Preparation methods of resin compositions containing silver particles of nano size

摘要

PURPOSE: Provided is a resin composition containing nano-sized silver particles, which has antimicrobial property, antistatic property, conductivity, and excellent compatibility with a polymer composition such as plastic articles, paint, and ink. CONSTITUTION: The resin composition containing the nano-sized silver particles is produced by a capsulation process and a powdering process. The capsulation process is performed by mixing a silver colloid solution having a particle size of the silver being 1-100nm and a concentration of the silver being 1-90%, monomers, an initiator, an emulsifier, and ion exchange water and then performing emulsion-polymerization, suspension-polymerization, or microemulsion-polymerization to coat silver particles with the resin composition. And the powdering process is performed by spray-drying or coagulating the resin composition obtained by the capsulation process to obtain the resin composition powder. The obtained resin composition contains 0.01-90wt% of the silver and has an average polymerization degree of 100-100,000.
