Abstract

The invention belongs to the field of chemical materials and particularly relates to an aluminum alloy material, a preparation method and application of the aluminum alloy material in a solar energy photovoltaic support. The aluminum alloy material is composed of the following components of, by mass, 0.2%-0.4% of Si, 0.08%-0.20% of Cu, 0.6%-0.8% of Mg, 0.15%-0.25% of Zr, 0.15%-0.25% of Ti, 0.01%-0.15% of Mn and the balance aluminum and inevitable impurities. According to the designed aluminum alloy material, by adding metal elements of Si, Cu, Mg, Zr, Ti, Mn and the like, the grain refinementdegree is improved by a large margin, and the effect in the aspect of promoting the comprehensive properties such as tensile strength, the elongation and the corrosion-resistant property of the aluminum alloy material is significant. The aluminum alloy material is used for preparing a solar energy photovoltaic support profile, so that the corrosion-resistant property of the photovoltaic support prepared from the aluminum alloy material is better than that of a traditional aluminum alloy photovoltaic support component.

Description

technical field [0001] The invention belongs to the field of chemical materials, and in particular relates to an aluminum alloy material, a preparation method and an application in a solar photovoltaic support. Background technique [0002] The lively chemical properties of aluminum alloy make it prone to various forms of corrosion during use, such as pitting corrosion, crevice corrosion, intergranular corrosion, stress corrosion, etc. Anodic oxidation of aluminum can improve the corrosion resistance of aluminum alloy. At present, solar photovoltaic frames and bracket systems are generally made of 6063 aluminum profiles, which have the characteristics of light weight, medium strength, easy processing and forming, and easy anodic oxidation surface treatment. [0003] In recent years, the competition in the solar photovoltaic industry has further intensified. In order to shorten the investment payback period of solar power plants, prolong the service life of solar power plant...
