Anti-hydrolysis aluminum nitride granulation powder and preparation method thereof
The invention relates to the technical field of aluminum nitride powder preparation, in particular to hydrolysis-resistant aluminum nitride granulation powder and a preparation method thereof. The preparation method comprises the following steps: carrying out first ball-milling mixing on polyethylene glycol, yttrium oxide and an organic solvent to obtain a first mixture; aluminum nitride powder, a silane coupling agent and the first mixture are subjected to second ball milling mixing, and a second mixture is obtained; performing third ball-milling mixing on an adhesive and the second mixture to obtain mixed slurry; screening the mixed slurry to obtain a filtered material; carrying out spray granulation on the filtered material to obtain spherical hydrolysis-resistant aluminum nitride granulation powder; the second ball-milling mixing time > the third ball-milling mixing time > the first ball-milling mixing time. According to the preparation method, soft agglomeration of the aluminum nitride powder can be depolymerized through ball-milling mixing modification, in addition, in the ball-milling mixing process, grinding balls can collide with the aluminum nitride powder to generate energy, so that a silane coupling agent is anchored on the surfaces of aluminum nitride powder particles, and the hydrolysis resistance of the aluminum nitride powder is improved.
本申请涉及氮化铝粉体制备技术领域，尤其涉及一种抗水解氮化铝造粒粉及其制备方法；所述制备方法包括：将聚乙二醇、氧化钇和有机溶剂进行第一球磨混合，得到第一混合物；将氮化铝粉、硅烷偶联剂和第一混合物进行第二球磨混合，得到第二混合物；将粘接剂和第二混合物进行第三球磨混合，得到混合浆料；将混合浆料筛选，得到过滤物；将过滤物喷雾造粒，得到球形抗水解氮化铝造粒粉；第二球磨混合的时间＞第三球磨混合的时间＞第一球磨混合的时间。该制备方法通过球磨混合改性能够对氮化铝粉的软团聚进行解聚，另外在球磨混合过程中研磨球会与氮化铝粉碰撞产生能量，以促使硅烷偶联剂锚固在氮化铝粉颗粒的表面，从而提高氮化铝粉的抗水解性能。
