The invention discloses a degradable plastic product and its preparation method. The degradable plastic material comprises: 60-100 parts of PBAT, 3-5 parts of pretreated corn gluten meal, 40-60 parts of calcium carbonate, 1-2 parts of plasticizer, 1-2 parts of coupling agent, 5-10 parts of absolute ethanol, and 0.5-1 part of heat stabilizer. The preparation process: Spray plasticizer onto pretreated corn gluten meal for blending and sealed curing to obtain plasticized corn gluten meal; Mix coupling agent with absolute ethanol evenly and spray onto calcium carbonate and plasticized corn gluten meal for surface modification; Blend PBAT, heat stabilizer and modified fillers to form a compound; extrude and granulate in a twin-screw extruder, followed by molding to obtain finished products. The prepared degradable plastic products have high mechanical strength, thermal stability and hydrophobicity.
