ABSTRACT:The factors affecting the viscosity of oil phase materials and the effect of viscosity on the storage stability of emulsion explosives were investigated in this paper. The results showed that the emulsifier was the crucial factor in the viscosity of composite oil phase materials, in which the polymeric emulsifier had a significant impact on the viscosity of composite oil phase materials. Whereas within the frequently-used range of emulsifiers for composite oil phase materials, the content change of emulsifier had few significant impact on the viscosity of oil phase materials. The study also found that the influence of composite oil phase materials on the storage stability of emulsion explosives is mainly determined by the formula composition, the storage stability of emulsion explosive matrices had a great difference which was prepared by different formula composition but approximate viscosity of composite oil phase materials.
