INTUMESCENT FIRE-RESISTANT COATING COMPOSITION INCLUDING SILICA AEROGEL

摘要

Disclosed is a foamable fire resistant coating composition which improves heat insulation by forming an additional foamed heat insulation layer on an existing silicate which is foamed and expanded by heat in a high temperature environment such as a fire by adding super heat insulating silica aerogel powder to foamable fire resistant coating including silicates. The foamable fire resistant coating composition according to one embodiment of the present invention includes 80-97 wt% of silicates, 1-10 wt% of aerogel, 1-5 wt% of functional fillers, and 1-5 wt% of additives. [Reference numerals] (AA) Time(minute); (BB) Temperature(°C); (CC) (Note)The surface temperature of the opposite surface exposed to fire was measured; (DD) Coat is the prepared specimen by coating a film composition containing 3 wt% of aerogel manufactured by an embodiment at 2 mm
