Abstract

The invention discloses a method for improving the adhesive force of an electrophoretic deposition energetic film, and relates to the technical field of energetic materials, and the method comprises the following steps that (1) Al or Mg and a metal oxide are added into an organic solvent according to the mass ratio of 1: (1-4), and ultrasonic dispersion is conducted to obtain a suspension; (2) an organic material is added into the mixed solution, and ultrasonic treatment is conducted to obtain a solution; (3) the suspension in the step (1) is used as an electrophoretic deposition solution, a cathode and an anode are put in, electrifying is performed, and depositing is conducted on the surface of the cathode to obtain a thin film; and (4) the thin film is immersed into the solution obtained in the step (2), standing lasts for 5-30 seconds, and then vacuum drying is carried out. The method has the beneficial effects that the solution soaking method is adopted to improve the adhesive force of the electrophoretic deposition energetic film on the surface of the base material, the operation process is simple, the cost is low, and the film is good in stability and high in adhesive force.

Description

Technical field [0001] The present invention relates to the field of energy-sensible material, and more particularly to a method of improveing ​​electrophoretic deposition of film adhesion, improved film-containing film and application. Background technique [0002] The aluminum heat agent is used as one of the energy-containing material, and the active reaction substance consisting of reducing agents (Al, Mg, Si, B, etc.) and an oxidant (metal oxide or non-oxide) can be severely stimulated. The redox reaction has high thermal values, high heat insulation, and the reaction process still can spread in an oxygen environment, and is widely used in combustion agents, ignition drugs, high-energy explosives and solid rocket propellants. In recent years, with the development of aerobics, mechanical and electrical fireworks, aluminum thermosetting technology is increasingly concerned. [0003] As a thin film (or coating), electrophoretic deposition technique is made of rapid film formati...
