Abstract

The invention discloses an anti-fading and anti-corrosion aluminum veneer curtain wall. The curtain wall comprises an aluminium alloy panel and an inner core structure. The aluminium alloy panel at least covers the outer surface of the inner core structure and surfaces of all sides. A manufacturing method of the aluminium alloy panel comprises the steps that the surface of an aluminium alloy basematerial is chromized, the chromized surface is etched to form nicks distributed irregularly, and finally the whole surface is sprayed with composite fluorocarbon coating. The anti-fading and anti-corrosion aluminum veneer curtain wall has the advantages that the irregular nicks are carved on the aluminium alloy panel, then the fluorocarbon coating is sprayed, the firmness of a fluorocarbon protection membrane is effectively improved, and the fluorocarbon protection membrane is prevented from falling off in the environment such as acid rain, salt fog and polluted air; by additionally using thespecially-made aluminium alloy base material and the specially-made composite fluorocarbon coating, the anti-fading and anti-corrosion performance of the whole curtain wall can reach to 4-6 times ofa traditional aluminum veneer curtain wall, and the veneer curtain wall further has the advantages of being firm in structure, convenient to install and good in sound absorption and heat preservationeffect.

Description

technical field [0001] The invention relates to the technical field of curtain walls, in particular to an anti-fading and anti-corrosion aluminum veneer curtain wall. Background technique [0002] With the development of social economy, the changes of the city are changing with each passing day. For the appearance of the city and the beauty of the buildings, not only the outer walls of old buildings need outer curtain walls, but also new buildings need outer curtain walls. The use of glass curtain walls is prone to light pollution, and must be inspected and replaced at regular intervals. The use of slate curtain walls is not only inconvenient to install but also not conducive to environmental protection. At present, aluminum veneer curtain wall is widely used due to its advantages of no light pollution, light weight and high compressive strength. [0003] However, the traditional aluminum veneer curtain wall will fade and corrode to varying degrees after several years of us...
