RESIN COMPOSITION, CRACK INJECTION MATERIAL, AND CRACK REPAIR METHOD
PROBLEM TO BE SOLVED: To provide a resin composition suitable for a crack injection material of a structure capable of providing a cured product which is excellent in storage stability, has such viscosity as to be easily injected into cracks of a structure even at low temperature environment of -10°C or lower, can be cured for a short time, and has a good adhesion strength.SOLUTION: A resin composition contains a resin component composed of a radical reactive resin (A) and a radically polymerizable unsaturated monomer (B) having a (meth)acryloyloxy group in the molecule, aromatic tertiary amine (C) represented by a formula (I), and an organic peroxide (D). In the formula (I), Ris H, CHor OCH; and Rand Rare each independently C1-20 alkyl group or C1-20 hydroxyalkyl group.SELECTED DRAWING: None
【課題】貯蔵安定性に優れ、−１０℃以下の低温環境下でも構造物のひび割れなどに注入しやすい粘度であり、しかも短時間で硬化でき、良好な接着強度を有する硬化物が得られる構造物のひび割れ注入材の材料として好適な樹脂組成物の提供。【解決手段】ラジカル反応性樹脂（Ａ）と、分子中に（メタ）アクリロイルオキシ基を有するラジカル重合性不飽和単量体（Ｂ）とからなる樹脂成分と、式（Ｉ）で表される芳香族３級アミン（Ｃ）と、有機過酸化物（Ｄ）とを含有する樹脂組成物。（Ｒ１はＨ、ＣＨ３又はＯＣＨ３；Ｒ２及びＲ３は夫々独立にＣ１〜２０のアルキル基又はＣ１〜２０のヒドロキシアルキル基）【選択図】なし
