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.
本发明涉及一种由漆制成的推进剂组合物,该漆包括:(a) 约 15 至约 70 wt% 的有机溶剂;(b) 约 0.1 至约 2.5 wt%的稳定剂; (c) 可选地,约 0% 至约 40 wt%的高能
增塑剂; (d) 可选地,约 0 至约 10 wt%的非高能
增塑剂; (e) 可选地,约 0 至约 10 wt%的
水;(f) 可选地,约 0 至约 15 wt%的附加添加剂;余量为
硝化纤维素;所有重量百分数均基于组合物的总重量,其中,漆在加工时的粘度小于 1 千万厘泊。本发明还涉及一种使用上述漆组合物制造穿孔推进剂颗粒以及具有椭圆形横截面或向外延伸脊的推进剂颗粒的有效而安全的方法。
