NOVELTY - Preparing two-component dry process carbon paper, comprises stirring mesophase pitch A and component B containing mesophase pitch C, placing in two spinning machines evenly and spraying out continuous spinning at a certain speed and laying them on the mesh belt that can adjust the temperature and move to form continuous three-dimensional layer of mesophase asphalt that overlaps each other, rolling flat-laid mesophase pitch fibers by a temperature-adjustable pressure roller to form three-dimensional laminate of mesophase pitch fibers that is formed to overlap, subjecting mesophase pitch fiber layup to pre-oxidation heat treatment under protective atmosphere to obtain three-dimensional mesophase pitch phase pitch fiber layup having uniform cross-linking and overlapping, pre-oxidizing mesophase pitch layer after heat treatment, and carbonizing in vacuum furnace to form carbon paper. USE - The method is useful for preparing two-component dry process carbon paper. ADVANTAGE - The carbon paper improves the porosity.
