Benefits of technology

[0012]Another object of the present invention is to provide a preparation method, which does not use a separate physical dispersing device or dispersing agent and thus has simple and economic preparation process.
[0015]Therefore, an object of the present invention is to provide a method for preparing resin compositions containing nano silver particles, in which nano silver particles dispersed in the resin have uniform sizes and high dispersibility and can be dispersed in the resin with high concentration by using a silver complex having a specific structure which is highly stable and highly soluble in various vinyl monomers and decomposed at a low temperature to easily form nano silver particles.Technical Solution

Problems solved by technology

Therefore, there are disadvantages that the preparation process is complex and uneconomic since a dispersing agent is needed to facilitate the dispersion and a physical force, e.g. an extruder, a melter, a stirrer or a super mixer is also needed.
However, since the colloidal solution of nano silver particles is used in this method, an emulsifier or a dispersing agent is needed to facilitate the dispersion of the nano silver particles and there is a limitation in uniformity of the nano silver particles dispersed in the resin composition.
However, polar solvent for dissolving the silver salt is necessarily required since the silver salt such as silver nitrate and silver acetate is used and it is difficult to prepare a resin composition in which the nano silver particles are dispersed with high concentration since there is a limitation in uniformity and dispersibility of the nanoparticles contained in the polymer resin composition.

preparation example 2

[0038]In a 50 mL Schlenk flask equipped with a stirrer, 3.72 g (11.61 mmol) of 2-ethylhexylammonium 2-ethylhexylcarbonate (viscous liquid) was dissolved in 10 mL of methanol. 1.0 g (4.31 mmol) of silver oxide was then added. The reaction solution was initially a black slurry but it turned transparent as the reaction was performed. After 2 hours of reaction, a colorless, transparent solution was obtained. The resultant solution was filtered with a 0.45 micron membrane filter to remove unreacted silver oxide. Then, the solvent was removed under vacuum to obtain white solid. The solid was dried and weighed to obtain 4.02 g of a silver complex (yield=85.2%).

preparation example 3

[0039]In a 50 mL Schlenk flask equipped with a stirrer, 4.86 g (25.37 mmol) of 2-ethylhexylammonium bicarbonate (viscous liquid) was dissolved in 10 mL of methanol. 1.0 g (4.31 mmol) of silver oxide was then added. The reaction solution was initially a black slurry but it turned transparent as the reaction was performed. After 2 hours of reaction, a colorless, transparent solution was obtained. The resultant solution was filtered with a 0.45 micron membrane filter. Then, the solvent was removed under vacuum to obtain white solid. The solid was dried and weighed to obtain 4.33 g of a silver complex (yield=73.9%).

preparation example 4

[0040]In a 50 mL Schlenk flask equipped with a stirrer, 2.04 g (10.75 mmol) of isobutylammonium isobutylcarbamate (white solid, melting point: 80-82° C.) was dissolved in 10 mL of methanol. 1.0 g (4.31 mmol) of silver oxide was added and reaction was performed at room temperature. The reaction solution was initially a black slurry but it turned transparent as complex was produced. After 2 hours of reaction with stirring, a colorless, transparent solution was obtained.

[0041]The resultant solution was filtered with a 0.45 micron membrane filter. Then, the solvent was removed under vacuum to obtain white solid. The solid was dried and weighed to obtain 2.87 g of a silver complex (yield=94.4%).
