Abstract

The invention discloses a waterborne epoxy anticorrosive antirust paint. With a waterborne epoxy elusion as a matrix, a plurality of pigment fillers and assistants, the waterborne epoxy anticorrosive antirust paint comprises a waterborne epoxy emulsion, water-based zinc phosphate, modified aluminum triphosphate, rutile titanium dioxide, a coalescing agent, a water-based defoamer, a thickener SN636, a wetting agent PE-100, a fungicidal preservative, a flash rusting agent, a dispersing agent 5040, a flatting agent and deionized water. The waterborne epoxy anticorrosive antirust paint is environmentally friendly; the raw materials are low in price; the preparation process is simple; meanwhile, the salt-water resistance is excellent; the adhesive force is high; and the flash rusting effect is good.

Description

technical field [0001] The invention belongs to the technical field of antirust paint, in particular to a water-based epoxy anticorrosion and antirust paint and a preparation method thereof. Background technique [0002] Traditional solvent-based antirust coatings mainly use organic solvents as the dispersion medium. Therefore, a large amount of organic compounds, namely Volatile Organic Composition (VOC for short), will volatilize in the process of preparation and use. The volatilization of VOC is a potential threat to the living environment and human health. On the other hand, the price of crude oil has risen sharply, which has forced the price of oil-based paints to increase continuously, and the cost of raw materials has also continued to increase. Therefore, scholars and researchers from various countries have gradually shifted their research focus from oil-based paints to water-based paints. [0003] Water-based coatings use water as a solvent (or as a dispersion me...
