The present application relates to the technical field of
electrode paste, and discloses a high-
conductivity and low-energy-consumption
electrode paste prepared by closed baking and a preparation process.The
electrode paste of the present application is composed of composite carbonaceous base material, conductive
graphite powder, modified
pitch binder and
boron-
silicon composite modifier, and can be added with two-dimensional
transition metal carbonitride and in-situ
fiber-forming
polymer; through multi-component and closed segmented baking, the present application realizes the synchronous improvement of the
conductivity and
mechanical strength of the electrode paste while optimizing the aggregate accumulation, strengthening the
interface bonding, constructing the conductive network and three-dimensional
toughening structure, and the obtained product has the characteristics of low resistivity,
high pressure strength and low electrode consumption, and is suitable for self-baking electrodes of ore
smelting furnaces, and reduces the
energy consumption and cost while ensuring high performance.
