The present invention relates to a kind of preparation method of Nanometer Copper activating solution, technique is simple, is sufficiently mixed the reducing agent and stabilizer, prepares the Nanometer Copper activating solution that stability is good, activation capacity is strong.The Nanometer Copper activating solution of the present invention, using nano copper particle as activated centre, used reducing agent can avoid nanometer copper particle from being oxidized, and Nanometer Copper activating solution is had strong inoxidizability.It is charge that used stabilizer can improve nanometer copper particle, prevent from reuniting between particle, be that Nanometer Copper activating solution has long-time stability, storage time was up to more than 2 years.Compared with existing colloid palladium, the Nanometer Copper activating solution of the inventive method, using cheap metallic copper as activated centre, dispergation processing need not be carried out in use, simplifies the use step of activating solution, technique is simple, green. |
