摘　　要：以冲击强度为特性指标,将2种环氧泡沫塑料试样在特定温度下进行加速老化试验,根据试验结果估算了2种环氧泡沫塑料在23℃下的寿命。结果表明,2种环氧泡沫塑料在23℃下的寿命均为28年,自制的环氧泡沫塑料耐高温老化性能更佳。In this paper, by means of the impact strength of a sample which passes through air aging test, the storage life of two kinds of epoxy foam at 23 ℃ was predicted. The experimental results showed that the storage life of both kinds of epoxy foam at 23 ℃ would be 28 years. The high-temperature resistance aging performance of the homemade epoxy foam was better.
