Abstract

The invention belongs to the technical field of corrosion prevention, and provides a permeation corrosion inhibition type rusty antirust primer and a preparation method and application thereof. The toughness and impact resistance of a paint film are improved through the toughening resin, the coating performance of the primer under the damp working condition is enhanced through the low-surface-energy leveling agent, moisture in a rust layer can be replaced, moisture on the surface of a base material is promoted to migrate to the surface of the coating from the bottom of the coating, and the continuity of the coating and the adhesive force between the coating and the base material are improved. The permeability of the primer is improved through the penetrating agent, the primer is promoted to fully infiltrate and permeate into the porous rust layer, and the rust conversion performance is improved. Rust is converted into stable and useful filler through rust conversion resin with rust anda rust conversion agent, the attachment area of the primer and the metal base material is further increased, and the compactness of a paint film is improved. The permeation corrosion inhibition typerusty antirust primer provided by the invention can be coated on the surface of a wet rusty base material, and has the characteristics of good permeability, strong corrosion inhibition capability, high rust conversion capability, low surface treatment grade and synergistic long-acting protection.

Description

technical field [0001] The invention relates to the field of anti-corrosion technology, in particular to a penetration corrosion-inhibiting anti-rust primer with rust and its preparation method and application. Background technique [0002] Offshore facilities such as pipelines, storage tanks, and steel structures are prone to metal corrosion in harsh environments such as ocean high temperature, high humidity, and high salt spray. Therefore, it is necessary to apply an anti-corrosion coating to the surface to protect the surface and prolong the service life. Before the construction of anti-corrosion coatings, strict surface derusting treatment must be carried out. This is because rust is a porous, fluffy, constantly growing substance, which may also contain water and inorganic salts. If the rust layer on the surface is not removed and the anti-corrosion paint is directly applied, the quality of the paint film will first be reduced, and secondly, the metal will be damaged. ...
