Method for preparing mixed explosive by utilizing resonance mixing technology

Abstract

The invention discloses a method for preparing an mixed explosive by utilizing a resonance mixing technology. The method comprises the following steps: (1) adding a single-compound explosive and at least one of an adhesive, resin, an oxidant and powder in a container which is filled with a solvent, thus obtaining a mixed material; (2) fixing the container filled with the mixed material to a load bearing plane of a vibrating table; (3) regulating the working frequency, the vibration acceleration, the vibration amplification, the speed, the vibration mode and the vibration time of the vibratingtable, enabling the vibrating table, the materials and the container to reach a resonance state, stopping vibration after completely mixing the single-compound explosive with the powder, the adhesive,the resin and the oxidant, and evaporating the solvent in the step (1), thus obtaining the mixed explosive. The method disclosed by the invention has the advantages of high mixing efficiency, good uniformity, small risk stimulus amount and the like, and not only the functional requirement on mixing of energetic materials can be met, but also the safety requirement on the mixing of the energetic materials can be ensured.

Description

technical field [0001] The invention relates to the technical field of material mixing, in particular to a method for preparing mixed explosives using resonance mixing technology. Background technique [0002] High-performance energetic materials (explosives and propellants), as the power and power energy for long-range suppression, precision strikes and efficient damage in weapon systems, are an important material basis for efficient weapon damage and system security. Adequate material mixing is an essential process for the manufacture of energetic materials and weapon charge, and it is also a key process unit that affects the performance of weapons. The existing general-purpose material mixing equipment includes paddle agitator, twin-screw mixer and kneader. These three kinds of material mixing equipment have certain limitations when used in multi-component, high-viscosity, high-solid content compound energetic manufacturing and charging. limitations, there is an urgent n...

AI Technical Summary

Problems solved by technology

[0003] The existing mixing methods such as paddle agitator, twin-screw mixer, and kneader have some defects in process safety and process functionality, and it is difficult to meet their process requirements well.

For example: Twin-screw mixers and kneaders are commonly used material mixing equipment for high-solid content PBX granulation and pouring charges. Because PBX and propellant components include RDX (Hessogen) and HMX (Octogen) , CL-20, AP (ammonia perchlorate), aluminum powder and other high-energy materials, as well as a variety of small component additives. With the continuous increase of solid mass fraction, the limitations of the use of twin-screw and kneader gradually become prominent On the one hand, the mixing efficiency is low, which cannot fully ensure the uniform mixing of various small-component additives in the high-solid content system; The friction and collision of the process will significantly increase the risk of the process
