Embodiment Construction

[0029]Embodiments of the present invention relate to nitrocellulose compositions that can be used in conjunction with explosives and weapons systems. Although embodiments of the present invention can be used in a variety of artillery and small arms, as well as in the aerospace and construction industries, including, but not limited to caseless munitions, combustible cases, rocket motors, bag charges, mortar increments, modular artillery charge systems (“MACS”:), head charges, underwater charges and others. Embodiments of the composition could also be used for vehicular air bags and for seat-belt tighteners. One example is a nitrocellulose composition suitable for the manufacture of Mortar Increment Containers and other combustible materials. The MICs are generally produced in a number of sizes, to fit mortars having diameters of 60 mm, 81 mm and 120 mm that are used by the military.

[0030]Referring to FIG. 1, mortar increment container 10 is an arcuate container having two halves 12,...

Abstract

A nitrocellulose composition comprises an admixture comprising: from about 75 weight percent to about 85 weight percent nitrocellulose; and from about 15 weight percent to about 25 weight percent camphor, based upon the weight of the admixture; and from about 1 weight percent to about 5 weight percent of a stabilizer (based on the total weight of the composition), wherein the stabilizer is chosen from the group consisting of N,N-Diethyl-N,N′-diphenylurea, N,N′-Dimethyl-N,N′-diphenylurea, 1,1-Diphenylurea, N-methyl-N,N′-diphenylurea, 1-Ethyl-3,3′-diphenylurea, Diphenylamine, 2-Nitro-diphenylamine, 4-Nitro-diphenylamine; Triphenylamine; p-Nitro-N-methylaniline, p-Nitro-ethylaniline, soybean oil, castor oil, sodium silicate, lactic acid amide, and benzonate; and from about 1 weight percent to about 5 weight percent of azodicarbonic acid diamide, based on the total weight of the composition. The composition is heated at a temperature sufficient to cause it to polymerize, after which it is formed into sheets, from which components for munitions, such as artillery, small arms, modular artillery charge systems and mortar increments are formed. The components of the mortar increments are joined together, and after being filled with a propellant composition, one or more mortar increments is attached to a mortar shell.

Description

FIELD OF THE INVENTION [0001]Embodiments of the present invention are nitrocellulose compositions. These compositions can be used in a variety of artillery and small arms such as but not limited to caseless munitions, combustible cases, rocket motors, bag charges, mortar increments, head charges, underwater charges and others. In one embodiment, the nitrocellulose composition can be used to prepare empty propellant containers, known as Mortar Increment Containers (“MICs”). The MICs are cellulose nitrate based containers into which a propellant mixture is placed, and one or more filled MICs are attached to a mortar shell.BACKGROUND OF THE INVENTION [0002]Nitrocellulose (also referred to as cellulose nitrate or gun cotton) has been used in the manufacture of various products, ranging from products as diverse as nail enamel, filters for laboratory or commercial use for sterilizing or purifying liquids, photographic film, to explosives such as gun powder, propellants, and / or containers ...
