Problems solved by technology

[0002] With the development of offshore oil exploration and development, platform construction has entered a period of rapid growth, and the amount of anti-corrosion coatings for steel structures has increased significantly. Most of the existing epoxy glass flake coatings are solvent-based, and the volatilization of solvents increases the porosity and shrinkage of the coating. Large, it is easy to form local stress concentration, which makes the coating brittle and reduces the adhesion, penetration resistance and impact resistance; when the coating is thick, the solvent is easy to stay inside the coating, affecting the compactness of the coating; the solvent content is high, environmental pollution

Abstract

The invention discloses a solvent-free epoxy glass flake coating and a preparation method. The coating is used for splash zones of offshore platform jackets to improve the anticorrosion capacity of steel pipes and prolong the service life of the steel pipes. The preparation method comprises the following steps of: adding a reactive diluent 660A into an epoxy resin, adding an organic bentonite rheological aid 881-B, an EP 2440 adhesion promotion resin, silicone oil, carbon black, titanium white and aluminum trippolyhosphate, mixing uniformly, grinding, adding glass flakes, and stirring uniformly to form solution A; forming solution B by using an epoxy curing agent H633; and mixing the solution A and the solution B to obtain the solvent-free epoxy glass flake coating during use. Solvents are not volatilized in the curing process, the coating is slightly shrunk, and the solvent-free epoxy glass flake coating has a compact structure and high permeability resistance; moreover, the solvent-free epoxy glass flake coating has extremely strong cohesive force and good anticorrosion performance.
