AQUEOUS RESIN COMPOSITION FOR FORMING THICK FILM, MANUFACTURING METHOD THEREFOR, SURFACE TREATMENT METHOD, AND CONCRETE STRUCTURE

摘要

The present invention is an aqueous resin composition for forming thick films, the composition comprising an aqueous synthetic resin emulsion (A) and a filler (B) and the non-volatile components being 65-80 mass%. The aqueous resin composition for forming thick films is characterized in that the percentage of the observed specific gravity with respect to the theoretical specific gravity is 97% or more. Using said aqueous resin composition for forming thick films: drying within twelve hours after thick film formation and coating is possible; odors are not generated during work; and it is possible to form a coating with excellent water resistance, acid resistance and alkali resistance. In particular, it is possible to form a coating that conforms to the quality standards of standard types C and D provided in the Sewer Concrete Structure Corrosion-Limiting Technology and Corrosion-Proofing Technology Manual (April 2012).
