Abstract

The invention discloses a low-viscosity solvent-free epoxy graphene glass-flake coating and a preparation method thereof, and aims to solve the problems that the conventional solvent-free epoxy graphene glass-flake coating has a high requirement on a construction thickness, is not ideal in corrosion resistance, needs to apply heating spraying and has a large number of coating working procedures. The coating consists of two components specifically as follows: the component I is prepared from the following raw materials in percentage by mass: 37 to 40 percent of epoxy resin E51, 2 to 4 percent of an active diluents NC513, 0.2 to 0.6 percent of a dispersing agent BYK-9077, 15 to 23 percent of functional resin 312, 14 to 15 percent of titanium dioxide R2196, 20 to 25 percent of glass flakes, 0.2 to 0.3 percent of graphene, 0.2 to 0.5 percent of a rheological agent BYK-410, 0.2 to 0.4 percent of a leveling agent F40 and 0.2 to 0.6 percent of a defoaming agent 6800; the component II is prepared from the following raw materials in percentage by mass: 75 to 94 percent of a curing agent CK-5106, 5.6 to 24.2 percent of a curing agent D0590, 0.2 to 1.5 percent of graphene and 0.2 to 1.0 percent of the dispersing agent BYK-9077. The coating can be directly used for coating by a conventional construction process without being heated, and the construction is rapid, simple and convenient.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a solvent-free epoxy glass flake paint. Background technique [0002] With the continuous improvement of anti-corrosion requirements for coatings in the heavy-duty anti-corrosion industry, epoxy glass flake coatings are widely used in harsh corrosive environments such as marine anti-corrosion and petrochemical anti-corrosion due to their excellent shielding properties. [0003] Epoxy glass flake coating is a two-component coating, with bisphenol A epoxy resin and amine curing agent as the main reaction film-forming material, providing excellent corrosion performance and adhesion. Add flaky glass flake material to the epoxy resin, add additives and organic solvents, mix it with another component of amine epoxy curing agent in a certain proportion, and coat it on the surface of the coated substrate to form a continuous protective film. Corrosive factors such as salt, w...
