Abstract

The invention relates to a high-performance water-based bicomponent epoxy zinc rich primer and a preparation method thereof. A water-based bicomponent epoxy zinc rich coating A in the high-performancewater-based bicomponent epoxy zinc rich primer comprises a water-based epoxy curing agent, an additive A, a complex solubilizer, zinc powder, zinc and an anti-settling agent; a water-based bicomponent epoxy zinc rich coating B comprises a water-based epoxy emulsion and an additive B; the weight ratio of the coating A to the coating B is at 100 to (10-30). The preparation method comprises the following steps: (1) uniformly mixing the components in the coating A at ratio and using a 100-mesh screen for filtering; (2) uniformly mixing the components in the coating B at ratio; and uniformly mixing the coating A with the coating B at the weight ratio in a use process and regulating the construction viscosity. When the high-performance water-based bicomponent epoxy zinc rich primer is used, water is taken as a solvent, so that the use of the organic solvent is greatly reduced and the environmental protection is benefited. The collocation of the anti-settling agent is utilized to solve the problems of storage and construction.

Description

technical field [0001] The invention relates to a high-performance water-based two-component epoxy zinc-rich primer and a preparation method thereof, belonging to the technical field of water-based anticorrosion coatings. Background technique [0002] At present, most of the existing epoxy zinc-rich coatings are solvent-based, which contain a lot of organic solvents and cause great environmental pollution. Water-based zinc-rich epoxy greatly reduces the use of organic solvents and meets environmental protection requirements; in the prior art, many water-based two-component epoxy zinc-rich coatings have unsatisfactory anti-settling effects, and the solvents used, such as propylene glycol butyl ether, are highly carcinogenic Solvents are very harmful to the human body. [0003] Chinese patent 201310192419.7 discloses a high-performance and easy-to-apply two-component water-based epoxy zinc-rich coating and its preparation method. The patent includes component A and component ...
