Zirconium oxide microspheres and preparation method thereof
The invention discloses zirconium oxide microspheres and a preparation method thereof. The preparation method comprises the following steps: heating and titrating zirconium oxide high-solid slurry anda titrating emulsion, settling and condensing to form zirconium oxide spheres, and then, carrying out low-temperature glue discharging and sintering. The mass ratio of the zirconium oxide high-solidslurry to the titration emulsion is (4-6): 1, the zirconium oxide high-solid slurry is prepared from the following components in parts by weight: 80 to 100 parts of zirconium oxide powder, 16 to 20 parts of deionized water, 1 to 3 parts of an ammonium polyacrylate dispersing agent, 2 to 3 parts of acrylamide and 0.2 to 0.4 part of N' N-methylene bisacrylamide, the titrating emulsion is prepared from the following components in percentage by volume: 60%-80% of dimethyl silicone oil, 19-39% of propylene glycol and 1% of Span 80. According to the zirconium oxide microspheres and the preparation method thereof, the problems of poor quality and dimensional stability, easiness in bead breaking and the like of the existing zirconium oxide microspheres are solved, and the zirconium oxide microspheres have the advantages of simple process, zero pollution, good product dimensional stability and the like, and are easy to screen and stable in quality.
本发明公开了一种氧化锆微珠及其制法，其是由氧化锆高固份浆料和滴定乳液经加热滴定后沉降并凝结成氧化锆球体，之后经低温排胶和烧结后得到的，所述氧化锆高固份浆料和滴定乳液的质量比为4‑6:4‑6，其中氧化锆高固份浆料是由如下重量份数的组分制成的：氧化锆粉体80‑100份、去离子水16‑20份、聚丙烯酸铵分散剂1‑3份、丙烯酰胺2‑3份、N’N‑亚甲基双丙烯酰胺0.2‑0.4份；滴定乳液是由如下体积百分数的组分制成的：60％‑80％二甲基硅油、19％‑39％丙二醇、1％司盘80。本发明氧化锆微珠及其制备方法，解决了现有氧化锆微珠的质量和尺寸稳定性差以及容易碎珠等问题，具有工艺简单、零污染、产品尺寸稳定性好等优点，容易筛分且质量稳定。
