この発明は、電気機器等のケースを密封する場合に用い
る紫外線硬化樹脂組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an ultraviolet curable resin composition used for sealing cases of electrical equipment and the like.
紫外線硬化樹脂は空隙充填率がよく、また揮発分が少な
く、しかも硬化収縮が殆どないため、密封系の電気機器
（リレー、スイッチ、タイマ）等のシール剤として使用
されている。Ultraviolet curable resins have a good void filling rate, low volatile content, and almost no shrinkage upon curing, so they are used as sealants for sealed electrical equipment (relays, switches, timers), and the like.
しかしながら、第１図および第２図に示すように、ケー
ス１の孔２をシールするために紫外線硬化樹脂３を使用
した場合、第３図に拡大して示すように紫外線反射剤３
のうちケース１の内部に入り込んだ部分Ａでは紫外線が
届かないため、その部分だけが未硬化のまま残る場合が
あった。リレー、スイッチ、タイマ等の電気機器は内部
に精密接点をもっているため、紫外線硬化樹脂の未硬化
物が長期の使用中に連発して接点に付着し、接触障害を
ひき起こすおそれがあった。However, as shown in FIGS. 1 and 2, when the ultraviolet curing resin 3 is used to seal the hole 2 of the case 1, the ultraviolet reflector 3 is
Since the ultraviolet rays do not reach the portion A that has entered the inside of the case 1, only that portion may remain uncured. Electrical devices such as relays, switches, and timers have internal precision points, so there is a risk that uncured UV-cured resin may repeatedly adhere to the contacts during long-term use, causing contact failure.
そのため、熱硬化併用型の樹脂も使用されるが、内部の
ガスが加熱によって膨張し、ピンホールが生じやすかっ
た。また、ケース内の電気機器によっては熱をかけられ
ないものもある。さらに、熱を加えるための工程が必要
となり、密閉時の工程が複雑になるという問題があった
。For this reason, thermosetting resins are also used, but the gas inside expands when heated, which tends to cause pinholes. Also, some electrical devices inside the case cannot be heated. Furthermore, a process for applying heat is required, complicating the sealing process.
この発明の目的は、光が届かない部分にも光を入射させ
ることができ、未硬化部分ができるのを防止した紫外線
硬化樹脂組成物を提供することである。An object of the present invention is to provide an ultraviolet curable resin composition that allows light to enter areas where light cannot reach and prevents the formation of uncured areas.
（発明の開示）
この発明の紫外線硬化樹脂組成物は、紫外線硬化樹脂に
紫外線反射剤を配合したことを特徴とするものである。(Disclosure of the Invention) The ultraviolet curable resin composition of the present invention is characterized in that an ultraviolet curable resin is blended with an ultraviolet reflector.
このため、この発明によれば、紫外線硬化樹脂に配合さ
れた紫外線反射剤によって光が反射拡散されるため、光
が直接入射されない部分も充分に硬化させることができ
る。Therefore, according to the present invention, since light is reflected and diffused by the ultraviolet reflector blended into the ultraviolet curable resin, it is possible to sufficiently cure even areas where light is not directly incident.
前記紫外線反射剤としては、たとえばＴｉ（ｈ、 Ａｌ
ｌ０゜ＭｇＯ，Ｍｌ、 ＡＲ，ＡＩ等の粉末があげられ
、これらの１種または２種以上を紫外線硬化樹脂に配合
する。Examples of the ultraviolet reflector include Ti(h, Al
Examples include powders such as 10°MgO, Ml, AR, and AI, and one or more of these may be blended into the ultraviolet curing resin.
紫外線反射剤の配合量は紫外線硬化樹脂に対して５〜６
０容量％、なかんづく２０〜６０８１％であるのが適当
であり、紫外線反射剤の配合量が前記範囲より大なると
きは光が紫外線硬化樹脂の表面近くで反射されてしまい
中まで入射されなくなる。一方、紫外線反射剤の配合量
が前記範囲より小なるときは紫外線反射剤を配合した意
義がなく未硬化部分の発生を防止できなくなる。The amount of ultraviolet reflector added is 5 to 6 to the amount of ultraviolet curing resin.
It is appropriate that the amount is 0% by volume, especially 20 to 6081%; if the amount of the ultraviolet reflector exceeds the above range, the light will be reflected near the surface of the ultraviolet curable resin and will not enter the inside. On the other hand, if the amount of the ultraviolet reflector is less than the above range, there is no point in adding the ultraviolet reflector and the generation of uncured portions cannot be prevented.
かかる紫外線反射剤を配合する紫外線硬化樹脂はその種
類がとくに限定されるものではない。The type of ultraviolet curing resin containing such an ultraviolet reflector is not particularly limited.
つぎに実施例をあげてこの発明の紫外線硬化樹脂組成物
を詳細に説明する。Next, the ultraviolet curable resin composition of the present invention will be explained in detail with reference to Examples.
実施例： 紫外線硬化樹脂として、エポキシアクリレー

して３０容量％配合した。Example: As an ultraviolet curable resin, 3 parts by weight of benzoin isopropyl ether as a photopolymerization initiator was blended with 100 parts by weight of epoxy acrylate resin, and Tl01. ^ItO
, MgO+Ni+Ag powders were mixed in an amount of 30% by volume with respect to the resin.
一方、第１図および第２図に示すようなポリエチレンテ
レフタレートのケースに直径１龍の孔をあけ、この孔を
前記紫外線反射剤を配合した紫外線硬化樹脂でシールし
、これに高圧水銀灯を３０秒間照射して硬化させた。On the other hand, a hole with a diameter of 1 inch was made in a polyethylene terephthalate case as shown in Figs. It was irradiated and cured.
また、比較例として、紫外線反射剤を配合しないもの（
比較例１）と、Ｓｉｎ、を３０容量％配合したものにつ
いても同様にして硬化させた。In addition, as a comparative example, a product that does not contain an ultraviolet reflector (
Comparative Example 1) and a mixture containing 30% by volume of Sin were also cured in the same manner.
つぎに、未反応物を定量するために、ケースを破壊し、
クロロホルムでケース内面に存在する未反応物を抽出し
、抽出物をガスクロマトグラフで測定した。その結果を
下表に示した０表から明らかなように、実施例はいずれ
も比較例に比して未反応物が少なかった。したがって、
充填剤として紫外線反射剤を含む紫外線硬化樹脂は光が
直接照射さない部分も硬化させることがわかる。Next, in order to quantify unreacted substances, the case was destroyed and
Unreacted substances present on the inner surface of the case were extracted with chloroform, and the extract was measured using a gas chromatograph. As is clear from Table 0 showing the results, all of the Examples had less unreacted substances than the Comparative Examples. therefore,
It can be seen that the ultraviolet curable resin containing an ultraviolet reflector as a filler cures areas that are not directly irradiated with light.
