Problems solved by technology

[0004] At present, there are three types of emulsifiers commonly used in emulsion explosives on the market: the first type is SP-80 emulsifier (sorbitan monooleate), which is also the most widely used emulsifier for emulsion explosives in China. Its advantage is emulsification Strong capacity, low shearing force and low cost, but the amount used in emulsification is relatively large, and the strength of the emulsified oil film is small, and the storage stability of the produced emulsion explosives is short
The second category is emulsifier succinic anhydride derivatives. Although emulsifiers succinic anhydride derivatives are easy to preserve, they have high technological requirements in the production process, and there are many control contents, and the overall production is complicated, which is not conducive to industrial production
The third type of emulsifier is a compound emulsifier. Although it is a compound emulsifier, it still has defects. Such problems reduce the safety of explosive production and do not meet the actual needs of the development of my country's explosives industry.

Abstract

The invention discloses a special liquid integrated oil phase emulsifier which comprises the following components in parts by weight: 71-80 parts of an SP-80 emulsifier, 14-25 parts of a polymer emulsifier and 0-9 parts of a soybean lecithin emulsifier. Compared with the prior art, the emulsifier has higher viscosity and lower acid value, the interface strength is enhanced, an emulsion explosive prepared from the emulsifier has excellent storage stability and detonation performance, the preparation process is simple, and the emulsifier is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of emulsion explosives, in particular to a preparation method of a special emulsifier for liquid integrated oil phase. Background technique [0002] The emulsion explosive uses the supersaturated solution of oxidant salt such as ammonium nitrate as the dispersed phase, and the combustible oil phase as the continuous phase. Under the action of the emulsifier, the tiny droplets of the dispersed phase are evenly dispersed in the continuous phase of the oil phase to form an oil Water-encapsulated industrial explosives. It has a series of advantages such as excellent water resistance and explosive performance, wide source of raw materials, simple production process and long storage stability period. It has been widely recognized at home and abroad, and its output has increased rapidly in recent years. [0003] The emulsifier suitable for emulsion explosives is a type of surfactant with a lipophilic-hydrophilic b...
