Anticorrosion coating material

Abstract

The invention relates to an antisepsis coating layer material which requires no solvent and comprises a main agent system and a curing agent system; the antisepsis coating layer material can be directly used for coating by means of a manual-coating method, a coating method and a brushing method under the water-free or water environment. The antisepsis coating layer material and the usage method realize zero content of solvent and realize the long effectiveness and thick coating of antisepsis effect at the same time, effectively overcome the difficulty of antisepsis technique of steel structure under severe environment of splash area, greatly improve the construction performance and protection capability of antisepsis of ocean engineering, impulses the progress of technique on the nationalcoating field, greatly reduce the engineering construction cost, save expensive maintenance and curing expense and precious fresh water resource for China and gain excellent social and economic benefits.

Description

technical field [0001] The invention relates to an anti-corrosion technology, in particular to a heavy-duty anti-corrosion coating material for steel structures in ocean splash zones. Background technique [0002] According to statistics, the annual loss caused by corrosion in the world accounts for 2%-4% of the gross national economic product, which is greater than the sum of losses caused by natural disasters such as fire, wind, flood and earthquake. The country attaches great importance to marine corrosion and protection research. my country is a large ocean country, with a coastline of more than 18,000 kilometers and a sea area of ​​more than 3 million kilometers under its jurisdiction 2 , Marine corrosion and protection is one of the key issues that need to be seriously resolved in my country's economic development. In terms of anti-corrosion of marine steel structures, the corrosion environment is different, and the anti-corrosion measures adopted are different. Due...

AI Technical Summary

Problems solved by technology

This kind of protective sleeve has high corrosion resistance, high plasticity and high weldability, and will not cause corrosion resistance and stress corrosion cracking. It has high stability in preventing the growth of microorganisms, but it is expensive and has fatal flaws: Once seawater seeps in, the corrosion becomes more serious

However, although these coating materials achieve environmental protection and long-term performance, the cost is too high when they are applied to the splash zone

At the same time, the material is too demanding for construction, and cannot be used for anti-corrosion repair of steel structures in the ocean splash zone
