STUDY ON PROPERTIES OF HIGH-NITROGEN SINGLE-BASE PROPELLANT PREPARED FROM A SOLVENT CONTAINING N-BUTYLACETATE

摘要

In order to improve the mechanical properties of single-base propellant with high nitrogen content, 3% by weight of n-butyl acetate was added as an auxiliary solvent to the alcohol ketone mixed solvent to plasticize the high-nitrogen nitrocellulose in the propellant preparation. The test results of mechanical properties and combustion performance showed that the addition of n-butyl acetate significantly improved the mechanical properties of high-nitrogen single-base propellant, but reduced some energy. Therefore, 3%wt of RDX was then added to compensate for this energy loss. The test results showed that the propellant finally obtained maintained its energy, and its impact strength at -40"C was increased by 10.29% compared with the original sample.
