Abstract
In this paper, effects of Pt compounds (C8H18OPtSi2) on pyrolysis and oxidation characteristics of silicone foam (SiFs), gas volatiles of SiFs during pyrolysis and oxidation process, influence of heating rate on pyrolysis and oxidation of SiFs, and the thermal reaction kinetics of SiFs were analysed. The residual mass of SiFs at 900.0 °C in N2 atmosphere increased from 59.7 to 74.1% as the content of Pt compounds changed from 0.3 to 1.2 mass%. Whereas, the residual mass of SiFs in air atmosphere was higher than in N2 atmosphere. CO2 and CO as new gas volatiles appeared in air atmosphere when compared in N2 atmosphere. The residual mass of SiFs rose with the increase of heating rate. Besides, the apparent activation energy in N2 atmosphere grew significantly with conversion rate, and the apparent activation energy in air atmosphere was significantly lower than that in N2 atmosphere.
