Abstract

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.

Description

technical field [0001] The invention belongs to the field of anti-corrosion coatings for equipment, and in particular relates to a water-based two-component epoxy paint and a preparation method thereof. Background technique [0002] Traditional solvent-based two-component epoxy paints have been favored and widely used in the field of metal anti-corrosion due to their excellent anti-corrosion performance, low energy consumption characteristics of room temperature cross-linking, and wide application conditions. [0003] For example, engineering, agricultural transportation machinery, excavation machinery, concrete machinery, etc. in C1-C3 medium and low corrosion environments, as well as port terminals, bridges, ships, etc. in C4 and above environments, are all coated with epoxy coatings or related modifications. Paint as the main protective measure. With the vigorous implementation of my country's environmental protection policy, the demand for low-VOC coatings is becoming i...
