| titleOfInvention | A kind of carbon nanotube-based sound-absorbing mass flocculent carbon material and its preparation method and application |
| abstract | The invention discloses a method for preparing a carbon nanotube-based sound-absorbing mass flocculated carbon material, comprising the following steps: mixing and dissolving two or more metal salts in deionized water to form a solution A; deionized water, ethanol, N , N-dimethylformamide is mixed, configured into a mixed solvent, 1H-pyrazole-4-formic acid is dissolved, 2,5-dihydroxy-1,4-benzoquinone or fumaric acid is dissolved in the above mixed solvent , to form solution B; mix solution A and solution B, put them into a microwave chemical reactor for reaction, and the obtained solid powder is nano-porous particles; attach the nano-porous particles to carbon nanotubes, and heat them in a non-oxidizing atmosphere at high temperature Carbonized to obtain agglomerated carbon materials. The invention also provides the sound-absorbing mass flocculated carbon material prepared by the preparation method. It realizes the combination of porous sound absorption mechanism and resonance sound absorption mechanism, and has efficient sound absorption performance in different frequency bands of high frequency and low frequency. |
