Thermal degreasing feed for zirconium oxide injection molding and preparation method and degreasing sintering process thereof
The invention belongs to the field of zirconium oxide ceramic injection molding, and particularly relates to thermal degreasing feed for zirconium oxide injection molding, and a preparation method anda degreasing sintering process thereof. The thermal degreasing feed for zirconium oxide injection molding is composed of 75-90 wt% of zirconium oxide powder and 10-25 wt% of a binder. The binder is prepared from the following raw materials in percentage by mass: 3-8% of a surfactant, 55-80% of a skeleton resin, 9-34% of a lubricating aid and 3-8% of a plasticizer. According to the thermal degreasing feed for zirconium oxide injection molding, the binder is reasonably matched, can be fully mixed with powder, and can be quickly removed in the degreasing process. The preparation method is reasonable in operation, convenient to repeat and suitable for large-scale batch production. The invention further provides the degreasing sintering process, the design is reasonable, the time is short, andmeanwhile the defects of bubbling, cracking and the like are avoided.
本发明属于氧化锆陶瓷注射成型领域，具体涉及一种氧化锆注射成型用热脱脂喂料及其制备方法与脱脂烧结工艺。所述的氧化锆注射成型用热脱脂喂料，由75‑90wt％的氧化锆粉体和10‑25wt％的粘结剂组成；粘结剂由以下质量百分比的原料组成：表面活性剂3～8％，骨架树脂55～80％，润滑助剂9～34％，增塑剂3～8％。本发明的氧化锆注射成型用热脱脂喂料，粘结剂之间搭配合理，既能与粉体充分混合，又能在脱脂过程中快速去除；本发明还提供其制备方法，操作合理，便于重复，适合规模化批量生产；本发明还提供其脱脂烧结工艺，设计合理，时间较短，同时不会产生鼓泡、开裂等缺陷。
