The invention relates to the field of non-woven fabric composite materials for automobile interiors, in particular to automobile roof composite cloth and a preparation process thereof. The automobile roof composite cloth is prepared by sequentially stacking a non-woven fabric layer, a polyurethane hot melt adhesive, a heat-insulating and flame-retardant layer, another polyurethane hot melt adhesive and an ultraviolet-proof layer and carrying out hot pressing, and the heat-insulating and flame-retardant layer comprises a composite glass fiber layer, a base cloth layer and a heat-insulating layer. The polyurethane hot melt adhesive is prepared from the following raw materials: an isocyanate substance, a hydroxyl substance, a flame retardant, a light screening agent, an organic solvent and a catalyst. The non-woven fabric layer, the heat-insulating and flame-retardant layer and the ultraviolet-proof layer of the automobile roof composite cloth are integrated through polyurethane hot-melt bonding, and all the layers cooperate with one another in function, so that the automobile roof composite cloth has excellent heat-insulating and flame-retardant performance.
本发明涉及汽车内饰用无纺布复合材料领域,特别是涉及一种汽车顶棚复合布及其制备工艺。其中,一种汽车顶棚复合布为由无纺布层、聚氨酯热熔胶、隔热阻燃层、聚氨酯热熔胶及防紫外线层依次层叠设置,经热压后制备得到,其中,隔热阻燃层包括复合玻纤层、基布层及隔热层,聚氨酯热熔胶的制备原料包括异氰酸物质、羟基物质、阻燃剂及光屏蔽剂、有机溶剂及催化剂;通过聚氨酯热熔粘结使得汽车顶棚复合布的无纺布层、隔热阻燃层及防紫外线层成为一个整体,各层功能上彼此协同,使得汽车顶棚复合布具有优异的隔热及阻燃性能。
