Antibacterial glass ceramic repair material and preparation method thereof

The invention discloses an antibacterial glass ceramic repair material which contains the following raw material components in percentage by mass: 60-75% of SiO2, 26-30% of Li2O, 0.01-0.03% of Cu, 0.05-0.08% of Ag, 0.2-0.6% of a complex rare-earth element and 0.05-0.2% of composite plant essential oil. According to the antibacterial glass ceramic repair material disclosed by the invention, lithiumsilicate glass ceramics are taken as a glass matrix, and an appropriate amount of the complex rare-earth element is added to improve the surface microenvironment of the repair material. Meanwhile, byadding an appropriate amount of a compound stabilizer and elements such as Ag and Cu, the yellowing resistance and spectral antimicrobial property of the repair material are effectively improved. 本发明公开了种抗菌型玻璃陶瓷修复材料，其按原料质量百分比计包括如下组分：SiO60～75％、LiO 26～30％、Cu 0.01～0.03％、Ag 0.05～0.08％、复合稀土元素0.2～0.6％、复合植物精油0.05～0.2％。本发明以硅酸锂玻璃陶瓷为玻璃基质，同时通过添加适量复合稀土元素以改善该修复材料的表面微观环境，同时通过添加适量复合稳定剂和Ag、Cu元素以有效提高其耐黄性能和光谱抗菌性能。
