ANTIBACTERIAL AND ANTIFUNGAL JOINT FILLER COMPOUND AND ANTIBACTERIAL AND ANTIFUNGAL JOINT FILLER CONTAINING THE SAME

摘要

PURPOSE: To provide an antibacterial and antifungal joint filler compound which develops sufficient antibacterial and antifungal effect for a prolonged period on the without any adverse effect on human bodies. CONSTITUTION: This antibacterial and antifungal joint filler compound is prepared by using silver as an antimicrobial agent, using an inorganic colloid solution to give a silver nitrate inorganic colloidal solution, then diluting the colloidal solution with an appropriate amount of water. The inorganic colloidal solution is neutral-weak alkaline and any colloidal solution can be selected as for as it does not color. The colloidal solution preferably has a viscosity of about 1-10cp. The silver nitrate is dissolved in water in a concentration of 0.1-1.0wt.% calculated as metallic silver and the silver nitrate and the inorganic colloidal solution are mixed at a weight ratio of about 5/95-30/70Ag/ colloid.
