| 摘 要： | 制备了聚异丁烯系列乳化剂，并系统研究了聚异丁烯系列乳化剂在不同类型乳化炸药中的应用效果。在现场混装乳化炸药中，聚异丁烯-醇胺乳化剂具有比聚异丁烯-酰胺乳化剂更好的应用效果。并且，其亲水基结构、疏水链长度和用量均对现场混装乳化炸药基质的流变性产生较大影响。当在聚异丁烯乳化剂中添加一部分小分子乳化剂后，所形成的乳化炸药基质黏度和储能模量有所提高，但是稳定性快速下降。然而，在包装乳化炸药中，聚异丁烯 酰胺乳化剂具有更好的应用效果。对于聚异丁烯 醇胺乳化剂而言，虽然所制备的乳化基质稳定性较好，但是用于化学敏化形成的包装乳化炸药时，其储存稳定性却下降显著。

| Abstract: | Polyisobutene series emulsifiers was synthesized, and their application in different types of emulsion explosives was studied systematically. In field mixed emulsion explosive, polyisobutene-alcohol amine emulsifiers have better application effect compared to polyisobutene-amide emulsifiers. Moreover, hydrophilic base structure, hydrophobic chain length and dosage have great influence on the rheological properties of field mixed emulsion explosive matrix. Upon addition of some small molecular emulsifiers to polyisobutene emulsifier, the viscosity and storage modulus of the emulsion explosive matrix improve, but the stability decreases rapidly. However, polyisobutene-amide emulsifier has better application effect in packing emulsion explosive. For polyisobutene-alcohol amine emulsifiers, although the stability of the prepared emulsion matrix is good, the storage stability of emulsion explosives decreases significantly. |
