Abstract

The invention relates to a novel polymer emulsifier used for emulsifying explosives and a preparation method thereof. The emulsifier is a novel emulsifier prepared from an esterification of polyisobutylene succinic anhydride and fatty alcohol-polyoxyethylene ether and an amination of the product and alcohol amine. The emulsifier has good emulsifying performance and excellent emulsifying stability and can be used for emulsifying explosives. Compared with the prior art, the invention has the characteristics of low production cost, large operating elasticity, easier realization of production process and the like.

Description

technical field [0001] The invention relates to an emulsifier mainly used for preparing emulsion explosives and a preparation method thereof. Background technique [0002] The performance of the emulsifier plays an important role in the quality of the emulsion explosive, and the performance of the emulsifier has a relatively important influence on the explosive performance and storage performance of the emulsion explosive. Therefore, the performance of emulsifiers has been paid more and more attention by the emulsion explosives industry. [0003] At present, the emulsifiers used in the production of emulsion explosives are mainly SPAN-80 and polybutylene butadiimine (single-hang, double-hang and multi-hang, etc.) emulsifiers. The advantage of SPAN-80 is that the source of raw materials is wide, the price is relatively low, it is easy to emulsify, and the latex matrix can be formed at a low temperature and low speed, but the molecular structure contains double bonds, which a...
