Beschreibung
Zusammenfassung:	The invention relates to a preparation method of a leakage-point-free high-resistance anticorrosive coating, which comprises the following steps: preparing materials: preparing an aluminum profile to be coated; preparing a reaction solution, namely preparing the reaction solution with the zinc-alkali concentration of 6: 5; the aluminum profile reacts with the reaction liquid twice, the reaction time is 1 minute each time, and an oxide layer is formed on the surface of the aluminum profile through the reaction; mounting a nano-coating mold, and sleeving the nano-coating mold on the four sides of the aluminum profile; coating a primer layer, wherein the primer layer is directly coated on the surface of the reacted aluminum profile through a nano coating mold; coating a functional layer, wherein the functional layer is attached to the upper end of the primer layer; coating a finish paint layer, wherein the finish paint layer is attached to the upper end of the functional layer; and the nano coating mold is taken
