A kind of weathering steel surface stabilization treatment liquid for marine atmospheric environment

Abstract

A weather-resistant steel surface stabilization treatment solution for marine and atmospheric environments. The components are as follows by mass percentage: sealing film resin: 1%~40%, granular resin: 0.1%~10%, and promoting elements: 0.05%~10% , pigment: 5%~20%, defoamer: 0.1%~0.5%, dispersant: 0.1%~0.5%, dustproof agent: 0.1%~0.5%, and the rest is water or organic solvent, which can prevent Cl — While in contact with the substrate, let the water and air required for the formation of the rust layer on the surface of the weathering steel pass through, and contain substances that promote the stabilization of the rust layer on the surface, creating a suitable environment for the generation of the rust layer on the surface of the weathering steel in the marine atmospheric environment. Realize the maintenance-free use of weathering steel in marine atmospheric environment.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion of steel materials, in particular to a surface stabilization treatment liquid for weather-resistant steel used in marine and atmospheric environments. Background technique [0002] During the use of weathering steel, the surface rust structure gradually tends to be dense and stable, which can isolate the contact between atmospheric corrosion factors and the weathering steel matrix, avoid continuous corrosion of the weathering steel matrix, and achieve atmospheric corrosion resistance. The best way to use weathering steel is to use it naked. However, in the natural environment, it takes 3 to 10 years to stabilize the rust layer on the surface of weathering steel. In the marine atmosphere environment, due to Cl — The existence of the steel changed the evolution path of the surface rust structure, resulting in the inability to form a dense and stable rust layer, so that the weathering steel co...

Problems solved by technology

However, the disadvantage of this method is similar to that of Patent No. 3, and it cannot prevent Cl — Contact with the substrate

[0007] The currently developed methods for stabilizing the rust layer on the surface of weathering steel cannot effectively prevent Cl in the marine and atmospheric environment. — The contact with the weathering steel substrate creates a suitable environment for the stable formation of the rust layer on the weathering steel surface
