Description

technical field

[0001] The invention relates to a seawater corrosion inhibitor for copper, namely a low-toxicity and high-efficiency thiazole compound used to inhibit the corrosion of metal copper and its products in seawater or sodium chloride medium, and its preparation and application. Background technique

[0002] With the continuous consumption of various resources on land, the development and utilization of marine resources has become an inevitable way to solve the current resource depletion. However, seawater is a strong electrolyte solution with strong corrosiveness, which greatly limits the development and utilization of marine resources. Therefore, only by solving the corrosion problem of metal materials in seawater can the development and utilization value of marine resources be truly reflected.

[0003] Copper has excellent mechanical strength, machinability, electrical conductivity, thermal conductivity, weldability and other characteristics, and has been widel...
