The invention provides an automobile roof material and a preparation method thereof. The preparation method comprises the following step: subjecting a roof base material and a knitted composite fabricto lamination and then to aftertreatment so as to obtain the automobile roof material, wherein the temperature of an upper mold for lamination is 95-115 DEG C, and the temperature of a lower mold forlamination is 40-90 DEG C. The automobile roof material prepared by using the preparation method provided by the invention has relatively excellent appearance and is free of defects such as bubblingand corrugation on the surface, and a preparation rejection rate can be greatly reduced; and meanwhile, the automobile roof material provided by the invention has the advantages of good sound absorption and heat insulation performances, is low in VOC content, and can meet application requirements.

    本发明提供了一种汽车顶蓬材料及其制备方法,所述制备方法包括如下步骤:将顶蓬基材和针织复合面料贴合、后处理,得到所述汽车顶蓬材料;其中,所述贴合的上模温度为95‑115℃,下模温度为40‑90℃。本发明提供的制备方法制备得到的汽车顶蓬材料具有较优异的外观,外观无鼓泡、无波纹等瑕疵,可以大幅度较少制备报废率;同时本发明提供的汽车顶蓬材料具有较好的吸音隔热的优点,且其VOC含量较低,能够满足应用要求。
