摘要

聚烯烃的自然老化是光照、温度、湿度和氧气多种环境因素综合作用的结果，但长期以来，无法通过实验室加速得到模拟综合条件下的老化结果. 本文采用自主设计开发的多因素耦合老化评价系统，可以实现光照、温度、湿度和氧气条件的可控加载，测定高分子材料在不同条件组合下老化时产生的气相降解产物(如CO

)的生成速率，以此来评价材料的稳定性. 以聚丙烯(PP)和聚乙烯(PE)为典型体系，建立了二者关于温度、光照强度、湿度和氧气浓度的单因子老化速率方程，并基于此建立了PP和PE的多因素耦合老化动力学模型. 通过测定不同条件下的老化速率，拟合得到了PP和PE的多因素耦合老化动力学方程，并计算得到了PP和PE的全国“老化速率地图”和逐月“老化速率时间谱”，对PP和PE的应用提供了重要的指导. 进行了PP和PE对不同条件因子的敏感性分析. 研究发现，PP对光照强度和湿度的敏感性显著高于PE，对氧气浓度的敏感性略高于PE，而对温度的敏感性要低于PE.

Abstract

Natural aging of polyolefins is the comprehensive result of multiple environmental factors

such as UV irradiation

temperature

humidity and oxygen. But till now natural aging result is difficult to be simulated by accelerated aging. In this study

a lab-developed system was used to realize an

in situ

multi-factor aging evaluation under adjustable UV irradiance

temperature

humidity and oxygen concentration. Gaseous degradation products (CO

is typical) were detected and the formation rate of CO

was exploited to evaluate the stability. High formation rate (high aging speed) corresponds to low stability. By this system

single-factor aging speed equation of aging speeds of polypropylene (PP) and polyethylene (PE) versus UV irradiance

or temperature

or humidity

or oxygen concentration were established. Furthermore

multi-factor aging speed kinetics models of PP and PE were established and the parameters were fitted. Based on the multi-factor aging kinetics equations

the yearly aging speed “maps” in China and monthly aging speed “spectra” in some cities of PP and PE were drawn. This information is instructive to practical outdoor applications of PP and PE. The sensitivity of PP and PE to environmental factors was analyzed. It was found that PP is much more sensitive to irradiance and humidity than PE

a little more sensitive to oxygen concentration than PE

but is less sensitive to temperature than PE. This strategy can also be used for other polymer materials to establish their own multi-factor aging kinetics equations.
