Description
Technical field
The present invention relates to a kind of emulsifying agent, be specifically related to LZ2735 emulsifying agent and preparation method thereof.
Background technology
Emulsification blasting agent mixing vehicle is ore deposit demolition site in the open, carries out continuous emulsification and sensitization on emulsification blasting agent mixing vehicle
Production and processing emulsion, and the automated machine equipment integrating transport, preparation, powder charge being delivered directly in big gun hole.
The emulsion of preparation is water-in-oil type (w/o), without cap-sensitivity, has safety good, and preparation technology is simple, and detonation property is excellent
The feature such as different.Emulsion is mainly made up of aqueous inorganic oxidizer salt solution, oil phase material and emulsifying agent.By the work of emulsifying agent
With making the aqueous inorganic oxidizer salt solution of more than 90wt% less than 10wt% oil phase material as continuous phase in mechanical dispersion power
Effect emulsified, formed water-in-oil type (w/o) emulsion matrix.Owing to emulsion matrix is non-thermodynamic stable system, divided
The dispersion phase being dispersed in continuous phase exists with fine droplets, easily gathering, breakdown of emulsion.Emulsion matrix stability depends on interface
Film strength, and interface film strength is closely related with the interfacial film thickness of the structure of emulsifying agent and formation.Therefore, emulsifying agent is
Affect the main cause of emulsion matrix stability.Emulsification blasting agent mixing vehicle is ore deposit demolition site in the open, at emulsification blasting agent mixing
Carry out continuous emulsification and sensitization production and processing emulsion on car, and be delivered directly in big gun hole collect transport, preparation, powder charge in
The automated machine equipment of one.The emulsion of preparation is water-in-oil type (w/o), without cap-sensitivity, has safety good, system
The features such as standby technique is simple, and detonation property is excellent.Emulsion is mainly by aqueous inorganic oxidizer salt solution, oil phase material and emulsifying
Agent forms.Made inorganic oxidizer of more than 90wt% less than 10wt% oil phase material as continuous phase by the effect of emulsifying agent
Saline solution is emulsified in the effect of mechanical dispersion power, forms the emulsion matrix of water-in-oil type (w/o).Due to emulsion matrix right and wrong
Thermodynamic stable system, the dispersion phase being dispersed in continuous phase exists with fine droplets, easily gathering, breakdown of emulsion.Latex
Matrix stability depends on interface film strength, and interface film strength is close with the interfacial film thickness of the structure of emulsifying agent and formation
Cut is closed.Therefore, emulsifying agent is the main cause affecting emulsion matrix stability.
At present, the emulsifying agent in emulsification blasting agent mixing vehicle application is mainly Sp-80.Patent EP01429 proposes
Emulsion prepared by emulsifying agent, and the compactness of its emulsifying film formed and film-strength are the most very poor, therefore stability is the lowest.Steady for improving
Qualitative addition emulsion stabilizer serves certain effect, but effect is the most undesirable.Had in recent years and macromolecule emulsifier was applied
Propose to replace carboxylic with macromolecule alkyl in the preparation of emulsion, such as patent USP4708753, USP4828633 and GB2216128
Succimide family macromolecule emulsifying agent is prepared in acid and polyamine compounds reaction, although improve emulsifying film strength and pliable and tough
Property, but its equal relative molecular weight of number is relatively big, and hydrophilic group is few, therefore emulsifying power is low, and the shear strength needed for emulsifying is high.This kind of
Emulsifying agent high temperature easily decomposes generation ammonia and carbon dioxide, and the emulsion matrix of preparation has certain detonation sensitivity, inapplicable
In emulsification blasting agent mixing vehicle.The polyisobutylene series emulsifier viscosity of domestic production is big, does not meets emulsification blasting agent mixing vehicle requirement,
Therefore it is rarely applied to blasting agent mixing vehicle commercial production.At present, the emulsifying agent in emulsification blasting agent mixing vehicle application is mainly Sp-80.
Patent EP01429 proposes to prepare emulsion with Sp-80 for emulsifying agent, and the compactness of its emulsifying film formed and film-strength are the most very
Difference, therefore stability is the lowest.Serve certain effect for improving stability addition emulsion stabilizer, but effect is the most undesirable.Closely
Have the preparation that macromolecule emulsifier is applied to emulsion year a bit, as patent USP4708753, USP4828633 and
GB2216128 proposes to prepare succimide family macromolecule emulsifying with macromolecule alkyl substituted carboxylic acid and polyamine compounds reaction
Agent, although improve emulsifying film strength and pliability, but its equal relative molecular weight of number is relatively big, and hydrophilic group is few, therefore emulsifying
Efficiency is low, and the shear strength needed for emulsifying is high.This kind of emulsifying agent high temperature easily decomposes generation ammonia and carbon dioxide, the latex of preparation
Substrate has certain detonation sensitivity, is not suitable for emulsification blasting agent mixing vehicle.The polyisobutylene series emulsifying agent of domestic production
Viscosity is big, does not meets emulsification blasting agent mixing vehicle requirement, therefore is rarely applied to blasting agent mixing vehicle commercial production.
