Environment-friendly type ocean anticorrosive paint applicable to large ships

Abstract

The invention discloses environment-friendly type ocean anticorrosive paint applicable to large ships. The environment-friendly type ocean anticorrosive paint is prepared from the following componentsin percentage by weight: 15 to 25 percent of epoxy resin, 5 to 8 percent of ultrafine barium sulfate, 8 to 12 percent of light calcium carbonate, 1 to 3 percent of a thixotropic agent, 5 to 10 percent of a curing agent, 0.1 to 0.2 percent of a film-forming catalyst, 1 to 3 percent of an alga removing agent, 1 to 2 percent of a dispersant, 25 to 35 percent of amine type resin, 0.05 to 0.1 percentof nano silicon dioxide, 5 to 8 percent of toner and the balance of silicon micro-powder. According to the paint disclosed by the invention, a small amount of the film-forming catalyst lanthanum oxideis added; under the catalysis effect, the strength and impermeability performance of a formed film are remarkably improved; the surface strength and anti-chloride ion permeability performance of thepaint are enhanced; the nano silicon dioxide is highly bound to the surface of the film, so that a nano-grade gap of the film is easy to fill and the strength of the film is enhanced.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to an environment-friendly marine anti-corrosion coating suitable for large ships. Background technique [0002] Marine anti-corrosion coatings are substances applied on marine infrastructure to ensure a long anti-corrosion period. They can quickly react with iron atoms on the surface of steel structures to form dual protection effects of physical and chemical, and can resist chloride ion corrosion for a long time. [0003] The data shows that the ocean plays a huge role in the economic and social development of my country's eastern coastal areas. The land area of ​​the 12 coastal provinces, districts and municipalities accounts for only 14% of the country's land area, but its GDP accounts for 60% of the country's total. The national marine economic output value was 8 billion yuan in 1980, 43.8 billion yuan in 1990, 413.3 billion yuan in 2000, 1.3 trillion yuan in 2...
