考察了溴系阻燃剂、磷氮系阻燃剂对聚对苯二甲酸丁二醇酯（ PBT）力学性能、耐光老化性能的影响，还研究了酸吸收剂对阻燃PBT材料的力学性能、紫外线稳定性的影响。结果表明，钙锌稳定剂能提高卤系阻燃材料的耐侯性能，无卤阻燃PBT的耐侯性能优于卤系阻燃PBT（1000h，△E≤3）。
The effects of the brominated flame retardants , phosphorus-nitrogen flame retardant on mechanical properties and light-proof aging properties of polybutylene terephthalate (PBT),and Influence of the acid acceptor on the mechanical properties and UV stability of the flame retardant PBT materials were researched.Results showed that calcium-zinc stabilizer can improve the weathering resistance performance of phosphorus -containing flame re-tardant materials,For halogen free flame retardant PBT ,the weathering resistance performance is better than that of phosphorus-containing flame retardant PBT.
