Heat-resistant metallic copper anticorrosion coating and method for preparing same

Abstract

The invention discloses a heat-resistant metallic copper anticorrosion coating and a method for preparing the same. The heat-resistant metallic copper anticorrosion coating comprises, by weight, 2-3 parts of bisphenol A phosphite, 2-3 parts of sorbitol, 10-14 parts of vinyl trimethoxy silane, 200-300 parts of 1.8-2 g / l citric acid solution, 13-17 parts of silane coupling agents KBM5103, 100-110 parts of tetraethoxysilane, 30-37 parts of hexafluorobutyl acrylate, 0.1-0.14 part of azodiisobutyronitrile, 5-7 parts of 20-25% ammonia water, 4-5 parts of ferriferous oxide, 0.2-0.4 part of dimethyl vinyl phosphate ester, 1-2 parts of aluminum ammonium sulfate, 0.5-1 part of calcium acetylacetonate, 4-5 parts of N-methyl pyrrolidone and 0.1-0.2 part of nonylphenol. The heat-resistant metallic copper anticorrosion coating has the advantages that hybrid coating surfaces with different morphological structures can be formed by the heat-resistant metallic copper anticorrosion coating; the coating surfaces which are of different structures can be combined with exposed ethylene groups with low surface energy, and accordingly the heat-resistant metallic copper anticorrosion coating has a super-hydrophobic characteristic.

Description

technical field [0001] The invention relates to the technical field of metal anticorrosion, in particular to a heat-resistant metal copper anticorrosion coating and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, traditional metal coating protection or surface treatment methods are facing severe challenges. For example, although electroplating can form a uniform and dense protective layer, the electroplating process will generate a lot of waste water, waste gas and waste residue , which contains highly toxic substances such as heavy metal chromium and cyanate, which poses a serious threat to the environment; and the metal surface phosphating treatment technology, the sediment and phosphate produced by the phosphating process are likely to cause rich oxidation of water quality, nitrite, Water pollution by heavy metal ions also requires new surface treatment methods. In recent...

However, even the smooth solid surface with the lowest surface energy has a contact angle with water of only 119°, therefore, superhydrophobic surfaces cannot be obtained only by reducing the surface energy.
