| titleOfInvention | High concentration nano-silver colloid and preparation method for nano-silver colloid precursor |
| abstract | The present invention relates to a high concentration nano-silver colloid and a preparation method for nano-silver colloid precursor. The preparation method includes the following step; providing a solution containing silver salt and urea to mix with a NaOH aqueous solution for obtaining a precursor precipitate; using centrifugation method to separate said precipitate; dispersing the precipitate into an ethanol solution to obtain a nano-silver colloid precursor; and mixing the nano-silver colloid precursor with a reductant and a dispersant to obtain a high concentration nano-silver colloid solution, wherein the silver colloid precursor is a solid silver precursor, and a heterogeneous phase reaction with the reductant is carried out such that it has advantages of slower reduction rate for easily controlling the distribution of silver colloid particle size. Therefore, the problems such as purification insufficiency in conventional nano-silver colloid and dispersion insufficiency or non-uniformity of homogeneous phase reactants, which are caused by excessive solution viscosity resulted from the addition of high concentration dispersant, can be solved. |
