Ultrafine alumina ceramic powder injection molding POM-based formula system and application thereof
The invention belongs to the field of ceramic powder injection molding, and particularly discloses an ultrafine alumina ceramic powder injection molding POM-based formula system and application thereof, the ultrafine alumina ceramic powder injection molding POM-based formula system comprises the following components by mass: 77-81% of alumina nano ceramic powder and 19-23% of a binder; wherein the binder comprises the following components in percentage by weight: 70-80% of POM (Polyoxymethylene); 8-15% of a skeleton component and 2-5% of an antioxidant; 4-8% of a hyperdispersant; and 15% of a lubricant. According to the formula system, the nano aluminum oxide ceramic feed with good fluidity and stable performance and a complex thin-wall product can be prepared, the catalytic degreasing efficiency is high, the defects of cracking and the like during degreasing are avoided, the sintered product is high in density, uniform and stable, and the product can be applied to production of precision parts with high quality requirements, such as ceramic oxidation sensors, textile ceramics and the like. And great economic benefits are achieved.
本发明属于陶瓷粉体注射成型领域，具体公开了一种超细氧化铝陶瓷粉体注射成型POM基配方体系及其应用,所述超细氧化铝陶瓷粉体注射成型POM基配方体系由以下质量百分比的成分组成：氧化铝纳米陶瓷粉体77‑81%，粘结剂19‑23%；其中：粘结剂中各组分的占比为：POM 70‑80%；骨架组分8‑15%，抗氧化剂2‑5%；超分散剂4‑8%；润滑剂15%。本发明涉及的配方体系，能够制备出流动性好，性能稳定的纳米氧化铝陶瓷喂料，成型复杂薄壁产品，且催化脱脂效率高，脱脂无开裂等不良，烧结后产品的密度高，均一稳定，可应用高质量要求的精密零部件生产，如陶瓷氧化传感器、纺织瓷等，具有很大的经济效益。
