The invention provides a preparation method of ABS sheets, inner liners, door liners and refrigeration equipment. The preparation method of ABS sheets includes the following steps: weighing components in parts by weight: 30–50 parts of acrylonitrile, 5–10 parts of butadiene, 15–30 parts of acrylate, 30–50 parts of styrene and 2–5 parts of stabilizer; adding the above materials into a kneader for mixing and copolymerization; feeding the copolymerized mixture into an extruder to prepare ABS pellets; drying the ABS pellets; and performing extrusion molding through an extruder to obtain ABS sheets. The formula increases the content of corrosion-resistant acrylonitrile and reduces the content of unstable butadiene containing double bonds. Meanwhile, the added acrylate components improve the environmental stress cracking resistance (ESC) and corrosion resistance of ABS sheets. It avoids corrosion and cracking of inner liners and door liners made of ABS sheets after contact with LBA foaming agents, and prolongs their service life, with simple processes and low cost.
