Description
Technical field
The invention belongs to concrete curing agent technical field, relate to cement concrete curing agent, especially relate to a kind of moisturizing insulating cement curing compound and preparation method thereof.
Background technology
Concrete, as the material that consumption is maximum in the world at present, has irreplaceable effect in engineering.And concrete technology is systems engineering, from proportion design, stirring, transport, build, vibrating to maintenance links is closely connected, any one link goes wrong all to produce concrete quality and have a strong impact on.Concrete precuring is the important step that concrete quality ensures, if the improper concrete drying shrinkage that will cause of precuring causes cracking, surface dehydration makes aquation deficiency affect concrete strength and weather resistance, the excessive generation that also will speed up crack of internal-external temperature difference.Therefore, the guarantee of effective concrete pouring way to construction quality seems very necessary.
Concrete curing method conventional in current engineering: cotton-wadded quilt moisture-heat preservation cladding process, pad pasting method of curing, geotextile wrap watering method and automatic spray method.These methods are time-consuming, take a lot of work and produce serious water resource waste.Therefore, carry out maintenance with effective curing compound and develop into important maintenance means.Cement concrete curing agent is that one is sprayed or painting way, forms the material of the continuous fluid-tight curing in airtight condition film of one deck at cement concrete surface.
Current curing compound is divided into organic type and the large class of inorganic type two.Organic type curing agent refers to that macromolecule material film molecule aggregation after moisture drying evaporation becomes fluid-tight polymer thin film to cover cement concrete surface, stops the evaporation of moisture content, reaches the effect of moisturizing, mainly comprise: resene, latex class and emulsion class.Resene is usually containing volatile solvent, and contaminate environment is also detrimental to health; Latex type curing agent exists that cost is high, maintenance terminates rear film forming and is difficult to remove, affect the problems such as successive projects progress; Emulsion class advantage is comparatively obvious, but also there is the problems such as coating thickness is little, film forming compactness is poor, unit mass spray area is little.Inorganic type curing agent is mainly silicate solutions class, reduces the speed of water evaporates by strengthening dense surface, but it can not film forming, and water retention is not enough.
Chinese patent CN 103253985 B discloses a kind of composite cement curing compound and preparation method thereof, although film forming is fine and close, good water-retaining property, use epoxy resin is as coating, and cleaning is complicated.
Chinese patent CN103058544 B discloses a kind of Concrete Double component curing agent, owing to adopting two component film forming, must carry out twice spraying, will increase hand spray expense.
Chinese patent CN 102976652 B discloses emulsion curing agent of a kind of high water retention and preparation method thereof.Although what adopt is nucleocapsid structure, owing to being solid core shell structure, not there is effect of heat insulation, and high expensive.
In sum, although current curing compound kind is a lot, water-retentivity also meets the requirements, and does not generally possess heat-proof quality, causes coating amount comparatively large and makes cost higher.
