Abstract

The invention belongs to the field of epoxy resin coatings and particularly relates to a water-based flame-retardant epoxy resin coating. The water-based flame-retardant epoxy resin coating is prepared from a component A, a component B and a component C in a mass ratio being 5:1:1, wherein the component A is prepared from raw materials in parts by weight as follows: 90-100 parts of bisphenol A epoxy resin, 10-20 parts of polyoxyethylene alkyl ester and 10-25 parts of polyacrylic ester; the component B is prepared from raw materials in parts by weight as follows: 20-25 parts of triethylene tetramine, 3-5 parts of titanium dioxide, 8-10 parts of pigments, 100-110 parts of talcum powder and 30-40 parts of water; the component C is prepared from raw materials in parts by weight as follows: 1-3.2 parts of a wetting dispersant, 1.2-1.6 parts of a defoaming agent, 1.2-1.8 parts of a flatting agent, 15-20 parts of a phosphorus-nitrogen composite flame retardant, 5-6 parts of a hypophosphite flame retardant and 5-6 parts of phosphate. The epoxy resin coating has the advantages of being environment-friendly, high in film hardness, high in anti-impact strength, good in glossiness, good in flame retardance and the like.

Description

Technical field [0001] The invention belongs to the field of epoxy resin coatings, and specifically relates to a water-based flame-retardant epoxy resin coating. Background technique [0002] Epoxy resin coating is currently the world's most widely used, most widely applicable and most important heavy-duty anti-corrosion coating. Epoxy resin coatings are generally divided into oil-based epoxy coatings and water-based epoxy coatings. Waterborne epoxy anticorrosive coatings currently widely used in the market are mainly composed of two components: hydrophobic epoxy resin and hydrophilic amine curing agent. The formulation of water-based coatings is relatively complex, with many types of additives, and additives may affect the performance of the coating. [0003] At present, there are many related varieties of water-based epoxy resin coatings, which are widely used in cement product repair agents, waterproof coatings, automobile maintenance primers, and corrosion prevention of steel...
