In this study, titanium dioxide/silicone sol was applied to the cypress wood which is the building interior material to reduce the damage caused by the smoke in the fire and smoke density was investigated in flaming mode using smoke density chamber. The titanium dioxide/silicone sol was measured for smoke density according to the ASTM E 662 test method based on performance standard of flame retardancy. The maximum smoke density of wood coated with flame retardants increased in the order of TiO2(A)TSS＜TiO2(A)SS＜TiO2(R)SS＜TiO2(R)TSS, which was less than 400, which is the fire safety standard for wood. The smoke density at the beginning of the fire (VOF4) increased in the order of TiO2(A)SS＜TiO2(R)TSS＜TiO2(A)TSS＜TiO2(R)SS, and TiO2(R)SS was the most dangerous materials due to the highest smoke density at the beginning of the fire. |
