Abstract

The invention belongs to the technical field of iron product treatment and particularly relates to a rust-proof treatment method for an iron product. The rust-proof treatment method comprises the following specific steps of (1) pretreatment of the iron product; and (2) rust-proof treatment of the iron product. The process is simple, and toxicity and harm are avoided; pretreatment is conducted firstly, water and oxygen are effectively isolated, infiltration of the water and the oxygen is effectively inhibited, thus a generated protective film is high in adhesion ability, and good rust-proof performance is presented; and then rust-proof treatment is conducted, rust-proof components are stable, and molecules can be effectively adsorbed on the metal surface; and a compact protective layer can be formed, the rust-proof ability is good, a film layer is attractive and glossy, durability and abrasion resistance are good, falling off, cracking and foaming are avoided, the cleaning effect is effectively improved, the service life of the iron product is prolonged, and the use quality of the iron product is improved.
