Abstract

The invention relates to a preparation method of nano-silver powder with high sintering activity, the preparation method comprises the following steps that S1, nano-silver is injected into a first grinding device through a feed port of the first grinding device for primary grinding; S2, the nano-silver subjected to primary grinding is injected into a second grinding device through a feeding port of the second grinding device and is ground again through high-pressure airflow, and the nano-silver meeting the particle size is injected into a sintering device through a discharging port of the second grinding device; and S3, a central control unit controls the sintering device to sinter the nano-silver. The central control unit is arranged, the produced sintered nano-silver meets the preset standard according to the obtained particle size reject ratio of the nano-silver, the volume change rate during sintering, the sintering temperature and the sintering time, meanwhile, the jet flow frequency, the grinding time of the first grinding device and the power parameters of a power device are adjusted, and therefore, the particle size of the love nano-silver meets the preset standard.

Description
