Description
Technical Field
The invention relates to the technical field of buildings, in particular to a concrete coating protection system and a construction method.
Background
The basic approach of the corrosion prevention of the reinforced concrete building structure is to improve the chloride ion permeability resistance of the concrete to the maximum extent through optimized design and construction so as to limit the penetration of environmental erosion media (chloride, oxygen, water and the like) into the concrete, thereby preventing the corrosion of reinforcing steel bars. The method mainly comprises the following steps: properly improving the strength of concrete and the using amount of cement, applying high-performance concrete, ensuring the thickness of a protective layer of steel bars, avoiding cracking or strictly controlling the width of the cracking, improving the compactness of the concrete, internally doping steel bar rust inhibitor, protecting an outer coating, coating (plating) steel bars, protecting cathodes and the like.
The concrete surface coating protection is the most effective and economic protection measure for concrete corrosion prevention. The protective coating is coated on the surface of the reinforced concrete structure, so that the infiltration of harmful media can be prevented, the alkalinity of the concrete can be kept, the protective coating is widely applied to the protection of various reinforced concrete structures, and the durability of the reinforced concrete structure can be improved under certain conditions. But has little effect on concrete members with micro cracks and can not meet the long-term durability requirement, particularly ocean engineering concrete structures. Cracks are inevitable in concrete materials, which is an inherent defect of cement-based materials. Therefore, the crack resistance and crack following performance of the concrete surface coating protective material become important indexes for testing the concrete coating protective material.
The concrete coating protective materials commonly used in the prior art include: epoxy resin coatings, chlorinated rubber coatings, acrylic coatings, polyurethane coatings, epoxy coal pitch coatings, coal tar pitch coatings, and the like. The materials have the defects of short protection life, high maintenance cost, poor environmental protection and the like. Particularly, when the concrete base layer cracks, the protective coating on the surface of the concrete base layer can crack along with the crack, and the protective effect is lost.
Chinese patent CN101456756A discloses a "heavy-duty anticorrosion nano composite coating for concrete structure and its protection method", which includes nano modified epoxy sealing paint, nano modified epoxy micaceous iron intermediate paint, nano modified fluorine-containing polyurethane finish paint or silicone-acrylate finish paint or fluorine-containing polysiloxane finish paint, to improve the adhesion and anticorrosion life of the protection system, but the flexibility is not described in detail, the protection system corresponds to the thickness and construction method of the traditional anticorrosion coating, and the improvement of the flexibility is determined to be limited according to the descriptions of the chemical composition and other properties of each layer of coating.
The Chinese application with the publication number of CN107337993A discloses a rapid-construction high-durability concrete protection system and a preparation method thereof, the protection system improves the construction efficiency and the environmental adaptability, but the tensile strength and the elongation of a reinforcing layer used as a main protection layer are still low, the tensile strength is 4.2-4.6 MPa, the elongation is 11-22%, the tensile strength of a surface layer is 12.5-13.8 MPa, and the elongation is 98-110%, so that once a base layer cracks, the risk that the protection coating cracks along with the base layer is still high.
Therefore, when the surface of a concrete building structure is coated and protected, a concrete coating and protecting system with excellent cracking resistance, durability, chloride ion permeability resistance and higher tensile strength and elongation is needed.
