Marine reinforced concrete anticorrosion paint and preparation method thereof

Abstract

The invention discloses a kind of reinforced concrete anticorrosive paint in marine engineering and preparation method, comprising prime paint and surface paint, wherein the prime paint is composed of post agent of prime paint and curing agent of prime paint and the surface paint comprises post agent and curing agent of surface paint. The preparation method comprises: preparation technique of prime paint and preparation technique of surface paint, wherein the preparation technique of prime paint is composed of preparation technique of post agent of prime paint and preparation technique of curing agent of prime paint and the preparation technique of surface paint comprises preparation techniques of post agent and curing agent of surface paint. The invention can provide long anticorrosion to steel and concrete structure which is difficult to be kept for a long time in bad environment such as ocean, with excellent oil resistant and anti-chemicals performance, and good cathodic protectioncompatibility performance. The paint can be solidified and dried to form film in water with stronger ornament property.

Description

A kind of anticorrosion coating for marine reinforced concrete and preparation method thereof technical field The invention relates to an anti-corrosion paint, in particular to a marine reinforced concrete anti-corrosion paint and a preparation method thereof, which is suitable for anti-corrosion construction on wet surfaces in tidal range areas. Background technique At present, the status quo of marine concrete anticorrosion is: the seaport wharf in the splash area, because the salt in seawater and rain fog is a highly corrosive substance; CO2 and acid rain in the atmosphere will cause concrete (concrete structure) to lose due to carbonation and neutralization. The protective effect on the steel bars leads to corrosion of the steel bars, which in turn causes the concrete to crack and peel off until the structure is destroyed. Concrete structure damage caused by steel corrosion is quite common and serious. Before 1986, the concrete structure of my country's built ports wa...

"Although this invention can also play a certain anti-corrosion effect, it is not suitable for anti-corrosion construction on wet surfaces in tidal range areas. It cannot be solidified and dried in water to form a film, and the color is single, which cannot meet the needs of different customers and beautify the environment. Anti-corrosion shorter lifespan

Therefore, this invention is not applicable to the anticorrosion of marine concrete
