Embodiment 1
[0020] The invention provides a kind of water-based epoxy anti-flash rust paint, which takes the following components by weight:
[0021] Water-based epoxy emulsion 99g,
[0022] Water-based curing agent 33g,
[0023] 45g of antiseptic pigments and fillers,
[0024] Anti-flash rust agent 2g,
[0025] Defoamer 0.1g,
[0026] Dispersant 0.1g,
[0027] Wetting agent 0.1g,
[0028] Wax powder 1g, mix the above components and stir evenly to get water-based epoxy anti-flash rust paint.
[0029] Further, the structural formula of described waterborne epoxy curing agent is as follows:
[0030] or Alternatively, R is polyethylene polyamine, m-phenylenediamine or m-xylylenediamine.
[0031] Further, the water-based epoxy emulsion is composed of bisphenol A epoxy resin, emulsifier, water, and surfactant, and the mass ratio of bisphenol A epoxy resin, emulsifier, water, and surfactant is 10 :1:10:1.
[0032] Further, the anti-corrosion filler is one or more of zinc powder, ...
