Problems solved by technology

Most of the products currently on the market tend to improve the functional groups of water-based epoxy resin emulsions and water-based epoxy resin emulsion curing agents. Although the performance of coatings has been improved to a certain extent, the disadvantage of poor weather resistance of epoxy resins is still very prominent.

Abstract

Composite nanometer waterborne anticorrosive paint comprises a component A and a component B. The component A is made from deionized water, wetting dispersant, defoamer, nanometer titania, ferrotitanium powder, pigment, filler, waterborne epoxy resin emulsion, flatting agent, thickening agent, waterborne fluorocarbon resin emulsion, preservative and coalescing agent according to a ratio. The component B is waterborne epoxy hardener. The waterborne epoxy resin emulsion and the waterborne fluorocarbon resin emulsion are mixed through condition control, F-C bonds are distributed on the coating surface, a prepared coating has the advantages of high weather resistance, corrosion resistance and adhesive force and the like, and the defect of low weather resistance of epoxy resin coatings is overcome thoroughly. The paint can be used individually and can also serve as primer or finish to be used together with other paint.

Description

technical field [0001] The invention relates to coatings, in particular to a composite nano water-based anti-corrosion coating and a preparation method thereof. Background technique [0002] With the gradual improvement of society's requirements for environmental protection, people began to tend to use low-VOC or VOC-free environmentally friendly coatings. Waterborne epoxy resin coating has become a key research object because of its low cost and wide application range. Most of the products currently on the market tend to improve the functional groups of water-based epoxy resin emulsions and water-based epoxy resin emulsion curing agents. Although the performance of coatings has been improved to a certain extent, the disadvantage of poor weather resistance of epoxy resins is still very prominent. . Contents of the invention [0003] The object of the present invention is to provide a composite nano water-based anti-corrosion coating and a preparation method thereof in or...
