High-temperature resistance performance of gun propellant modified by HPMC coating
Abstract
Abstract Aiming at the problem that gun propellants are prone to deflagration under high-temperature chamber pressure, this paper proposes a high-temperature resistant coating using hydroxypropyl methyl cellulose (HPMC) as the film-forming material, and zirconia (ZrO 2 ) and titanium dioxide (TiO 2 ) as functional fillers. The results show that the 5s explosion point is increased by 28.9 °C, and the high-temperature resistance time at 200 °C is increased by 27.233 s. The research method for preparing high-temperature resistant composite coatings proposed in this study can effectively improve the high-temperature resistance performance of gun propellants.
