Zirconia ceramic sintered gasket and preparation method thereof
The invention belongs to the field of ceramic chips, and discloses a zirconia ceramic sintered gasket preparation method, which comprises: carrying out ball milling, defoaming aging and casting on YSZ powder, a solvent, a dispersant and a glue to obtain a casting sheet; then drying, punching, degreasing, sintering and the like are carried out on the cast sheet to obtain a zirconia ceramic sintered gasket; wherein the YSZ powder is formed by mixing zirconium oxide powder and yttrium oxide powder according to the mass ratio of 92%: 8%, casting is temperature-zone temperature increasing casting, and the temperature of a first temperature zone is 30-45 DEG C; the temperature of the second temperature zone is 50-60 DEG C; the temperature of the first temperature zone is 65-70 DEG C, the temperature of the third temperature zone is 65-70 DEG C, the glue is prepared by mixing a plasticizer, a binder, toluene and isopropanol according to a certain mass ratio, the plasticizer is selected from at least one of tributyl phosphate and dibutyl phthalate, and the binder is selected from at least one of polymethyl methacrylate and polyvinyl alcohol. In addition, the invention further discloses the zirconia ceramic sintered gasket which is prepared through the method.
本申请属于陶瓷片领域，公开了一种氧化锆陶瓷烧结垫片的制备方法，通过将YSZ粉末、溶剂、分散剂、胶剂，进行球磨、脱泡陈腐、流延，得到流延片；然后将流延片进行烘干、冲切、脱脂、烧结等工艺，得到氧化锆陶瓷烧结垫片；其中YSZ粉末由氧化锆粉末及氧化钇粉末按质量比92％：8％混合组成，且流延为分温区温度递增流延，第一温区温度为30～45℃；第二温区温度为50～60℃；第三温区温度为65～70℃，所述胶剂由增塑剂、粘结剂、甲苯及异丙醇按一定的质量比混合制得，其中增塑剂选自磷酸三丁酯、邻苯二甲酸二丁酯中的至少一种，粘结剂选自聚甲基丙烯酸甲酯、聚乙烯醇中的至少一种。此外，本申请还公开了一种氧化锆陶瓷烧结垫片，通过上述方法制得。
