The invention discloses an ultralow-temperature curable
epoxy anticorrosive
coating. The ultralow-temperature curable
epoxy anticorrosive
coating is composed of a component A and a component B; the component A consists of film-forming resin, an auxiliary agent, filler,
pigment and deionized water, wherein the film-forming resin consists of 25-45 parts of
bisphenol F
epoxy resin and 20-40 parts ofsilane modified epoxy resin, the weight parts of the auxiliary agent are 2-4 parts, the filler comprises 15-25 parts of
nano silicon dioxide and 2-10 parts of lignocelluloses, the
pigment is 3-5 partsof
titanium dioxide, and the weight parts of the deionized water are 10-20 parts; and the component B is a curing agent and is composed of 3-10 parts of
phenolic amine, 2-5 parts of
ethylenediamine,2-5 parts of
polyamide and 5-10 parts of deionized water. Through the formula
system, climate tolerance of the
coating can be effectively improved,
cracking is prevented, and the coating has the advantages of good
corrosion resistance and relatively high
adhesive force. The used curing agent is a mixed curing
system taking the
phenolic amine as a main body, so that the
reaction speed of epoxy resin can be effectively accelerated, the curing
reaction temperature is reduced, and consumption of curing energy is reduced.
