摘要
通过荧光紫外人工加速老化试验对聚苯乙烯(PS)样条的老化行为进行了研究。利用力学性能和黄色指数测试、FTIR及TG分析对老化后的试样进行了表征。结果表明:PS的化学老化主要受光辐照的影响,温度对老化起促进作用而,水分对老化的影响不明显。
The aging behavior of PS was studied by UV accelerated weathering test. The PS samples after aging were characterized by mechanical property and yellow index test, FTIR and TG analysis. The results show that UV radiation is the main factor for the chemical aging of PS, the temperature promotes the aging behavior, but humidity has little effect on the aging behavior.
