本發明之實施例雖參照附圖而記述，但該等附圖只供理解附圖之用，而非限定本發明者。The embodiments of the present invention are described with reference to the drawings, but the drawings are only for understanding the drawings, and are not intended to limit the invention.
以下，針對用以實施本發明之形態，一面參照附圖詳細說明。Hereinafter, the form for carrying out the invention will be described in detail with reference to the accompanying drawings.
圖1、圖2係用以說明本發明之一實施形態之金屬鹵素燈之圖，圖1係基本結構，圖2係將其一部份放大顯示之構成圖。1 and 2 are views for explaining a metal halide lamp according to an embodiment of the present invention, and Fig. 1 is a basic structure, and Fig. 2 is a block diagram showing a part thereof enlarged.
圖1、圖2中，符號11係具有紫外線透射性之石英玻璃製且形成有放電空間10之徑φ為27.7 mm、壁厚m為1.5 mm、發光長度L為1800 mm左右之一層發光管。於該發光管11之長度方向兩端之內部，分別配置有一對耐火性金屬製放電電極、即例如以鎢材形成之電極121、122，電極121、122彼此隔開。電極121、122分別經由內部引線131、132，而熔接於例如鉬之金屬箔141、142之一端。於金屬箔141、142之另一端，熔接有未圖示之外部引線之一端。金屬箔141、142之部份係將內部引線131、132與外部引線間之發光管11加熱並密封者。In Fig. 1 and Fig. 2, reference numeral 11 is a one-layer arc tube made of quartz glass having ultraviolet transmittance and having a diameter φ of a discharge space 10 of 27.7 mm, a wall thickness m of 1.5 mm, and an emission length L of about 1800 mm. A pair of refractory metal discharge electrodes, that is, electrodes 121 and 122 made of, for example, a tungsten material are disposed inside the both ends of the arc tube 11 in the longitudinal direction, and the electrodes 121 and 122 are spaced apart from each other. The electrodes 121 and 122 are respectively welded to one ends of the metal foils 141 and 142 of molybdenum via the inner leads 131 and 132, respectively. At the other end of the metal foils 141 and 142, one end of an external lead (not shown) is welded. Portions of the metal foils 141, 142 are obtained by heating and sealing the arc tubes 11 between the inner leads 131, 132 and the outer leads.
又，金屬箔141、142可為接近形成發光管11之石英玻璃之熱膨脹率之任意材料，在此使用鉬作為適於該條件者。Further, the metal foils 141, 142 may be any material close to the thermal expansion coefficient of the quartz glass forming the arc tube 11, and molybdenum is used here as suitable for the condition.
於一端分別連接於金屬箔141、142之外部引線之另一端，電性連接有例如被絕緣密封在陶瓷製插座151、152內之供電用引線161、162，進而引線161、162與未圖示之電源電路連接。The other ends of the outer leads of the metal foils 141 and 142 are respectively connected to one end, and the power supply leads 161 and 162 which are insulated and sealed in the ceramic sockets 151 and 152 are electrically connected, for example, and the leads 161 and 162 are not shown. The power circuit is connected.
於發光管11內，以1.3[kPa]之壓力封入維持電弧放電之充分量之稀有氣體之氬氣，與用以使紫外線發光之水銀(Hg)，此外還封入鐵(Fe)、鉈(Tl)、錫(Sn)、進而碘化汞(HgI2 )。鐵、鉈、錫分別係發光金屬。除該等發光金屬外，亦可含增強之發光波長區域不在320 nm~380 nm內之發光金屬。另，發光金屬除金屬單體之狀態外，亦可以金屬鹵化物之狀態封入。In the arc tube 11, a argon gas of a rare gas for maintaining a sufficient amount of arc discharge is maintained at a pressure of 1.3 [kPa], and mercury (Hg) for emitting ultraviolet rays is further sealed with iron (Fe) and strontium (Tl). ), tin (Sn), and further mercury iodide (HgI 2 ). Iron, bismuth and tin are respectively luminescent metals. In addition to the luminescent metals, the luminescent metal having an enhanced illuminating wavelength region not in the range of 320 nm to 380 nm may be included. Further, in addition to the state of the metal monomer, the luminescent metal may be enclosed in the state of a metal halide.
利用該金屬鹵素燈所放射之紫外線，可促進含有特定光引發劑之紫外線硬化性樹脂組成物之硬化。如此之樹脂組成物係藉由對光引發劑照射紫外線，而引發樹脂組成物中含有之聚合性樹脂之聚合，使該樹脂組成物藉由該聚合而硬化。The ultraviolet rays emitted from the metal halide lamp can promote the hardening of the ultraviolet curable resin composition containing a specific photoinitiator. In such a resin composition, polymerization of a polymerizable resin contained in the resin composition is initiated by irradiating ultraviolet rays to the photoinitiator, and the resin composition is cured by the polymerization.
此處，參照圖3，針對圖1所示之金屬鹵素燈與先前者之比較進行說明。圖3係將圖1所示之金屬鹵素燈(封入鐵、鉈、錫)所放射之紫外線發光光譜，與先前之金屬鹵素燈(封入鐵：以下稱鐵金屬鹵素燈)所放射之紫外線發光光譜進行比較而顯示之圖。為分別以燈輸入21600 W之恒功率而點燈之情形。Here, a comparison of the metal halide lamp shown in Fig. 1 with the former will be described with reference to Fig. 3 . Fig. 3 is an ultraviolet luminescence spectrum emitted by the metal halide lamp (sealed in iron, bismuth, tin) shown in Fig. 1 and the ultraviolet luminescence spectrum of the previous metal halide lamp (sealed iron: hereinafter referred to as iron metal halide lamp). Compare and display the graph. In the case of inputting a constant power of 21600 W with a lamp, respectively.
由圖3可知，圖1所示之金屬鹵素燈相較於鐵金屬鹵素燈，可使320~380 nm之波長區域之累積光量提高。As can be seen from FIG. 3, the metal halide lamp shown in FIG. 1 can increase the cumulative light amount in the wavelength region of 320 to 380 nm compared to the iron metal halide lamp.
此處，參照圖4，針對適宜作為本實施形態之來自金屬鹵素燈之紫外線的被照射物且在波長320~380 nm間具有吸收波長之光引發劑進行說明。該光引發劑係應含於紫外線硬化性樹脂組成物中者。Here, a photoinitiator which is suitable as an object to be irradiated with ultraviolet rays from a metal halide lamp of the present embodiment and has an absorption wavelength between 320 nm and 380 nm will be described with reference to Fig. 4 . The photoinitiator should be contained in the ultraviolet curable resin composition.
圖4係顯示光引發劑4-(二甲胺基)二苯甲酮(4-(Dimethylamino) benzophenone)之光吸收率之波長相依性。如圖示該光引發劑具有320~380 nm之吸收波長，其吸收率在350 nm附近成為峰值。又，圖4中實線表示將該光引發劑之濃度設為0.0009%之時，虛線相同地表示將其設為0.0043%之時(相互縱軸係相對值)。現實上，雖將濃度設為0.0009%左右而使用，但即使如0.0043%之高濃度，吸收波長區域亦不會產生變化。Figure 4 is a graph showing the wavelength dependence of the light absorptivity of the photoinitiator 4-(Dimethylamino)benzophenone. As shown, the photoinitiator has an absorption wavelength of 320 to 380 nm, and its absorption rate peaks around 350 nm. In addition, the solid line in FIG. 4 indicates that the concentration of the photoinitiator is 0.0009%, and the broken line similarly indicates that it is 0.0043% (relative vertical axis relative value). Actually, although the concentration is set to about 0.0009%, even if the concentration is as high as 0.0043%, the absorption wavelength region does not change.
思及將自圖1所示之金屬鹵素燈之波長區域320~380 nm之紫外線，照射於含有圖4所示之具有吸收波長區域320~380 nm之特性之光引發劑之紫外線硬化性樹脂組成物，使其硬化之情形。一般言之，被吸收之光量越多越能使樹脂硬化，因此與鐵金屬鹵素燈相比使用特定之紫外線強度高之金屬鹵素燈以上述方式使樹脂硬化時，將更提高樹脂組成物之硬化速度。It is considered that ultraviolet rays of 320 to 380 nm in the wavelength region of the metal halide lamp shown in FIG. 1 are irradiated onto the ultraviolet curable resin containing the photoinitiator having the characteristics of 320 to 380 nm in the absorption wavelength region shown in FIG. The thing that makes it harden. In general, the more the amount of light absorbed, the harder the resin is. Therefore, when a metal halogen lamp having a specific ultraviolet intensity is used to harden the resin in the above manner as compared with the iron metal halide lamp, the hardening of the resin composition is further enhanced. speed.
又，作為本實施形態之來自金屬鹵素燈之紫外線之被照物，4-(二甲胺基)二苯甲酮係其中一例，不限於此。即，本實施形態之金屬鹵素燈係可使320~380 nm之波長區域之累積光量與鐵金屬鹵素燈相比提高者，只要是具有320~380 nm吸收波長區域之光引發劑，即適於作為被照射物。Further, as an object of ultraviolet light from a metal halide lamp of the present embodiment, 4-(dimethylamino)benzophenone is not limited thereto. In other words, the metal halide lamp of the present embodiment can increase the cumulative amount of light in the wavelength region of 320 to 380 nm as compared with the iron metal halide lamp, and is suitable as long as it is a photoinitiator having an absorption wavelength region of 320 to 380 nm. As an object to be irradiated.
下式係將發光源之發光光譜曲線設為α(λ)、將光引發劑之吸收光譜曲線設為φ(λ)時之利用光之光引發劑之反應程度之式。The following formula is a formula in which the luminescence spectrum curve of the luminescence source is α (λ) and the absorption spectrum curve of the photoinitiator is φ (λ), and the degree of reaction of the photoinitiator using the light is used.
上式中，使用圖3所示之α(λ)(本實施形態及鐵金屬鹵素(先前)之各者)與圖4所示之φ(λ)，計算設x為320、y為380時之情形，求得利用本實施形態之金屬鹵素燈之情形與利用鐵金屬鹵素燈之情形之樹脂硬化之比，此為如圖5所示之結果。即，若使用本實施形態之金屬鹵素燈，可使以4-(二甲胺基)二苯甲酮為光引發劑之紫外線硬化性樹脂組成物之硬化速度，比使用鐵金屬鹵素燈之情形更為提高。再者，x、y分別係波長(nm)。In the above formula, α(λ) (the present embodiment and each of the iron metal halides (previous)) shown in Fig. 3 and φ(λ) shown in Fig. 4 are used, and it is calculated that x is 320 and y is 380. In the case of the case where the metal halide lamp of the present embodiment is used and the ratio of the resin hardening in the case of using the iron metal halide lamp, the result shown in Fig. 5 is obtained. In other words, when the metal halide lamp of the present embodiment is used, the curing rate of the ultraviolet curable resin composition using 4-(dimethylamino)benzophenone as a photoinitiator can be made higher than that in the case of using an iron metal halide lamp. More improved. Further, x and y are wavelengths (nm), respectively.
如此，為使320~380 nm之光量變多，使用封入有鐵、鉈、錫之金屬鹵素燈，對含有吸收波長區域320~380 nm之光引發劑之樹脂組成物照射紫外線，從而可謀求其硬化速度之提高。In order to increase the amount of light in the range of 320 to 380 nm, a metal halide lamp in which iron, antimony or tin is sealed is used, and a resin composition containing a photoinitiator having an absorption wavelength region of 320 to 380 nm is irradiated with ultraviolet rays, thereby making it possible to obtain ultraviolet light. Increased hardening speed.
