摘要： 目的:将粉末状羟基磷灰石晶须纳米氧化锌(HAPw/ n-ZnO)复合材料制备成多孔颗粒状。方法:以HAPw/n-ZnO复合材料为原料,加入硅溶胶在不同温度下煅烧并借X射线衍射(XRD)分析确定硅溶胶与HAPw/n-ZnO发生化学反应的温度。再加入控制粒径100~250 μm的造孔剂聚甲基丙烯酸甲酯(PMMA)及30wt%的硅溶胶为粘接剂,以魔芋萄甘聚糖(KGM)凝胶冷压过模成型烧结后粉碎过筛,应用X射线衍射、扫描电镜、万能试验机、阿基米德排水法测试分析。结果:硅溶胶与HAPw/n-ZnO在高于600 ℃时会发生反应;烧结600 ℃保温2 h孔隙率最为理想;造孔剂含量为40 VOL%时孔隙率为64.2%,抗压缩强度为0.9 MPa。结论:造孔剂法可制备多孔HAPw/n-ZnO复合材料。

Abstract: Objective: To prepare porous HAPw/n-ZnO granules fromHAPw/n-ZnO powder. Method: HAPw/n-ZnO powder was mixed with silicon sol and calcined at different temperatures. X-ray diffraction (XRD) analysis was used to determine the optimal reaction temperature for the mixture. To obtain granules with pore diameter at about 100-250um, polymethyl methacrylate (PMMA) and 30wt% of silica sol were respectively employed as pore-forming agent and binder. XRD, scanning electron microscope (SEM), universal testing machine, and Archimedes principle were employed to analyze the new material. Results: The mixture of silicon sol and HAPw/n-ZnO could react at the temperature higher than 600℃. Heat preservation at 600℃ for 2 hours led to the optimal porosity. 64.2% porosity could be obtained when pore-forming agent content was 40% (v:v), and the compression strength was 0.9MPa. Conclusion: Porous granular HAPw/n-ZnO composite material can be efficiently prepared by pore-forming agent method.
