Eco-friendly functional finish composition using graphene and surface protection and strengthening finishing method of concrete and steel structure using the same
The present invention relates to an eco-friendly functional finishing composition using graphene, and a surface protection/strengthening finishing method for concrete and steel structures using the same. According to the present invention, the functional finishing composition comprises 1-60 wt% of a modified filler and 40-99 wt% of a function improvement binder. The function improvement binder comprises 30-98 wt% of a methyl methacrylate-butyl acrylate-styrene copolymer, 1-20 wt% of polyester polyol, 0.1-20 wt% of a bisphenol A-epichlorohydrin polymer, 0.1-15 wt% of polychlorotrifluoroethylene, 0.1-15 wt% of methylene bis stearic acid amide, and 0.01-15 wt% of a graphene dispersion with respect to the weight thereof. According to the present invention, the functional finishing composition provides excellent workability, electrical conductivity, thermal conductivity, deodorization, contamination resistance, chemical resistance, non-flammability, UV resistance, chloride ion penetration resistance, neutralization resistance, freeze-thaw resistance, and durability, thereby realizing extension of a performance period, reduction of maintenance costs, and enhancement of workability of a concrete structure.
