Preparation and Performances of an Intrinsically Safe Double-Base Propellant by One-Step Nitration
摘要
Abstract
In the traditional preparation process of double-base propellant(NC/NG),there exists a significant safety hazard due to the accumulation of free nitroglycerin(NG).An innovative one-step synthesis process was adopted,which achieves simultaneous nitration of cellulose and glycerol and in-situ absorption of the products in a low-temperature mixed acid system,and a novel double-base propellant was prepared.Experimental results show that this process eliminates the generation and accumulation of free NG from the source.A pure and homogeneous NC/NG composite system was formed,and it is consistent with the chemical structure of typical double-base propellants.Performance characterization confirms that the product exhibits superior batch-to-batch stability while maintaining comparable thermal decomposition characteristics and energy levels to typical double-base propellants.A dense,defect-free microstructure was formed by si-multaneous nitration-in-situ absorption,effectively eliminating hot spots that can induce accidents,and the safety performa-ces of the product could be improved.关键词
