AN ANTIMICROBIAL SILVER-SILICA-SILICONE COMPOSITE FOR PLASTIC AND POLYMER APPLICATION AND THE METHOD OF PREPARATION THEREOF

摘要

[0076] The present invention provides with the composition of the silver-silica-silicone composites and process for the preparation thereof. The process comprises an aqueous or solvent based nano silver particulate suspension mixed with silicon dioxide i.e. SiO2 at high shear. Silicone oil is added and the temperature of the solution is increased. The aqueous particulate silver suspension are phase transferred at higher temperature without any binding agent. After complete removal of moisture, precipitated form of silicon dioxide is added to get the silver-silica-silicone composite powder. The silver-silicone-silica composite obtained by the process of present invention is used in antibacterial finish for control of growth of microbes and to avoid formation of stains and odour on consumer applications such as toothbrush, medical application such as medical devices, industrial application such as kitchen surfaces etc.
