Technical Field

[0001] The utility model belongs to the technical field of stirring devices, and in particular relates to a stirring device for conductive slurry. Background Art

[0002] Conductive paste, also known as conductive glue, is a mixture of precious metal powder and base metal powder, glass powder and synthetic resin. After adding solvent, it can be made into a graphite or graphite-like material. Therefore, when making conductive paste, it is often necessary to stir and mix the above materials.

[0003] The production of conductive slurry is affected by equipment and process. When pouring the semi-finished material particle powder, large lumps are likely to exist. However, the existing stirring device directly chooses to ignore it and relies on the blades on the stirring shaft to stir and disperse the lumps. However, a small part of the lumps harden on the surface after contacting the resin, and the internal material cannot be dispersed, resulting in unsatisfactory performance of the conductive slurry.

[0004] Therefore, in order to solve the above problems, it is necessary to design a stirring device for conductive slurry. Utility Model Content
