| titleOfInvention | A kind of preparation method of high stability and high compatibility modified aluminum-lithium alloy powder |
| abstract | The invention provides a preparation method of modified aluminum-lithium alloy powder with high stability and high compatibility. The aluminum-lithium alloy powder is ultrasonically dispersed in an organic solvent to obtain an aluminum-lithium alloy powder dispersion; Alkylmethoxysilane and small molecule methoxysilane were added, and the reaction was stirred at room temperature for 30-180 min, so that the two were coupled and reacted on the surface of the aluminum-lithium alloy powder to form a dense copolymer coating; Filtration, washing, and vacuum drying to obtain modified aluminum-lithium alloy powder. In the present invention, a dense coupling coating layer is formed by alkylmethoxysilane and small molecular methoxysilane, which not only improves the stability of the aluminum-lithium alloy powder, but also improves the combustion performance after being stored in a high temperature and high humidity environment. It also improves the compatibility of aluminum-lithium alloy powder in composite solid propellant, provides technical support for the practical application of aluminum-lithium alloy powder in composite solid propellant and other energetic materials, and has the advantages of simple process and easy scale. Preparation and low cost advantages. |
