Abstract

The invention discloses an aluminum-alloy electrophoretic wood-grain profile and a process for preparing the aluminum-alloy electrophoretic wood-grain profile. The process comprises the following steps of: preparing the refining alterative: smelting a mixed-rare-earth ingot, an AlTiB alloy and a pure aluminum ingot in a crucible to prepare the refining alterative; smelting an aluminum alloy: adding an alloying element, the refining alterative and aluminum into an energy-saving casting furnace, heating and smelting; preparing the profile: casting a solution into a cast ingot, and forming the aluminum-alloy profile by extruding; anodizing the aluminum-alloy profile; and carrying out electrophoretic coating on the aluminum-alloy profile. The aluminum-alloy electrophoretic wood-grain profile prepared by adopting the process has uniform surface coating, strong adhesion, good coverage and can be transferred completely and clearly, and is free from the appearance defect of exposure of the base outside the powdery coating, has 110-115 gloss units and is far superior to the traditional aluminum-alloy wood-grain profile in gloss.

Description

technical field [0001] The invention relates to an aluminum alloy electrophoretic wood grain profile and a preparation process thereof. Background technique [0002] Aluminum alloy is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, and lithium. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in various industries in industry. Aluminum alloy extruded profiles are also widely used in the construction industry for aluminum doors and windows, counters, stair handrails, inner walls of train cars, elevator rooms and other parts that need to be decorated due to their low density, high strength, good pla...
