AlN/C复合泡沫材料及其制备方法
摘要：
本发明公开了一种AIN/C复合泡沫材料，该材料按质量百分比，由30％～60％的石墨碳和70％～40％的AIN组成，总质量为100％，所述的石墨碳采用空心石墨化碳微球结构，其直径为亚毫米到毫米量级，所述的AIN为六方结构，并填充在所述空心石墨化碳微球的空隙中。本发明还公开了上述材料的制备方法，按以下步骤实施：按质量百分比称取30％～60％的空心树脂微球和70％～40％的AIN粉末混合后加入酒精充分震动，随后将包裹有AIN薄膜的树脂微球过滤、干燥后注入模具中挤压成型，得到AIN/树脂微球复合泡沫坯料；对AIN/树脂微球复合泡沫坯料在200℃～1200℃之间升温进行碳化，并继续升温到1200℃~2700℃进行石墨化，并同步完成AIN的结晶，即得AIN/C复合泡沫材料。
摘要（英）：

The present invention discloses an AIN/C composite foam material, comprising the following raw materials by mass percentage: 30%-60% of graphite carbon and 70%-40% of AIN; the graphite carbon adopts a hollow graphitized carbon microsphere structure and the diameter of which is a sub-millimeter to millimeter grade; the AIN is a hexagonal structure and filled in the clearance of the hollow graphitized carbon microsphere. The invention also discloses a method for preparing the material and comprises the following steps of mixing 30%-60% of the hollow resin microsphere and 70-40% of AIN powder by mass percentage, subsequently adding alcohol into the mixture and fully vibrating, subsequently filtering, drying and injecting the resin microsphere containing the AIN film into a die for extrusion and forming, thus obtaining the AIN/resin microsphere composite foam blank; heating and carbonizing the AIN/resin microsphere composite foam blank at the temperature of 200 DEG C-1200 DEG C, continuing to heat the mixture to the temperature of 1200 DEG C-2700 DEG C to carry out graphitizing, and synchronously completing the crystallization of the AIN, thus obtaining the AIN/C composite foam material.
