Zirconium oxide composite carrier for vacuum evaporation and preparation method thereof
The invention discloses a zirconium oxide composite carrier for vacuum evaporation and a preparation method thereof. The carrier is prepared by sintering the following raw material components in parts by mass: 10-30 parts of zirconium oxide, 1-7 parts of carbon powder, 0.05-6 parts of a pore forming agent and 1-9 parts of a high-temperature-resistant binder, the specific surface area of the composite carrier is 280-310 m < 2 >/g. The preparation method of the carrier comprises the following steps: mechanically activating zirconium oxide and carbon powder, and sintering at high temperature to obtain carbon-zirconium oxide composite particles; and uniformly mixing the carbon-zirconium oxide composite particles, a pore-forming agent and a high-temperature-resistant binder, carrying out mold pressing to obtain a composite carrier precursor, and sequentially carrying out low-temperature microwave pore-forming, cleaning and drying on the composite carrier precursor to obtain the carbon-zirconium oxide porous carbon carrier. According to the composite carrier, by strictly limiting the ratio of the raw material components, the specific surface area and porosity of the carrier are greatly improved, meanwhile, the excellent chemical stability of the carrier is guaranteed, the problems that a steel wool carrier is prone to rusting and deterioration, a coating agent is prone to remaining and the like are solved, and reutilization of the coating carrier is achieved.
本发明公开了一种用于真空蒸镀的氧化锆复合载体及其制备方法。该载体：由包括以下质量份数在内的原料组分烧结所得：氧化锆10~30份，碳粉末1~7份，造孔剂0.05~6份，耐高温粘结剂1~9份；所述复合载体的比表面积为280~310m2/g。该载体的制备方法为：将氧化锆和碳粉末机械活化后进行高温烧结，得碳‑氧化锆复合微粒；将碳‑氧化锆复合微粒、造孔剂和耐高温粘结剂混合均匀后经模压，得到复合载体前驱体，再将复合载体前驱体依次进行低温微波造孔、清洗和干燥，即得。该复合载体通过严格限定各原料组分之间的配比，大幅提高载体比表面积和孔隙率的同时还保证了载体优异的化学稳定性，解决了钢丝棉载体易生锈变质、镀膜剂易残留等问题，实在了镀膜载体的重复利用。
