摘　　要：研究了一级乳化工艺条件下,乳化剂种类、油相配方及不同乳化器对乳化炸药爆炸性能和储存稳定性的影响,采用高低温循环试验考察制备乳化炸药的储存稳定性。试验研究表明:一级乳化(CYJ型乳化器)时,LZ27011乳化剂制备的乳化炸药储存稳定性、爆炸性能和微观结构均优于S/T乳化剂制备的乳化炸药;乳化剂为LZ27011时,CYJ型乳化器较JWL-YR乳化器的乳化效果更好;乳化剂(Span80和LZ27011的质量比为0.51.5)和乳化器确定时,油相配比对乳化炸药的储存稳定性有显著的影响,当油相组成复合蜡和150SN的质量比为3.21.0时,所制得的乳化炸药经34个高低温循环后,爆炸性能仍符合标准要求。Influence of emulsifying agent,oil phase formula and different emulsifiers on explosive performance and storage stability of emulsion explosive by one-step emulsification were studied. High-low temperature cycling test was used to evaluate storage stability of emulsion explosives prepared in this study. The experimental results show that storage stability,explosion property and microstructure of the emulsion explosive prepared by one-step emulsification（ LZ27011 emulsifying agent） is better than that prepared with Span80/T152. Using emulsifying agent LZ27011,The emulsion explosive made by CYJ emulsifier is more sustainable and stable than that by JWL-YR emulsifier. When m（ Span80） m（ LZ27011）is 0. 51. 5 and the emulsifier are determined,oil phase has a significant effect on the storage stability of emulsion explosives. In the oil phase,when m（ compound wax） m（ 150 SN） is 3. 21. 0,explosion performance of the emulsion explosive prepared here is still conforms to the standard GB18095—2000 after 34 cycles of high and low temperature test.
