NOVELTY - An oxidation-resistant geogrid contains graphene oxide, para-hydroxybenzoic acid, acetic anhydride, zinc acetate, 6-hydroxy-2-naphthoic acid, high-density polyethylene, 2-bromo-4-methylphenol, lauric acid diethanolamide, ammonium molybdate, glycerol monostearate, N,N-diethylaniline, tris(2,4-ditert-butylphenyl) phosphite, dodecyl thiodipropionate, alkenyl succinic anhydride, and diacetone alcohol. USE - Oxidation-resistant geogrid (claimed). ADVANTAGE - The geogrid has excellent oxidation resistance, comprehensive performance and prolonged service life. DETAILED DESCRIPTION - An oxidation-resistant geogrid contains 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, 0.7-1 pts. wt. 2-bromo-4-methylphenol, 1-2 pts. wt. lauric acid diethanolamide, 2-3 pts. wt. ammonium molybdate, 1-2 pts. wt. glycerol monostearate, 0.3-1 pts. wt. N,N-diethylaniline, 0.6-1 pts. wt. tris(2,4-ditert-butylphenyl) phosphite, 0.1-0.4 pt. wt. dodecyl thiodipropionate, 1-2 pts. wt. alkenyl succinic anhydride, and 2-3 pts. wt. diacetone alcohol. An INDEPENDENT CLAIM is included for preparation of oxidation-resistant geogrid, which involves adding acetic anhydride to para-hydroxybenzoic acid, uniformly mixing, stirring at 138-140 degrees C for 10-15 minutes, adding lauric acid diethanolamide and deionized water to the mixture and then uniformly stirring, adding ammonium molybdate to the mixture and then heat preserving at 60-70 degrees C for 3-5 minutes, adding 6-hydroxy-2-naphthoic acid to the mixture and then reacting at 120-130 degrees C for 3-4 hours, filtering the mixture, adding acetylated monomer, diacetone alcohol and graphene oxide to the mixture and then stirring, adding glycerol monostearate to the mixture and then preheating at 80-90 degrees C for 3-5 minutes, adding remaining raw materials to the mixture and then uniformly stirring, placing the mixture in an extruder and then melting, and stretching.
