Abstract

The present invention belongs to the technical field of a conductive material, solves the problems that conventional conductive paper is large in thickness and hardness, low in tear strength and easy to tear, the service life is reduced, conductive performance is affected, and the like, and provides a plasticizing carbon paper softening processing method and softening composite conductive carbon paper prepared by the method. Conductive paper is prepared by wet molding, hydrophobic SBR styrene-butadiene rubber is prepared, and the conductive paper is plasticizing by the styrene-butadiene rubber. The method is simple, and suitable for industrial production; the conductive paper is ultra-thin, loose, soften and high in tear strength, the service life is increased, thermal conductivity is uniform, power stability, electrical conductivity is stable, temperature is kept stable, the indoor can be evenly heated, price is low, the service life is long, power consumption is low, the product is waterproof, fire retardant, and small in space occupation, can be freely wound, can be made into invisibly-heated walls, floors and furniture, can be used in insulation works, belongs to an energy saving, environmental-friendly, safe, easy-to-maintain new generation electric heating product, and is convenient to transport, transportation-cost-saving and durable.

Description

technical field [0001] The invention belongs to the technical field of conductive material production, and in particular relates to a softening treatment method for plasticized carbon paper and the prepared softened composite conductive carbon paper. Background technique [0002] Conductive paper is a kind of conductive functional paper, which can be widely used in anti-static packaging, electromagnetic shielding, surface heating, heat-resistant and flame-retardant, new energy, electrochemistry, biomedicine and other materials. Carbon fiber conductive paper is obtained by fully dispersing carbon fiber and other fibers or powder materials in a solvent, and drying them into paper. In order to make the fibers interweave more fully, organic compounds, such as polyvinyl alcohol, polyimide and other binders and cationic reinforcing agents, are usually added to increase the bonding force between fibers; at the same time, the content of carbon fibers can also be adjusted at Adjusta...
