Problems solved by technology

[0005] CN102675006A discloses a product obtained by esterification of polyhydrocarbyl carboxylic acid anhydride and polyglycerol. The emulsifier has good performance, but it belongs to an ester type emulsifier. When it is used to prepare emulsion explosives, the emulsion explosive matrix may be slightly soft. Formula design or application may be subject to certain restrictions

Abstract

The invention relates to a novel emulsifier mainly used for an emulsion explosive and a preparation method of the novel emulsifier. The emulsifier is the novel emulsifier obtained by carrying out esterification reaction on polyisobutylene succinic anhydride and polyglycerol, and then carrying out amination reaction on the obtained exterification product and alkylol amine. The emulsifier has good emulsifying property and can be used for preparing the emulsion explosive.

Description

technical field [0001] The invention relates to an emulsifier mainly used for preparing emulsion explosives and a preparation method thereof. Background technique [0002] Emulsifier is a key and important component used in the emulsion explosive industry. The performance of the emulsifier determines the explosive performance and storage performance of the emulsion explosive. Therefore, the preparation of emulsifiers with better emulsifying properties has received extensive attention from the emulsification 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 it is easy to emulsify, and it can form a latex matrix at a lower temperature and a lower rotational speed, but the molecular structure contains double bonds, which are easy to demulsify and crystallize after being oxidized. The storage ti...
