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.
