Preparation technology of on-rust antirust heavy duty anticorrosion paint

Abstract

The invention relates to a preparation technology of on-rust antirust heavy duty anticorrosion paint and belongs to the technical field of on-rust antirust heavy duty anticorrosion paint preparation. The preparation technology comprises the following steps of 1, stirring, 2, grinding, 3, dispersion, 4, resin preparation, 5, paint preparation and 6, stirring. The preparation technology has simple processes and can produce the paint with high permeability, high solid content and low viscosity. The paint can go through a rust layer and passivate active and harmful iron compounds in the rust layer into a harmless filling material.

Description

technical field [0001] The invention relates to a preparation process of a rust-resistant anti-rust heavy-duty coating, belonging to the technical field of preparation technology of rust-resistant anti-rust heavy-duty coatings. Background technique [0002] At present, many industries require a large number of anti-corrosion projects, many of which cannot be painted in a state of complete rust removal, because rust is a loose, porous, and constantly developing (expanding) substance, which may contain If water and inorganic salts are not removed and painted on the steel surface, the metal will continue to undergo electrochemical reactions in the presence of water and inorganic salts to generate new rust, destroy the surface paint film, and cause the paint to lose its protective effect on the metal. . [0003] In order to obtain excellent corrosion resistance, the surface treatment of its steel structure is a very important link. The rust on the substrate must be removed bef...

Problems solved by technology

This method is to add an integrating agent to the paint. The same problem is that the content of the metal rust and the form of the rust are different, and it is difficult to determine the amount and type of the integrating agent.
