The present invention provides a primer composition which is used for applying a radical-curable resin-based waterproof material for a floor slab onto a concrete floor slab of an existing or newly established road bridge such as a highway bridge. The primer composition is suitable for use in applying a radical-curable resin-based waterproof material for a floor slab, for which a problem of troublesome application thereof, for example, a problem in that a large machine is required for application thereof, is solved. The primer composition is a resin composition containing a urethane (meth)acrylate resin, (B) a polymerizable unsaturated monomer containing a hydroxyalkyl (meth)acrylate (B-1) and another polymerizable unsaturated monomer (B-2), (C) a curing accelerator, (D) a paraffin wax, and (E) a drying aid, in which the above components satisfy a specific molar ratio and specific mass ratios. The primer composition has a good crack-load-following capability, blistering resistance, adhesiveness, and bending resistance. The present invention also provides a waterproof floor slab structure using the primer composition and a method for waterproofing a floor slab.
本发明提供了一种底涂组合物,用于在现有或新建公路桥梁(如高速公路桥梁)的混凝土楼板上涂抹楼板用激化固化型树脂基防水材料。该底涂组合物适用于涂抹楼板用激化固化型树脂基防水材料,从而解决了涂抹麻烦的问题,例如,需要大型机器才能涂抹的问题。该底漆组合物是一种树脂组合物,含有聚氨酯(甲基)丙烯酸酯树脂、(B) 一种含有羟基烷基(甲基)丙烯酸酯(B-1)和另一种可聚合不饱和单体(B-2)的可聚合不饱和单体、(C) 一种固化促进剂、(D) 石蜡和 (E) 一种干燥助剂,其中上述组分满足特定的摩尔比和特定的质量比。该底漆组合物具有良好的抗开裂能力、抗起泡性、粘合性和抗弯性。本发明还提供了一种使用该底漆组合物的防水楼板结构和一种楼板防水方法。
