Anticorrosive aluminum product and preparation method thereof

Abstract

The invention relates to the technical field of aluminum-based composite material, and provides an anticorrosive aluminum product and a preparation method thereof. A substrate layer is mainly prepared from the following components in parts by weight: 50 to 60 parts of aluminum powder, 20 to 30 parts of copper powder, 5 to 6 parts of nanometer zirconium dioxide, 3 to 4 parts of samarium element, 3 to 4 parts of ytterbium element and 1 to 2 parts of corrosion inhibitor. A coating layer is mainly prepared from the following components in parts by weight: 30 to 40 parts of epoxy resin, 5 to 7 parts of mesoporous SBA-15, 0.5 to 1.0 part of beta-(2,6-ditert-butyl-3-hydroxyphenyl)propionic octadecyl ester, 0.5 to 1.0 part of 2,5-ditert-butyl-3-methylphenol, 0.2 to 0.5 part of N-(fluclorolone methyl thiocarbonate)phthalimide, 0.2 to 0.5 part of benzimidazolyl methyl carbamate, 10 to 13 parts of stainless powder, and the like. The preparation method comprises the following steps of preparation of the substrate layer and the coating layer, spraying of paint and the like. The anticorrosive aluminum product has the advantages that the environment-friendly effect is realized, the comprehensive property is excellent, and the anticorrosive durability of the aluminum product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aluminum-based composite materials, in particular to an anti-corrosion and durable aluminum product and a preparation method thereof. Background technique [0002] Aluminum metal is tough and light, ductile, and easy to conduct electricity. It can be used as a structural material for aircraft, vehicles, ships, ships, and rockets. However, pure aluminum is too soft, and its application range is limited, so people always add it to it. A small amount of copper, magnesium, manganese, etc., is made into aluminum alloy to improve the physical and chemical properties of aluminum. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. However, aluminum alloys still have problems such as poor toughness, low hardness, no wear resistance, no impact resistance, ...

AI Technical Summary

Problems solved by technology

Existing aluminum products generally use multiple metal or alloy coating structures, but there are also disadvantages such as poor anti-corrosion performance, easy wear, and poor acid resistance, and it cannot effectively prevent electrochemical corrosion and other phenomena, and it also consumes a lot of precious metal resources. The production cost is high, and the use of a single anti-corrosion coating is far from ideal in terms of durability, gloss, hardness and anti-corrosion performance.
