1. , a kind of preparation method of full p-aramid fiber amide paper is characterized in that comprising following concrete steps:

  • (1) add counterpoint type aramid staple fiber, counterpoint type aramid pulp, dispersing aid in water, raw material obtains slurry after disperseing;

    (2) approach flow moulding;

    (3) dehydration, squeezing, drying;

    (4) with on the even impregnation steps of counterpoint type aromatic polyamides solution (3) the gained fibrous paper;

    (5) step (4) is handled the fibrous paper that obtains and carry out hot pressing or cold pressing treatment;

    (6) with step (5) gained fibrous paper through the solidification liquid moulding;

    (7) with step (6) gained fibrous paper through leacheate flush away solvent;

    (8) dehydration, squeezing, drying;

    Used each composition weight umber is as follows;

    Water 100Counterpoint type aramid staple fiber 0-90Counterpoint type aramid pulp 0-90Dispersing aid 0.0001-1Counterpoint type aromatic polyamides solution 5-95Wherein counterpoint type aramid staple fiber, counterpoint type aramid pulp, counterpoint type aromatic polyamides solution summation are 100 parts of weight;

    Counterpoint type aromatic polyamides solution concentration is the 0-25% quality, and solvent is one or more in organic solvent, acid, inorganic salts, the water.
