The invention provides a novel TPO skin environment-friendly automobile soft instrument board and a manufacturing method thereof, and belongs to the technical field of instrument boards for automobileinteriors, the novel TPO skin environment-friendly automobile soft instrument board sequentially comprises a skeleton layer, a middle buffer layer and a skin layer from inside to outside, wherein theskeleton layer is made of a glass fiber reinforced PP material, the middle buffer layer is made of a PET 3D mesh material with a three-dimensional mesh structure, and the surface layer is made of a TPO material with base cloth. In the aspect of material selection, TPO with low VOC volatilization and low odor is used as an instrument board skin, PET 3Dmesh with low VOC volatilization and low odoris used as an instrument board buffer layer material, and a glass fiber reinforced PP material is used as an instrument board framework. In the aspect of the manufacturing process, the environment-friendly soft instrument board is finally manufactured through design and implementation of a novel environment-friendly process. The VOC volatility of the final product is obviously reduced, the defectthat the smell of a traditional slush molding PVC surface layer and a PUR foam buffer layer is poor is overcome, and the environment-friendly and high-quality requirements of a main engine plant for interior trim parts are met.

    本发明提供了一种新型的TPO表皮环保型汽车软质仪表板及其制造方法,属于汽车内饰用仪表板技术领域,从里到外依次为骨架层、中间缓冲层和表皮层;所述骨架层为玻纤增强PP材料,中间缓冲层为立体网孔组织结构的PET 3D mesh材料,表皮层为带有基布的TPO材料。在材料选择方面,使用低VOC挥发和低气味的TPO为仪表板表皮,低VOC挥发和低气味的PET 3Dmesh为仪表板缓冲层材料,玻纤增强PP材料为仪表板骨架。在制造工艺方面,通过环保新工艺的设计实施,最终制得环保型软质仪表板。最终产品的VOC挥发性有了明显降低,解决了传统搪塑PVC表皮、PUR泡沫缓冲层气味差的缺点,符合主机厂对内饰零件的环保高品质要求。
