Abstract

The invention discloses a preparation method of an energetic material with controllable interface infiltration performance. The preparation method includes the steps that firstly, an energetic material with hydrophilicity is prepared; secondly, an energetic material wrapping specific nanometer particles is prepared; thirdly, washing and drying are conducted; fourthly, soaking with an alkyl siloxane solution is conducted; and fifthly, washing and drying are conducted, so that the energetic material with the controllable interface infiltration performance is obtained. The preparation method has the beneficial effects that expensive equipment and severe experiment conditions do not need to be used, and the production cost is reduced; the characteristics of convenience and rapidness are achieved, and good infiltration performance controllability is achieved; the energetic material which is prepared through the preparation method and has the controllable surface and interface infiltration performance is used for the field of PBX, the infiltration performance can be changed at any time according to changes of a bonding system, and a good solid-liquid complete infiltrating and wrapping effect is achieved; and water-insoluble energetic materials such as HMX, RDX and TATB can be used as modification matrixes, and the wide application range is achieved.

Description

Technical field [0001] The invention relates to a preparation method of an energetic material, in particular to a preparation method of an energetic material with controllable interface wettability, and belongs to the technical field of material preparation. Background technique [0002] Pouring polymer bonded explosives (PBX) with high-energy explosives such as Oktogen (HMX) and RDX (RDX) as the main charge contains a variety of components with different surface properties, solid-liquid, solid -The bonding force of the solid-phase interface is a major problem that plagues designers. Due to the problem of surface and interface wettability, it is usually necessary to add additives such as bonding agent during the use of the main explosive to make the explosive and other components in the PBX have better wettability and compatibility, and it is easy to form a uniformly coated mixture Explosive system is also one of the effective ways to improve the mechanical properties of PBX mol...
