NOVELTY - A graphene-reinforced geogrid contains 2-3 pts. wt. barium metaborate, 5-7 pts. wt. graphene oxide, 40-50 pts. wt. para-hydroxybenzoic acid, 10-17 pts. wt. acetic anhydride, 0.08-0.1 pt. wt. zinc acetate, 20-30 pts. wt. 6-hydroxy-2-naphthoic acid, 180-200 pts. wt. high-density polyethylene, 1-2 pts. wt. isopropyl palmitate, 0.5-1 pts. wt. ethoxylated alkylphenol ammonium sulfate, 1.6-2 pts. wt. stannous chloride, 1-2 pts. wt. polyglycerol fatty acid ester, 0.4-1 pts. wt. polyimide, 3-4 pts. wt. polyethylene glycol adipate, and 0.1-0.2 pt. wt. nickel sulfamate. USE - Graphene-reinforced geogrid (claimed). ADVANTAGE - The graphene-reinforced geogrid has excellent surface strength, pressure resistance, leakage resistance and prolonged service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-reinforced geogrid, which involves adding nickel sulfamate to para-hydroxybenzoic acid, uniformly mixing, stirring the mixture at 50-60 degrees C, adding ethoxylated alkylphenol ammonium sulfate to the mixture and then heat preserving for 3-4 minutes, adding acetic anhydride to the mixture and then mixing, adding sulfuric acid and 6-hydroxy-2-naphthoic acid to the mixture and then stirring at 120-130 degrees C, adding stannous chloride to the mixture and then stirring, adding isopropyl palmitate and anhydrous ethanol to the mixture and then uniformly stirring, adding polyglycerol fatty acid ester, graphene oxide, anhydrous ethanol and acetylated monomer to the mixture and then preheating for 6-10 minutes, adding remaining raw materials to the mixture and then uniformly stirring, placing the mixture in an extruder and then melting, and stretching.
