TWO COMPONENT-TYPE FINISHING MATERIAL COMPOSITIOM FOR CONCRETE SLAB CONTAINING SURFACE MODIFIED ULTRAMICRO SILICA AND NANO BOHEMITE, AND PRODUCING METHOD THEREOF

摘要

Disclosed is a two component-type finishing material composition which includes: a main material including 50-70 wt% of an epoxy resin, 1-5 wt% of mineral split, 1-10 wt% of a diluent, 0.01-3 wt% of a defoaming agent, 1-6 wt% of a leveling agent, 0.1-4 wt% of a wetting agent, and 3-22 wt% of microsilica with surface modified by a silane coupling agent; and a curing agent including 40-60 wt% of modified aliphatic amine, 20-30 wt% of modified aromatic amine, 1-8 wt% of promoters, 0.01-3 wt% of a defoaming agent, and 3-20 wt% of bohemite nanoparticles with surface modified by a silane coupling agent.
