used. The fluorescent tubes constituting the ultraviolet ray generating means are arranged as close to each other as possible, at equal intervals and in parallel. By arranging closely, the ultraviolet rays generated from the fluorescent tubes can interfere with each other and increase the intensity of the ultraviolet rays. Furthermore, by arranging them at equal intervals and in parallel, the entire surface of the ultraviolet-curable coating layer on the web can be uniformly irradiated with ultraviolet rays. When the curing of the ultraviolet curable coating layer is slow with only one unit in which the fluorescent tubes are arranged in parallel at equal intervals, it is easy to increase the curing speed by arranging a plurality of such units in the flow direction of the web. The interval at which the fluorescent tubes are arranged in parallel is from 0 mm to 1 mm.
00 mm is preferred. The width of the UV-curable coating layer coated on the web is preferably such that both ends are inside the fluorescent tubes arranged in parallel in the unit with at least one of both sides removed. It is preferable because the ultraviolet intensity on the surface of the mold coating layer becomes uniform. As the web transport means, a conventionally used belt conveyor, roll-to-roll transport device or the like may be selected according to the transport target. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 shows an embodiment of the ultraviolet irradiation apparatus of the present invention. Insect fluorescent lamp 1 with a main wavelength of 356 nm
Eight ultraviolet light generating means 4 arranged in parallel at intervals were set in succession so that the insect trapping fluorescent lamp 1 in the ultraviolet light generating means 4 was approximately 180 mm above the web and parallel to the flow direction. . Both sides are silicon-peeled to a thickness of 50 μm
m, a UV-curable pressure-sensitive adhesive composition prepared as follows on one side of a polyester film having a width of 200 mm.
g / m 2 with a roll coater so that the center line of the coating width is overlapped with the center line of the polyester film.
It was applied to a width of 20 mm. [Preparation method of UV-curable pressure-sensitive adhesive composition]
Acrylic rubber (Taclon PS220, Toa Paint Co.) was added to 100 g of a monomer mixture solution consisting of 90 g of 3,5,5 trimethylhexyl acrylate and 10 g of acrylic acid.
g in a stirrer container for 48 hours to dissolve,
A viscous solution of as was obtained. Further, nonylphenoxydipropylene glycol acrylate (M-11) was added to the solution.
7, Toa Gosei Chemical Industry Co., Ltd.) 10 g, neopentylglycol hydroxypivalate diacrylate having a molecular weight of 312 (KAYARAD MANDA Nippon Kayaku Co., Ltd.) was added to 0.1 g.
0005 mol (0.156 g) and acetophenone photoinitiator 2-hydroxy-2-methyl-1-phenylpropan-1-one (Darocur 1173, Merck)
After adding 02 g and stirring for about 30 minutes, an ultraviolet-curable pressure-sensitive adhesive composition was obtained. Next, about 60 g / m 2 of the above-mentioned UV-curable pressure-sensitive adhesive composition was applied to one surface of a polyester film having both surfaces subjected to silicon release treatment, and 50 μm of only one surface was subjected to silicon release treatment on the coating layer. A transparent polyester film having a width of 200 mm was peeled off, and the laminate was passed between rolls adjusted so that the thickness of the pressure-sensitive adhesive layer was 0.06 mm. So that the center two of the trapped fluorescent lamps are on the coating layer, transported at a rate of 1 meter per minute, and then continuously irradiated with ultraviolet light from a high-pressure mercury lamp with a main wavelength of 365 nm to adhere to both sides. Tape was manufactured. The light emitted from one fluorescent lamp for catching insects is so weak that the light intensity can be stared by the naked eye having a light intensity of about 0.5 mw / cm 2.
The intensity of the light was 2 or more, and as can be seen from the evaluation results below, it was found that the present ultraviolet irradiation apparatus was capable of performing ultraviolet polymerization in a short time and was a small and inexpensive ultraviolet irradiation apparatus. The properties of the obtained double-sided adhesive tape were evaluated as follows. [Adhesive Strength] As an adherend, a 2 mm thick, 30 mm wide, 120 mm long ground with a water-resistant abrasive paper of No. 280
mm stainless steel plate and a 0.025 mm-thick polyimide film (Kapton 100H, manufactured by DuPont) were used. A double-sided adhesive tape is 20 mm wide and 100 mm long.
mm, and peeled off the polyester film on one side, and temporarily attached to a stainless steel plate. Next, the other polyester film was peeled off, and the polyimide film was placed thereon and pressed at 80 ° C. at 5 kgf / cm 2 for 10 seconds. The adhesive test piece was placed in an air circulation oven adjusted to 153 ° C., and was subjected to 250 hours, 500 hours, and 750 hours.
Time, remove after 1000 hours, 18
The film was peeled off at a rate of 300 mm per minute in the 0 degree direction, and the adhesive strength was measured. As a result, the initial adhesive strength was 1.9 kg.
f / 2 cm, and after 250 hours, 500 hours, 75
The adhesive strength after 0 hour and after 1000 hours is 2.1k each.
gf / 2cm, 1.8kgf / 2cm, 1.8kgf /
At 2 cm and 1.8 kgf / 2 cm, there was no decrease in adhesive strength. [Heat-resistant holding power] The holding power was measured in accordance with the measuring method of the holding power in JIS Z 0237. As the adherend, 28
A 2 mm thick stainless steel plate polished with No. 0 water-resistant abrasive paper and a 0.05 mm thick aluminum foil were used. The bonding area was 25 × 25 mm for a stainless steel plate and 25 mm in width and 50 mm in length for an aluminum foil. The bonding method was performed in accordance with the preparation of the test piece for measuring the adhesive force. After bonding, a | weight of 1 kgf was applied vertically from the aluminum foil side, and the size of the displacement of the bonded portion after being left at 180 ° C. for 1 hour was measured. There is almost no displacement,
It was a double-sided pressure-sensitive adhesive tape with excellent heat retention. In the present embodiment, the coating layer of the ultraviolet-curable pressure-sensitive adhesive composition was cured only by an ultraviolet irradiation apparatus comprising a group of fluorescent lamps for trapping insects. In this case, the tack tends to be slightly lower. In this ultraviolet irradiation apparatus, if the method of polymerizing about 80% of the coating layer of the ultraviolet-curable pressure-sensitive adhesive composition and irradiating the ultraviolet rays of a high-pressure mercury lamp with a main wavelength of 365 nm to complete the polymerization, the tack increases and the polymerization increases. Time can be shortened and it is economical. [Effect] Since the surface of the ultraviolet-curable coating layer provided on the web can be uniformly irradiated with ultraviolet rays, there is no difference in the properties of the cured coating layer between the central portion in the width direction and both sides. A small and inexpensive ultraviolet irradiation device can be obtained, and the maintenance cost is also low. Since the fluorescent lamp for catching insects with low ultraviolet intensity is used, the influence on the human body is small. The number of units can be easily increased and decreased, and the line speed can be easily adjusted.
