【摘要】 以丁羟推进剂为例,从其氧化剂、黏合剂、化学功能组分等化学组分和碳碳双键、羟基、环氧基、分子质量等结构特征的变化,以及这些变化所产生的脱湿现象、氧化交联反应等为识别判据的几个方面,综述了推进剂老化化学识别的国内外研究进展。指出了开展化学变化及其效应的综合运用、化学组分空间位置变化研究、无损检测新技术应用等3方面进一步研究的问题,并展望其发展前景。更多还原

【Abstract】 Taking HTPB propellant as an example,the research progress of chemical identification on aging of propellant at home and abroad was reviewed from several aspects of changes in chemical compositions of its oxidizing agents,adhesives,chemical function composition and so on,and in structural characteristics of carbon carbon double bond,hydroxyl,epoxy,molecular weight and so on,and the dehydration phenomenon,oxidation crosslinking reaction etc.caused by these changes as identification criteria.The further research problems of developing the comprehensive uses of chemical changes and their effects,the research of spatial location changes of chemical composition and the application of nondestructive testing technology were pointed out and the future prospects were also proposed.更多还原
