Problems solved by technology

The physical characteristic of graphite itself is that its electrical conductivity is the best and highest among the materials used by human beings. Its actual electrical conductivity is higher than that of copper or even silver, and it cannot give full play to the electrical conductivity of graphene.

Abstract

The invention discloses a graphene electric-conduction glue preparation method, which comprises: sequentially placing a UV glue, an acrylate glue and an addition type liquid silicon rubber in a reaction kettle according to a certain ratio, and real-timely mixing and stirring the raw materials; after completing the adding, uniformly placing an electric-conduction agent in the reaction kettle, and uniformly mixing; adding an auxiliary agent, and mixing and stirring for 22-25 h to form a mixed liquid; increasing the temperature in the reaction kettle to 75-120 DEG C, and carrying out standing treatment on the mixed liquid for 6-9 h; placing the treated mixed liquid in an emulsifying machine, and carrying out emulsifying treatment on the mixed liquid for 20-50 min at a temperature of 45-60 DEGC; and obtaining the liquid-state graphene electric-conduction glue after the temperature recovers to a normal temperature. According to the present invention, the method can effectively ensure the quality of the graphene electric-conduction glue, is simple, and is suitable for wide-scale promotion.

Description

technical field [0001] The invention relates to the technical field of conductive glue preparation, in particular to a preparation method of graphene conductive glue. Background technique [0002] Graphene is a single-layer carbon atom surface material peeled off from graphite material. It is a two-dimensional structure of carbon and a "super material". It is harder than diamond and can stretch like rubber at the same time. It conducts electricity and heat better than any copper wire, and weighs almost nothing. The thickness of the graphite crystal film is only 0.335 nanometers. When 200,000 films are stacked together, it is only as thick as a hair. Graphene is a valuable material due to its small size, versatile processing and wide range of additive material applications. So far, graphene has a wide range of applications in new materials, solar cells, sensors, nanoelectronics, composite materials, field emission materials, and energy storage. The physical characteristic ...
