Abstract
A processing method of an emulsion (adhesive) matrix with good thermal safety relates to an emulsion explosive processing method. In the formula of the emulsion (adhesive) matrix, a water phase accounts for 91.0-95.2 % of the total weight; an oil phase accounts for 4.0-7.0% of the total weight; and an emulsifier accounts for 0.8-3.0% of the total weight. The three components are mixed and emulsified. The invention is characterized in that urea which accounts for 0.2% the total weight of a water phase material (including clean water) is added into the water phase component for heating and dissolution; methylpentachlorostearate or chlorinated paraffin-70 or chlorinated paraffin-52 or chlorinated paraffin-42 which accounts for 1.0-9.0% the total weight of the oil phase material is added into the oil phase component together with the emulsifier for heating and melting; and materials such as the water phase, the oil phase, the emulsifier and the like which are prepared by the above method undergo shearing, stirring and emulsification by a special-purpose emulsification device to form the emulsion (adhesive) matrix. The invention has the following advantage: an ammonium nitrate decomposition inhibitor is added into the water phase component and a fire retardant is added into the oil phase component so as to raise the thermal safety of the matrix.
Description
Technical field:
The present invention relates to the working method of emulsion [explosive, particularly a kind of working method with good thermal security emulsification (glue) matrix.
Background technology:
Emulsification (glue) matrix is the work in-process of emulsion [explosive, becomes emulsion [explosive behind its process chemical sensitization or the physical sensitization.The component of emulsification (glue) matrix has: form the oil phase material (oil phase) of external phase, aqueous oxidizing agent solution (water), the water-in-oil type emulsifier of formation disperse phase.Oil phase material comprises various waxes, the liquid petroleum product that from oil, extracts, and can be paraffin, explosive Wax special, Microcrystalline Wax, can be machine oil, diesel oil, white oil, heavy oil; Water-phase material mainly is an an ammonium nitrate, can add SODIUMNITRATE, nitrocalcite, sodium perchlorate, borax, sodium lauryl sulphate, sodium laurylsulfonate; Water-in-oil type emulsifier can be that pure monoleate, polyisobutenyl amine (I) type emulsifying agent are ploughed in the dehydration mountain, can be above-mentioned two kinds of compound emulsifying agents that emulsifying agent is compounded to form, and also can add soybean lecithin.
In emulsification (glue) substrate formula, water accounts for that total mass 91.0%-95.2%, oil phase account for total mass 4.0%-7.0%, emulsifying agent accounts for total mass 0.8%-3.0%.
The on-site mixed explosive mode of operation is the direction of national industrial explosive material industry encourage growth; Its medium-long range dispensing pattern is widelyd popularize in recent years; This pattern adopts terrestrial station's centralized preparation emulsification (glue) matrix, transportation vehicle commander distance journey to carry emulsification (glue) matrix of emulsification (glue) matrix, on-the-spot sensitization powder charge, have that security is good, scale and benefit significantly, the production efficiency advantages of higher.
In order to ensure the transportation safety of emulsification (glue) matrix, national correlation department requires on-site mixed vehicle-mounted emulsifying base must meet " Dangerous Goods Transport explosives approval, subitem program and equipped the requirement " (GB14371) or the dangerous difference standard of itemizing of adopting by equation United Nations " Dangerous Goods Transport recommendation-test and manual of standards " the 8th campaign.This touchstone mainly detects the thermal safety of emulsification (glue) matrix; Examination criteria is relatively stricter; Sample must pass through heat stability test, gap test, the test of gram south and the test of improved vent-pipe; Emulsification (glue) matrix can put 5.1-oxygenant of specifications of dangerous goods under, and permits transporting with tank body.But conventional on-site mixed packing emulsification (glue) matrix all is difficult to through this standard detection.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of working method with good thermal security emulsification (glue) matrix is provided.
Scheme of the present invention is: in emulsification (glue) substrate formula, water accounts for that total mass 91.0%-95.2%, oil phase account for total mass 4.0%-7.0%, emulsifying agent accounts for total mass 0.8%-3.0%, and three component mixing and emulsifyings is characterized in that:
The urea that in the water component, adds water-phase material (containing clear water) total mass 0.2%-2.5% carries out heating for dissolving;
The methyl pentachlorostearate or chlorinated paraffin-70 or chlorinated paraffin-52 or the chlorinated paraffin-42 that in oil phase component, add oil phase material total mass 1.0%-9.0% are with the emulsifying agent heat fused;
Form emulsification (glue) matrix after adopting the shearing of materials such as water that above method prepares, oil phase, emulsifying agent through special-purpose emulsifying equipment, stirring, emulsification.
The invention has the advantages that: through in the water component of emulsification (glue) substrate formula, adding an ammonium nitrate decomposing inhibitor, in oil phase component, adding fire retardant; Thereby improve the thermal safety of emulsification (glue) matrix, make it to reach " approval of Dangerous Goods Transport explosives, subitem program and equipped the requirement " (GB14371) or the requirement of the dangerous difference standard of itemizing of United Nations's < Dangerous Goods Transport recommendation-test and manual of standards>the 8th campaign.
Embodiment:
The urea that aqueous phase adds can discharge ammonia when being heated, and can play inhibition and slow down effect the thermolysis of an ammonium nitrate in emulsification (glue) matrix, and then improve the thermostability of emulsification (glue) matrix; The clorafin that adds in the oil phase is lowered the temperature, is stopped combustion chemistry and reacts, cuts off the mechanisms of action such as thermal source through intercepting, oil phase material is had good flame-retardant effect.
Through in the water component of emulsification (glue) substrate formula, adding an ammonium nitrate decomposing inhibitor-urea, in oil phase component, adding fire retardant-methyl pentachlorostearate or clorafin; Blocked the redox decomposition reaction of emulsification (glue) matrix effectively; Make the differential calorimetric detect (DSC) decomposition peak temperature and improve nearly 70 ℃ than common on-site mixed emulsion [explosive decomposition peak temperature; Guaranteed the thermal safety of emulsification (glue) matrix, made it to reach " approval of Dangerous Goods Transport explosives, subitem program and equipped the requirement " (GB14371) or the requirement of the dangerous difference standard of itemizing of United Nations's " Dangerous Goods Transport recommendation-test and manual of standards " the 8th campaign.
