Fire Performances, Hot Properties and Decomposition Kinetics of Sb₂O₃/DBDPE/RTV

Abstract:

Fire and hot properties of title composite were taken by the method of vertical burning, OI, and TG. Fire performance experiments demonstrated that the scale of flame retardant property of Sb2O3/ DBDPE/RTV was FV-0, OI was 46. Hot decomposition temperature is about 400 oC to 520 oC with the amount of 20wt% as additives. The kinetic parameters of the decomposition reaction of the title composite have been studied by means of DSC. The data are fitted to the integral, differential and exothermic rate equations by linear least-squares, iterative, combined dichotomous and least-squares methods, respectively. The study leads the reader to the conclusion that the empirical kinetic model functions in differential form, the values of and of this reaction were , -1857.20 kJ/mol and 244.9 s-1 respectively. Sb2O3/ DBDPE are a kind of flame retardant which own its flame retardant function to higher activation energy but the release of halogen. It is a usable retardant during the lifetime.
