The invention provides a wicker curing agent and a preparation method thereof. The wicker curing agent mainly comprises polyacrylamide, methylbenzene, glycerol, liquid-state low-molecular-weight polyamide, ethylene thiourea, epoxy resin, tetramethylammonium thiuram tetrasulfide, polylactic acid, calcined kaoline, epoxy chloropropane, pullulan, nanometer silicon dioxide, zinc stearate, carbon black, ethyl silicon oil, calcium carbonate, glutaraldehyde, octadecanol, chloromethyloxirane, silica gel vulcanized agents, modified epoxy resin, isoamyl alcohol, isobutyl alcohol, castor oil polyoxylethylene ether, sodium dodecylbenzene sulfonate, ash, urea, potassium chloride, sucrose, peanuts, dried mushroom, forage, fresh milk, cold water, boiled water, rhubarb, magnoliae officinalis cortex, fructus aurantii, titanium dioxide, radix aucklandiae, popcorns, maltose, pitted red dates, talcum powder and ginger juice. A reinforcing agent prepared through the method is good in reinforcing effect, free of corrosion and capable of enhancing the strength and toughness of softened parts.
