Nano-silver paste large-scale production device

Abstract

The invention relates to the technical field of production equipment, in particular to a nano-silver paste large-scale production device which comprises a device body, a mixing box, a dispersing box and a heating box; a feeding port is formed in the top end of the device body, a rack is arranged at the bottom end of the device body, a through pipe is connected to the bottom end of the feeding port, and a stirring mechanism is arranged at the inner end of the mixing box. A motor is connected to the bottom end of the stirring mechanism, a belt is connected to one end of the motor, a dispersing mechanism is arranged at the inner end of the dispersing box, an ultrasonic oscillator is arranged at one end of the dispersing box and located on the outer side of the device body, a discharging portis connected to the back end of the dispersing box, a far infrared generator is arranged at one end of the heating box and located on the outer side of the device body, and the bottom end of the heating box is connected with a firstperistaltic pump. According to the device, all single devices are concentrated in the same device, so that the practicability of the production device is improved, andthe device is more efficient in use.

Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to a large-scale production device of nano-silver paste. Background technique [0002] Silver materials are widely used in conductive pastes because of their good electrical conductivity and chemical stability. According to relevant data, in 2016, 561.9 million ounces of silver (about 16,000 tons) were consumed in the industrial manufacturing field, of which 233.6 million ounces were consumed in the electrical and electronic field, 55.4 million ounces were consumed in the welding field, and 76.6 million ounces were consumed in the photovoltaic field. ounces, most of which need to use conductive silver paste. It can be seen that the market scale of silver conductive paste is very large, but the current silver paste mainly uses micron-sized spherical or flake silver particles as conductive components. In order to reduce costs, researchers Focusing on the development of n...
