The invention discloses an anti-corrosion material for refrigerator inner liners and its preparation method, belonging to the technical field of refrigerator liner materials. The raw materials include the following parts by weight: 40‑55 parts of high-impact polystyrene, 30‑50 parts of polyethylene, 10‑15 parts of modified calcium carbonate, 6‑10 parts of compatibilizer, 0.1‑3 parts of lubricant, and 0.05‑1 part of antioxidant. The preparation steps are as follows: S1. Weigh the raw materials in proportion, add high-impact polystyrene, polyethylene, modified calcium carbonate, compatibilizer, lubricant and antioxidant into a mixer and blend uniformly to obtain a mixed material; S2. Feed the mixture into a twin-screw extruder for extrusion, cooling and granulation to prepare the anti-corrosion material. The obtained material features excellent corrosion resistance, low-temperature resistance, superior mechanical properties and high melt strength. When applied to refrigerator inner liners, it delivers outstanding anti-corrosion performance, making the liners sturdy, durable and crack-resistant.
