The invention discloses an automobile interior ceiling and a production method thereof, and belongs to the field of automotive interiors. The structure of the automobile interior ceiling is composed of a first non-woven fabric layer (1), a first glue blocking film layer (2), a first glass fiber mat layer (3), a first forming glue layer (4), a PU foam board layer (5), a second forming glue layer (6), a second glass fiber mat layer (7), a second glue blocking film layer (8), a second non-woven fabric layer (9), a glue film layer (10) and a fabric layer (11) from bottom to top in sequence. In the process of compounding the fabric, the hot melt adhesive film is used for replacing solvent adhesive or water-based adhesive for spraying, so that adhesive mist is prevented from being generated, the investment of adhesive spraying equipment is reduced, and the odor and VOC indexes of the product are better.
