Abstract

The invention relates to a concrete-curing agent applicable to a strong-wind arid area and a preparation method thereof. The curing agent is prepared through the following steps of: by using an organic / inorganic composite system with an organic-silicon / fluorine modified propyl-benzene emulsion and active aluminum-silicate modified sodium-silicate solution as a main fluid and adopting a siloxane organic-silicon compound with a certain reactive group as a cross-linked component, compounding with a film-forming aid, a defoaming agent, a thickening agent, a wetting and dispersing agent, a mildew-proof agent, a flatting agent, an ultraviolet-resisting agent and deionized water under the condition at a normal temperature. The production process of the concrete-curing agent is simple, and reaction conditions are easy to control. The water-resisting property, the scrubbing-resisting property, the durability and the flexibility of a film after the film of the curing agent is formed are improved by introducing the propyl-benzene emulsion of organic silicon / fluorine onto a high-molecular chain; and the compactness of the film is enhanced by introducing the modified sodium-silicate solution, thereby the water evaporation of a concrete surface is greatly reduced. The curing agent has the technical characteristics that the curing agent can be sprayed after concrete is finished, the film-forming speed is high, the water retention rate is high, ultraviolet rays are resisted, and the like, and is applicable to the concrete curing of western strong-wind arid areas.

Description

[0001] Technical field: The present invention relates to building materials, in particular to a concrete curing agent suitable for strong wind and dry areas and its preparation method. Background technique [0002] Conservation is an important link in the process of concrete construction, which directly affects the mechanical and durable properties of concrete and the service life of structures. First of all, the strength of concrete comes from the hydration of cement. Good maintenance prevents the rapid evaporation of water, ensures the water needed for cement hydration, and at the same time inhibits the occurrence of early shrinkage cracks, significantly improving the durability of concrete; secondly, reasonable The maintenance will reduce the weak interface between the aggregate inside the concrete and the cement slurry, reduce the permeability of the structure to a certain extent, and prolong the service life of the concrete. The traditional maintenance method is to ensure...
