The invention discloses a water-based two-component epoxy paint, which is composed of a water-based two-component epoxy paint component A and a water-based two-component epoxy curing agent component B. The invention also discloses a preparation method of the water-based two-component epoxy paint. Through the anodic protection mechanism of an anticorrosive pigment, and a proper epoxy curing agent and diamino organosiloxane are matched, so that the compactness and adhesive force of paint film are improved, and the protection performance of coating layers on metal substrates is improved. 本发明公开了一种水性双组分环氧漆，由水性双组分环氧漆A组分和水性双组分环氧固化剂B组分组成。本发明还公开了其制备方法。本发明通过防腐颜料的阳极保护机理，搭配合适的环氧固化剂和双氨基有机硅氧烷，提高了漆膜致密性及附着力，提高了涂层对金属底材的防护性能。
