Abstract

The invention discloses an anti-abrasion aluminum alloy door and window and a preparation method thereof. The preparation method includes the steps that firstly, styrene, carbon black, isopropanol, urea resin, lauryl sodium sulfate and polyvinyl chloride are mixed to prepare a coating composite; secondly, an aluminum alloy door and window base body is subjected to oil removal sequentially with alkaline liquid and a surfactant; thirdly, the surface of the aluminum alloy door and window base body obtained after oil removal is cleaned with ethyl alcohol and water; fourthly, the cleaned surface of the aluminum alloy door and window base body is coated with the coating composition and heated to prepare the anti-abrasion aluminum alloy door and window, wherein the composition is prepared from, by weight, 5 parts of styrene, 4-8 parts of carbon black, 30-40 parts of isopropanol, 40-50 parts of urea resin, 5-9 parts of lauryl sodium sulfate and 10-15 parts of polyvinyl chloride. The anti-abrasion aluminum alloy door and window prepared through the method have excellent mechanical properties and abrasion resistance.

Description

technical field [0001] The invention relates to doors and windows, in particular to wear-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. In addition,...
