Description

Technical field

[0001] The invention provides a seawater corrosion-resistant paint, which belongs to the technical field of paint. Background technique

[0002] The ocean can provide mankind with material resources, space resources and energy for survival and development. my country is a large maritime country with a coastline of more than 18,000 kilometers, more than 6,500 coastal islands, and a maritime area under its jurisdiction of more than 3 million square kilometers. my country has abundant marine resources and a thriving marine industry, but the marine environment is very harsh and highly corrosive. Therefore, marine corrosion and protection are issues that urgently need to be resolved in my country’s economic development.

[0003] Most ships use metal shells. In the marine environment, metal is affected by seawater temperature, seawater content, ocean atmospheric temperature, and ocean atmospheric humidity. The degree of corrosion is very serious. Corrosion not only reduc...
