RADICAL POLYMERIZABLE RESIN COMPOSITION AND STRUCTURE REPAIRING MATERIAL
Provided are a radical polymerizable resin composition and a structure repairing material that, when being used for repairing a concrete structure, allow a repair work to be executed even in a low-temperature environment, are capable of achieving high strength and a low rate of shrinkage caused by curing, and are capable of suppressing cracks. This radical polymerizable resin composition contains: a radical polymerizable resin (A) that includes at least one selected from the group consisting of vinyl ester resins, urethane (meth)acrylate resins, and polyester (meth)acrylate resins; a radical polymerizable monomer (B) that includes an unsaturated compound (B1) having an isobornyl group; and an hydroxyl group-containing aromatic tertiary amine (C) represented by general formula (I), wherein the total contained amount of the radical polymerizable resin (A) and the radical polymerizable monomer (B) is 75 mass% or more. This structure repairing material contains the radical polymerizable resin composition, an organic peroxide, and a filling material (Z).
提供在用于混凝土结构物的修补的情况下，即使在低温环境下也能够施工，高强度，由固化引起的收缩率低，并且可以抑制裂缝的自由基聚合性树脂组合物以及结构物修补材料。一种自由基聚合性树脂组合物以及含有该自由基聚合性树脂组合物、有机过氧化物、和填充材料(Z)的结构物修补材料，上述自由基聚合性树脂组合物含有自由基聚合性树脂(A)、自由基聚合性单体(B)、以及通式(I)所示的含有羟基的芳香族叔胺(C)，上述自由基聚合性树脂(A)包含选自乙烯基酯树脂、氨基甲酸酯(甲基)丙烯酸酯树脂、和聚酯(甲基)丙烯酸酯树脂中的至少1种，上述自由基聚合性单体(B)包含具有异冰片基的不饱和化合物(B1)；上述自由基聚合性树脂组合物含有合计75质量％以上的自由基聚合性树脂(A)和自由基聚合性单体(B)。
