CURABLE RESIN COMPOSITION, CONCRETE COATING COMPOSITION, LINKING MATERIAL, TUBULAR LINING MATERIAL AND CIVIL ENGINEERING OR CONSTRUCTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To obtain a curable resin composition that comprises a non-styrene type vinyl ester resin having properties of cast plate and laminate at the same levels as those of a styrene type vinyl ester resin, adhesion strength keeping an initial value even after long-term immersion in warm water and a weight change ratio after immersion in warm water similar to that of a cured styrene type vinyl ester resin, is coated on concrete and has excellent curability and surface drying properties. SOLUTION: The curable resin composition comprises (A) 30-60% by mass of an epoxy (meth)acrylate composed of a reaction product of an aromatic epoxy resin and (meth)acrylic acid, (B) 10-30% by mass of ethoxylated bisphenol A dimethacrylate having 2-20 addition molar number of ethylene oxide and (C) 20-40% by mass of a monofunctional (meth)acrylate-based monomer having a group containing a cyclic hydrocarbon group having one carbon-carbon double bond or nitrogen atom as an alcohol residue in a ring. The concrete coating composition, the tubular lining material and the civil engineering or construction structure are obtained by using the curable resin composition. COPYRIGHT: (C)2006,JPO&NCIPI
