| titleOfInvention | Preparation method of silicon carbide and carbon nano tube composite wave-absorbing material |
| abstract | The invention provides a preparation method of a silicon carbide and carbon nano tube composite wave-absorbing material, comprising the following steps of: dispersing the silicon carbide into a nitrate solution and immersing to form a metal-silicon carbide composite with 5-15% of a metal component by weight; after the immersion, evaporating slurry to be dry and drying at a temperature in a range of 60-120 DEG C for 6-24 hours; calcining the dried product at a temperature in a range of 300-600 DEG C for 4-6 hours and adding a material which needs to be grinded after being cooled into a quartz tube; introducing methane into one end of the quartz tube and communicating the other end of the quartz tube with atmosphere; setting a temperature-rising speed to be 5-15 DEG C/min and setting a reaction air speed to be 300-3000 per hour; raising the temperature to 500-900 DEG C and reducing the temperature to a room temperature after keeping at constant temperature for 1-5 hours; and taking out the obtained material, namely the silicon carbide and carbon nano tube composite wave-absorbing material. The silicon carbide and carbon nano tube composite wave-absorbing material prepared by the preparation method has the advantages of high-temperature resistance, and capability of enhancing the wave-absorbing property and the stability of the material. |
