The invention discloses an antioxidant geocell master batch which comprises the following raw materials in parts by weight: 121-130 parts of high density polyethylene, 1-3 parts of polyurethane, 2-3 parts of calcium hydrophosphate, 2-3 parts of silicon carbide, 1-2 parts of potassium tetraborate, 0.3-0.5 part of ammonium metavanadate, 0.4-1 part of tetradecanedioic acid, 10-13 parts of graphite powder, 0.1-0.4 part of tung oil, 1-3 parts of polyving alcohol, 0.5-2 parts of sodium carboxymethylcellulose, 0.6-1 part of thiodipropionic diglycerol trilaurate, 10-12 parts of blast furnace slag and 2-3 parts of rare earth additive. According to the antioxidant geocell master batch disclosed by the invention, high-strength boron carbide, attapulgite and rare earth elements are fully mixed by the added rare earth additive; the mixture is matched with calcium acetate as a preservative and polyvinylpyrrolidone as a stabilizer; under the surface treatment action of a silane coupling agent, the formed additive has the advantages of good surface strength, toughness, wear resistance and corrosion resistance as well as good stability; the comprehensive quality of the mast batch can be effectively improved, and the adaptability to soil and the resistance to the outside pressure are improved.
