The invention discloses an automobile inner decorative fabric-regenerated foam compounded and pressed ceiling sheet material. An automobile inner decorative fabric layer is compounded on one side of a regenerated flame-retardant rubber-plastic foam layer to form a regenerated flame-retardant rubber-plastic foam automobile inner decorative fabric lamella; an adhesive layer is compounded on the regenerated flame-retardant rubber-plastic foam automobile inner decorative fabric lamella; and the sheet material is fixed on the ceiling of an automobile through the adhesive layer. A preparation method for the sheet material comprises the following steps: pressing the regenerated flame-retardant rubber-plastic foam layer and the automobile inner decorative fabric layer to prepare the regenerated flame-retardant rubber-plastic foam automobile inner decorative fabric lamella; and coating the regenerated flame-retardant rubber-plastic foam layer with glue of the adhesive layer so as to prepare the automobile inner decorative fabric-regenerated foam compounded and pressed ceiling sheet material. In usage of the sheet material, a protective layer is peeled off. Thus, the sheet material can cyclically utilize rubber-plastic foam, reduce environmental pollution and save resources and energy; and noise in the automobile can be reduced, and comfortableness in driving of the automobile can be improved.
