surface finishing materials of concrete floor including lamellar micro silica and silane coupling agent

摘要

PURPOSE: 2 liquid type concrete floor surface finishing material is provided to have an excellent adhesive force in a wetted surface, a self smoothness and a surface hardness by adding a plate shaped micro silica and a silane coupling agent to an epoxy resin-based main material. CONSTITUTION: 2 liquid type concrete floor surface finishing material comprises a first material and a second material. The first material comprises an epoxy resin, a silane coupling agent, and a plate shaped micro silica. The second material comprises an amine-based curing agent and a silane coupling agent. The first material comprises 50-70 weight% of epoxy resin, 5-22 weight% of silane coupling agent, 1-5 weight% of mineral spirit, 1-15 weight% of plate shaped micro silica, 1-10 weight% of diluent, 0.01-3 weight% of mineral antifoaming agent, 1-5 weight% of leveling agent, and 0.1-3 weight% of wetting agent. The second material comprises 40-60 weight% of denaturation aliphatic amine, 20-30 weight% of denaturation aromatic amine, 10-20 weight% of silane coupling agent, 1-8 weight% of accelerant, 0.1-5 weight% of silicon-based antifoaming agent. The first material and the second material are mixed as the weight ratio of 3:1.
