摘　　要：文章介绍了一种新型乳化剂的制备及其在乳化炸药中的应用。采用马来酸酐(MA)和Span80反应制备双子型非离子乳化剂MA-Span80,并与聚异丁烯双丁二酰亚胺(T152)以质量比11制备复合乳化剂,来研究糠蜡型复合油相专用乳化剂。用乳化剂与复合油相制备乳胶基质,测试乳胶基质的黏度和储存稳定性。通过测定MA-Span80及其复合乳化剂在乳化炸药中的爆轰性能,探讨其在乳化炸药中的应用。结果表明:相比于Span80乳化剂,MA-Span80及其复合乳化剂更适用于糠蜡型复合油相,制备的乳化炸药具有更长的储存期。Preparation of a new type of emulsifier and its applications in emulsion explosive was described. The gemini nonionic emulsifier MA-Span80 was synthesized through the reaction of maleic anhydride and Span80,which subsequently was used for the preparation of compound emulsifier together with T152 at the mass ratio of 1： 1. By such formula,special emulsifiers for composite oil phase containing bran wax were researched. Emulsion matrix was prepared by the emulsifiers with composite oil phase,and the viscosity and storage stability was tested. The detonation performance of MASpan80 and the compound emulsifier were inspected for their practical applications on emulsion explosives. The results show that MA-Span80 and its compound emulsifier are more suitable for composite oil phase containing bran wax,and the emulsion explosives made from them have longer storage period in comparison with Span80.
