High-peel-strength nano aluminium plastic composite panel

Abstract

The invention relates to a high-peel-strength nano aluminium plastic composite panel which is mainly used for decorating the external wall of a construction. The nano aluminium plastic composite panel is characterized by orderly comprising a nano baking finish surface layer, a fluorocarbon coating (2), a primer coating (3), a front aluminium plate (4), a plastic layer (6), a back aluminium plate (8) and an anti-corrosive bottom layer (9) from top to bottom. In the invention, the compact nano baking finish surface layer is baked on the surface of the fluorocarbon coating, thus, when oil stain or dust contacts the surface of the aluminium plastic composite panel, the dirt can not permeate into molecules due to the compact nano surface and can fall off along with rain when rain flushes. Therefore, the aluminium plastic composite panel has the advantages of favorable anti-dirt effect, strong self-cleaning performance and excellent acid and alkali resistance. By means of the invention, the construction cleaning and maintenance cost in the later period is greatly lowered. Since a binding film is arranged between the aluminium plate layer and the plastic layer, the process is simple, and the aluminium plastic composite panel has the advantages of high peel strength and long service life, and satisfies the requirement of modern decoration for high grade.

Description

(1) Technical field [0001] The invention relates to a nano-aluminum-plastic composite board with high peeling resistance. It is mainly used for building exterior wall decoration. It belongs to the technical field of decorative materials. (2) Background technology [0002] Aluminum-plastic composite panels are widely used as indoor and outdoor wall decorations because of their easy processing and light weight. The aluminum-plastic composite panels used for building exterior walls have to pass the test of wind, sun and rain for a long time because of their use environment. The paint surface of traditional aluminum-plastic composite panels has a gully-like molecular structure, so when stains adhere to the surface, tiny molecules will penetrate into its molecular gaps, and the stain resistance is poor. And because of the poor acid and alkali resistance of the paint surface, to remove the stains adsorbed on its surface, only neutral chemical detergent can be used to clean it. ...

AI Technical Summary

Problems solved by technology

The traditional aluminum-plastic composite panel has a gully-shaped molecular structure on the paint surface, so when the stain adheres to the surface, the tiny molecules will penetrate into its molecular gap, and the stain resistance is poor.

And because of the poor acid and alkali resistance of the paint surface, to remove the stains adsorbed on its surface, only neutral chemical detergent can be used to clean it.

It will greatly increase the cleaning and maintenance costs of the later buildings

And the ordinary aluminum-plastic composite board, the aluminum layer and the plastic layer are bonded with glue, the composite process is complex, the peeling strength is poor, and the service life is short, it is difficult to meet the high-quality requirements of modern decoration
