METALLIC ANTIBACTERIAL AGENT AND ANTIBACTERIAL MATERIAL

摘要

PURPOSE: To provide an inexpensive metallic antibacterial agent having high safety and high and long-acting bactericidal effect. CONSTITUTION: This powdery metallic antibacterial agent is composed of ceramic particles or base metal particles having an average particle diameter of 0.01-0.5μm and antibacterial metal particles having an average particle diameter of 0.0001-0.1μm and attached to the surface of the ceramic particles, etc., in dispersed state in an amount corresponding to 0.1-60wt.% based on the weight of the ceramic particles or the base metal particles. This antibacterial material contains the metallic antibacterial agent embedded in a matrix in a partly exposed state.
