1. A wooden multilayer glued electric heating plate is characterized in that a wooden veneer layer, a first gluing layer, a coating layer, a conductive substrate layer, a coating layer, a second gluing layer and a wooden veneer layer are sequentially arranged on the wooden multilayer glued electric heating plate from bottom to top, wherein the conductive substrate layer comprises conductive copper slurry and carbon crystal slurry, and is connected with a temperature sensor and a full-automatic temperature regulator through a power line;

  • the first cementing layer is a water-based adhesive composition, and the thickness of the first cementing layer is 7-12 mm;

    the second cementing layer is a water-based adhesive composition, and the thickness of the second cementing layer is 5-10 mm;

    the coating layer is a water-based flame-retardant coating composition;

    the aqueous flame retardant coating composition comprises;

    20-30 parts of modified argil powder10-20 parts of animal skin glue50-65 parts of water;

    the preparation method of the modified argil powder comprises the following steps;

    (1) grinding argil powder, sieving, screening argil powder with the particle size of 300-400 meshes, and drying at 120 ℃

    for 2 hours;

    (2) adding ethanol, a borate coupling agent, castor oil phosphate and a betaine surfactant into the argil powder treated in the step (1), heating to 85 ℃

    , preserving heat for 1h, cooling to room temperature, filtering, and drying under reduced pressure at 80 ℃

    for 10 h;

    the mass ratio of the borate coupling agent to the ethanol is 30;

    100, wherein the mass ratio of the argil powder to the borate coupling agent is 1;

    0.03, wherein the mass ratio of the castor oil phosphate ester surfactant, the betaine surfactant and the argil powder in the modified argil powder is 0.03;

    0.08;
