Definitions

• This invention relates to water-containing, nitric esterfree ammonium nitrate explosives. More particularly, this invention relates to water-containing, nitric ester-free ammonium nitrate explosives of increased sensitivity.
• alkali metal nitrates e.g. sodium potassium, lithium-nitrate and/or alkaline earth metal nitrates e.g. calcium, strontium, barium-nitrate,
• the brisant explosives may not be nitric esters because of the easy hydrolyzability of the latter:
• Aromatic nitro compounds such as, trinitrotoluene, trinitroanisole, trinitrobenzene, trinitrocresol, trinitrophentole, trinitronaphthaline, trinitromethylaniline, picric acid, trinitrorosorcinol, trinitrophloroglucine, hexanitrodiphenyl, hexanitrodiphenylamine, hexanitrodiphenyl oxide, hexanitrodiphenyl sulfide, hexanitrophenylsulfone, hexanitrodiphenylsulfoxide, hexanitroazobenzene and tetranitromethylaniline (tetryl), Nitramines, such as, ethylenedinitramine, hexogen (cyclotrimethylenetrinitramine), octogen and tetranitromethylaniline (tetryl), and the Nitrosamines, such as, cyclotrimethylene'trinitrosamine.
• tertiary amines are the following: tn'methylamine, triethylamine, triethanolamine, N-nbutyldlethanolamine, N-methyldiethanolamine, di-(2-hydroxypropyl)-ethanolamine, di-(Z-hydroxybutyl)-ethanolamine, triisopropanolamine, N-methylmorpholine, N- methylpyridine, N-methylpiperdine, N-methylpyrroline, N-methylpyrrolidine, N-fi-hydroxyethylmorpholine, and 1,2-dimorpholylethane.
• the tertiary amines can also be advantageously in the form of their nitrates as a component of the explosives in accordance with the invention.
• the nitrates of ammonia and of the alkali and alkalineearth metals, the perchlorates of ammonia and of the alkali metals, and the brisant explosives are used in the grain size which is conventionally employed in the formation of this type of explosives by the explosives industry namely in a grain-size smaller than 1 mm. in diameter (18 mesh), preferably 0.5-0.05 mm. (35-300 mesh).
• guar meal agar-agar
• water-soluble cellulose ethers e.g. methyl-carboxymethylcellulose (tylose types)
• water-soluble polymers on the basis of vinyl alcohol, 1,2-vinylenediol, methylolated acrylic amide, and the like.
• ionogenic and non-ionogenic emulsifiers which are conventionally employed in the explosives industry can be used as emulsifiers in the compositions in accordance with the invention in the percentages as stated above.
• the water-containing, nitric ester-free ammonium nitrate explosives of. the invention are characterized, as stated previously, by an increased sensitivity.
• the sensitivity of the slurries as herein taught is so great that they can even be ignited -by a No. 9 copper blasting cap.
• An additional advantage of the explosive slurries of the invention consists in that they are considerably more fluid with higher power than the corresponding waterammonium-nitrate-TNT types.
• EXAMPLE 1a.EXPLOSIVE ACCORDING TO THE INVENTION Composition 0.36 part by wt. of a water-soluble cellulose ether commercially obtainable under the name Tylose MH 50,
• Tonogenic emulsifiers are, e.g., fatty amine salt, fatty acid salt; non-inogenic emulsifiers are, e.g., ethoxylated fatty amines, ethoxylated phenols or naphthols.
• EXAMPLE 1b (For comparison with la) Composition 0.36 part by wt. of a water-soluble cellulose ether commercially obtainable under the name Tylose MH 50,
• EXAMPLE 2 Composition 0.39 part by wt. of a water-soluble cellulose ether commercially obtainable under the name Tylose MH 50,
• a water-containing, nitric ester-free ammonium nitrate explosive of increased sensitivity comprising:
• An explosive according to claim 1 ' Wherein there is additionally present 0.2-1 wt. percent of at least one member selected from the group consisting of swelling agents and emulsifiers.
• solid brisant explosive is a member selected from the group consisting of aromatic nitro compounds, nitramines and nitrosamines.
• tertiary amine is a member selected from the group consisting of: trimethylamine, triethylamine, triethanolamine, N-n-butyldiethanolamine, N-methyldiethanolamine, di-(2- hydroxypropyl) -ethanolamine, di- Z-hydroxybutyl -ethanolamine, triisopropanolamine, N-methylmorpholine, N- methylpyridine, N-methylpiperidine, N-methylpyrroline, N-methylpyrrolidine, N fi hydroxyethylmorpholine and 1,2-dimorpholylethane.
• said swelling agent is a member selected from the group consisting of guar meal, agar-agar, water-soluble cellulose ethers, water-soluble polymers on the basis of vinyl alcohol, 1,2-vinylene diol and methylolated acrylic amide.
