Embodiment 1
[0062] A water-based epoxy phosphate zinc powder anti-rust paint, the anti-rust paint is composed of component A and component B in a mass ratio of 2:1:
[0063] 1) The component A includes the following components by mass percentage:
[0064]
[0065]
[0066] 2) The second component is water-based epoxy curing agent AB-HGF.
[0067] The preparation method is as follows:
[0068] 1) First, mix the water-based epoxy resin, dispersant, phosphate, zinc powder, sodium nitrite, and water according to the formula amount, and then disperse, and sand to a fineness of 70μm or less;
[0069] 2) Add the remaining additives to the mixture obtained in step 1) and stir evenly. After adjusting the viscosity to 3~5Pa.S, filter and pack to obtain component A;
[0070] 3) Pack the component A and component B obtained in step 2) according to the mass ratio.
Embodiment 2
[0072] A water-based epoxy phosphate zinc powder anti-rust paint, the anti-rust paint is composed of component A and component B at a mass ratio of 8:1:
[0073] 1) The component A includes the following components by mass percentage:
[0074]
[0075]
[0076] 2) The second component is water-based epoxy curing agent AB-HGT.
[0077] The preparation method is the same as in Example 1.
Embodiment 3
[0079] A water-based epoxy phosphate zinc powder anti-rust paint, the anti-rust paint is composed of component A and component B at a mass ratio of 8:1:
[0080] 1) The component A includes the following components by mass percentage:
[0081]
[0082] 2) The second component is water-based epoxy curing agent AB-HGT.
[0083] The preparation method is the same as in Example 1.
