Abstract

The application discloses an automobile interior assembly, which includes a plastic interior panel and a ceramic panel. The ceramic panel is clamped under the plastic interior panel. The front of the plastic interior panel is sunken inward to form an air outlet. The plastic interior panel The back of the panel is provided with a plurality of cushioning foams, and the plurality of cushioning foams are respectively bonded to the back of the plastic interior panel, wherein the ceramic panel includes a metal sheet, and one side of the metal sheet is provided with a passivation film layer and a primer layer in sequence. Layer, ceramic color paint layer and ceramic topcoat layer. The other side of the metal sheet is provided with a hot melt adhesive layer. The passivation film layer can enhance the anti-corrosion performance of the metal sheet during processing, and the primer layer can avoid The risk of scratches on the surface of the metal sheet, the ceramic color paint layer can improve its color, the ceramic topcoat layer can finish the surface of the metal sheet when spraying, and can improve the weather resistance of the ceramic topcoat layer, and the hot melt adhesive layer Enables fast bonding of metal sheets to plastic substrates.

Description

technical field [0001] The present application relates to the technical field of automotive interior parts, in particular to an automotive interior assembly. Background technique [0002] At present, energy saving and environmental protection are the general trend of the development of transportation vehicles, and they are also important issues related to the sustainable development of human beings. Body weight reduction is one of the most effective measures for reducing fuel consumption and emissions. The lightweight of the car is to reduce the overall weight of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption, and reduce exhaust pollution; in order to meet the requirements of lightweight car body, Most of the body and interior parts are made of aluminum alloy. Aluminum alloy materials have the advantages of low density, high strength, and high rigidity,...
