摘要
研究了脂肪族、聚醚类二元醇扩链剂和三元醇交联剂对NEPE推进剂胶片的高温力学性能影响。结果表明,脂肪族二元醇扩链剂可提高NEPE推进剂胶片的高温力学性能,但会引起硝酸酯增塑剂析出;选择适当种类、含量的聚醚类二元醇可显著提高胶片的高温力学性能;三元醇交联剂使NEPE推进剂粘合剂胶片的最大抗拉强度有所提高,最大延伸率降低。
The effects of chain exteuders and cross linkers on the mechanical characteristics of the binder film of the NEPE propellant at 50℃ were experimentally studied. The results indicate that the aliphatie and low molecular polyether diols （chain extenders） improves the mechanical characteristics of the binder films at high temperature, and the three types of triols （cross linkers） increases the maximum stress of the binder film and decreases the maximum elongation of the bind film. It is found that the aliphatie diols might cause the exudation of nitrate esters from the binder film during the curing process.
