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 a salt spray resistant metal copper anticorrosion coating, made from the following materials according to parts by weight: 1-2 parts of 2-mercaptobenzimidazole, 0.3-1 part of monoalkyl ether phosphate, 2-4 parts of pentaerythritol, 10-14 parts of vinyltrimethoxysilane, 200-300 parts of 1.8-2 g / l citric acid solution, 13-17 parts of silane coupling agent KBM5103, 100-110 parts of tetraethoxysilane, 30-37 parts of hexafluorobutyl acrylate, 0.1-0.14 part of azodiisobutyronitrile, 7-8 parts of 20-25% ammonia, 4-5 parts of iron (II,III) oxide, 1-3 parts of calcium sulphoaluminate, 0.3-1 part of dodecyl glucoside, 0.1-0.2 part of 4,4'-dioctylphenylamine, 1-2 parts of sodium citrate, and 1.7-2 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The salt spray resistant metal copper anticorrosion coating can form hybrid coating surfaces different in form, and the coating surfaces of different structures are combined with exposed low-surface-energy ethylene groups to jointly impart superhydrophobicity to the coating.

Description

Technical field [0001] The invention relates to the technical field of metal anticorrosion, in particular to a salt spray resistant metal copper anticorrosion coating and a preparation method thereof. Background technique [0002] In recent years, as people’s awareness of environmental protection has increased, traditional metal coating protection or surface treatment methods are facing severe challenges. For example, electroplating can form a uniform and dense protective layer, but the electroplating process will produce a lot of waste water, waste gas and waste residues. , Which contains heavy metals such as chromium, cyanate and other highly toxic substances, which poses a serious threat to the environment; and the phosphate treatment technology of the metal surface, the sediment and phosphate produced by the phosphating process can easily cause the rich oxidation of water quality, nitrite, The pollution of heavy metal ions to water quality also requires new surface treatment ...
