1. a preparation method for water-based high performance water proof moisture-penetrating coating fabric, comprises the steps:

  • (1) preparation of primary coat adhesive;

    by the thickener of the water cross-linking agent of the water-based foam stabilizer of the water-based pore former of the aqueous polyurethane of 88~

    93 weight portions, 5~

    8 weight portions, 1~

    2 weight portion, 1~

    2 weight portion and 1~

    2 weight portion, adopt shear mixer to stir 10~

    40min, through mechanical foaming, form bubble ratio at the micro-nano hole coating adhesive between 1;

    2 to 1;

    6 again, i.e. primary coat adhesive;

    (2) preparation of face coating adhesive;

    by the thickener of the water cross-linking agent of the water-based foam stabilizer of the water-based pore former of the acrysol of 88~

    93 weight portions, 5~

    8 weight portions, 1~

    2 weight portion, 1~

    2 weight portion and 1~

    2 weight portion, adopt shear mixer to stir 10~

    40min, through mechanical foaming, form bubble ratio at the micro-nano hole coating adhesive between 1;

    2 to 1;

    6 again, i.e. face coating adhesive;

    (3) preparation of coated fabric;

    base cloth is carried out to press polish arrangement, after arranging, fabric face is smooth or occur fine and closely woven oblique line, then primary coat adhesive is coated with and is scraped on base cloth, at 100~

    120 ℃

    of prebake 30s, form primer, again face coating adhesive is coated with and is scraped on primer, at 100~

    120 ℃

    of prebake 30s, then at 160~

    170 ℃

    , bake 30s and form face glue, the fabric after finally painting being scraped carries out rear press polish and clot.
