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

Abstract

The invention relates to a heavy anti-corrosion coating material. The material does not need solvent and comprises a main agent system and a curing agent system; graphene-modified polycaprolactone is adopted as a toughening agent in the main agent system, and the anti-corrosion coating material can be directly applied in a waterless environment or water environment through a hand coating method, an apply coating method and a brush coating method. By adopting the material and a using method thereof, the zero-solvent content is achieved; meanwhile, the long effectiveness of the anti-corrosion effect and thick coating are achieved, the technical problem of steel structure corrosion prevention in a severe environment of a splash zone is effectively solved, the constructability and protective capability of ocean engineering corrosion prevention are greatly improved, and the technical progress in the coating field in China is promoted; in addition, the engineering construction cost is greatly lowered, the expensive repair and maintenance cost and precious fresh water resources are saved for the state, and the good social and economic benefits are achieved.

Description

technical field [0001] The invention relates to a heavy-duty 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 diffe...
