Technical Field

The invention relates to the technical field of aluminum alloy doors and windows, in particular to a stain-resistant aluminum alloy door and window and a preparation method thereof.

Background

In recent years, aluminum alloy doors and windows are increasingly favored by people due to the advantages of firm structure, low price, light weight and the like. However, the traditional aluminum alloy doors and windows are not generally subjected to other treatment, some aluminum alloy doors and windows only simply coat and screen a layer of protective coating, and the time is long, so that stains are easily accumulated on the surfaces of the aluminum alloy doors and windows, the surfaces of the aluminum alloy doors and windows are difficult to clean, and only the surface coating can be scraped off to be coated again, so that the time and the labor are wasted.
