Preparation method of zirconium oxide wear-resistant particles
The invention discloses a preparation method of zirconium oxide wear-resistant particles, which comprises the following steps: putting zirconium oxide powder, deionized water, acrylamide, N, N-dimethyl bisacrylamide and ammonium polyacrylate into a ball milling tank, and carrying out ball milling to obtain low-viscosity slurry; preparing an ammonium persulfate aqueous solution, and uniformly mixing with silica gel; dropwise adding tetramethylethylenediamine into the slurry obtained by ball milling, and uniformly stirring; and sucking the slurry by using a 1ml dropper, dripping the slurry into silica gel, and forming to obtain the zirconium oxide wear-resistant particles. The particle size can be controlled according to the size of the dropper opening; in the preparation process, zirconia and alumina powder can be recovered and reused after loss, and the silica gel mold can be repeatedly used; the prepared zirconium oxide toughened aluminum oxide wear-resistant particles are better in wear-resistant effect and longer in service life.
本发明公开了一种氧化锆耐磨颗粒的制备方法，该方法包括以下步骤，将氧化锆粉末、去离子水、丙烯酰胺、N，N‑二甲基双丙烯酰胺、聚丙烯酸铵装入球磨罐中，经过球磨得到低黏度料浆；配制过硫酸铵水溶液与硅胶混合均；将四甲基乙二胺滴入球磨得到的料浆中，搅拌均匀；取1ml滴管吸入料浆，将料浆滴入硅胶中，成型得到氧化锆耐磨颗粒。本发明可以通过滴管口的大小来控制颗粒尺寸的大小；在制备过程中，出现的氧化锆、氧化铝粉末损失可以回收再次利用，硅胶模具可以重复使用；制备得到的氧化锆增韧氧化铝耐磨颗粒，耐磨效果更佳，使用寿命更长。
