Composite material for antibacterial porcelain teeth, and preparation method thereof
The invention relates to the technical field of medical materials, and concretely relates to a composite material for antibacterial porcelain teeth, and a preparation method thereof. The composite material for antibacterial porcelain teeth is prepared from, by weight, titanium dioxide powder, zinc acetate, aluminum oxide, silver acetate, zirconium acetate, ammonia water, glycerol, anhydrous ethanol and deionized water. Insoluble weak base groups are prepared from acetates and ammonia water, and are heated and decomposed to obtain silver oxide modified oxide groups, and the modified zirconium oxide and zinc oxide have high microstructure uniformity, so that the composite material obtained by sintering is high in strength, high in hardness, strong in cold and heat change resistance, corrosion-resistant and wear-resistant; and the material is filled with a large amount of silver, so that bacteria can be prevented from living and metabolizing in gaps of teeth to generate unpleasant smell and organic acid to corrode the teeth.
本发明涉及医疗材料技术领域，具体为一种抑菌烤瓷牙用复合材料及其制备方法；一种抑菌烤瓷牙用复合材料，该复合材料由以下重量份数的成分组成：二氧化钛粉末、乙酸锌、氧化铝、乙酸银、乙酸锆、氨水、丙三醇、无水乙和去离子水；本发明所制备的复合材料利用乙酸盐和氨水制得难溶性弱碱基团，并将其加热分解得到经氧化银修饰的氧化物基团，修饰过的修饰氧化锆和氧化锌具有较高的微观形貌均一性，因而因而烧结得到的复合材料强度大、硬度高、对抗冷热变化能力强，耐腐蚀，耐磨损；材料内部填充着大量银，可避免细菌在牙齿的缝隙间生存代谢从而产生难闻的气味和有机酸来腐蚀牙齿等优点。
