阻燃HIPS塑料热解动力学模型
Pyrolysis kinetics modeling of flame retarded HIPS
摘要
Abstract
A thermo-gravimetric (TG) study of flame retarded high impact polystyrene( (Br-Sb-HIPS) pyrolysis was conducted at various heating rates(5 ℃·min-1 ,10 ℃·min-1 , 15 ℃·min-1). A kinetic model of the pyrolysis of flame retarded HIPS that contains three series reaction was built. The activation energy of pyrolysis reaction of flame retarded HIPS obtained by the method of Flynn-Wall-Ozawa changed between 103-307 kJ·mol-1. Parameters were solved by a multidimensional unconstrained nonlinear minimization method. The values of activation energy were 191.632, 213.263 and 238.331 kJ·mol-1 and the values of pre-exponential factor were 11.641, 12.772, 11.666 min-1 respectively for the three reactions. The kinetic model was able to accurately predict the pyrolysis process of flame retarded HIPS.关键词
