Background
Concrete laitance is the loose and soft layer material that the bleeding caused when cement hardens floats on the casting material surface, and the intensity of laitance is less than the concrete body greatly, in order to guarantee that concrete surface construction coating has good adhesive force in engineering application, all need polish totally with the laitance. The working strength of the floating slurry polishing is high, the efficiency is low, and the coating construction efficiency is greatly reduced. In order to reduce the grinding amount of the laitance and even construct the coating without grinding, the concrete laitance is treated and strengthened by adopting a concrete surface treating agent or an interface agent, which is a current solution.
Thermoplastic copolymer emulsion or silane surface treating agent is generally adopted in the prior art for treating the surface of concrete. The small molecular structure of the silane can penetrate through the curdling surface and penetrate into the concrete, so that the laitance is more compact, and the cohesive strength of the laitance and the body is enhanced; the copolymer emulsion has excellent permeability, can fully infiltrate the surface of a wall body base material, enables the base layer to be compact through crosslinking, improves the interface adhesive force, and improves the bonding strength of the wall body surface.
However, after the silane surface treating agent is adopted for treatment, the surface of the concrete has hydrophobicity, so that the interlayer wetting capacity of the subsequent coating is reduced, the subsequent coating is easy to generate poor adhesion, and the interlayer adhesion is less than 1.5 MPa; the copolymer emulsion is thermoplastic, has low heat resistance, can generate thermal creep shrinkage when changing at high and low temperatures, and does not meet the use requirements of high-temperature resistant scenes, for example, the coating used in the nuclear protection field is required to resist 120 ℃.
