The invention belongs to the technical field of automobile decoration inner plates, and provides a composite automobile inner plate skin improved structure which comprises a PUR coating, a PVC layer, a PVC foaming layer and a composite woven fabric layer, a PUR coating back glue layer is arranged between the PVC foaming layer and the composite woven fabric layer, the PVC layer is located between the PUR coating and the PVC foaming layer, and the PVC foaming layer is located between the PUR coating and the PVC foaming layer. The whole formed by the PUR coating, the PVC layer and the PVC foaming layer is adhered to the composite woven fabric layer through the PUR coating gum layer. The invention has the advantages that the PVC layer, the PVC foaming layer and the composite woven fabric layer are utilized, so that the skin is not easy to collapse, the touch feeling is good, the environmental pollution is small, and in addition, the tensile strength is improved by utilizing the polyester foam layer and is 165N; the elongation at break is 180, the odor of the whole composite automobile inner plate skin is low (grade 3.7), and a good technical effect is achieved.
本发明属于汽车装饰内板技术领域,提供了一种复合汽车内板蒙皮改进结构,包括有PUR涂层、PVC层、PVC发泡层以及复合织布面料层,PVC发泡层与复合织布面料层之间具有PUR涂层背胶层,PVC层位于PUR涂层与PVC发泡层之间,PUR涂层、PVC层以及PVC发泡层组成的整体通过PUR涂层背胶层粘贴到复合织布面料层上。本发明的优点在于利用PVC层、PVC发泡层以及复合织布面料层,可以表皮不易塌陷、触感好,且环境污染小,另外利用聚酯泡棉层提升了拉伸强度,拉伸强度165N;断裂伸长率180,整个复合汽车内板蒙皮气味低(3.7级),取得了较好的技术效果。
