United States Patent Int. Cl. C06b 1/04 US. Cl. 149-56 8 Claims ABSTRACT OF THE DISCLOSURE Water-containing, nitric ester-free ammonium nitrate explosives of increased sensitivity composed of water, ammonium nitrate, a brisant explosive, tertiary amines or nitrates thereof, ammonium and/or alkali metal perchlorates, and a swelling agent and/or emulsifier.
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.
Water-containing, nitric ester-free ammonium nitrate explosives prepared on the basis of water, ammonium nitrate and trinitrotoluene are known. Explosives of this type, of a quasi-liquid consistency, are generally known as slurries. The known slurries of this type, however, have the disadvantage of low sensitivity, and can be brought to detonation only by means of relatively large initiating charges.
It is an object of this invention to provide explosives of the aforesaid type which are not associated with the disadvantages as above noted.
It is a further object of this invention to provide water-containing, nitric ester-free ammonium nitrate explosives of increased sensitivity.
These are still further objects will appear from the description of this invention as hereinafter disclosed.
The above objects can be accomplished in accordance with the invention by providing an explosive having the following composition:
-15 wt. percent water,
30-80 wt. percent ammonium nitrate, of which up to 10 wt. percent can be replaced by alkali metal nitrates e.g. sodium potassium, lithium-nitrate and/or alkaline earth metal nitrates e.g. calcium, strontium, barium-nitrate,
2-15 wt. percent of a brisant explosive having a detonation rate greater than 5000 m./sec.,
2-10 wt. percent tertiary amines or nitrates thereof,
5-25 wt. percent perchlorates of ammonium and/ or alkali metals, and
0.2-1 wt. percent of swelling agent and/or emulsifier.
The following are illustrat-ive brisant explosives having a detonation rate greater than 5000 m./sec., which are suitable for use in accordance with the invention. 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.
The instances of suitable 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).
The following, for example, are illustrative of the swelling agents which can be used in the manufacture of the explosives of the invention: 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.
The 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.
The following examples are given to illustrate the in vention, it being understood that these examples are not intended to be limitative with respect to the specific details thereof:
