Embodiment 1

[0029] The preparation technology of one-component band rust coating comprises following technological process:

[0030] 1. Stir

[0031] Put the additives and solvents into the mixer for high-speed stirring. The linear speed of the mixer is controlled at 15-25m / s. After stirring for 5-15 minutes, add pigments and special pigments. The mass ratio of additives, solvents, pigments, and special pigments It is (0.1-3):00-30):(6-40):(8-15), mixing and stirring for 15-60 minutes; among them, the additive is dispersed by water remover, integrating agent, polycarboxylate Agent, silicone defoamer, and modified clothing anti-settling agent are mixed according to the mass ratio of (0.6-1.1):(0.3-7):(0.3-0.5):(0.1-0.15):(0.2-0.5) ;

[0032] The dewatering agent is any one or a mixture of oxazolidine and calcium oxide; the integrator is calcium polyphosphate, cyanotriacetic acid, monoammonium citrate, hydroxyethylethylenediaminetriacetic acid, hydrolyzed polymalay Any one or several mix...

Embodiment 2

[0051] The preparation technology of two-component band rust paint, its difference with embodiment 1 is:

[0052] 4. Preparation of resin

[0053] The preparation of ZY-2 resin: reacting heterocyclic compound, acrylic resin and epoxy resin according to the mass ratio (10-30):(20-80):02-30) to form an interpenetrating network to construct a new polymer resin that is Acrylic modified epoxy interpenetrating network polymer resin, the reaction temperature is controlled at 80-210°C, and the reaction time is 220-320 minutes, in which the heterocyclic compounds are lactone compounds, lactam compounds, internal acid anhydride compounds, pyridines Any one or a mixture of two or three of compounds, pyrrole compounds, and furan compounds;

[0054] 5. Coating preparation

[0055] Add ZY-2 resin, that is, acrylic modified epoxy interpenetrating network polymer resin and antirust and rust remover, to the mixture obtained in step 3 successively to prepare the coating. The mass ratio of the...

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...
