1. the Preparation Method of the poroid coal ash heat-preservation material of honeycomb, it is characterized in that, comprise the following steps:

  • the surface modification of flyash;

    get 1000 weight part 400 purpose flyash standby, then after the tetramethoxy-silicane of getting 50~

    100 weight parts such as uses at the dehydrated alcohol dilution of weight, evenly be added drop-wise to flyash in well-beaten situation in, treat that flyash is fully flooded abundant drying for standby in the loft drier that is placed on 60~

    80 ℃

    ;

    The configuration of flyash-epoxy resin slurry;

    in mixing vessel, 1000 weight part epoxy resin fully are dissolved in 100~

    200 weight part acetone, then add 200~

    300 weight parts of polyamide 650, add the 400 order flyash of 500 weight parts after surface modification after stirring, stir rear standby;

    The moulding of the poroid coal ash heat-preservation material of honeycomb;

    in the flyash that configures-epoxy resin slurry injection moulding mould, mould is placed in the loft drier of 130~

    170 ℃

    heats stopped heating after 10~

    40min, after case naturally cooling to be dried, product is taken out from mould namely get the poroid coal ash heat-preservation material of honeycomb.
