Manufacturing equipment of high-dispersion conductive adhesive and preparation method

Abstract

The invention discloses manufacturing equipment of a high-dispersion conductive adhesive, which comprises an adhesive manufacturing tank A, a pair of conveying pipes with the same structure, four valves with the same structure, a connecting pipe, a ceramic emulsifying machine, a screw pump and an adhesive manufacturing tank B, wherein the inner cavities of both the adhesive manufacturing tank A and the adhesive manufacturing tank B are provided with a stirring paddle capable of rotating around the respective axis, the pair of conveying pipes are respectively arranged at the upper and lower sides between the adhesive manufacturing tank A and the adhesive manufacturing tank B, the connecting pipe is arranged at the middle of the pair of conveying pipes along the vertical direction, the outer wall of the connecting pipe is provided with the ceramic emulsifying machine and the screw pump. According to the invention, a binding agent and a conductive agent in the conductive adhesive can befully dispersed by the ceramic emulsifying machine, thereby achieving an ideal suspension dispersion state, ensuring the processing performance of battery slurry, and effectively reducing the internalresistance of batteries. It is ensured that there is no residual non-emulsified adhesive solution through repetitively emptying and fully filling the two adhesive manufacturing tanks, and the consistency of batteries produced by the same batch of slurry is improved.

Description

technical field [0001] The invention relates to the technical field of conductive adhesives, in particular to a production equipment and a preparation method of highly dispersive conductive adhesives. Background technique [0002] Lithium-ion batteries have the advantages of high voltage, long cycle life, good safety performance, environmental protection and pollution-free, light weight and small body, and have been widely used in many portable products such as mobile phones, notebooks, mobile power supplies, digital products, and wearable devices; [0003] Usually, in the production process of lithium-ion batteries, active materials, conductive agents, binders and solvents need to be added to the planetary mixer at one time according to the proportion, but the planetary mixer has limited dispersion effect on conductive carbon black and other very fine particles, which is not easy meet the ideal requirements. Contents of the invention [0004] The purpose of the present i...
