Abstract
The invention discloses a preparation method of an emulsifier for electric blasting. The method comprises the following steps of: stirring sorbitol, adding an aqueous phosphorous acid solution and heating the mixture to 115-150 DEG C; adding 500-530kg of oleic acid into a reactor, and stirring the mixture; slowly adding an aqueous sodium hydroxide solution into the reactor and quickly heating the reactor to 210 DEG C; maintaining the temperature of the reactor for 3 hours; sampling, stirring the mixture and assaying the acid value, the specific viscosity and a measured hydroxyl value; when the vacuum pressure reaches 0.06-0.11MPa, filtering the mixture in vacuum, standing for 10-12 hours and cooling; and uniformly mixing lecithin and T-152 emulsifier. In the method, mixed hydramine in a proper proportion is selected to react with carboxylic acid, thereby the steric effect in the reaction is reduced, and the emulsifier can obtain larger hydrophilic groups; and moreover, the hydrophilic groups have stable property so that the property stability of powdered emulsion explosives in the processes of production and storage is improved.
Description
Technical field
The invention belongs to the preparation method of powdery emulsifying explosive emulsification reagent technical field, particularly a kind of emulsifier for electric blasting.
Background technology
Powdery emulsifying explosive is a kind of civil blast explosive, and it is to be that disperse phase, combustible agent oil phase are external phase by aqueous oxidizing agent solution, is prepared into the emulsion matrix of water-in-oil-type, the powder type explosive that uses drying process with atomizing to make then by the effect of emulsifying agent.It is a kind ofly both to have possessed that the emulsion explosive blast performance is good, component does not contain TNT, has the characteristics of certain water repelling property, possesses the powdery ammonium ladder detonator shelf-stable again, uses the novel emulsion explosive of advantage such as more flexible.
ZL96100379.0 proposes a kind of emulsifying agent that is used for emulsion explosive and preparation method thereof, carry out esterification with poly-hydrocarbon carboxylic acids or acid anhydrides with polyvalent alcohol under the effect of catalyzer, it is good and be suitable for preparing the water-in-oil-type macromolecule emulsifier of high storage stability energy emulsion explosive to obtain a kind of each form a social stratum performance.This emulsifying agent molecular structure is that its hydrophilic group at the emulsion explosive technological design is the ester class formation, does not contain and the jealous woman amine groups, compares with succimide, emulsifying property improves a lot, but the emulsifying base of preparation is softer, becomes the powder difficulty, therefore is unsuitable for producing powdery emulsifying explosive.Relate to a kind of emulsifying agent in the disclosed water-base drilling fluid of WO96/40835, comprised the reaction product of a kind of poly-hydrocarbon carboxylic acids or acid anhydrides and hydramine, but it at be drilling fluid, can not be most appropriate to powdery emulsifying explosive.
Summary of the invention
The invention provides a kind of easy emulsification, emulsifying stability is good, and is beneficial to the preparation method that explosive is sprayed into the emulsifying agent that the powdery emulsifying explosive of powder uses.
A kind of preparation method of emulsifier for electric blasting may further comprise the steps:
