Composite preparation method of submillimeter zirconia ceramic microbeads
The invention discloses a composite preparation method of submillimeter zirconia ceramic microbeads, which belongs to the technical field of ceramic materials, and comprises the following steps: adding an initiator and a photocuring agent into a mixed solution of a propylene monomer, a crosslinking agent, a dispersing agent and yttria-stabilized zirconia to form zirconia slurry, injecting the zirconium oxide slurry into oil-bath liquid paraffin containing a catalyst, irradiating by adopting ultraviolet light to form zirconium oxide ceramic microbead green bodies, sintering the green bodies byadopting temperature programming, and carrying out self-polishing to form sub-millimeter zirconium oxide ceramic microbeads. According to the invention, a catalytic curing and UV curing composite molding technology is adopted, the size of the prepared zirconia ceramic microbead can reach a submillimeter level, and the zirconia ceramic microbead has high density and good wear resistance.
本发明公开了一种亚毫米级氧化锆陶瓷微珠的复合制备方法，属于陶瓷材料技术领域，在丙烯类单体、交联剂、分散剂以及钇稳定的氧化锆的混合溶液中加入引发剂和光固化剂形成氧化锆浆料；将所述氧化锆浆料注入含有催化剂的油浴液体石蜡中，并同时采用紫外光进行照射，从而形成氧化锆陶瓷微珠生坯，采用程序升温对生坯进行烧结，自抛光后形成亚毫米级氧化锆陶瓷微珠；本发明采用催化固化和UV紫外固化的复合成型技术，制备所得的氧化锆陶瓷微珠尺寸可达亚毫米级，且具有较高的密度和良好的耐磨性。
