The invention provides an automobile interior ceiling composite material. The automobile interior ceiling composite material comprises an organic fiber fabric layer, the hot melt adhesive layer is compounded on the organic fiber fabric layer; the thermoplastic foam layer is compounded on the hot melt adhesive layer; the thermoplastic foam comprises one or more of polypropylene foam, polyethylene glycol terephthalate foam and polyethylene foam; the hot melt adhesive layer is compounded on the thermoplastic foam layer; and the organic fiber fabric layer is compounded on the thermoplastic foam layer. The full-thermoplastic material is adopted, so that on the premise that the performance of the ceiling is guaranteed, the ceiling is more environmentally friendly, and later recycling and reusing are facilitated; the cold press molding is performed after heating, so that the process is more energy-saving; meanwhile, the high-performance thermoplastic foam material is adopted, so that the ceiling is lighter in weight and lower in manufacturing cost under the condition that the performance of the ceiling is not reduced, and the composite material is an interior ceiling composite material which is free of formaldehyde, low in VOC, low in odor, light in weight, recyclable and low in manufacturing cost.
本发明提供了一种汽车内饰顶棚复合材料,包括有机纤维织物面料层;复合在所述有机纤维织物面料层上的热熔胶层;复合在所述热熔胶层上的热塑性泡沫层;所述热塑性泡沫包括聚丙烯泡沫、聚对苯二甲酸乙二醇酯泡沫和聚乙烯泡沫中的一种或多种;复合在所述热塑性泡沫层上的热熔胶层;复合在所述热塑性泡沫层上的有机纤维织物面料层。本发明采用全热塑性材料,在保证顶棚的性能前提下,更加环保,便于后期回收再利用;而且先进行加热再冷压成型,工艺更加节能;同时采用高性能热塑性泡沫材料,使得顶棚在性能不减的保证下,顶棚更加轻量化,制造成本更低,是一种无醛、低VOC、低气味、轻量化、可回收利用、低制造成本的内饰顶棚复合材料。
