Abstract

The invention discloses a method for preparing composite automotive interior trim parts, which is composed of a polymer-based hemp fiber composite material as a substrate, a decorative layer on the outer surface of the substrate, and a plastic insert on the inner surface of the substrate , the preparation method of which comprises using polymer-based hemp fiber composite felt as a raw material, heating at 200°C for 150 seconds to a plasticized state, and obtaining the substrate by compression molding; spraying the outer surface of the substrate with a two-component Polyurethane glue; heating the substrate prepared above to the activated state of the surface colloid, molding and compounding the surface finish layer on the substrate; bonding the plastic insert on the inner side of the substrate by hot-melt adhesive, that is Obtain composite automotive interior panel parts products.

Description

technical field [0001] The invention relates to a method for preparing an automobile door trim panel, in particular to a method for preparing an automobile door trim panel by using a polymer natural fiber composite material. Background technique [0002] At present, with the weight reduction of automobiles, the requirements for the performance of the materials used are getting higher and higher. Composite materials for automotive interior parts are developing in the direction of sound absorption, heat insulation, lightweight, high strength, environmental protection, and recyclability. Natural fiber materials are good materials for heat insulation and sound insulation, especially as filling and reinforcing materials for polymer materials. Due to their light weight and low cost, they have been widely used in the manufacturing of automotive interior parts. There is an increasing demand for polymer natural fiber material composites in the automotive interior manufacturing indus...
