FIELD: chemistry.SUBSTANCE: oxidant in the form of ammonium nitrate is dissolved in a mixture of water and acetonitrile using a magnetic mixer at 55-65°C for not less than 30 minutes. A fuel-binder is dissolved in the obtained solution at the same temperature for not less than 60 minutes. The solvent is stripped for not less than 3 hours while stirring at temperature of 55-65°C and pressure of not more than 0.03 MPa. The fuel-binder used is methylpolyvinyl tetrazole which is plasticised with a nitramino-nitrotriazole plasticiser. Metallic fuel is mechanically placed in the obtained mixture of oxidant and fuel-binder, said metallic fuel being in the form of a mixture of micro- and nanopowder of aluminium, guanyl-urea salt of dinitramide and a curing agent in the form of di-N-oxide-1,3-dinitrile-2,4,6-triethylbenzene. The obtained mixture is evacuated, moulded and polymerised at room temperature to obtain a high-energy composite. Fine crystalline ammonium nitrate can be used with particle size of 2-10 mcm.EFFECT: high stability of physical-mechanical properties, rate of combustion, improved inflammability, low sensitivity to mechanical action and reduced dependency of the rate of combustion of the composite on pressure changes.2 tbl |
