<p>PURPOSE: A fire-retardant and sound-absorbent coating composition is provided to prevent releasing of the coating material from the subject substrate with causing no shrinkage, crack and peeling off of the coating material even at extinguishing fire by comprising particular composition of respective constructional materials. CONSTITUTION: The composition comprises 25-60 wt.% of light aggregates, 20-60 wt.% of binder, less than 50 wt.% of heat-absorbent material, 5-30 wt.% of bulky agent and 2-20 wt.% of carbonating sound-absorbing fiber. The composition further is added with at least one of additives, for instance, less than 1.5 wt.% of surfactant, 5 wt.% or less of thickener, less than 2 wt.% of reinforcing agent, 2 wt.% or less of delaying agent and/or less than 1 wt.% of anti-bacterial agent. The coating composition is applied to surface of structural frame of buildings and/or constructional subjects to improve hardness and internal intensity, and/or sound-insulation effects of them.</p> |
