载银Al2O3抗菌剂的制备及性能研究

Preparing and antibiotic property of Al2O3 doped-Ag

    摘要
  • 摘要: 报导了采用Al2O3为载体的银型无机抗菌材料的制备工艺及性能,所制备的无机抗菌材料具有良好的抗菌性能及安全性能,其中对大、小白鼠的急性经口毒性的LD50>5000mg/kg,亚急性毒性试验的无异常、无作用的量为100mg/kg·d;Ag2O的较佳掺入量为3wt%-5wt%,较佳的烧结温度范围为1000-1200℃。

     

    Abstract: The preparing technology and properties of Ag-type inorganic antibiotic material carried byAl2O3 were studied. The material has good antibiotic and safety property, the acute toxicity taken by stomata is LD50 ＞5000mg/kg to little and big white rats, and the normal quantity in subacute toxicitytest is 100mg/kg·d. The better quantity of Ag2O in the antibiotic material carried by Al2O3 is 3wt%-5wt%and the better sintering temperature range is 1000-1200℃.
