The invention relates to the technical field of automotive trim, in particular to a lightweight automotive door trim panel and a preparation process. The light-weight automobile door interior trimming panel comprises a plurality of framework bodies, the multiple framework bodies are mutually connected to form the automobile door interior trimming panel, and each framework body comprises an EPP foaming structure and a surface decoration layer attached to the EPP foaming structure; the EPP foaming structure is located on the side, facing the interior of the automobile, of the framework body and used for providing structural support; and the surface decoration layer is located on the side, facing the interior of the automobile, of the EPP foaming structure and used for improving the wear resistance and durability of the automobile interior. According to the invention, improvement and upgrading of an existing automobile door interior trim panel are completed, so that the automobile door interior trim panel is lighter under the condition that original functions are not changed, the investment cost of a mold can be greatly reduced, and the technical problem that the automobile door interior trim panel assembly in the prior art is poor in energy conservation, emission reduction and energy efficiency improvement effects due to high density and heavy dead weight is effectively solved.

    本发明涉及汽车内饰技术领域,尤其涉及一种轻量化汽车门内饰板及制备工艺。轻量化汽车门内饰板包括:骨架主体,其数量为多个,多个骨架主体相互连接以形成汽车门内饰板,骨架主体包括EPP发泡结构和与EPP发泡结构贴合的表面装饰层;EPP发泡结构,其位于骨架主体的朝向汽车内部的一侧,以用于提供结构支撑;表面装饰层,其位于EPP发泡结构的朝向汽车内部的一侧,以用于提升汽车内饰的耐磨性与耐久性。本发明完成了对现有汽车门内饰板的改良升级,使得其在保证原有功能不变的情况下自重更轻,且可大大降低模具的投资成本,有效解决了现有技术中汽车门内饰板总成的密度高、自重重,导致其节能减排与提高能效的效果差的技术问题。
