Abstract

The invention discloses an anti-aging sunflower aluminium alloy profile. The anti-aging sunflower aluminium alloy profile comprises an aluminium alloy profile substrate and anti-aging matte fluorocarbon finish paint which coats the surface of the aluminium alloy profile substrate; the anti-aging matte fluorocarbon finish paint is prepared from the following raw materials in parts by weight: 30 to40 parts of water-based fluorocarbon resin, 15 to 25 parts of modified epoxy resin, 1.3 to 1.5 parts of polytetramethylene ether glycol, 0.5 to 1 part of a levelling agent, 0.6 to 0.9 part of a defoaming agent, 0.5 to 0.8 part of a matting agent, and 0.3 to 0.6 part of a coalescing agent. The anti-aging sunflower aluminium alloy profile has excellent anti-aging property, and meanwhile, has good film-forming property and machinability.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy plates, in particular to an aging-resistant sunflower aluminum alloy profile. Background technique [0002] Aluminum alloy is a kind of industrial building material, which is used in various industries according to different materials. According to the surface treatment method, it can be divided into two categories: non-painted products and painted products. The industries used include aircraft structures, rivets, missile components, truck wheels, packaging and thermal insulation aluminum foil, heat exchangers, bulkheads, wing ribs, spars, etc. [0003] However, existing aluminum alloys, such as sunflower aluminum alloy profiles, have low aging resistance and cannot meet people's daily needs. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes an aging-resistant sunflower aluminum alloy profile; the present inven...
