Objective To study the aging property of envelop material for a certain type of airship and the effect of dif-ferent environmental factors on the airship envelop material. Methods Based on the operation environment of the airship, laboratory accelerated aging combination test was carried out for the two airship envelop materials URETEK-3216LV and HD-150. Results The deterioration law of breaking force of the two airship envelop materials after accelerated aging in dif-ferent environmental conditions was obtained. Conclusion The test results showed that high-humidity environment had the greatest influence on the ageing performance of URETEK-3216LV, while high-temperature environment had the greatest in-fluence on the ageing performance of HD-150. The weatherability of URETEK-3216LV was better than that of HD-150.%目的：研究某飞艇蒙皮材料加速老化性能，以及不同环境因素对飞艇蒙皮材料老化的影响。方法根据某飞艇的使用环境，对 URETEK-3216LV 和 HD-150两种飞艇蒙皮材料进行了实验室加速老化组合试验。结果得到了不同环境条件下两种飞艇蒙皮材料加速老化后断裂强力退化规律。结论 URETEK-3216LV 材料对高湿环境最为敏感，而 HD-150材料对高温环境最为敏感。 URETEK-3216LV 材料耐候性能比 HD-150材料耐候性强。
