Abstract

The invention relates to a multi-layer composite board, which consists of a PMMA layer, a transparent ABS layer and an ABS layer from top to bottom, and is compounded and formed through an extrusion process and a vacuum molding process to obtain a lightweight, spray-free, high weather resistance, and Scratch resistant automotive exterior composite panels. The automobile exterior decorative panel produced by the process of the present invention has very good mechanical properties, has the characteristics of light weight, spray-free, high weather resistance, scratch resistance, etc., and can be perfectly combined with the plate in the field of cars and commercial vehicles. Realize the requirements for lighter, more economical, and more environmentally friendly components such as hoods, roofs, and fenders.

Description

Technical field: [0001] The invention relates to the technical field of automotive decorative panels, in particular to a lightweight, spray-free, high weather-resistant, scratch-resistant automotive exterior composite panel, and also relates to an automotive exterior composite panel made of the automotive exterior composite panel. A trim panel, and a method for producing the automotive exterior trim panel. Background technique: [0002] Due to the diversity of lightweight and excellent formability designs, plastics currently account for about 10% of the total weight of automobile materials, and the ratio is increasing year by year. The scope of application has also expanded from interior fittings and exterior fittings to exterior fittings, and its use has gradually expanded. [0003] Especially due to severe environmental pollution and the sharp increase in the demand for automobiles resulting in energy depletion, developed countries are more stringently strengthening the f...
