Abstract

The invention provides a low-temperature preparation method of a combustion rate regulator for a carbon-based zinc oxide composite propellant, which mainly comprises the following steps: exposing a carbon-based substrate in diethyl zinc vapor to adsorb vapor molecules on the surface of the carbon-based substrate; blowing away part of physically adsorbed diethyl zinc molecules on the surface of thesubstrate from the surface of the substrate by using inert gas; exposing the carbon-based substrate to steam of water, so that steam molecules of the water and adsorbed diethyl zinc molecules are subjected to a chemical reaction; using inert gas for blowing away byproducts and redundant steam molecules on the surface of the substrate from the surface. The invention discloses a combustion rate regulator. Compared with a traditional combustion speed regulator and a carbon-based combustion speed regulator prepared by adopting other methods, the combustion rate regulator of the invention is excellent in combustion speed regulation capability, capable of effectively reducing the AP decomposition temperature and optimizing the energy release structure, is mild in preparation temperature, high in automation degree, good in safety performance, capable of being directly used without aftertreatment, easy to realize batch production and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of powder material surface modification and preparation thereof, and in particular relates to a burning rate regulator for carbon-based zinc oxide composite propellant and a low-temperature preparation method thereof. Background technique [0002] The combustion performance of the propellant has an important influence on the ballistic performance of the rocket engine. The burning rate determines the working time and flight speed of the rocket engine, and the impact of the burning rate on the external conditions (temperature and pressure) directly affects the stability of the engine's working performance. Therefore, it is very important to control and adjust the combustion performance of rocket propellants to meet the performance requirements of various artillery, rocket engines and rocket weapons. Burning rate regulator is the most common method to adjust and improve the combustion performance of propellant...
