通过不同类型溴系阻燃剂与Sb2 O3复配制备阻燃HIPS,考察不同类型溴系阻燃剂对阻燃HIPS耐紫外光老化性能影响,结果表明不同类型溴系阻燃对阻燃HIPS的影响有很大差异(300 h氙灯老化的不同类型溴系阻燃HIPS色差值从3．5到56．8),通过分析不同溴系阻燃剂对阻燃HIPS耐候性能的影响,发现阻燃剂结构的稳定性是影响耐候性的主要因素,相同结构下随着溴含量增加,耐候性降低。
Through different types of brominated flame retardants and Sb2 O3 complex to prepare flame retardant HIPS,the effect of different types of brominated flame retardants on flame retardant HIPS UV resistant aging proper-ty was examined. The results show the effects of different types of brominated flame retardant on the fire-retardant HIPS are very different ( color values of different types brominated flame retardant HIPS by xenon lamp aging 300 h are from 3. 5 to 56. 8),by analyzing the effect of different flame retardant brominated flame retardant HIPS weathe-ring performance,find that a stable flame structure is the main factor affecting the durability. With the increase of the content of bromine to the same structure,weather resistance is reduced.
