一种新型乳化炸药专用高分子乳化剂的研发与应用

以聚异丁烯丁二酸酐、山梨醇为原料合成聚异丁烯丁二酸山梨醇酯乳化剂,用红外光谱对产物进行结构表征。并通过与Span-80、T152作乳化力、乳胶基质形貌、乳胶基质稳定性的对比实验及该乳化剂在乳化炸药中的热安定性和爆炸性能来考察制备的乳化剂在乳化炸药中的应用情况。结果表明,该乳化剂的乳化力介于Span-80和T152之间,但用该乳化剂制备的乳胶基质的粒径更小、稳定性更高,制备的乳化炸药热安定性好,爆炸性能优异。

The Development and Application of A New Polymeric Emulsifier Designed for Emulsion Explosives

Polyisobutylene succinic acid sorbitol ester was synthesized using polyisobutylene succinic anhydride and sorbitol as raw material. The structure of the product was characterized by infrared spectrum. To investigate the application of the emulsifier in emulsion explosives, the emulsifying ability, the morphology and stability of the emulsion matrix, thermal stability and detonation performance preparaed with the product were tested. Compared to the emulsion and emulsion explosives prepared by Span-80 and T152 as emulsifiers, the rusults show that the emulsifying ability of the emulsifier is beween Span-80 and T152, but smaller size of the emulsion matrix and longer storage period. Besides, the detonation velocity is excellent, the thermal stability in emulsion explosives is good.
