Abstract

The invention provides an environmentally-friendly automotive trim composite material and a preparation method thereof. The automotive trim composite material comprises a surface layer, a foaming layer, a hot melt glue layer and a skeleton structure layer, wherein the surface layer is a TPU (Thermoplastic Polyurethanes) film layer, a TPO (Thermoplastic Polyolefin) film layer, a PU (Poly Urethane) film layer, a PP (Propene Polymer) film layer or a genuine leather layer; the foaming layer is a PP foaming layer, a PPF foaming layer, a PU foaming layer or a PE (Poly Ethylene) foaming layer; the hot melt glue layer is a TPU hot melt glue layer, an EVA (Ethylene-vinyl Acetate Copolymer) hot melt glue layer, a PE hot melt glue layer, a PA (Poly A) hot melt glue layer or other hot melt glue layers; the skeleton structure layer is made of a glass fiber modified PP composite material, a carbon fiber modified PP composite material, or an ABS (Acrylonitrile Butadiene Styrene) modified PP composite material. According to the environmentally-friendly automotive trim composite material and the preparation method thereof provided by the invention, the surface layer with the foaming layer is glued with a skeleton structure through an environmentally-friendly hot melt glue, so that the gluing degree is good, the rejection rate is low, the product forming quality is effectively ensured, and the manpower is saved; the product is wear-resisting, high in tearing strength and dimensional stability, not easy to strip, attractive in appearance, and environmentally-friendly in production process without pollution; the product can be recycled.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an automobile interior composite material and a preparation method thereof, in particular to an environment-friendly automobile interior composite material and a preparation method thereof. Background technique [0002] Dashboards are an important part of car interiors. In recent years, as technology has continued to advance, more operational functions have been integrated into the dashboard. Obviously, in order to ensure that the various instruments and parts supported can work normally under high-speed driving and vibration conditions, the instrument panel must have sufficient rigidity, and in order to reduce the impact of external forces on the front and co-pilot in the event of an accident, the instrument panel is also required Has good energy absorption. At the same time, due to the requirements of comfort and aesthetics, people pay more and more attention to the f...
