摘要: 以UVA-340灯管作为人工老化加速光源,通过羰基指数及拉伸性能的变化,分析了抗老化剂对滴灌带耐老化性能的影响。结果表明,添加自制防老化母料的滴灌带防老化性能最佳,与未老化的试样相比,人工老化10、12 d和自然暴露老化120 d的试样的断裂伸长率保持率分别为94.3 %、84.0 %和61.9 %;用340 nm 荧光紫外灯,辐照度控制在0.68 W/m2、黑板温度为60 ℃、冷凝温度为50 ℃、光照3 h、冷凝3 h、风吹10 min等试验条件下,可模拟出人工加速光老化试验的老化速率是自然气候环境下暴露试验的10倍左右。

Abstract: UVA-340 lamp was used as an artificial acceleratedphotoaging source. The variation in carbonyl index, tensile strength, and elongation at break before and after aging was investigated, and the effect of antiaging agents on antiaging properties of drip irrigation tape was analyzed. It showed that the drip irrigation tapes with selfmade antiaging masterbatch had the best antiaging performance, compared with the 0 days aging sample, retention rate of elongation at break of the samples artificial aging for 10 days, 12 days and naturally exposed to 120 days aging were 94.3 %, 84.0 %, 61.9 %, respectively. UV340nm light at the condition of the radiation strength of 0.68 W/m2, blackboard temperature of 60 ℃, condensing temperature of 50 ℃, exposure time of 3 h, condensing time of 3 h, wind of 10 min, the aging rate was about ten times based on artificial accelerated photoaging more than that at natural environment.
