The invention discloses a preparation method of an automobile roof composite fabric with a low VOC value. The preparation method comprises the following steps: S101, obtaining preparation raw materials of a polyester gray fabric, a spunlace non-woven fabric and a polyurethane sponge with target specifications; s102, performing low-VOC value treatment with the VOC value smaller than a preset value on the polyester gray fabric by using a combined process of washing, dyeing and high-temperature setting treatment to obtain a polyester fabric; s103, adding an antioxidant into the preparation raw materials of the polyurethane sponge to prepare the polyurethane sponge; s104, compounding and bonding a polyester fabric and a spunlace non-woven fabric to the two surfaces of the polyurethane sponge respectively by adopting a flame compounding machine to prepare a ceiling fabric; and S105, carrying out baking process treatment on the off-line ceiling composite fabric by using a drying room. Therefore, the problems that in the prior art, low-VOC-value ceiling composite fabric process equipment is complex to maintain, fabric is prone to being damaged, the production period is long, and the VOC performance problem improving effect is poor are solved.

    本发明公开了一种低VOC值的汽车顶棚复合面料的制备方法,包括S101:获取目标规格的涤纶坯布、水刺无纺布和聚氨酯海绵的制备原料;S102:利用水洗、染色和高温定型处理组合工艺对涤纶坯布进行VOC值小于预设值的低VOC值处理,得到涤纶面料;S103:在聚氨酯海绵的制备原料中添加抗氧化剂制备聚氨酯海绵;S104:采用火焰复合机将涤纶面料和水刺无纺布分别复合粘接于聚氨酯海绵的两面,制备得到顶棚面料;S105:利用烘房对下线的顶棚复合面料进行烘烤工艺处理。由此,解决了现有技术中低VOC值顶棚复合面料工艺设备维护复杂、易损伤面料、生产周期长和VOC性能问题改善效果差的问题。
