Abstract

The invention relates to a preparation method of an epoxy glass flake coating for an oceanic tidal range/splash zone. The epoxy glass flake coating is composed of a component A and a component B, the component A contains low molecular weight epoxy resin, bisphenol F macromolecular epoxy resin, an epoxy active diluent, hydrogenated liquid petroleum resin, a solvent, an antifoaming agent, an antirust pigment, a coupling agent, a composite functional thixotropic agent, modified glass flakes and a modified filler, and the component B contains an amine composite curing agent and the coupling agent. The preparation method comprises the following steps: confirming the composition and weight part proportions of all raw materials, preparing the composite functional thixotropic agent, preparing the modified glass flakes, preparing the modified filler, preparing the amine composite curing agent, preparing the component A, preparing the component B, and blending the component A with the component B in proportion to prepare the epoxy glass flake coating. The epoxy glass flake coating has the advantages of high solid content, low viscosity, small use amount of the organic solvent, and great reduction of the volatilization of VOCs in the production, construction and curing process of the coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a preparation method of epoxy glass flake coatings for ocean tidal range / splash areas. Background technique [0002] The marine environment is a harsh corrosive environment, in which the corrosion rate in the tidal range / splash area is the highest, and the average corrosion rate in the tidal range / splash area is 3 to 10 times higher than other corrosions. Therefore, the anti-corrosion coating in the tidal range / splash area should not only have excellent anti-corrosion performance, but also have higher wear resistance. [0003] In order to effectively slow down corrosion, coating with ultra-high film thickness is generally used, and the film thickness is often greater than 1000 μm. In some tidal range / splash areas, the film thickness even reaches 3-5 mm. Due to the increase of film thickness, the curing process is increased. The internal stress also increases sharply, leading to...
