The invention provides an antirust and anticorrosive emulsion which comprises the following components in parts by weight: 0.5-2 parts of reactive anionic emulsifier, 0.1-1.5 parts of reactive nonionic emulsifier, 3-5 parts of n-decyl methacrylate, 8-10 parts of PIB2300 polyisobutylene, 1-3 parts of divinylbenzene, 40-60 parts of methyl methacrylate, 2-5 parts of hydroxybutyl methacrylate, 0.5-3 parts of glycidyl methacrylate, 20-25 parts of butyl acrylate, 0.2-0.5 part of phytic acid, 0.25-0.5 part of initiator, 0.1-0.3 part of oxidant, 0.2-0.6 part of reducing agent, 0.15-0.8 part of pH regulator and 80-100 parts of deionized water; according to the invention, phytic acid is introduced, active hydrogen reacts with an epoxy group, and a phosphate group chelates with iron atoms on the surface of steel to form a compact antirust and anticorrosive protective layer, so that the corrosion resistance and the antirust performance of the coating are improved. |
