摘　　要：利用均匀设计法,研究了人工老化环境(温度和光辐照度)对不同配方地膜耐老化性能的影响。结果表明:采用均匀设计法,仅通过5次试验即得到了人工紫外线老化环境变化对地膜产品耐老化性能的影响规律;光辐照度是不添加抗老化剂地膜老化的主要影响因素,光辐照度越高,则地膜力学性能下降越严重;光照温度是添加抗老化剂地膜老化的主要影响因素,光照温度越高,地膜耐老化性能越差。The influence of artificial aging environment（temperature and light irradiance）on ageing resistance performance of different formulation plastic films was studied by uniform design method.The results show that using uniform design method,the effect of the change of artificial ultraviolet aging environment on the aging resistance of plastic film products was obtained through 5 tests.Light irradiance was the main influencing factor of plastic films aging without adding anti-aging agent.The higher the light irradiance,the more serious the mechanical properties of plastic films will decrease.Illumination temperature was the main influencing factor to increase the aging of plastic films with anti-aging agent.The higher the illumination temperature,the worse the aging resistance of the plastic films.
