Description
Technical Field
The invention belongs to the technical field of paint preparation processes, and particularly relates to an anticorrosive paint for an aerated plate built-in steel bar net cage and a preparation method thereof.
Background
The aerated concrete is a material with a porous structure, a plurality of micro air holes with the diameter of 1-3mm are formed in the aerated concrete, a hole solution is alkaline, the corrosion of the steel bar is easily caused in the processes of autoclaved maintenance and use, the corrosion on the surface of the steel bar is divided into chemical corrosion and electrochemical corrosion, the chemical corrosion is the corrosion caused by the contact of the surface of the steel bar and gas or a gas medium solution, and the corrosion does not have the flow of electrons and is only a small part of the corrosion phenomenon; the electrochemical corrosion is corrosion caused by electrochemical reaction between the surface of the steel bar and a corrosion medium, and most of the corrosion belongs to the electrochemical corrosion, so that the influence of the electrochemical corrosion on the aerated concrete slab is mainly considered.
The condition of electrochemical corrosion on the surface of the steel bar is that when moisture exists on the surface of the steel bar, an anode reaction of iron ionization and a cathode reaction of solution state oxygen reduction occur and are carried out at equal speed, and the reaction equation is as follows:
anode Fe → Fe2+ +2e-Cathode 0.5O2 + H2O+2e-→ 2OH-
Fe2++2OH- →Fe(OH)2 Fe(OH)2+0.5H2O+0.25O2→ Fe(OH)3
Resulting Fe (OH)3Further oxidized to form red rust Fe2O3Partial incomplete oxidation to form black rust Fe3O4. The volume of the corroded steel bar is 2-6 times of that of the corroded steel bar, and the aerated concrete slab can crack due to volume expansion, and the aerated concrete protective layer falls off in severe cases. The protective action on the steel bars is further degraded after the aerated concrete slab cracks, and a corrosive medium is easier to contact the steel bars, so that the corrosion is further aggravated, the structural damage of the aerated concrete slab is accelerated, and the structural durability is reduced. Meanwhile, the bonding force between the corroded steel bar and the aerated concrete is reduced, the foundation of cooperative work of the steel bar and the aerated concrete is damaged, and the reliability of the structure is reduced. Thus being developed and adapted for aerated mixesThe special anticorrosive coatings for the application systems of the panels have become the key to solving the above problems. However, the corrosion-resistant coating is limited by the influence of system environment and use environment factors, so that the influence factors of steel bar corrosion are more, and the problems of effective fusion of the corrosion-resistant coating, the steel bars and the aerated concrete matrix material and the like become the difficulty of the development of the corrosion-resistant coating.
