Embodiment Construction

[0022] The morphology was characterized by a Quanta600 scanning electron microscope from Quantachrome, USA, and the infrared characterization was performed by a Tensor27 Fourier transform infrared spectrometer from Bruker, Germany.

[0023] Synthesis of Graphene-Schiff Base Nickel Composite

[0024] (1) Synthesis of Aminated Graphene:

[0025] Place the ultrasonically dispersed graphene oxide ethanol dispersion in a three-necked flask, and add an appropriate amount of γ-aminopropyltriethoxysilane KH550 or N-β-(aminoethyl)-γ-aminopropyltrimethoxy Base silane KH792 ethanol solution, reacted under reflux conditions for 2h, cooled to room temperature after the reaction, collected by centrifugation and washed with ethanol to obtain aminated graphene. Among them, KH550

[0026] Or the mass ratio of KH-792 to graphene oxide is 15;

[0027] (2) Synthesis of graphene-Schiff base ligands:

Abstract

The invention discloses a preparation method of a graphene-Schiff base nickel composite, the structural formula of which is shown in I or II. Its synthesis process comprises the following steps: (1) using a coupling agent to modify graphene oxide to obtain aminated graphene; (2) reacting aminated graphene with salicylaldehyde to synthesize graphene Schiff base ligands; (3) Graphene-Schiff base ligand reacted with nickel nitrate to prepare graphene-Schiff base nickel composite. The graphene-Schiff base nickel composite synthesized by the method can significantly improve the burning rate of the modified double-base propellant containing HMX, and is an efficient combustion catalyst for solid propellants.

Description

technical field [0001] The invention relates to a graphene-Schiff base nickel composite and a preparation method thereof. The graphene-Schiff base nickel can effectively improve the burning rate of a modified double-base solid propellant containing Octogen (HMX), and can Used as a burn rate catalyst for modified double-base propellants. Background technique [0002] Solid propellants are widely used in tactical missiles and rockets, and their comprehensive performance is directly related to the precision strike, high-energy damage and survivability of modern weaponry systems. By adding Octogen (HMX), RDX and Hexanitrohexaazaisowurtzitane (CL-20), the energy characteristics of the propellant can be effectively improved to meet the long-range requirements of modern tactical missiles and rocket weapons And the need for quick penetration. [0003] However, the increase of solid content will reduce the burning rate of the modified double-base propellant. By using the lead-coppe...
