Embodiment 1

[0031] Send 0.5% magnesium, 0.3% silicon, 0.6% manganese, 0.01% copper, 0.01% chromium, and 98.58% aluminum into the electric melting furnace, and adjust the temperature in the electric melting furnace to 750°C. After keeping warm for 2 hours, the raw material in the electric melting furnace becomes a melt, and then the melt is kept warm and sent to an emulsifier at 700°C for emulsification. After about 1 hour, the mixture is cast and rolled into a green body, and the green body is heated at a temperature of 450 The annealing treatment is carried out at 450°C, and finally extruded by an extruder at 450°C to form a profile, and after cooling down to normal temperature, a formed aluminum alloy profile is obtained. Degrease the profile with an alkaline degreasing agent, and then wash it with water; after washing, carry out anodic oxidation, the bath temperature during oxidation is 15°C, and the current density is 130A / m 2 , and then cleaned; then electrolytic coloring, hot water ...

Embodiment 2

[0033] Feed 0.55% magnesium, 0.35% silicon, 0.7% manganese, 0.02% copper, 0.03% chromium, and 98.35% aluminum into the electric melting furnace, and adjust the temperature in the electric melting furnace to 780°C. After 2.5 hours of heat preservation, the raw material in the electric melting furnace becomes a melt, and then the melt is kept warm and sent to an emulsifier at 700°C for emulsification. After about 1.5 hours, the mixture is cast and rolled into a green body, and the green body is heated at temperature It is annealed at 470°C, and finally extruded by an extruder at 480°C to form a profile, and after cooling down to normal temperature, a formed aluminum alloy profile is obtained. Degrease the profile with an alkaline degreasing agent, and then wash it with water; after washing, carry out anodic oxidation, the bath temperature during oxidation is 20°C, and the current density is 150A / m 2 , and then cleaning; then electrolytic coloring, hot water cleaning, the tempera...

Embodiment 3

[0035] Send 0.6% magnesium, 0.4% silicon, 0.8% manganese, 0.05% copper, 0.05% chromium, and 98.1% aluminum into the electric melting furnace, and adjust the temperature in the electric melting furnace to 800°C. After 3 hours of heat preservation, the raw material in the electric melting furnace becomes a melt, and then the melt is kept warm and sent to an emulsifier at 700°C for emulsification. After about 2 hours, the mixture is cast and rolled into a green body, and the green body is heated at a temperature of 500 The annealing treatment is carried out at 500°C, and finally extruded by an extruder at 500°C to form a profile, and after cooling down to normal temperature, a formed aluminum alloy profile is obtained. Degrease the profile with an alkaline degreasing agent, and then wash it with water; after washing, carry out anodic oxidation, the bath temperature during oxidation is 5--25°C, and the current density is 160A / m 2 , and then cleaning; then electrolytic coloring, ho...

Abstract

The invention relates to aluminum alloy material processing and concretely relates to a method for preparing an aluminum alloy material through electrophoresis. The method comprises the steps of delivering raw material components into an electric melting furnace according to a certain ratio, and heating to form a molten mass; mixing and emulsifying the molten mass to form a uniform mixture; carrying out cast rolling on the mixture to form a blank; carrying out annealing treatment on the blank; extruding the annealed blank to form an aluminum alloy profile; degreasing the profile, and then, washing; anodizing after washing, and then, washing; electrolytically coloring and washing with hot water; electrophoretically coating the washed profile, washing with water, and leaching; curing and packaging. According to the invention, all the components are mixed by using an emulsifying machine, so that the components are relatively uniformly mixed, the quality of the formed material is high, and the emulsifying efficiency is high; the profile is electrophoretically coated to form a layer of paint film on the surface, so that the profile can be prevented from being soaked by water, mud, mortar and acid rain, and the coating effect of the profile is improved.

Description

technical field [0001] The invention relates to a production method of an aluminum alloy material, in particular to a method for preparing an aluminum alloy material by an electrophoresis method. Background technique [0002] Due to the high strength of aluminum alloy profiles, it is not easy to rust, and compared with ordinary steel, it is lighter in weight, which is more conducive to the construction of construction projects, and has been widely used. Aluminum alloy doors and windows are the main body of building energy consumption. As a part of the building, they should have the same service life as the building. However, due to the defects in the process and the influence of the harsh environment, the existing aluminum alloy Corrosion performance is difficult to reach the service life of the building. At present, in order to improve the coating effect, corrosion resistance and surface finish of the workpiece, the workpiece can be coated. Electrophoretic painting is to d...
