High-solid-content nano aluminum oxide ceramic feed and feed injection molding method
The invention relates to the field of ceramic powder injection molding, in particular to a high-solid-content nanometer aluminum oxide ceramic feed and a feed injection molding method. The preparation method comprises the following steps: uniformly mixing polyvinyl alcohol of a water-soluble system and microcrystalline wax and beeswax of an oil removal system through a composite surface active system consisting of stearic acid, oleic acid and dibutyl phthalate, and then dissolving and removing various components at one time through a compound solvent consisting of n-heptane, alcohol and pure water, thereby obtaining the sintered compact high-solid-content and high-oil-removal-rate wax with high solid content. And the alumina product is not easy to crack. According to the high-solid-content nanometer aluminum oxide ceramic feed, the proportion of nanometer aluminum oxide reaches up to 88 wt%-89 wt%, the adding amount of other organic matter is only 11 wt%-15 wt%, and the ceramic sintering density of an obtained high-density aluminum oxide ceramic injection product reaches up to 3.96%.
本发明涉及陶瓷粉末注射成型领域，具体为一种高固含量的纳米氧化铝陶瓷喂料及喂料注射成型方法。本发明通过硬脂酸、油酸和邻苯二甲酸二丁酯组成的复合表面活性体系将水溶性体系的聚乙烯醇和油脱体系的微晶蜡及蜂蜡混合均匀，再通过正庚烷‑酒精‑纯水组成的复配溶剂，一次性溶脱去除多种成分，得到烧结致密的高固含量，不易开裂的氧化铝产品。本发明的高固含量的纳米氧化铝陶瓷喂料中的纳米氧化铝占比高达88wt％‑89wt％，其余有机物的添加量仅为11wt％‑15wt％，所得高密度的氧化铝陶瓷注射产品的陶瓷烧结密度高达3.96％。
