Water-based environment-friendly epoxy anticorrosive primer and method for preparing same

Abstract

The invention discloses water-based environment-friendly epoxy anticorrosive primer and a method for preparing the same. The water-based environment-friendly epoxy anticorrosive primer comprises water-based epoxy resin emulsion, fluorine-carbon emulsion, fillers, antirust pigment, deionized water, silane coupling agents, preservatives, ketimine resin, water-based epoxy curing agents, scale mica powder, titanium dioxide powder, dispersing agents, accelerators, leveling agents, defoaming agents, wetting and dispersing agents, talc powder, fatty amine, penetrating agents, glutinous rice powder, rhizoma bletillae, poria, folium artemisiae argyi and centipeda minima. The water-based environment-friendly epoxy anticorrosive primer and the method have the advantages that the water-based environment-friendly epoxy anticorrosive primer can be dried quickly and is good in anticorrosive and antirust property and heat-resistant stability, low in VOC (volatile organic compound) emission, high in adhesion stress and strength and free of pollution and heavy metal such as chromium; traditional Chinese medicine components of the rhizoma bletillae, the poria, the folium artemisiae argyi and the centipeda minima are further added into the water-based environment-friendly epoxy anticorrosive primer, can be continuously emitted to indoor environments after the water-based environment-friendly epoxy anticorrosive primer is used, and can be transmitted into human bodies via the respiratory tracts, the skins and the mucosas, the water-based environment-friendly epoxy anticorrosive primer has fresh and cool smell, and air purification, antibacterial and sterilization effects can be realized by the water-based environment-friendly epoxy anticorrosive primer.

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.
