ZTA ceramic powder catalytic degreasing type injection feed for large-size thick-wall injection molding and preparation method of ZTA ceramic powder catalytic degreasing type injection feed
The invention belongs to the field of ceramic powder injection molding, and particularly discloses a ZTA ceramic powder catalytic degreasing type injection feed for large-size thick-wall injection molding and a preparation method thereof.The injection feed is prepared from, by mass, 75-78% of ZTA ceramic powder and 22-25% of binder; wherein the binder comprises the following components in percentage by weight: 78-85% of POM (Polyoxymethylene); 4.5-6% of a skeleton component and 2.5-5% of an antioxidant; 3-5% of a hyperdispersant; and 1-4% of a lubricant. According to the formula and the preparation method, the ZTA ceramic feed with good fluidity and stable performance can be prepared, the ZTA ceramic feed is used for forming large-size thick-wall complex-shape products such as blood dividing valve plates, 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 ZTA ceramic feed can be applied to production of precision parts with high quality requirements. Therefore, the blood separating valve plate has great economic benefits.
本发明属于陶瓷粉体注射成型领域，具体公开了一种用于大尺寸厚壁注射成型的ZTA陶瓷粉体催化脱脂型注射喂料及其制备方法,所述注射喂料按质量百分比计算，由以下成分组成：ZTA陶瓷粉体75‑78%，粘结剂22‑25%；其中粘结剂中各组分的占比为：POM 78‑85%；骨架组分4.5‑6%，抗氧化剂2.5‑5%；超分散剂3‑5%；润滑剂1‑4%。根据本发明所述的配方和制备方法，能够制备出流动性好，性能稳定的ZTA陶瓷喂料，用于成型大尺寸厚壁复杂形状产品如分血阀片，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，如分血阀片等，具有很大的经济效益。
