技术领域
本发明涉及一种新型生物陶瓷多孔材料的制备方法,特别是一种HA-TiO2复合型生物陶瓷多孔材料的制备方法。
背景技术
羟基磷灰石(HA,Ca10(PO4)6(OH)2)是人体中骨骼、牙齿的主要无机成分,具有良好的生物相容性和生物活性,在临床医学上,已被广泛应用于骨组织的修复与替代。羟基磷灰石粒子可以在生物体内环境中稳定存在并与细胞发生一定程度的相互作用。目前已证实纳米羟基磷灰石对多种癌细胞有抑制作用,而对正常细胞无不良影响,而其表面在某种程度上还可促进细胞的增殖,但是单一的HA用于生物陶瓷材料并不妥当,其机械性能较差,考虑到生物陶瓷材料在生物医学工程领域的后续应用,如将同样具有良好生物相容性的二氧化钛(TiO2)与羟基磷灰石进行复合,同时在制备过程中加入适当的致孔剂,则可望获得生物相容性能良好、机械性能良好,同时又具有较强吸附载药能力的新型生物陶瓷多孔材料。
发明内容
本发明的目的是为了克服现有的生物陶瓷材料或机械性能不足,或生物相容性不够好,或多孔材料成孔方式成本较高等缺点,提供一种制备简单、成本低廉、合成安全的新型生物陶瓷多孔材料的制备方法。
按照本发明提供的技术方案,首先将羟基磷灰石和二氧化钛按一定比例混合均匀,然后按照30%过氧化氢溶液:Dolapix CE64:混合粉末其重量比为4:5:9的比例配置反应原浆,反应24小时以上,将所得产品在室温下干燥后,在105℃下烘干7小时以上,充分去除水分后,将所得产品在1300℃下烧结3小时,升温速度为2℃/min。
所述新型HA-TiO2生物陶瓷多孔材料,其孔径直径为50~1000μm,其杨氏模量、抗压强度和弯曲强度分别为1.8±0.2GPa,6.5±1.1MPa,2.2±0.3MPa。
本发明涉及一种新型HA-TiO2生物陶瓷多孔材料的制备方法,采用了以下技术方案:
1、配制羟基磷灰石和二氧化钛混合粉末:将市售微米级羟基磷灰石和二氧化钛粉末按照适当比例混合均匀;
2、配制反应原浆溶液:将上述第一步中的羟基磷灰石和二氧化钛混合粉末与30%过氧化氢溶液、Dolapix CE64进行混合搅拌,按照适当比例配制成反应原浆;
3、在持续搅拌的情况下使上述第二步中的反应原浆溶液充分搅拌一定时间,使其反应完全;
4、将上述第三步的混合反应原浆溶液在室温下充分干燥,初步去除其中所含有的水分;
5、将上述第四步中已经经过初步干燥后的初步产物在105℃下烘干,充分去除其中所含有的水分;
6、将上述第五步中已去除了水分的产物置于马弗炉中,将所得产品在1300℃下烧结,采用适当的阶梯升温速度;
7、烧结完成后,将上述第六步的反应体系冷却至室温,将产品置于干燥器中保存,即可得到新型HA-TiO2生物陶瓷多孔材料。
本发明所提供的新型HA-TiO2生物陶瓷多孔材料的制备方法克服了现有的生物陶瓷材料或机械性能不足,或生物相容性不够好,或多孔材料成孔方式成本较高等缺点,本制备方法绿色安全、成本低廉,工艺简单,适于规模生产,对于生物医学工程领域具有重要应用价值。
