Abstract

The invention belongs to the technical field of conductive material manufacturing, and provides a method for reinforcing conductive carbon paper, and a hydrolysis-resistant conductive carbon paper prepared therethrough in order to solve a problem that poor waterproof property and low moisture absorption property of existing conductive papers even having improved tear strength are bad for the use of the existing conductive papers on the ground or in a humid environment, shorten the life and affect the electrical conduction property. The method comprises the following steps: wet molding of a conductive paper, preparation of a polyvinyl alcohol latex, and reinforcing the polyvinyl alcohol latex with the conductive paper. The temperature of the conductive carbon paper can be easily controlled,the temperature resistance is improved, the lowest temperature reaches 50 DEG C or above, and the application field of the conductive carbon paper is broadened. The improvement of the hydrolysis resistance of the conductive paper makes the product have the advantages of good waterproof property, good flame retardant property and small occupied space and realize large-area low temperature radiantheat. The paper can be wound freely, can be easily pasted and compounded on a wall and a flat utensil, and is compounded in a wood floor to form a self-heating composite floor, is moisture-proof and waterproof, and can be used in a water immersion or humid environment.

Description

technical field [0001] The invention belongs to the technical field of conductive material production, and in particular relates to a method for strengthening conductive carbon paper and the prepared hydrolysis-resistant 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 or styrene-butadiene latex and cationic reinforcing agents are usually added to increase the bonding force between fibers; The content can also be adjusted within a wide range. Carbon fiber conducti...
