Preparation method of polymer-based composite energetic material-coated modified nano metal particles

Abstract

The invention discloses a preparation method of polymer-based composite energetic material-coated modified nano metal particles, and the preparation method is used for solving the technical problem ofpoor practicability of the existing preparation method of coated nano metal powder. According to the technical scheme, nano metal powder is added into a precursor polymer solution by adopting an electrostatic spraying method, and then an energetic oxidant AP or CL-20 is embedded in the solution to form the composite micro-nano material with zero oxygen balance. The composite nano metal powder obtained by the electrostatic spraying method has uniform particle size distribution and high particle sphericity and is not agglomerated easily. The used polymer material is NC or polyvinylidene fluoride (PVDF), and the NC and PVDF are both high molecular polymers which have excellent mechanical property and are easily dissolved in organic solvents, so that the metal powder can be effectively and uniformly dispersed in the precursor solution. In addition, the energetic oxidant is added into the system, so that the technical problems that existing nano metal powder is oxidized easily, and energyand ignition performance of nano powder coated by a conventional method are low can be solved through the electrostatic spraying method, and practicability is good.

AI Technical Summary

Benefits of technology

This technology allows for better dispersion of nanoparticles into liquid matrices without being affected from their chemical structure during processing steps like synthesis. It involves adding an ionizable substance called AIBN (ammonium peroxide) onto a special type of plastic resin made up mostly of polyvinyl chloride). By applying voltage between two parallel plate conductors placed close enough together under certain conditions, electrons flow through them causing it to break down molecules containing nitrogen atoms. These particles then become charged positively when exposed to strong electric fields within specific ranges of electrical potential difference across these terminals.

Problems solved by technology

This patented technical problem addressed in this patents relates to improves the properties of nanosheptium carbonyl ammonia complex composites made from neonium powders. These new compositions exhibit improved thermal stability compared to existing products while also having better control over their burning behavior than previous designs. Additionally, these novel composites may contain various substances like iron hydroxylaminoferrite, magnetically active ceramics, tantalum sponge, etc., making them easier to handle when mixed together without causing damage on sensitive areas within the composition.
