A COMPOSITE OF FIRE-RESISTANCE COATING MATERIALS COMPRISING NEW HEAT-RESISTANCE MATERIALS

摘要

The present invention relates to a fireproof coating material composition which comprises with respect to the total weight of the composition: (a) 20-40 wt% of cement; (b) 15-40 wt% of blast furnace slag; (c) 5-20 wt% of at least one species selected from mica and alumina; (d) 0-10 wt% of fly ash in a fluidized bed boiler; (e) 10-40 wt% of expanded vermiculite; (f) 10-30 wt% of at least one species selected from calcium carbonate and limestone; and (g) 0.5-20 wt% of a material for increasing viscosity. The fireproof coating material composition is capable of forming an appropriate density by securing porosity at a certain level, reducing crack generation with non-shrinkage properties with respect to shrinkage, particularly, and significantly improving resistance with respect to heat during a fire.
