Example Embodiment

[0016] figure 1 It is a process step diagram of the preparation method of the new waterborne epoxy anticorrosive coating in the embodiment of the present invention; the anticorrosive coating is prepared by mixing the A component let down and the B component curing material. The preparation method includes the following steps: a) Preparation Take the A-component color paste, b) prepare the A-component letdown, c) prepare the B-component curing material, and d) mix the A and B components to prepare the coating.

[0017] The new water-based epoxy anticorrosive coating mentioned in the present invention uses water-based epoxy resin emulsion and water-based modified amine curing agent as base materials, and uses suitable film-forming additives, dispersants, defoamers, leveling agents and other additives. The active anticorrosive pigment compounded by aluminum tripolyphosphate and zinc phosphate is used for preparation. The prepared waterborne epoxy anticorrosive coating has good envir...

Abstract

The invention provides a novel water-based epoxy anticorrosive coating and a preparation method thereof. The anticorrosive coating is prepared by mixing a component A mixed paint with component B curing materials. The preparation method comprises the following steps of: a) preparing a component A color paste; b) preparing a component A mixed paint; c) preparing component B curing materials; and d) mixing the components A and B, thereby obtaining the coating. According to the novel water-based epoxy anticorrosive coating and the preparation method thereof disclosed by the invention, the anticorrosive coating is excellent in environmental friendliness; and according to proper ingredients and amount ratios, the anticorrosive property of the coating is greatly improved, and the anticorrosive coating has high market application value.

Description

technical field [0001] The invention relates to a coating, in particular to a novel water-based epoxy anticorrosion coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Coatings are applied on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. Coatings generally contain four basic components: film-forming substances, pigments, solvents and additives. As a class of modern multifunctional engineering materials, coatings are widely used. At present, my country's coatings industry is developing in three directions: environmental protection, economy, and high performance. It is vigorously developing low-content solvent, water-based and solvent-free, powder, and UV-curable coatings. In recent years, my country's coating industry has been committed to the development of low pollution, high solids or solvent-free coatings, water-based...
