[0031]

[0032] In above-mentioned embodiment, the preparation / processing method of graphene, glass powder, organic vehicle and embodiment 1~5 conductor slurry is as follows:

[0033] Graphene surface coating: add a surfactant to the graphene, soak and wet the graphene with the surfactant for 6 hours, and then dry it at 60°C for use. A layer of material is coated on the surface of graphene to protect it and facilitate the subsequent air environment operation process. The coated material will also make graphene evenly disperse into the carrier system.

[0034] The preparation method of the glass powder is as follows: use a planetary ball mill to grind glass (such as glass-ceramic) for 3 hours, and use it after detection.

[0035] The preparation method of the organic carrier is as follows: firstly dry the polymer resin, then...

Abstract

The invention relates to a conductor paste and a conductor material. The conductor paste comprises the following components in percentage by weight: 20%-40% of silver powder, 0.01%-20% of graphene, 1%-8% of glass powder and 45%-70% of an organic carrier. The silver content in the conductor paste is extremely low and is only 20%-40%, so that the thinking constraint of traditional high silver and high conductivity is broken through, the conductor paste is a new breakthrough in the limit field of domestic electronic materials, the production cost can be effectively reduced for downstream enterprises, and the living space is effectively improved; Meanwhile, graphene is added into the conductor slurry, and the defects caused by silver reduction are overcome by utilizing the excellent electricalproperty of graphene.

Description

technical field [0001] The invention relates to a slurry and its application, in particular to a conductive slurry and a conductive material. Background technique [0002] Since the generation of chip resistors, the back electrode paste has always been available. The initial manufacturers include Japan's Sumitomo, South Korea's Dazhou, etc. With the advancement of the cost of chip resistor companies, we have developed a metal content of 50%. The back electrode paste replaced the import in one fell swoop. However, a high metal content back electrode paste will increase the production cost. The field of conductor materials needs to be constantly explored and challenged, and the potential and limits of technology must be continuously tapped. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a conductive paste with low production cost and good electrical conductivity and a cond...
