Method and device for producing carbon paper
A method for producing carbon paper, including: 1) employing a polyacrylonitrile-based carbon fiber as a reinforcing material, a phenolic resin or epoxy resin as a bonding agent, and molding and preparing the carbon fiber into a carbon fiber blank by a dry paper-making method; and 2) stacking and putting a product obtained in step 1) into a reaction furnace for deposition process, the pressure in the reaction furnace being 1 kPa to 1 atmosphere, with methane, propene, or liquefied petroleum gas as a carbon source gas, nitrogen or argon gas as a diluent gas, the concentration of the carbon source gas being 5-100%, the gas flow rate being 0.1-5 L/min, and the temperature in the reaction furnace being controlled at between 800° C. and 1100° C., and the time of deposition process being 1-5 h.
