Anticorrosive waterborne epoxy coating based on divalent zinc ions and phytic acid modified graphene oxide and preparation method of anticorrosive waterborne epoxy coating
The invention discloses an anti-corrosion water-based epoxy coating based on divalent zinc ions and phytic acid modified graphene oxide and a preparation method of the anti-corrosion water-based epoxy coating, and belongs to the technical field of anti-corrosion water-based epoxy coatings. The preparation method comprises the following steps: adjusting the pH value of a solution, selecting zinc nitrate hexahydrate and phytic acid as precursors, loading phytic acid functional groups and divalent zinc ions on graphene oxide, adding a modified graphene oxide filler into waterborne epoxy and a curing agent, mixing, and curing to obtain the waterborne epoxy coating. In a 3.5% wt. NaCl solution, compared with a blank waterborne epoxy coating, the corrosion resistance of the coating is improved by more than 5 times, the corrosion current density is reduced to an order of magnitude, and the chloride ion corrosion resistance of the coating is greatly enhanced. According to the graphene oxide loaded with phytic acid functional groups and divalent zinc ions, the dispersity of the graphene oxide in a water-based epoxy coating is improved, and the corrosion resistance of the water-based epoxy coating in a seawater environment is remarkably enhanced.

The invention discloses an organic substance bonding-type zinc powder and a preparation method thereof. The zinc powder is prepared from the following raw materials in parts by weight: 10 to 12 parts of spherical zinc powder, 2 to 6 parts of organic amine and 3 to 15 parts of water. The preparation method comprises the following steps: adding spherical zinc powder into an aqueous solution of organic amine in a reaction kettle, allowing reactions to take place for 20 to 40 min at room temperature or in a low temperature heating condition (35 DEG C to 60 DEG C), filtering, recovering the filtrate, washing the zinc powder until neutral, drying and grinding to obtain the final product of organic substance bonding-type zinc powder. According to the organic substance bonding-type zinc powder obtained by the preparation method, the physical shielding performance of spherical zinc powder is enhanced, the early corrosion prevention performance of spherical zinc powder coating is improved, the electric conductivity of the original zinc powder is not changed, and the overall anti-rust performance is improved. The preparation method has the advantages of no strict requirement for reaction conditions, simple process, convenience for operation and industrial production, recycling of the filtrate, low production cost, and good economic and social benefits.
