Abstract

The invention discloses a self-cleaning corrosion-resistant aluminum profile and relates to the technical field of aluminum profiles. The self-cleaning corrosion-resistant aluminum profile comprises an aluminum profile matrix and an epoxy resin coating coating the surface of the aluminum profile matrix, wherein the epoxy resin coating is prepared by mixing a component A and a component B accordingto a weight ratio of 3-5 to 1; the component A comprises the following raw materials in parts by weight: 40-50 parts of a bisphenol A epoxy resin emulsion, 5-10 parts of modified titania nanoparticles, 0.5-2 parts of fumed silica, 5-10 parts of diatomite, 2-5 parts of graphene oxide, 3-7 parts of texanol, 2-5 parts of polyethyleneglycol diglycidyl ether, 0.5-2 parts of a dispersing agent, 0.5-2 parts of a flatting agent, 12-15 parts of water, 2-5 parts of a coupling agent and 0.2-1 part of nonylphenol polyoxyethylene ether; the component B is a waterborne epoxy amine curing agent. The coatingprepared by the invention is excellent in pollution resistance, bactericidal activity, corrosion resistance and wear resistance and is excellent in bonding strength with an aluminum alloy base material, a long-term protection effect is achieved, the service life of the aluminum alloy is prolonged, and the application range is widened.

Description

technical field

[0001] The invention relates to the technical field of aluminum profiles, in particular to a self-cleaning and corrosion-resistant aluminum profile. Background technique

[0002] Aluminum and aluminum alloys are one of the most widely used materials in non-ferrous metals. Aluminum alloys have many excellent properties such as low density, easy processing, low thermal expansion coefficient, high thermal conductivity, high specific stiffness and specific strength. It has been widely used in daily production and life, as well as aviation, automobiles, high-speed rail, engine pistons, optical instruments, missile mosaic structures and other fields. However, with the further development of industrial production, higher requirements are put forward for the surface properties of aluminum alloys. People usually use the method of coating the aluminum alloy surface to improve its surface properties.
