Feed for aluminum oxide injection molding, aluminum oxide ceramic and preparation method
The invention relates to the technical field of ceramic powder injection molding, and particularly discloses a feed for aluminum oxide injection molding, aluminum oxide ceramic and a preparation method.The feed for aluminum oxide injection molding is prepared from 83-86 parts of aluminum oxide ceramic powder and 14-17 parts of organic matter, the organic matter is prepared from 16 to 27 weight percent of polypropylene, 12 to 21 weight percent of polyethylene, 8 to 16 weight percent of PE compatilizer, 13 to 35 weight percent of paraffin and 10.5 to 28 weight percent of additive. The invention aims to provide the feed for aluminum oxide injection molding, so that a ceramic green body prepared by adopting the feed does not deform during glue discharging, is high in density and is easy to mold and demould; further, the aluminum oxide ceramic with high density, small shrinkage and high precision is provided; the invention further provides a preparation method of the aluminum oxide ceramic, the problems of toxicity, environmental protection and the like do not exist when a direct thermal degreasing mode is adopted for glue discharging, and when a solvent degreasing and thermal degreasing combined mode is adopted for glue discharging, the degreasing time is short, the efficiency is high, and the defects of deformation, bulging and the like are not prone to being caused.
本发明涉及陶瓷粉末注射成型技术领域，具体是公开了一种氧化铝注射成型用喂料、氧化铝陶瓷及制备方法，一种氧化铝注射成型用喂料，氧化铝注射成型用喂料的原料包括83‑86份的氧化铝陶瓷粉和14‑17份的有机物，有机物包括16‑27%wt的聚丙烯、12‑21%wt的聚乙烯、8‑16%wt的PE相容剂、13‑35%wt的石蜡和10.5‑28%wt的助剂。本发明目的是提供一种氧化铝注射成型用喂料，使采用此喂料制备的陶瓷生坯在排胶时不变形、致密度高、易于成型脱模；进而提供一种致密度高、收缩小、精度高的氧化铝陶瓷；还提供一种氧化铝陶瓷的制备方法，采用直接热脱脂的方式排胶时，不存在有毒、环保等问题，而采用溶剂脱脂和热脱脂相结合的方式进行排胶时，脱脂时间短，效率高，不易引起变形鼓包等缺陷。
