Abstract

The invention provides water-based epoxy anticorrosive primer for a container and a preparation method of the primer. The water-based epoxy anticorrosive primer is composed of an A component and a B component according to the weight ratio of the A component to the B component of 12:1; the A component includes an epoxy resin emulsion, a water-based functional emulsion, a functional shielding filler, talc powder, an anti-rust pigment, a coloring pigment, a dispersant, a wetting agent, a film-forming auxiliary agent, a thickening agent, a defoaming agent and purified water; and the B component includes a water-soluble modified amine curing agent, an anti-flash rust agent, and purified water. According to the primer provided by the invention, the epoxy emulsion is modified by the water-based functional emulsion, so that the dryness and water resistance of a primer film are improved while the adhesion to a substrate is improved; the functional shielding filler is added, so that the shielding effect of the primer film is enhanced, and the corrosion resistance of the primer film is significantly improved; and the water-based epoxy anticorrosive primer is a water-based paint product, has alow VOC content, is diluted by using water, and is healthy and environmentally friendly, and at the same time, the primer film is dried quickly, and has good adhesion and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the field of heavy anticorrosion, in particular to a water-based epoxy anticorrosion primer for containers. Background technique [0002] At present, the pace of container production is fast, and the drying speed of water-based epoxy primers is generally slow, resulting in poor corrosion resistance. Contents of the invention [0003] The object of the present invention is to provide a kind of waterborne epoxy anticorrosion primer with fast drying speed and excellent anticorrosion performance and its preparation method, so that it can adapt to the fast pace of container production and overcome the above-mentioned defects in existing products. [0004] In order to achieve the above object, the present invention provides a water-based epoxy anti-corrosion primer for containers, which is composed of A component and B component, and the A component includes epoxy resin emulsion, water-based functional emulsion, functional barrier ...
