Preparation method of anticorrosive powder paint and product thereof

A preparation method of anticorrosive powder paint comprises the following steps: (1) preparing aromatic amino thiophosphoric acid from an aromatic amino intermediate; preparing n-propyl-6-ethyl hexyl phosphorodithioic acid from n-propyl-6-ethyl hexyl diol; and finally preparing a final product namely dialkyl aromatic amino zinc dithiophosphate from the prepared g aromatic amino thiophosphoric acid and n-propyl-6-ethyl hexyl phosphorodithioic acid in the presence of zinc oxide; (2) weighing a proper amount of modified epoxy resin (E-12) and phenolic expoxy resin (GT7255), grinding, adding a curing agent, an acrylate flatting agent, dimethyl imidazole, benzoin, flaky zinc powder, and the prepared ZADTP, finally adding a proper amount of auxiliary agents and filling materials, fully mixing, melting the mixture and then extruding by a gapless machine, grinding the extruded mixture with a high-speed universal grinder, and sieving so as to obtain the anticorrosive powder paint. The obtained anticorrosive powder pa
