Problems solved by technology

[0009] However, there are still some problems in glass flake coatings. For example, glass flakes are inorganic materials with high brittleness, poor compatibility with organic polymers, low thermal conductivity of glass, which is not conducive to improving the heat resistance of the coating, and poor weather resistance. Wait
Particularly poor corrosion resistance against fluorine

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a corrosion-resistant glass flake resin. Background technique [0002] In today's society, science and technology are advancing by leaps and bounds, and the global economy is developing rapidly. People's requirements for the quality of industrial equipment, machines, and buildings are getting higher and higher. More and more metal materials are widely used in construction, petroleum, aerospace, pipelines, etc. . However, when they serve in various environments, they will inevitably cause corrosion. Equipment failure and machine stoppage caused by corrosion of metal materials will cause huge accidents. Especially in the equipment for desulfurization and denitration treatment, the corrosion of sulfuric acid and nitric acid exists for a long time, which accelerates the aging and failure of pipelines. [0003] The damage caused by the chemical and electrochemical interaction betwe...
