Preparation of Nanocellulose and Its Application in Nitrocellulose-based Gun Propellant

doi:10.3969/j.issn.1000-1093.2021.05.007

Abstract

Abstract: Nanocelluloses were prepared via a process of dissolution in phosphoric acid followed by regeneration in water. To facilitate the dissolution, the cellulose was pre-treated with aqueous urea solution. The composition, structure, and morphology of the materials in different preparation stages were studied by infrared spectroscopy (FTIR), X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. The nanocelluloses were added into the nitrocellulose-based gun propellant as the reinforcement, and the physicochemical properties, low temperature drop hammer crushing and impact strength were tested. The results show that the physicochemical properties of the propellant are not changed after nanocelluloses with mass fraction of 1.68% are added. However, the low temperature drop hammer crushing ratio is reduced from 70% to 20%, and the low temperature impact strength is increased by 30%.

Key words: nanocellulose, gunpropellant, nitrocellulose, impactproperty
