The invention relates to a precipitation-resistant resin layer for artificial leather and a preparation method thereof, artificial leather and a preparation method thereof, and an automobile. The resin layer is prepared from a resin layer raw material; the resin layer is prepared from the following raw materials in parts by weight: 100 parts of PVC powder and CPE powder, 30-60 parts of migration-resistant plasticizer and 2-4 parts of stabilizer; wherein the mass ratio of the PVC powder to the CPE powder is (60-95): (5-40); the CPE powder contains an external lubricating substance, and the proportion of the external lubricating substance in the CPE powder is 2%-4%; the migration-resistant plasticizer comprises one or a combination of more of a trimellitic plasticizer, a polyester plasticizer and a citric acid plasticizer. The precipitation resistance and the low-temperature bending resistance of the resin layer or the artificial leather can be improved.
