Abstract

The present invention discloses a nucleocapsid energizing agent for propelling agent and a method for preparing same, the energizing agent is a nucleocapsid structure energizing agent that carbon is encapsulated on a metallic oxide surfaced. The preparing method includes steps as follows: selecting one or some raw materials: address sugar, diose or soluble polysaccharide to mix according with random weight rate for confecting water solution 50-1500g / L, adding the surfactant or dispersant into the water solution, then adding the metallic oxide powder, the metallic oxide weight is 1-60% of the raw material total weight, the surfactants or dispersants weight is 0-4.5% of the metallic oxide weight, ultrasounding or stirring to distribute evenly, heating in 100-260 DEG C during 1-72 hours; reducing the product temperature to a room temperature, washing, centrifuging, removing the water-soluble impurity again and again, then vacuum drying for obtaining the nucleocapsid energizing agent. The nucleocapsid energizing agent has better compatibility with other component of the propelling agent, and has simple preparing technique, low cost, green process and is easy to mass production.

Description

technical field

[0001] The invention relates to a core-shell catalyst for propellants and a preparation method thereof, which belongs to the technical field of inorganic chemistry and also belongs to the technical field of functional materials. Background technique

[0002] Metal oxides (such as vanadium oxide, lead oxide, etc.) are commonly used combustion catalysts in propellants [(1) Singn NB, Ojha A K, Thermochim. Acta 2002, 390, 67; (2) Survase D V, Gupta M, Asthana SN , Prog. Cryst. Growth Charact. Mater. 2002, 45, 161; (3) Charavarthy R, Price E W, Sigman R K, J. Propul. Power 1991, 3, 471.]. In order to improve the catalytic performance of the catalyst, an effective method is to prepare the catalyst as nanoparticles to increase the active specific surface area of ​​the catalyst, thereby improving the catalytic efficiency. However, because nanoparticles are prone to agglomeration and are not easy to mix uniformly with other components of the propellant, it is difficu...
