Description
引張せん断接着強さ:JIS K 6850に従い測定した。具体的には被着材として、耐熱パイレックス(登録商標)ガラス(25mm×25mm×2.0mm)を用いて、接着部位を直径8mmとして、作成した樹脂組成物にて、2枚の耐熱パイレックス(登録商標)ガラスを貼り合わせ、無電極放電ランプを使用したフュージョン社製硬化装置により、365nmの波長の積算光量2000mJ/cm2の条件にて硬化させ、引張せん断接着強さ試験片を作成した。作成した試験片は、万能試験機を使用して、温度23℃、湿度50%の環境下、引張速度10mm/minで引張せん断接着強さを測定した。
剥離試験:上記耐熱パイレックス(登録商標)ガラスに樹脂組成物を塗布し、無電極放電ランプを使用したフュージョン社製硬化装置により、365nmの波長の積算光量2000mJ/cm2の条件にて樹脂組成物を硬化させ、剥離試験体を作成した。得られた試験体を、温水(80℃)に浸漬し、耐熱パイレックス(登録商標)ガラスから剥離する時間を測定し、また剥離状態も観察した。
原材料を表1、表2、表3に示す組成で使用したこと以外は実施例1と同様にして樹脂組成物を作成した。得られた樹脂組成物に関して、実施例1と同様に引張せん断接着強さの測定及び剥離試験を行った。それらの結果を表1、表2、表3に示す。
R−684:ジシクロテンタニルジアクリレート(日本化薬社製)
M−101A:フェノールエチレンオキサイド2モル変成アクリレート(東亜合成社製)
TPO:2,4,6−トリメチルベンゾイルジフェニルホスフィンオキサイド(BASF社製ルシリンTPO)
QM:ジシクロペンテニルオキシエチルメタクリレート(ローム&ハース社製QM−657)
BZ:ベンジルメタクリレート(共栄社化学社製ライトエステルBZ)
IBX:イソボルニルメタクリレート(共栄社化学社製ライトエステルIB−X)
原材料を表4に示す組成で使用したこと以外は実施例1と同様にして樹脂組成物を作成した。得られた樹脂組成物に関して、実施例1と同様に引張せん断接着強さの測定及び剥離試験を行った。それらの結果を表4に示す。
2−HEMA:2−ヒドロキシエチルメタクリレート
MTEGMA:メトシキテトラエチレングリコールモノメタクリレート(新中村化学社製NKエステルM−90G)
実施例1、実施例6及び比較例6の樹脂組成物をそれぞれ用いて、無電極放電ランプを使用したフュージョン社製硬化装置により、365nmの波長の積算光量を500、1000、2000、4000mJ/cm2と変えて接着剤組成物を硬化させ、剥離試験体、引張せん断接着強さ試験片を作成したこと以外は、実施例1と同様に引張せん断接着強さの測定及び剥離試験を行った。それらの結果を表5に示す。
実施例1及び6の樹脂組成物を使用し、実施例1と同様に剥離試験体を作成し、温水の温度40℃、50℃、60、70℃を変えて剥離試験を行った。その結果を表5に示す。その結果、いずれの温度でも剥離性を有する。
