[0024] refer to figure 1 , the preparation method of above-mentioned corrugated box that the present invention proposes uses antistatic heat-resistant coating, comprises the steps:
[0025] S1. Add modified phenolic resin, urea-formaldehyde resin, acrylic resin and deionized water into the mixer, and stir at a stirring speed of 180-220r / min for 25-40min to obtain material a;
[0026] S2. Add graphite, carbon nanotubes, carbon fibers, bentonite, fly ash, calcium silicate, titanium dioxide, tin oxide, potassium chloride, cryolite, sodium fluoroborate, anhydrous sodium sulfite, magnesium stearate to material a , silane coupling agent, amide curing agent and dimethylformamide, stirred at a stirring speed of 450-550r / min for 50-70min, filtered with a mesh ≥ 120 mesh, and packed into barrels to obtain antistatic antistatic hot paint.
