Abstract

The invention provides a water-based epoxy anti-corrosion primer for containers and a preparation method thereof. The water-based epoxy anti-corrosion primer is composed of component A and component B with a ratio of 12:1 by weight. Parts include epoxy resin emulsion, water-based functional emulsion, functional barrier filler, talc powder, anti-rust pigment, coloring pigment, dispersant, wetting agent, film-forming aid, thickener, defoamer and purified water; Component B includes water-soluble modified amine curing agent, anti-flash rust agent and purified water. The epoxy emulsion is modified by water-based functional emulsion, which not only improves the adhesion to the substrate, but also improves the drying and water resistance of the paint film. The addition of functional shielding fillers enhances the shielding effect of the paint film and significantly improves the anti-corrosion performance of the paint film. The water-based epoxy anti-corrosion primer of the present invention is a water-based paint product with low VOC content, can be diluted with water, is healthy and environmentally friendly, and at the same time, the paint film dries quickly, has good adhesion and excellent anti-corrosion performance.

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 ...
