Combined aluminum honeycomb plate used for automobile interior

Abstract

The invention provides a combined aluminum honeycomb plate used for an automobile interior. The combined aluminum honeycomb plate comprises an aluminum plate and a damp-proof layer between an exterior plate and an aluminum honeycomb panel; the aluminum plate is folded and compressed into the aluminum honeycomb panel of a honeycomb structure, the exterior plate and an interior plate are correspondingly arranged on the upper surface and the lower surface of the aluminum honeycomb panel respectively, the exterior plate is composed of glass fibers and PU materials, the interior plate is composed of glass fibers and PU materials, and the PU materials are sprayed on the glass fibers to achieve foaming forming; the damp-proof layer comprises an epoxy resin plate and a heating component which is solidified inside the epoxy resin plate. The combined aluminum honeycomb plate overcomes the defects in the prior art, is reasonably designed, and is a stable decoration plate inside an automobile, wherein the aluminum honeycomb plate is low in self weight and makes environmental protection easy on the basis of guaranteeing mechanical strength.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration materials, in particular to a composite aluminum honeycomb panel for automobile interior decoration. Background technique [0002] Paper honeycomb products are widely used in the packaging industry, and its unique hollow structure endows the products with special properties - light weight and high strength. When the paper honeycomb surface is compounded with other materials, such as thermoplastic resin, the strength of the paper honeycomb composite board will be greatly improved. The characteristics of high strength, light weight and easy forming of paper honeycomb composite materials make it widely used in my country's rail transit interiors, such as spare tire covers, coat racks, sunroof sliders and other parts; [0003] The existing production techniques of automotive interior trim panels generally include the following types: 1. Injection molding; 2. Compression molding...

AI Technical Summary

Problems solved by technology

These kinds of materials and the processes and technologies used have their own technical defects: injection molding; plastic particles are extracted from petroleum, which belongs to heavy chemical industry and heavy pollution industry. The raw materials themselves have high energy consumption and cost, and are a kind of Non-renewable resources; plastic waste after repeated reuse is difficult to degrade in the natural environment, and excessive use of injection molding by humans will inevitably cause damage to the environment (commonly known as white pollution); PP materials, cotton boards, wood powder boards and hemp fiber boards are molded Forming; these three materials are natural non-renewable materials, limited by natural conditions, cotton, hemp, and wood have a long growth cycle

Usually, after water is spilled on the interior panel of the vehicle, there is only a simple wipe and wait for natural drying, which is easy to mold and dirty. Parking the vehicle in a humid environment for a long time will also cause the interior panel to become moldy

[0004] In addition, for the interior decoration of automobiles, it is necessary to consider that the force and load bearing cannot achieve good results. Therefore, it is necessary to use lightweight aluminum materials and paper honeycomb to make a new type of composite material.
