Problems solved by technology

[0003] The upper aluminum profile structure is generally composed of inner and outer profiles and heat-insulating strips connecting the inner and outer profiles in the middle. Generally, two heat-insulating strips are set up and down at intervals, and the stability is relatively low, so that the movable window sash structure is unstable and shakes back and forth
In addition, if the mobile window sash is derailed, the mobile window sash is easy to fall from a high altitude, and there is a potential safety hazard
[0004] In addition, when the aluminum alloy parts are exposed to the air, due to the oxygen, moisture, temperature changes and other corrosive factors in the air, the corrosion of the aluminum alloy parts is inevitable. When the long-term corrosion is superimposed, it will directly cause the aluminum alloy parts The performance is greatly reduced, and it cannot continue to work. Therefore, how to improve the corrosion resistance of aluminum alloy parts is a technical problem that needs to be solved

Embodiment 1

[0042] The casting process of the aluminum alloy profile of present embodiment 1 is specifically:

[0043] Step 1.1), smelting and casting: Put the ingot and an appropriate amount of AlTiB grain refiner into the melting furnace for melting, and then put in the nano-carbonate after the melting is complete, and at the same time pass inert gas from the bottom of the melting furnace, and heat up to 800°C ~850℃ until it is completely melted, keep it warm for 45min, and then filter it through a foam ceramic filter plate to obtain an alloy melt, and pour it, open the mold after the alloy melt solidifies, and cool the ingot to room temperature, and if necessary Ingot saw cut to length. The ingots include recycled aluminum profiles, and the addition of alloy elements is detected and controlled so that the mass percentage content of each element is: 0.25% silicon, 2.7% magnesium, 0.12% iron, 3.2% copper, 0.08% manganese, 1.2% Zinc, 0.05% titanium, 0.02% zirconium, 0.15% other elements,...

Embodiment 2

[0051] The casting process of the aluminum alloy profile of present embodiment 1 is specifically:

[0052] Step 1.1), smelting and casting: Put the ingot and an appropriate amount of AlTiB grain refiner into the melting furnace for melting, and then put in the nano-carbonate after the melting is complete, and at the same time pass inert gas from the bottom of the melting furnace, and heat up to 800°C ~850°C until it is completely melted, keep it warm for 30 minutes, and then filter it through a foam ceramic filter plate to obtain an alloy melt, and pour it. Ingot saw cut to length. The ingots include recycled aluminum profiles, and through detection and control of the addition of alloy elements, the mass percentage content of each element in it is: 0.3% silicon, 3% magnesium, 0.15% iron, 3.2% copper, 0.1% manganese, 1.4% Zinc, 0.02% titanium, 0.04% zirconium, 0.1% other elements, and the rest is aluminum.

Abstract

The invention relates to the technical field of door and window aluminum profiles, and particularly discloses an aluminum alloy profile and a manufacturing method thereof. The method comprises castingand powder spraying of the aluminum alloy profile, wherein the powder spraying process specifically comprises the steps of: taking bentonite, adding water, stirring till the bentonite is completely expanded and completely dispersed in the water to form suspension liquid; adding recycled aluminum particles, continuously and completely stirring, adding a silver antibacterial agent and boron nitride, carrying out wet ball milling, and carrying out spray drying to obtain modified aluminum powder; taking nitrogen and oxygen as working gases, and spraying and depositing the working gases on the surface of the aluminum alloy profile under the carrying action of an ionic gas. According to the manufacturing method, the bonding strength of a coating and the surface of the aluminum alloy profile canbe enhanced, the oxidation resistance, aging resistance, toughness and corrosion resistance of a surface layer are remarkably improved, and meanwhile the aluminum profile is endowed with an excellentantibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of door and window aluminum materials, and in particular relates to an aluminum alloy profile and a manufacturing method thereof. Background technique [0002] Aluminum profile sliding doors and windows are widely used in the current building windows. They have the advantages of saving space and increasing the indoor lighting effect. The moving window sash between them, and the upper part is the aluminum profile for the moving window sash to cooperate with the solid upper slide. One end of the upper part is installed with a fixed glass, and the other end is matched with the solid upper slide. [0003] The upper aluminum profile structure is generally composed of inner and outer profiles and heat-insulating strips connecting the inner and outer profiles in the middle. Generally, two heat-insulating strips are arranged at intervals up and down, and the stability is relatively low, so that the movable window sa...
