聚醚聚氨酯泡沫塑料的辐射老化研究

Study on the Radiation Aging Effect of Polyether-urethane Foam

摘要: 研究了经电子束作用后聚醚聚氨酯(ETPU)泡沫塑料的辐射老化规律。采用气相色谱(GC)、热分析(TG)、扫描电镜(SEM)和透射电镜(TEM)技术,研究了材料经辐照后其辐解气体产物的种类和生成量以及材料的热性能、微观相分离和表观形貌的变化。

Abstract: The radiation aging effect of polyetherurethane(ETPU) foam was studied in detail. The gas products from irradiated samples were analyzed quantitatively and qualitatively by GC, the thermal property and microphase separation were determined by TG and TEM, and the microscopic form by SEM.
