Polymerization inhibiting coating layer, preparation method thereof, and applications of polymerization inhibiting coating layer in styrene monomer storage tanks

The invention belongs to the technical field of hydrocarbon stabilization, and more specifically relates to a polymerization inhibiting coating layer, a preparation method thereof, and applications ofthe polymerization inhibiting coating layer in styrene monomer storage tanks. The polymerization inhibiting coating layer comprises a bottom layer, a middle layer, and a surface layer; each layer isprepared from a raw material containing a base material, and an auxiliary material or a curing agent; the base materials are prepared from epoxy resin and alcohol amine auxiliary materials; the base material of the middle layer contains a polymerization inhibitor; the surface layer auxiliary material or the curing agent contains a dispersant. According to the preparation method, the polymerizationinhibitor formula and the coating material formula are changed, coating layer preparation conditions are mild, energy consumption is low, the cooperative effect of the polymerization inhibitor with the dispersant is capable of
