In order to improve the safety of the propellant production process, the electrostatic generation mechanism and control measures in the propellant production process are studied. Through the analysis of the main processes that are easy to generate static electricity in the of propellant, according to the mechanism of electrostatic generated in the production process of propellant, the measures to control the generation of the electrostatic generation during the production process of propellant are proposed from the aspects of contact charging, friction charging and heating charging,and the test is verified. The results show that the main measures to control the electrostatic generation are to change the work function of the device surface, increase the conductivity and environment humidity, reduce the migration of charge and balance the charge.
