Problems solved by technology

In 2012, Zhang Yan and others filled nano-CuO particles into carbon nanotubes to obtain a uniformly filled nanocomposite (Zhang Yan, Xue Jian. Preparation and characterization of nano-CuO particles filled multi-walled carbon nanotube composites[J ]. Applied Chemical Industry, 2012,41(03):476-479.), but no research has been done on the combustion catalytic performance of the composite material

Embodiment 1

[0026]Add 150 mg of multi-walled carbon nanotubes with a diameter of 4 to 6 nm into 15 mL of a mixed acid solution with a volume ratio of concentrated sulfuric acid and concentrated nitric acid of 3:1, and perform ultrasonic treatment for 4 h at a temperature of 30 ° C and a power of 300 W to obtain a black viscous Thick solution, add deionized water to this solution, stir it evenly with a glass rod, then let it settle at room temperature for 12 hours, you can see that there are obvious layers in the beaker, pour off the upper layer of transparent solution, add deionized water again, and so on After several times a black suspension was obtained. The black suspension was separated by suction filtration, and washed repeatedly with deionized water until the pH of the obtained black solid precipitate was neutral. After the black solid precipitate was transferred to a blast drying oven at 80°C for 12 hours, it was ground evenly. The oxidized carbon nanotubes with open ends were obt...

Abstract

The invention discloses a carbon nanotube filled copper metal complex nano composite burning rate catalyst, which is prepared by the following steps: performing ultrasonic treatment on multi-walled carbon nanotubes with different tube diameters through a mixed acid solution to obtain oxidized carbon nanotubes with openings at two ends, adding the oxidized carbon nanotubes into a saturated solution of Cu(NO3)2.3H2O, [Cu(TMEDA)2](NO3)2 (TMEDA=tetramethylethylenediamine), [Cu(MIM)4](DCA)2 (MIM=1-methylimidazole, and DCA=dicyandiamide anions), or [Cu(NMIM)4](DCA)2 (NMIM=2-nitro-1-methylimidazole, and DCA=dicyandiamide anions), carrying out ultrasonic treatment to fill the cavities of the oxidized carbon nanotubes with the copper metal complexes, thereby obtaining the nano composite burning rate catalyst with the carbon nanotubes filled with the copper metal complexes. The preparation method is simple, and the obtained nano-composite burning rate catalyst is good in catalytic effect and easy to prepare in an enlarged mode.

Description

technical field [0001] The invention belongs to the technical field of solid propellants, in particular to a carbon nanotube filled copper metal complex nanocomposite burning rate catalyst. Background technique [0002] Solid propellant is a commonly used rocket engine power source, and its combustion state will directly affect the performance of aerospace rockets. After long-term research, solid propellants have formed a development trend of high energy, high specific impulse, and low signal characteristics. Ammonium perchlorate (AP), a strong oxidant, is a common energetic material component in solid propellants, especially in double-base propellants and their modified propellants. Since ammonium perchlorate generally has a relatively large proportion, the combustion rate, thermal decomposition peak temperature and heat release of its decomposition process have a great influence on the combustion of solid propellants. Among the existing methods for improving the combustio...
