    • 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.
    • 硝化纤维素组合物包含混合物,其包含:约75重量%至约85重量%的硝化纤维素; 和约15重量%至约25重量%的樟脑,基于该混合物的重量; 和约1重量%至约5重量%的稳定剂(基于组合物的总重量),其中稳定剂选自N,N-二乙基-N,N'-二苯基脲,N, N'-二甲基-N,N'-二苯基脲,1,1-二苯基脲,N-甲基-N,N'-二苯基脲,1-乙基-3,3'-二苯基脲,二苯胺,2-硝基 - 二苯胺, 硝基二苯胺; 三苯胺; 对硝基-N-甲基苯胺,对硝基乙基苯胺,大豆油,蓖麻油,硅酸钠,乳酸酰胺和苯甲酸酯; 和约1重量%至约5重量%的偶氮二甲酸二酰胺,基于组合物的总重量。 将组合物在足以使其聚合的温度下加热,之后将其形成为片材,由此形成用于弹药的组分,例如火炮,小武器,模块化火炮装料系统和砂浆增量。 砂浆增量的组分连接在一起,并且在填充推进剂组合物之后,将一个或多个砂浆增量附着在砂浆壳上。

    • The present invention is directed to a propellant composition made from a lacquer, the lacquer comprising: (a) from about 15 to about 70 wt % of an organic solvent; (b) from about 0.1 to about 2.5 wt % of a stabilizer; (c) optionally, from about 0% to about 40 wt % of an energetic plasticizer; (d) optionally, from about 0 to about 10 wt % of a nonenergetic plasticizer; (e) optionally, from about 0 to about 10 wt % water; (f) optionally, from about 0 to about 15 wt % of additional additives; and balance being nitrocellulose; all weight percents based on the total weight of the composition, and wherein the lacquer has a viscosity of less than 10 million centipoise when processed. The present invention is also directed to an efficient and safe method of making perforated propellant grains using the above lacquer composition, as well as propellant grains having ellipsoidal cross sections or outwardly extending ridges.
    • 本发明涉及由漆制成的推进剂组合物,所述漆包含:(a)约15至约70重量%的有机溶剂; (b)约0.1至约2.5重量%的稳定剂; (c)任选地,约0%至约40%重量的能量增塑剂; (d)任选的约0至约10重量%的非易失性增塑剂; (e)任选地,约0至约10重量%的水; (f)任选地,约0至约15重量%的其它添加剂; 余量为硝酸纤维素; 基于组合物的总重量的所有重量百分数,并且其中所述漆在加工时具有小于1000万厘泊的粘度。 本发明还涉及使用上述漆组合物制造穿孔推进剂颗粒的有效和安全的方法,以及具有椭圆形横截面或向外延伸的脊的推进剂颗粒。
