摘要
Abstract
Brominated styrene-butadiene rubber (BSBR) was prepared by using dichloroethane as a solvent,SbCl3 as a catalyst and BrCl as a brominating agent.The effect of BrCl dosage on the bromine content of BSBR was investigated.Subsequently,BSBR was mixed with polystyrene by a solution method,and the effect of the bromine content of BSBR on the flame-retardant properties of PS composites was investigated by thermogravimetric analysis,limiting oxygen index (LOI) and cone calorimeter.The results indicated that BSBR achieved a maximum bromine atom percentage of 33.17 ％ when the dosage of BrCl was set as 70 mL.The introduction of BSBR could effectively improve the flame retardancy of PS.The higher the bromine content in BSBR,the better the flame-retardant effect on PS.As a result,a maximum LOI of 30.8 vol ％ was achieved for the flame-retardant PS.Moreover,LOI of the flame-retardant PS increased with an increase of BSBR content,but the total heat release of the combustion decreased.In addition,the release amount of CO increased due to incomplete combustion.关键词
