Problems solved by technology

[0003] At present, although the existing coatings on the outer surface of ships are environmentally friendly and safe to use, they are deficient in anti-corrosion performance, hardness, and solvent resistance, and have poor stain resistance and mildew resistance. It is easy to solidify in the environment, does not have the characteristics of anti-pollution, anti-condensation, anti-mildew and corrosion resistance, and cannot achieve the purpose of improving the environment of the interior cabin, preventing the growth of mildew in the cabin, and protecting the health of the personnel in the cabin.

Abstract

The invention relates to the technical field of waterborne epoxy anticorrosive coatings and discloses a self-emulsifying fluorosilicone-modified two-component waterborne epoxy anticorrosive coating. The coating comprises the following components: waterborne resin, waterborne epoxy ester resin, DPOMA, hollow glass beads, a coalescing agent, zinc phosphate, an antirust pigment, a pigment filler, aluminum triphosphate, xylene, a neutralizer, composite silicate rock slices, composite silicate fibers, graphene, a thickener, a defoaming agent, an initiator, an assistant, a pH regulator, a silica soland a cosolvent. After the waterborne epoxy ester resin, the hollow glass beads, the antirust pigment and the coalescing agent are proportioned according to desired parts in the invention, the waterborne epoxy anticorrosive coating has excellent mildew-proof and corrosion-resistant effects and the like, improves the environment of a cabin in a ship and protects the health of workers when appliedto painting of a ship surface.

Description

technical field [0001] The invention relates to the technical field of water-based epoxy anti-corrosion coatings, in particular to a self-emulsifying fluorine-silicon modified two-component water-based epoxy anti-corrosion coating. Background technique [0002] With the rapid development of my country's economy and the rapid improvement of people's living standards, the awareness of environmental protection in the whole society has also increased, and more and more attention has been paid to environmentally friendly new technologies and new materials. Applications in fields are on the rise, such as infrastructure, oil and gas and power industries, as well as industrial tanks, ships and chemical industries. [0003] At present, although the existing coatings on the outer surface of ships are environmentally friendly and safe to use, they are deficient in anti-corrosion performance, hardness, and solvent resistance, and have poor stain resistance and mildew resistance. It is e...
