摘要
A water-based expandable fireproof coating for steel structure. The fireproof coating consists of the components in mass percentage: 20-45% of coating matrix, 25-45% of nano-flame retardant, 0.1-10% of flame-retardant synergist, 1-10% of filler, 0.2-5% of auxiliary agent and 10-30% of water. The preparation method of the fireproof coating comprises the steps: firstly preparing the nano-flame retardant; secondly adding a water-based epoxy emulsion, a water-based epoxy curing agent and a self-crosslinking silicone acrylic emulsion in the coating matrix into a stirring barrel, and stirring uniformly; adding the nano-flame retardant, the flame-retardant synergist, the filler, the auxiliary agent and water, and stirring, then grinding and filtering the mixture. The fireproof coating has a high expansion rate, and has the fire endurance up to 120 minutes as well as the coating thickness of 2 mm.
