Problems solved by technology

Although an oxide film is formed on the surface of the aluminum alloy in the natural environment to resist corrosion, the oxide film formed on the surface of the aluminum alloy in the natural environment is about 4nm thick, loose and porous and has an uneven structure. Occurs from the pores of the oxide film, or from the wear of the oxide film, resulting in metal failure, which cannot meet the development requirements of today's construction field

Abstract

The invention discloses a novel high-strength anti-corrosion building curtain wall frame. The curtain wall frame comprises Mg0.2%, Si 2.0%, Cu4.0%, Mn0.2%, Fe0.2%, Zr0.1% by weight percentage, Er0.1%, Cr0.01%, Ni0.01%, Ti0.1%, Al balance. The curtain wall frame is through (1) smelting; (2) adding Al-5Ti-B, Al-lOSr and RE three kinds of metal refinement modifiers to add refinement modifiers; (3) standing for 2h under the condition of 100MPa to form Ingot casting; (4) five hot rolling and three cold rolling under ultrasonic vibration; (5) modification by C and V lasers and (6) surface treatment with octadecyltrichlorosilane solution to obtain finished products. The present invention uses various means to modify and process the material of the curtain wall frame, so that the curtain wall frame can maintain the integrity of the oxide film even under harsh working conditions, avoid metal failure, and meet the requirements of today's industrial development.

Description

technical field [0001] The invention relates to the construction field, in particular to a novel high-strength anti-corrosion building curtain wall frame. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. In related technologies, aluminum alloy has the advantages of low melting point, corrosion resistance, heat resistance, wear resistance, easy coating and good processability, etc. However, aluminum alloy rarely has the strength and formability of steel, so that aluminum alloy cannot completely replace steel In order to reduce the weight of the curtain wall and reduce the consumption of energy and resources. Moreover, with the development of the application of aluminum alloys, people hope that aluminum alloys can be used in different fields and environments, so the requirements for the...
