Abstract

The invention belongs to the technical field of papermaking and in particular relates to nanofiber carbon black conductive paper and a preparation method thereof. The nanofiber carbon black conductive paper is prepared from the following raw materials: bleached needle leaf pulp, bleached broad leaf pulp, mineral fillers, nanofiber additives, carbon black, a dispersing agent, a wet strength agent and a dry strength agent. The nanofiber carbon black conductive paper disclosed by the invention can meet use of the traditional conductive paper and can also serve as battery electrode coating paper, so that the application range of the conductive paper is widened. The product has the advantages of high uniformity, high covering property, high mechanical strength, excellent conductive performance and high chemical stability.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a nanofiber carbon black conductive paper and a preparation method thereof. Background technique [0002] Conductive paper is an important functional paper variety, which plays an important role in the field of electronic products. The traditional conductive paper has the disadvantages of low paper conductivity, metal is easy to be oxidized and the conductivity drops quickly, and the coating is easy to fall off, which makes its conductivity and stability low, and the shielding performance is very poor, which limits the conductivity. Application fields of paper. Therefore, we focus on researching a surface paper that can effectively conduct static electricity as an electrostatic sticker. The higher the electrical conductivity of the paper required by the electrostatic sticker, the better; The smooth discharge of the product. Contents of the invention [0003] ...
