PRIMER COMPOSITION, WATERPROOF FLOOR SLAB STRUCTURE USING SAME, AND METHOD FOR WATERPROOFING FLOOR SLAB
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.
