Method for preparing ceramic hollow microspheres at low cost
The invention discloses a low-cost method for preparing ceramic hollow microspheres, which comprises the following steps: weighing ceramic powder and a water solvent, adding additives into the water solvent to prepare a premixed solution, and the additives comprise a dispersing agent, a monomer, a cross-linking agent, a green body reinforcing agent and a foaming agent; ceramic powder and the premixed liquid are subjected to ball milling, and slurry with the solid content being 75-85% is prepared; adding an initiator and a catalyst, and uniformly mixing; preparing a super-hydrophobic track; the method comprises the following steps: obliquely placing tracks, arranging equipment with titration needle cylinders at the top ends of the tracks, enabling the single titration needle cylinders to be positioned above the independent tracks, attaching a heating tape to the lower part of an inclined surface, heating the inclined surface to 120-180 DEG C, injecting ceramic slurry into the titration needle cylinders, controlling the size of liquid drops to be 0.1-1.3 mm by the titration needle cylinders through the air inlet pressure of compressed air and the size of needle holes, and carrying out vacuum drying to obtain the ceramic slurry. The liquid drops drop onto the track coated with the super-hydrophobic film from the top end of the inclined plane, roll downwards and are heated and cured into ceramic microsphere blanks; and drying, degreasing and sintering the molded ceramic microsphere blank to obtain the finished product ceramic hollow microsphere.
本发明公开一种低成本制备陶瓷空心微球的方法,称取陶瓷粉体和水溶剂,在水溶剂中加入添加剂配置预混液,添加剂包括分散剂、单体、交联剂、坯体增强剂、发泡剂;将陶瓷粉体与预混液球磨制备固含量为75~85%的浆料;并加入引发剂和催化剂混合均匀;制备超疏水轨道;将轨道倾斜放置,将带有滴定针筒的设备置于轨道顶端,且单根滴定针筒位于各自独立的轨道上方,斜面下方用加热带贴附,将斜面加热至120~180℃,将陶瓷浆料注入滴定针筒,滴定针筒通过压缩空气的进气压力以及针孔尺寸控制液滴尺寸为0.1~1.3mm,液滴由斜面顶端滴落于施涂了超疏水薄膜后的轨道上,向下滚动并被加热固化成陶瓷微球球坯;将成型后的陶瓷微球球坯经干燥、脱脂、烧结后制得成品陶瓷空心微球。
