MANUFACTURING METHOD OF SILVER SUPERFINE NANOPARTICLES

摘要

The present invention relates to a process for the preparation of nano-silver for producing a silver particle of nano size using nitro inorganic clay in rapport with the stabilizer, in the manufacture of nano-silver, (1) dispersing the Laponite clay in water, When transparency of the dispersion is allowed to stand, and after adding a hydride (NaBH ₄₎ with sodium beam herein, reducing solution preparing step of preparing a reducing solution by stirring; (2) the reducing solution preparing step is a separate silver nitrate (AgNO _3), create a solution, the silver nitrate solution preparation step in creating a more silver nitrate solution was added ammonia water to the aqueous solution of silver nitrate; (3) the mixing step that was slowly added dropwise to the silver nitrate solution to the reduction solution, stirred vigorously for 1 to 3 hours; It characterized by including the yirueojim; and (4) a step of value standing for the mixture is 20 to 30 hours in the shade to be obtained in the mixing step.
