| 目的 研究面向典型高分子材料应用的大气环境严酷度分类方法。方法 开展聚苯乙烯在我国10个典型大气环境地区的自然暴露试验，对比分析聚苯乙烯表面及力学性能的变化规律及差异，确定大气环境严酷度评估参数，依据评估参数量值对大气环境严酷度分类分级。结果 聚苯乙烯表面的黄色指数随时间呈线性增大，且各环境地区的规律一致，其老化模型中的常数可作为大气环境严酷度评估的性能参数。太阳辐射和高温高湿是影响聚苯乙烯劣化的主要环境因素。结论 以聚苯乙烯性能为大气环境严酷度评估参数，可将我国大气环境严酷度划分为6个等级。 |

| Objective To study the classification method of atmospheric environment severity for the application of typical polymer materials. Method The natural environment test of polystyrene was carried out in ten typical environment areas of China. The change rules and variation of surface and mechanical properties of polystyrene were compared and analyzed. The parameters of atmospheric environmental severity were determined, and the atmospheric environmental severity was classified according to the parameters evaluated. Results The yellow index of polystyrene surface increased linearly with time and the laws were consistent. The constant in the aging model can be taken as the performance parameters for evaluation of the atmospheric environment severity. Solar radiation and high temperature and humidity were the main environmental factors affecting the degradation of polystyrene. Conclusion The performance of polystyrene can be used as the evaluation parameter of atmospheric environment severity, and atmospheric environment severity of China can be divided into six levels |
