Problems solved by technology

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.

Abstract

The invention discloses resin-based metal copper anticorrosion coating and a preparation method thereof. The coating comprises, by weight, 0.2-0.4 part of p-tert-amyl phenol, 1-2 parts of sodium lauroyl sarcosine, 1-2 parts of amino trimethylene phosphonic acid, 10-14 parts of vinyl trimethoxy silane, 200-300 parts of 1.8-2g/l citric acid solution, 13-17 parts of silane coupling agent KBM5103, 100-110 parts of tetraethylortho silicate, 30-37 parts of hexafluorobutyl acrylate, 0.1-014 part of azodiisobutyronitrile, 5-7 parts of 20-25% ammonium water, 4-5 parts of ferroferric oxide, 2-3 parts of perfluorosulfonate resin, 1-2 parts of borax, 0.2-0.5 part of beta-hydroxyl alkyl amide and 3-4 parts of sorbitol monoleate. The resin-based metal copper anticorrosion coating can form various hybridization coating surfaces of different structures, and the different-structured coating surfaces combine with exposed low-surface-energy ethylene groups to allow the coating to have a super-hydrophobic property.

Description

technical field [0001] The invention relates to the technical field of metal anticorrosion, in particular to a resin-based 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 ye...
