Abstract

The invention discloses an antioxidant aluminum alloy surface treating agent. The antioxidant aluminum alloy surface treating agent is prepared by mixing the following raw materials, in percentage bymass, of 5% to 10% of fluoride, 2% to 7% of an oxidant, 3% to 8% of inorganic salt, 3% to 7% of a stabilizer, 0.5% to 5% of a coalescing agent, 0.5% to 5% of a corrosion inhibitor and 56% to 88% of water, wherein the coalescing agent is specifically a mixture of fluoboric acid and fluosilicic acid, a ratio of the fluoboric acid to the fluosilicic acid is 1:1, the stabilizer is organic acid, specifically a mixture of oleic acid and malonic acid, a ratio of the oleic acid to the malonic acid is 1.5:1, and the corrosion inhibitor is specifically ammonium citrate and glycolic acid. The invention relates to the technical field of metal surface treatment. The antioxidant aluminum alloy surface treating agent solves the problems that an existing aluminum alloy surface antioxidant treating agent has defects in color and compactness of a formed protective film, a preparation process is tedious, and pollution is high.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an oxidation-resistant aluminum alloy surface treatment agent. Background technique [0002] The surface of aluminum and aluminum alloy products is relatively easy to oxidize during use or storage, and a layer of white substance is formed to adhere to the surface, which not only affects the appearance but also affects the strength. Therefore, high-quality industrial aluminum alloy profile manufacturers will carry out anti-oxidation treatment on the profile surface . [0003] The proper method of anti-oxidation treatment in the prior art is generally an extremely oxidized matte surface, which is to treat the surface of the aluminum alloy with a treatment agent, and react with it to form a protective film, which plays the role of isolating air and water, but the existing The anti-oxidation treatment agent for aluminum alloy surface has insufficient color and compac...
