High solid content damp and heat-resistant salt fog-resistant anticorrosive coating with wet and rust and preparation process thereof

The invention discloses a high solid content damp and heat-resistant salt fog-resistant anticorrosive coating with wet and rust and a preparation process thereof. The coating is prepared from a main agent and a curing agent in a ratio of 5: 1. The main agent of the coating is prepared from low viscosity epoxy resin, vinyl modified epoxy rusty resin, rust stabilizing anti-rust pigments and filler,a penetrant, a mixed solvent containing kerosene and small molecular alcohol, a defoaming/dispersing auxiliary agent and the like. The main agent is Bordeaux. The curing agent is prepared from cashewnut shell oil modified phenolic aldehyde and the like, and is brown. The solid content of the coating is greater than or equal to 72%. The coating has performance of extremely high adhesive force, excellent physical and mechanical properties and damp and heat resistance, salt fog resistance and the like, can be brushed normally when a grade D corrosion steel plate is derusted manually to St2 grade(the rust layer is smaller
