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.

    本发明涉及一种汽车后盖用轻量化内饰材料,该内饰材料从上到下依次包括:表面地毯(1)和玻纤板(2),所述的表面地毯(1)与玻纤板(2)的厚度之比为(4‑8):1,其制备方法包括以下步骤:(1)玻纤板(2)的加工成型:采用针刺复合工艺,将玻纤层(22)一面缝合PE粘合层(21),另一面缝合水刺无纺布(23);(2)表面地毯(1)与玻纤板(2)的热压成型,最终得到汽车后盖用轻量化内饰材料。与现有技术相比,本发明具有力学性能良好、VOC散发量少等优点。
