Abstract

The invention discloses a scratch-resistant aluminum alloy door window and a preparation method thereof. The preparation method includes: (1), mixing, by weight, 5 parts of glycerol, 4-8 parts of carbon black, 30-40 parts of epoxy propane, 40-50 parts of urea formaldehyde resin, 5-9 parts of polyacrylamide and 10-15 parts of polyvinyl chloride to obtain a coating composition; (2), sequentially using alkaline liquid and a surfactant to deoil an aluminum alloy door window matrix; (3), using alcohol and water to clean the surface of the deoiled aluminum alloy door window matrix; (4), coating the surface of the aluminum alloy door window matrix with the surface cleaned with the coating composition, and heating to obtain the scratch-resistant aluminum alloy door window. The scratch-resistant aluminum alloy door window prepared by the method has excellent mechanical performance, wear resistance and scratch resistance.

Description

technical field [0001] The invention relates to doors and windows, in particular to scratch-resistant aluminum alloy doors and windows 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 which limit their applications. 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 and structures.
