Definitions

  • the invention relates to a method for preparing "wa­ter in oil" emulsion type explosive compositions and to the compositions obtained therefore.
  • the compositions comprise an organic fuel as continuous phase, and as - discontinuous phase an aqueous solution containing oxi­dizing salts among other components.
  • the oil phase comprises acrylonitrile/butylacrylate or vinyl acetate/ethylene - copolymers or a mixture of the two, together with conven­tional fuels.
  • the continuous fuel -- phase is formed by a liquid polymer that can be cross-­linked to give a thermo-stable resin.
  • the object of the invention is a novel emulsion explo­sive composition having a greater stability than exis­ting explosive emulsions without the need for substantial­ly varying its rheological conditions or methods of ma­nufacture.
  • the novel emulsion explosive compositions have a hydrated polymer macrostructure which envelops the - - aqueous oxidizing phase and is located in the boundaries of the interface produced by the emulsifying agent sys­tem.
  • the production of this macrostructure is based on a novel method for forming the final explosive composition. The method consists in adding to the aqueous solution one or more low molecular-weight organic compounds (hereinaf­ter called monomers) capable of polymerizing by addition.
  • monomers low molecular-weight organic compounds
  • polymeri­zation occurs mainly at the interface and adjacent areas, resulting in an enveloping macrostructure, thick enough as to increase the stability of the emulsion without a substantial influence in its viscosity.
  • the stability of the macrostructure can be increased by using monomers having more than one double bond or suitable functional groups for chemical cross-linking.
  • the addition of monomers instead of polymers to the aqueous phase has other advantages due to the low mole­cular weight of the monomer compared with the polymer. Emulsions tend to form with smaller drop size, since the aqueous phase containing the monomer has a much lower - viscosity than it would have if the polymer itself were - added. The presence of the monomer actually facilitates the formation of smaller drops since it is soluble in wa­ter and in a large number of organic compounds and to so­me extent increases the compatibility of the aqueous and the oil phase, thus assisting in the formation of the - - emulsion.
  • the water-in-oil emulsion-type explosive compositions according to the invention can have a wide range of vis­cosity and can be used in bulk pumpeable form or cartrid­ged in rolls 25 mm. or more in diameter, so as to be sen­sitive to the multiplier and to the detonator in both -- cases.
  • the emulsion comprises a continuous phase containing one or various hydrocarbon fuels, and a discontinuous -- phase comprising a supersaturated solution of inorganic oxidizing salts and a polymer macrostructure produced by polymerization of the partial or totally water soluble - monomers added to the aqueous solution before forming the emulsion. This is formed by means of emulsifying agents.
  • the inorganic oxidizing salts used according to the invention are e.g. nitrates, chlorates and perchlorates of ammonium and alkali and alkaline earth metals.
  • the salts can be used alone or in mixtures of two or more.
  • the following are representative inorganic salts, ammo­nium nitrate, sodium nitrate, potassium nitrate, calcium nitrate, magnesium nitrate, ammonium perchlorate, sodium perchlorate, potassium perchlorate, magnesium perchlorate and others known in the art.
  • the proportion of the salts in the emulsion is between 30 and 90% by weight of the composition.
  • the amount of water in the discontinuous phase of the emulsion may be selected depending on the intended use of the emulsion and can vary between approximately 0 and 30% by weight of the total composition. Preferably the - proportion is between 10 and 20%.
  • one or more organic pro­ducts having at least one double bond, and therefore -- capable of polymerization by addition are added to the salts solution.
  • These products are partly or totally so­luble in water and form part of the group comprising -- acrylic aldehyde, acrylamide, acrylic acid, methacrylic acid, itaconic acid, acrylonitrile, allyl amine, allyl alcohol, maleic anhydride, crotonic acid, derivatives - and others of similar chemical nature.
  • the proportions of these products vary between 0.1 and 10% by weight of the total composition, preferably between 0.2 and 4%.
  • initia­tion is preferably made by chemical initiators which, when subjected to heat or electromagnetic radiation or chemical reaction, undergo homolytic fission into radi­cals having greater reactivity than the monomeric radi­cals.
  • reaction systems can be used for producing radicals:
  • Polymerization can be initiated in the aqueous phase or in the oil phase.
  • redox and persul­phate reactions are generally used.
  • ini­tiation in the continuous oil phase the usual method is thermal or photolytic, preferably thermal decomposition of the chemical initiators.
  • the emulsion must form before polymerization has - - appreciably progressed.
  • the initiator can be added without any restriction at any time after the emulsion forms. This method of - - initiation enables polymerization to be restricted in - - simple manner to the interface. If the initiator is added to the aqueous phase, the concentration of monomer and initiator must be such that the emulsion forms before the polymerization process has appreciably advanced. By sui­table selection of the concentration of monomer, concen­tration of initiator, temperature and concentration of catalyst, any person skilled in the art can ensure that polymerization occurs substantially in a reasonably - - short interval of time after forming the emulsion.
  • the polymer macrostructure formed during polymeriza­tion gives great mechanical stability to the drop, inhi­biting the growth of inorganic crystals and thus increa­sing the life of the emulsion.
  • the macrostructure is located in the interface and the boundaries of the drops, its presence does not affect the rheological properties of the emulsion. For this reason, special interest - - attaches to those emulsions which need to pour out - - freely, i.e. have low viscosity, and/or are produced by techniques requiring low shearing forces.
  • addition of a monomer to the aqueous phase in order to polymerize it after the emulsion has been formed has a further advantage as com­pared with initial addition of polymers to the aqueous phase.
  • the re­placement of the polymer by a monomer before the emul­sion forms increases oil phase-aqueous phase viscosity ration, thus reducing the size of the drops of emulsion for a given shearing force. This increases the stabili­ty and sensitivity of the emulsion by increasing the contact surface between the oxidizing agent and fuel.
  • the emulsifying agent can be any of the kinds normally used in this class of emul­sions and can be used alone or in combination.
  • the emul­sifying agents can include e.g. sorbitan fatty-acid es­ters such as sorbitan sesquioleate, sorbitan monooleate, sorbitan monopalmitate, sorbitan monostearate, sorbitan triolate and sorbitan tristearate.
  • the emulsifier has double bonds in the molecule, it can sometimes form part of the macrostructure occur­ring during polymerization in some extent. Acceptable emulsification is usually obtained when the emulsifying agent amount is from 0.1 to 6%, preferably 0.2 to 4% and particularly preferably 0.5 to 3% by weight of the total explosive composition.
  • the conti­nuous organic hydrophobix phase of the "water in oil” emulsion normally comprises a hydrocarbon or carbonaceous fuel of mineral, animal or vegetable origin and liquid or solid at ambient temperature (in that case it should be liquid under the conditions for forming the emulsion).
  • the suitable organic compounds include aromatic and aliphatic saturated and unsaturated hydrocarbons and de­rivatives thereof and mixtures of any of them.
  • the pre­ferred compounds include mineral oil, diesel oil, para­ffin oil and wax, petroleum distillates, benzene, tolue­ne, xylene, epoxy soya oil, dinitrotoluene and mixtures thereof.
  • the rheological properties of the system can be controlled by adding waxes to the continuous organic -- phase.
  • the total continuous organic phase - corresponds to values between 1 and 20%, preferably - - between 2 and 10% by weight of the total explosive com­position.
  • compositions according to the invention can also include auxiliary or additional fuels.
  • auxiliary or additional fuels include - those which can be added to the aqueous phase, e.g. glu­cose, sucrose, fructose, maltose, molasses, glycols, formamide, urea, hexamethylene tetramide, methylamine nitrate, hexamethylene tetramine nitrate and other or­ganic nitrates.
  • Additional fuels include solid materials in particle form such as carbon, graphite, sulphur, alu­minium, magnesium and perchlorates,
  • the proportions of additional fuel can vary, depending on the desired cha­racteristics of the final explosive emulsion, but are usually between 0 and 20%, preferably between 0.5 and 10% by weight of the total explosive composition.
  • the explosive composition also contains a discontinuous gaseous component in order to increase its sensitivity and simultaneously reduce its density to values preferably between 0.7 and 1.4 g/cc.
  • Bubbles of air or gas can be incorporated in - the explosive composition by mixing hollow spheres - such as glass microspheres, resin microspheres or po­rous particles such as perlite or by mechanical agita­tion or injection or bubbling of gas through the com­position, or by chemical production of gas "in situ” by adding products such as hydrogen peroxide, sodium nitrite, sodium carbonate, N,N -dinitrous pentamethy­lene tetramine, nitrous acid or salts thereof which decompose in acid solutions, and organic foaming - - agents such as dinitrous components and diisocyanates.
  • the gaseous component is normally added to the emul­sion when cool and forms part of the emulsion in a pro­portion which varies between 0.01 and 60% by volume of the final explosive composition.
  • the explosive compositions according to the inven­tion can be used either in bulk form or in 25 mm car­tridges or more in diameter, depending on the viscosi­ty and the suitable added components.
