Abstract

The invention relates to the technical field of coatings, and provides an epoxy glass flake coating that can be cured underwater and a preparation method thereof, wherein the coating includes component A and component B, and component A includes bisphenol A epoxy resin and a reactive diluent , thixotropic agent, water remover, coupling agent, butyl phthalate and glass flakes; component B includes curing agent, pigment and filler, thixotropic agent and liquid petroleum resin; curing agent is made of modified polyamide and modified The active hydrogen equivalent of the modified polyamide is 80-200, and the viscosity at 40°C is 3000-21000mPa.s; the active hydrogen equivalent of the modified phenalkamine is 70-120. The resin system provided by the present invention selects the bisphenol A epoxy resin system with good anticorrosion performance, and the curing agent has good flexibility and can be cured on a wet surface. Modified polyamide and modified phenolic resin with good anticorrosion performance and block reaction rate A combination of amines that improves wet surface cure and aids in the curing of coatings in underwater environments.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an underwater curable epoxy glass flake coating and a preparation method thereof. Background technique [0002] Epoxy glass flake coating has strong anti-corrosion performance, and is the first choice for heavy-duty anti-corrosion coatings in ports and wharves. The glass flakes added to the coating can effectively slow down H 2 O, Cl - Etc. penetration of the coating, prolonging the service life of concrete, steel and other components. [0003] In the process of port construction, in most cases, the facility components can be coated with glass flake anti-corrosion coating on the shore or in the factory building, and then hoisted and installed. However, some parts are located below the waterline due to factors such as the local natural environment and construction windows. If the conventional glass flake anti-corrosion coatings on the market are directly coated, on the one hand...
