The invention relates to a lightweight interior material for an automobile rear cover. The interior material sequentially comprises a surface carpet (1) and a glass fiber plate (2) from top to bottom,wherein the thickness ratio of the surface carpet (1) to the glass fiber plate (2) is (4-8): 1. The preparation method comprises the steps of (1) processing and molding the glass fiber plate (2), specifically, sewing one surface of a glass fiber layer (22) with a PE adhesive layer by adopting a needling compound process, and sewing the other surface with a spunlace non-woven fabric (23); and (2)carrying out hot press molding on the surface carpet (1) and the glass fiber plate (2) to finally obtain the lightweight interior material for the automobile rear cover. Compared with the prior art, the lightweight interior material has the advantages of favorable mechanical properties, low VOC emission and the like.
