Abstract

The invention relates to an electric iron and steel structure anticorrosive paint suitable for maritime climates, and a preparation method thereof. According to the preparation method, a first component and a second component are separately prepared; the first component preparation method comprises: adding a bisphenol A type epoxy resin, a bisphenol F type epoxy resin, a hydroxyl-saturated polyester resin and a fluorocarbon resin to the mixed liquid of xylene, n-butyl acetate and methyl isobutyl ketone, carrying out dispersed dissolving, adding rutile type titanium dioxide, refined pickled quartz sand, polyacrylate, polymethylsiloxane, benzotriazole, zinc iso-octoate and fumed silica, and grinding; the second component preparation method comprises: uniformly mixing aliphatic isocyanate, anhydrous xylene and n-butyl acetate; and during the use, the first component and the second component are mixed according to a mass ratio of 1:4. According to the present invention, the anticorrosive paint is based on the characteristics of high humidity, high salinity, high sulfur dioxide content, high acid substance content and the like of the maritime climate, has characteristics of strong adhesion, wear resistance, weather resistance, light aging resistance and salt spray resistance, and can protect the power enterprise iron and steel equipment operated on the seashore.

Description

technical field [0001] The invention belongs to the field of anticorrosion of electric power operation equipment, and in particular relates to an anticorrosion paint suitable for marine climate electric power steel structures and a preparation method thereof. Background technique [0002] With the development of the coastal economy, power companies have built a large number of power facilities on the seashore, mainly steel structures. The marine climate is characterized by high humidity, high salinity, and high sulfur dioxide and acidic substances. Therefore, for the steel structures of electric power enterprises, the relative humidity of the air is higher than its critical value. The marine climate is easy to form a corrosive water film on the surface of the seaside steel equipment of the power company. The ocean atmosphere is rich in a large number of sea salt particles and impurities dissolved in the water film on the steel surface, making this water film become very cor...
