The powdered emulsified explosive prepared with the emulsifier has high explosion performance, high stability and long storing period.
Description
Technical field
The present invention relates to a kind of for powdery emulsifying explosive emulsifying agent and preparation method thereof.
Background technology
Powdery emulsifying explosive is a kind of civil rendrock, it is to be that decentralized photo, fuel agent oil phase are continuous phase by aqueous oxidizing agent solution, be prepared into the emulsion matrix of water-in-oil type, the powder type explosive that then uses drying process with atomizing to make by the effect of emulsifying agent. It is a kind ofly both to have possessed Lithium Oxides By Detonation With Emulsion Explosive function admirable, component and do not contain TNT, has the characteristics of certain water repelling property, possesses again the powdery ammonium ladder detonator stable storage, uses the novel emulsion explosive of the advantage such as more flexible.
Water content about 4% in the powdery emulsifying explosive prescription, water content well below common emulsion 10%～14%, its emulsifying temperature is 130 ℃～140 ℃, common SP-80 emulsifying agent can not satisfy instructions for use, there is no at present emulsifier special, generally adopt succimide high score subclass emulsifying agent. ZL91107080.X proposes a kind of emulsified powdered nitramon and manufacture method thereof, the emulsifying agent that adopts is polyisobutene succinimide (being called for short 8045), powdery emulsifying explosive that ZL93117971.8 proposes and preparation method thereof, the emulsifying agent that requires is succimide series emulsifying agent, as mono butonediimide, two succimide or (with) their mixture. Permitted Detonator for Coal Mining powdery emulsifying explosive and manufacture method thereof that ZL00112441.2 proposes, the emulsifying agent of employing is mono butonediimide, two succimide, many succimides or their mixture. These three patents all propose to adopt succimide to make emulsifying agent, as everyone knows, succimide is to be made by the reaction of the ethyleneamines such as polyisobutenyl maleic anhydride and triethylene tetramine or TEPA, be the amide-type macromolecular compound, the preparation method of succimide sees USP4234435, ZL95107994.8 for details. Succimide is always as lubricant ashless dispersant, and the domestic trade mark has T-152, the T-153 of Lanzhou refinery factory and T-154, the T-155 of Jinzhou. Its Main Function is the carbon distribution that disperses lubricating oil to wear and tear at a high speed and produce, and prevents deposition. Emulsification is a kind of ad hoc fashion of disperseing, and emulsifying agent can be used as a kind of dispersant, but dispersant is not equal to emulsifying agent. Succimide is a kind of preferably dispersant, during as emulsifying agent, because it has macromolecular structure, greatly improved the emulsification film strength, but its polar group hydrophily is relatively poor, and is sterically hindered larger, and hydrophilic radical is little, so emulsifying power is lower. Need higher emulsion strength during for the production of powdery emulsifying explosive, the fully emulsification of part water is often arranged, affect powdery emulsifying explosive and bring into play maximum brisance.
ZL96100379.0 proposes a kind of emulsifying agent for emulsion and preparation method thereof, carry out esterification with poly-hydrocarbon carboxylic acids or acid anhydrides with polyalcohol under the effect of catalyst, it is good and be suitable for preparing water-in-oil type (W/O) macromolecule emulsifier of high storage stability energy emulsion to obtain a kind of emulsifiability. This emulsifying agent molecular structure is for the emulsion technological design, and its hydrophilic group is the ester class formation, nonnitrogenous and amide group, compare with succimide, emulsifiability improves a lot, but the emulsified bases of preparation is softer, become the powder difficulty, therefore be 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 product of a kind of poly-hydrocarbon carboxylic acids or acid anhydrides and hydramine, but it for be drilling fluid, can not be most appropriate to powdery emulsifying explosive.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of easy emulsification, and emulsion stability is good, and is beneficial to powdery emulsifying explosive emulsifying agent and preparation method thereof that explosive is sprayed into powder.
Powdery emulsifying explosive emulsifying agent of the present invention is the product of hydrocarbon carboxylic acids or alkyl acid anhydrides and 2～3 kinds of alcohol amine compound mixtures. Wherein the alkyl molecular weight of hydrocarbon carboxylic acids or alkyl acid anhydrides is 900～2000,950～1500, and alkyl can be selected from polybutene, polyisobutene, ethylene-propylene copolymer etc.; Carboxylic acid or acid anhydrides are selected from maleic anhydride, fumaric acid anhydride etc. and corresponding acid, are preferably maleic anhydride. Alcohol amine compound mixture wherein is the mixture of MEA, diethanol amine and triethanolamine, the amount of mixture of alcohol amine compound is 3～50% of hydrocarbon carboxylic acids or alkyl acid anhydrides weight, be preferably 5～20%, the weight of the mixture of alcohol amine compound consists of:
MEA 10%～60%
Diethanol amine 30%～60%
Triethanolamine 0%～40%
Be preferably:
MEA 20%～40%
Diethanol amine 40%～60%
Triethanolamine 0%～20%.
Powdery emulsifying explosive of the present invention with the preparation process of emulsifying agent is: hydrocarbon carboxylic acids or alkyl acid anhydrides and pure amine blends react in the presence of catalyst, catalyst is NaOH or the KOH solution that concentration 20w%～50w% is preferably 25w%-35w%, and the catalyst addition is that the 0.02w%～1.5w% of reaction raw materials is preferably 0.5w%-1.0w%. Reaction condition is: be preferably 150-200 ℃, pressure-0.02 MPa～0.08MPa 100 ℃～220 ℃ of temperature to be preferably-0.02MPa～0.06MPa condition under, react 1～10 hour best 3～6 hours.
Powdery emulsifying explosive of the present invention with emulsifying agent owing to selected mixing hydramine and hydrocarbon carboxylic acids or the alkyl anhydride reaction of suitable proportion, reduced steric effect in the synthetic reaction, can make emulsifying agent obtain larger hydrophilic radical, and this hydrophilic radical stable in properties, the stability of the performance of raising powdery emulsifying explosive in production and storage process. Adopt another advantage of mixing hydramine to be that product not only contains ester group, amide group, and hydrocarbon carboxylic acids or alkyl acid anhydrides and MEA, diethanol amine or (with) product of triethanolamine mixture is comprised of the multicomponent surface reactive material, Water-In-Oil (W/O) type emulsification system is had cooperative effect, form compound emulsifying agent. Compare with the product of independent a kind of alcohol amine compound, not only improved emulsifiability, and the continuous compactness of emulsifying film is increased, thereby further improve the bin stability of explosive.
Emulsifying agent of the present invention has well emulsify performance, emulsion stability, is easy to into powder with the powdery emulsifying explosive of its preparation, has good detonation property and bin stability. Compare with independent a kind of pure amine reaction product with T-154, T-155 or alkyl acid anhydrides, use emulsifying agent of the present invention, can reduce emulsifier, corresponding reduction explosive cost. In addition, also can suitably reduce emulsion strength, make emulsification condition mild, so it is better to prepare the production security of powdery emulsifying explosive with emulsifying agent of the present invention. Emulsifying agent preparation method of the present invention is simple, and raw material is easy to get, and need not course of reaction is carried out precision control.
