Crosslinked double base propellant binders |
摘要 |
A crosslinked binder for crosslinked double base propellant is provided. The binder is prepared from nitrocellulose having a nitrogen content of 11 to 13.4% N and an intrinsic viscosity of 0.55 dl./gram to 2.0 dl./gram, a polymeric diol having a hydroxyl functionality of 1.9 to 2.1 and a polyfunctional isocyanate having an NCO functionality of at least three. The propellant prepared from the binder exhibits improved mechanical properties without detriment to ballistic performance.
