Description
Technical field
The invention belongs to paint fields, and in particular to a kind of flame retardant epoxy coating and preparation method thereof.
Background technology
Epoxy resin is used for coating maximum with liquid resin portion, but industrially using at present in anticorrosive coating
Major part is solvent based coating, and for conventional solution-type coating mostly using aromatic hydrocarbons, esters, alcohols, ketone etc. as solvent, 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, it is free of organic solvent or novel anticorrosion the coating such as powdery paints, solventless coatings and water paint etc. of low VOC is green
Coating is developed in succession.Powdery paints is because condition of cure is more harsh, to limit its development；Solventless epoxy coating exists
Solvent free paint field is that comparison is successful, only in recent years in the safe and reliable of the hypotoxicity of reactive diluent and curing agent
Property etc. is challenged, among improving；And waterborne epoxy coatings is other than the plurality of advantages for adhering to solvent based coating,
To improving performance, reducing pollution, expansion application etc. development, oneself covers locomotive, aviation, food, building etc. in field,
Therefore waterborne epoxy coatings is to develop a very rapid field in recent years；
For epoxy resin cured product because brittleness is big, impact resistance, resistance to acid and alkali, flexibility and temperature tolerance are poor, limit epoxy resin
The application of coating, therefore be always one of the emphasis studied anti-corrosive paint of epoxy resin to the modification of epoxy resin, and in order to
Its mechanical property is improved, is often added the inorganic fillers such as various bentonites, graphene wherein, but these inorganic fillers and ring
The compatibility of oxygen resin is poor, and the bin stability for be easy to causeing coating is poor, and is easy to form caking, reduces the product of coating
Matter.
