Description

1. Technical field

[0001] This product belongs to the field of building materials and involves special nano-coatings and preparation methods thereof. Special nano-coating is used on the surface of aluminum alloy profiles. The doors and windows produced by it have the function of heat insulation and can replace the heat-insulating aluminum alloy doors and windows. 2. Background technology

[0002] Our country is a big energy consumer. Building energy consumption accounts for 28-30% of the country's total energy consumption, while door and window energy consumption accounts for 50% of building energy consumption. Therefore, saving energy is the top priority for the development of the doors and windows industry. my country's construction doors and windows market is composed of aluminum alloy doors and windows, plastic doors and windows, steel doors and windows, wooden doors and windows and other types of doors and windows. Because aluminum alloy doors and windows have good pe...
