The invention discloses a recycled modified material of a waste drip-irrigation tape and a preparation method thereof. The recycled modified material comprises the following components: a drip-irrigation tape crushed material, high-density polyethylene 2480, a compatibilizer, an elastomer, polyethylene wax, glycerol and light calcium carbonate. The recycled modified material of the waste drip-irrigation tape is prepared from the following raw material components in parts by mass: 50 to 100 parts of the drip-irrigation tape crushed material, 10 to 30 parts of the high-density polyethylene 2480, 0.5 to 2 parts of the compatibilizer, 0.2 to 1 part of the elastomer, 0.3 to 1 part of the polyethylene wax, 2 to 3 parts of glycerol and 4 to 6 parts of the light calcium carbonate. The recycled modified material of the drip-irrigation tape is prepared through the following steps: recycling the waste drip-irrigation tape, and carrying out cutting, cleaning, air drying, crushing, melting, plasticizing and extrusion.
