PURPOSE:To improve the fire-resistant performance by blending a prescribed binder with an unburned vermiculite, inorganic fiber and one or more of a hydrogencarbonic acid compound, a carbonate compound and a hydroxylated compound. CONSTITUTION:The objective refractory coating material is produced by using and blending 100 pts.wt. hydraulic cement such as silica cement and/or 5-200 pts.wt. water glass, providing a binder, then blending 100 pts.wt. resultant binder with 5-700 pts.wt. unburned vermiculite and 1-300 pts.wt. inorganic fiber such as alkali-resistant glass fiber, affording a blend then blending one or more of a hydrogencarbonic acid compound decomposing at a temperature within 700 deg.C and a carbonate compound decomposing at a temperature within 800 deg.C, providing a composition of active components, subsequently blending the obtained blend with the composition of the active components in an amount of 15-1800 pts.wt. based on 100 pts.wt. binder in the blend, 1-200 pts.wt. reemulsified synthetic resin powder based on 100 pts.wt. binder in the blend and 5-400 pts.wt. inorganic lightweight aggregate based on 100 pts.wt. binder in the blend. |
