Problems solved by technology

[0003] However, during the use of aluminum powder, sometimes it involves the use environment containing water. Since aluminum powder has high surface activity, it is easily oxidized and deactivated when it contacts with water, resulting in a significant drop in activity, making it used as a Significantly lower performance when using energy materials

Embodiment 1

[0034] (1) Weigh aluminum powder and protective agent respectively (paraffin wax is used as the protective agent in this embodiment), and the mass ratio of aluminum powder and protective agent is 98:2, and is for later use.

[0035] (2) The protective agent is added to the second solution (alkane is used for the second solution) at 70-80° C. under stirring conditions, and the protective agent is fully dissolved in the second solution to obtain the second intermediate.

[0036] (3) The aluminum powder and the first solution (the first solution adopts alkane) are mixed and stirred evenly at 70-80° C. to obtain the first intermediate, and the first intermediate is continuously stirred.

[0037] (4) The second intermediate is added dropwise to the first intermediate at 70-80° C. under stirring conditions. After the dropwise addition of the second intermediate is completed, the solution is continued to be stirred for 2-6 h until the protective agent and the aluminum powder are comp...

Embodiment 2

[0041] (1) Weigh aluminum powder and protective agent respectively (in this example, the protective agent adopts a titanate coupling agent), and the mass ratio of aluminum powder and protective agent is 99:1, for use.

[0042] (2) The protective agent is added to the second solution (the second solution adopts ethyl acetate) at 60-70° C. under stirring conditions, and the protective agent is fully dissolved in the second solution to obtain the second intermediate.

[0043] (3) Mix and stir the aluminum powder and the first solution (the first solution adopts alkane) at 60-70° C. to obtain the first intermediate, and the first intermediate is continuously stirred.

[0044] (4) The second intermediate is added dropwise to the first intermediate at 70-80° C. under stirring conditions. After the completion of the dropwise addition of the second intermediate, the solution was continued to be stirred for 5 hours until the protective agent and the aluminum powder were completely coat...

Abstract

The invention discloses an aluminum powder protection method with simple preparation method, stable product quality and reliable product quality. Add to the second solution at 80°C under stirring conditions, and fully dissolve the protective agent in the second solution to obtain the second intermediate; (3) Mix the aluminum powder and the first solution at 40-80°C and stir evenly, The first intermediate is obtained, and the first intermediate is continuously stirred; (4) at 40-80° C. under stirring conditions, the second intermediate is added dropwise to the first intermediate; the dropwise addition of the second intermediate is completed Then, continue to stir the solution until the protective agent and the aluminum powder are completely coated to obtain the third intermediate; (5) Dynamically dry the third intermediate at 40-90° C. to obtain coated particles. The present application can achieve effective protection of the aluminum powder, and can better control the ratio of the protective agent to the aluminum powder.

Description

technical field [0001] The invention relates to the field of materials, in particular to an aluminum powder protection method. Background technique [0002] Aluminum powder has a low melting point, moderate metal activity, good storage stability, low oxygen consumption, high density, rich raw materials and low cost. It is an ideal energetic metal fuel. At present, aluminum powder has been widely used in high-energy explosives, which can improve the detonation performance and make the formula have the characteristics of high detonation heat and high power. [0003] However, in the process of using aluminum powder, sometimes it involves the use environment of water. Because aluminum powder has high surface activity, it is easily oxidized and deactivated when it comes into contact with water, resulting in a significant decrease in activity, making it used for containing The performance of the energy material is greatly reduced. To this end, it is necessary to coat a layer of ...
