Easy-to-sensitize compound emulsifying agent and preparation method thereof

The invention provides an easy-to-sensitize compound emulsifying agent. The compound emulsifying agent contains the following components in percentage by weight: 40% to 50% of a surfactant, 40% to 55% of a wetting and stabilizing agent, and 5% to 10% of a sensitization accelerating agent, wherein the surfactant is one or a mixture comprising more than two components selected from polyisobutene succinimide, polyisobutene di-succinimide, sorbitan monooleate (Span 80) or dehydrated xylitol monooleate; the wetting and stabilizing agent is one or a mixture comprising more than two components selected from oleic acid, lecithin, liquid paraffin or fatty acid; the sensitization accelerating agent is one or a mixture comprising more than two components selected from citric acid, ammonium nitrate, diluted hydrochloric acid, fatty acid or oleic acid. The compound emulsifying agent is stable in quality, generates bubbles which are uniform, tiny and stable, and is controllable in the aspects of explosive density and sensi
