摘要

利用原位红外对星型苯乙烯-丁二烯-苯乙烯三嵌段共聚物(SBS)和线型SBS在不同热、氧、光照条件组合下老化时产生的CO₂的生成速率,建立多因素耦合老化动力学模型并进行条件敏感性分析,与传统室内人工加速老化试验后黄色指数、红外光谱(FT-IR)、X射线光电子能谱(XPS)等数据进行对比验证。结果表明:不同条件下的敏感性分析中光照是影响两种结构SBS老化的最主要因素,其次是温度和氧气浓度;相同条件下的敏感性分析中星型SBS对温度更敏感,线型SBS对光照强度和氧气浓度具有更高的敏感性;星型SBS和线型SBS在传统80℃热氧老化后黄色指数升至约79.41和69.56,在60℃热氧光老化后黄色指数升至约54.55和51.28,在纯紫外老化后黄色指数升至约26.90和30.44。热氧老化星型SBS容易老化,纯紫外老化线型SBS易老化与敏感性分析结果一致,确定了以CO₂释放量作为老化评价方法的合理性。

Abstract

Utilizing in-situ infrared spectroscopy to investigate the CO₂ generation rates of star-shaped styrene-butadiene-styrene triblock copolymer (SBS) and linear SBS under different combinations of heat,oxygen,and light exposure,a multi-factor coupled aging kinetic model was established and subjected to sensitivity analysis.The results were validated by comparing with data from traditional indoor accelerated aging tests,including yellow index,Fourier transform infrared spectroscopy (FT-IR),and X-ray photoelectron spectroscopy (XPS).The results indicated that in sensitivity analyses across different conditions,light exposure was the primary factor affecting aging of both SBS structures,followed by temperature and oxygen concentration.Under identical conditions,star-shaped SBS exhibited greater sensitivity to temperature,while linear SBS showed higher sensitivity to light intensity and oxygen concentration.After conventional 80℃ thermo-oxygen aging,the yellow index of star-shaped SBS and linear SBS increased to approximately 79.41 and 69.56,respectively.Following 60℃ thermo-oxygen-light aging,the yellow index rose to about 54.55 and 51.28,respectively.Under pure UV aging,the yellow index reached approximately 26.90 and 30.44,respectively.The thermal-oxygen aging results for star-shaped SBS indicated susceptibility to aging,while linear SBS showed susceptibility to pure UV aging.These findings aligned with sensitivity analysis outcomes,confirming the validity of using CO₂ release as an aging evaluation method.
