Abstract
The invention discloses a kind of preparation method of antibacterial anticorrosion waterborne epoxy coatings, colloidal sol is passed through esterification by the present invention, ammonification, amidatioon is handled, effectively improve the dispersiveness of colloidal sol in the epoxy, improve the compatibility of titanium dioxide and each raw material, effectively reduce reunion, enhance the uniform and stable property of coating, surface strength and bacteriostasis property, colloidal sol esterification is improved into the lubricity and dispersiveness of coating, lanolin that the coating of the present invention is added etc. can effectively improve the antiseptic property of film, the dope viscosity of the present invention is high, caking property with base material is strong, antibacterial intensity is high.
Description
Technical field
The invention belongs to paint field, and in particular to a kind of preparation method of antibacterial anticorrosion waterborne epoxy coatings.
Background technology
Epoxy resin is used in anticorrosive coating with liquid resin portion maximum, but the coating industrially used at present
Major part is solvent based coating, and conventional solution-type coating is more using aromatic hydrocarbons, esters, alcohols, ketone etc. as solvent, and these solvents are equal
With different degrees of toxicity, and volatile matter is directly discharged into air, and environmental pollution is heavier.With the increasing of people's environmental consciousness
By force, the novel anticorrosion coating such as green such as powdery paints, solventless coatings and water paint without organic solvent or low VOC
Coating is developed in succession.Powdery paints is more harsh because of condition of cure, so as to limit its development；Solventless epoxy coating exists
Solvent free paint field be comparison successfully, simply in recent years reactive diluent hypotoxicity and curing agent it is safe and reliable
It is challenged in terms of property, among improving；And waterborne epoxy coatings is in addition to the plurality of advantages for adhering to solvent based coating,
Develop in terms of improving performance, reduce pollution, expansion application, oneself covers locomotive, aviation, food, building etc. in its field,
Therefore waterborne epoxy coatings is to develop a very rapid field in recent years；
