载银无机抗菌剂的制备及其性能研究

以磷酸氢钙为载体,银锌离子为抗菌剂,在1 050oC氧化气氛下烧结制得抗菌性能显著,耐候性好的无机抗菌剂。研究了银锌离子用量及烧结对抗菌性能和耐候性的影响。实验表明:随着银锌离子质量分数的增加,材料的抗菌能力提高;加入锌离子不仅能提高材料的抗菌能力,还能改善材料的耐候性;当Zn (NO3)2的质量分数大于AgNO3的质量分数2倍时,可生产出不变色的抗菌剂;烧结使银锌离子与载体结合更牢固,有利于改善材料的耐候性。

Preparation and Study on Properties of Ag-Series Inorganic Antibacterial Agent

By adding silver ions and zinc ions in CaHPO4 and sinter at 1 050oC, a novel Ag-series inorganic antibacterial agent with excellent bactericidal property and weather resistance can be made.The influence of ions concentration and sinter on bactericidal property and weather resistance are study. The tests result show that the bactericidal ability increase with increasing of silver ions and zinc ions; not only bactericidal ability increase, but also weather resistance of this antibacterial agent can be increased by adding zinc ions; the antibacterial agent do not change their colour when the concentration of Zn(NO3)2 is more than 2 times of AgNO3; sinter is beneficial to improving the weather resistance of this material.
