DETAILED DESCRIPTION - A rosin-containing geogrid comprises 107-120 pts. wt. high density polypropylene, 8-10 pts. wt. carboxylated graphene powder, 0.1-0.2 pts. wt. cadmium stearate, 6-10 pts. wt. maleic anhydride-grafted polypropylene, 2-3 pts. wt. rosin, 1-2 pts. wt. lanolin, 0.1-0.3 pts. wt. potassium bromate, 1-1.6 pts. wt. methylenedioxy naphthalene sulfonate, 0.1-0.4 pts. wt. antioxidant butylated hydroxytoluene, 2-3 pts. wt. bamboo charcoal powder, 0.2-0.4 pts. wt. hexafluoroacetylacetonato, 7-10 pts. wt. blast furnace slag, 2-3 pts. wt. rare earth auxiliary agent, and 1-2 pts. wt. sodium silicate. The rare earth auxiliary agent comprises 30-40 pts. wt. boron carbide, 5-6 pts. wt. rare earth chloride, 10-18 pts. wt. attapulgite, 10-15 pts. wt. silicic acid, 2-3 pts. wt. aluminum tripolyphosphate, 1-2 pts. wt. calcium acetate, 0.8-1 pt. wt. phosphite, 2-3 pts. wt. potassium carbonate, 0.3-0.4 pts. wt. polyvinylpyrrolidone, and 0.1-0.2 pts. wt. glycidoxypropyltrimethoxysilane (silane coupling agent KH560). The rare earth auxiliary agent is prepared by mixing calcium acetate with attapulgite, milling, adding phosphite, stirring to 40-50 degrees C for 6-10 minutes to obtain mixture; adding aluminum tripolyphosphate with 20-30 times water, stirring to 70-80 degrees C for 10-20 minutes, adding into mixture, adding silicic acid, stirring to room temperature, dehydration, drying, grinding into fine powder, and mixing with boron carbide; and adding rare earth chloride with 20-30 times water, adding to obtained powder, mixing with potassium carbonate, stirring to 80-90 degrees C for 3-5 minutes, adding polyvinylpyrrolidone and silane coupling agent KH560, mixing, reducing temperature to 50-60 degrees C, standing for standing 1-2 hours, dehydrating, and calcining to 150-200 degrees C for 30-40 minutes. The rare earth chloride is cerium chloride and/or lanthanum chloride mixture. An INDEPENDENT CLAIM is included for preparation of rosin-containing geogrid comprising heating rosin to soften, adding lanolin, mixing, adding maleic anhydride-grafted polypropylene, and mixing to 100-110 degrees C for 6-10 minutes to obtain rosin mixture; drying blast furnace slag, adding with bamboo charcoal powder and cadmium stearate, and milling powder; adding sodium silicate with 3-4 times water, stirring, and adding methylenedioxy naphthalene sulfonate while stirring; and mixing obtained products, stirring, adding carboxylated graphene powder, dispersing at 100-200 revolutions/minute for 6-10 minutes, adding remaining raw materials, drying, melt-extruding through screw extruder, pressing into sheets, punching, and stretching.
