Scratch-resistant aluminum alloy door and window and preparation method thereof

Abstract

The invention discloses a scratch-resistant aluminum alloy door and window and a preparation method thereof. The scratch-resistant aluminum alloy door and window comprises an aluminum alloy door and window body, the surface of the aluminum alloy door and window body is sequentially provided with a first scratch-resistant coating and a second scratch-resistant coating, the thickness of the first scratch-resistant coating is 1.2-1.8 mm, the thickness of the second scratch-resistant coating is 2.0-2.2 mm, the surface of the aluminum alloy door and window needs ash removal, oil removal, polishing,cleaning and air drying treatment, and the first scratch-resistant coating and the second scratch-resistant coating are cured in a nitrogen atmosphere; the surface of the aluminum alloy door and window prepared by the method has high abrasion resistance and scratch resistance, and can effectively prevent the problems of affecting the aesthetic appearance and service life of the aluminum alloy door and window surface after being scratched; and by controlling the first scratch-resistant coating and the second scratch-resistant coating to be cured in the nitrogen atmosphere, the retention rate of the surface gloss of the formed first scratch-resistant coating and the second scratch-resistant coating can be greatly improved, and the scratch-resistant performance of the surface is synchronously improved.

Description

technical field [0001] The invention relates to the field of aluminum alloy doors and windows, in particular to a scratch-resistant aluminum alloy door and window and a preparation method thereof. Background technique [0002] Doors and windows are an important part of the building envelope structure system. According to their constituent materials, common doors and windows include wooden doors and windows, glass doors and windows, and aluminum alloy doors and windows. Wooden doors and windows are flammable, easy to deform, difficult to repair after being damaged, easy to crack, scar, poor corrosion resistance, susceptible to insects, etc., and prone to mildew when exposed to moisture; glass doors and windows have fragile defects that limit their application ; Aluminum alloy doors and windows are widely used in industrial production because of their advantages such as not easy to rust, easy to process, relatively low price, light weight, and can be made into complex sections...
