Abstract

The invention discloses a preparation method of a barium sulfate-calcium carbonate compound modified epoxy resin coating. The preparation method is characterized in that the compound modified epoxy resin coating is prepared by heating a graphene oxide dispersion liquid, adding p-phenylenediamine dropwise, stirring, dissolving, reacting at the constant temperature, filtering, centrifuging and washing with deionized water and absolute ethyl alcohol, drying to obtain a graphene oxide-p-phenylenediamine composite; stirring a barium sulfate suspension liquid in a thermostatic bath, adding a compound modifier, stirring, filtering while the mixture is hot, drying, grinding, and screening to obtain modified barium sulfate; drying calcium carbonate in a vacuum drying oven, adding a silane couplingagent and a titanate coupling agent, heating and modifying calcium carbonate through a dry method; mixing and stirring deionized water ultrasonic dispersion liquid of the graphene oxide-p-phenylenediamine composite and deionized water ultrasonic dispersion liquid of a waterborne epoxy resin, ultrasonically treating, layering, pouring out water, heating the mixed solution in the drying oven, mixingwith a waterborne epoxy hardener, ultrasonically stirring, adding an emulsifier, a dispersing agent, a defoamer and a wetting agent, and ultrasonically treating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method of barium sulfate-calcium carbonate composite modified epoxy resin coating. Background technique [0002] Traditional solvent-based anti-corrosion coatings have problems such as high porosity, poor hydrophobicity, and low coating strength. Doping nanoparticles in traditional coatings is a common method to reduce porosity, increase hydrophobicity, and improve coating strength. Graphene is a two-dimensional honeycomb carbon nanomaterial with large specific surface area, high density and chemical inertness, and has strong physical shielding performance against corrosive media. Doping graphene in organic coatings can effectively improve Corrosion resistance of coatings. However, graphene has low dispersion in coatings and is prone to agglomeration, resulting in pitting pits and destroying the coating structure. In order to improve the dispersibility of graphene, the p...
