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.
