Water-based environmentally-friendly epoxy anti-corrosion primer and preparation method thereof

Abstract

The invention discloses water-based environmentally-friendly epoxy anti-corrosion primer and a preparation method thereof. The water-based environmentally-friendly epoxy anti-corrosion primer comprises water-based epoxy resin emulsion, fluorocarbon emulsion, filler, rust-proof pigment, deionized water, a silane coupling agent, preservative, ketimine resin, water-based epoxy hardener, flake mica powder, titanium dioxide, a dispersing agent, accelerator, a flattening agent, a defoaming agent, wetting dispersant, talcum powder, fatty amine, a penetrating agent, sticky rice powder, rhizoma bletillae, poria, folium artemisiae argyi and herba centipedae. The water-based environmentally-friendly epoxy anti-corrosion primer is high in drying speed, good in corrosion resistance and rust resistance, good in heat-resistant stability, low in VOC emission, good in binding power, high in strength, free of heavy metal such as chromium and free of pollution; traditional Chinese medicine components including the rhizoma bletillae, the poria, the folium artemisiae argyi and the herba centipedae are further added, after the water-based environmentally-friendly epoxy anti-corrosion primer is used, the traditional Chinese medicine components can be emitted continuously towards a room and enter the human body through the respiratory tract, the skin and the mucosa, the smell is fresh, and air purifying and antibacterial and bactericidal effects are achieved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly paints, in particular to a water-based environment-friendly epoxy anticorrosion primer and a preparation method thereof. Background technique [0002] At present, most of the anti-corrosion coatings in submarines and various ship cabins in my country use traditional solvent-based coatings. In order to obtain better anti-corrosion effects, chromium-containing anti-rust pigments are generally added to the existing epoxy anti-corrosion primers. , such as chromate containing hexavalent chromium, to improve anti-corrosion performance, but its toxicity is relatively high, which will cause great harm to the marine environment and human health. Disclosed two-component anticorrosion paint as Chinese patent application publication CN101457116A, CN100526406C, have adopted zinc yellow, chrome yellow, strontium yellow, zinc phosphochromate etc. Harmful to human body, especially hexavalent chromium...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few water-based paints used for the interior of the cabin. The primer is generally made of paint, while the top coat is mainly water-based alkyd and water-based acrylic, and the water-based epoxy paint that combines the bottom and surface has not been reported.
