Description

A kind of water-repellent preservation water-repellent paint for concrete structures
Technical field
The present invention relates to building material technical field, a kind of water-repellent preservation water-repellent paint for concrete structures.
Background technology
The structures built with concrete and reinforced concrete are frequently subjected to the erosion of corrosive medium during use.If constructed Anti-corrosion measure is not taked or do not implemented to structural material, when building, by thing, then Korrosionsmedium is it is possible to damage building structure, It is even made to lose use value.Especially in industrial structure, building structure may directly with carry mordant liquid, The medium contacts such as gaseous state, or corroded by the waste material of discharge in industrial products or commercial production, thus will cause structures The corrosion of structural material.If it addition, the additive improper use of concrete, construction quality existing problems or construction raw material are deposited In quality problems etc., these reasons all can cause armored concrete corrosion phenomenon occur.
In public projects such as municipal administration, water conservancies, concrete structures Anticorrosion Problems is progressively taken seriously, from being designed into Exploitation has begun to progressively consider the anti-corrosion treatment problem of concrete structures.But owing to the protection of current concrete erosion is produced Product are less, and therefore in prior art, the material that antiseptic concrete is used is mainly the solvent borne material used by iron structure anticorrosion Material or rigid material, such as solvent type epoxy series material, although these material antiseptic properties are excellent, but brittle, easily broken Bad, and, these materials mostly are thin material, and when being applied to concrete structures, the appearance surface self being difficult to avoid that lacks Fall into, such as blind crack, honeycomb, pitted skin, hole etc., cause these materials to be difficult on concrete structures surface and formed completely Continuous print protective layer, easily causes and protects unsuccessfully.It addition, solvent-based material is producing and in work progress, it is required to a large amount of Using the organic solvent such as toluene, butanone, these poisonous organic solvents evaporate in the environment that solvent-based material produces, and cause Working environment is severe, damages workers ' health, causes air environmental pollution, do not meet environmental requirement.
Summary of the invention
It is an object of the invention to provide a kind of water-repellent preservation water-repellent paint for concrete structures, to solve above-mentioned background The problem proposed in technology.
For achieving the above object, the present invention provides following technical scheme:

As the further scheme of the present invention: described aqueous corrosion-resisting resin uses water-borne acrylic resin.
As the present invention further scheme: described firming agent is made up of G class g cement and Gypsum Fibrosum.
As the present invention further scheme: described inorganic anti-corrosion filler is by metakaolin, sierozem power, glass flake and two Silicon oxide forms.
As the present invention further scheme: described auxiliary agent by alcohol ester 12, ethylene glycol, DOP, water, levelling agent, disappear Infusion, anti-heavy agent, reinforcing fiber and thickening agent composition.
As the present invention further scheme: described reinforcing fiber is the one in polypropylene fibre, polyethylene fibre or two Plant and combine.
As the present invention further scheme: described thickening agent is in hydroxypropyl methyl cellulose, hydroxyethyl cellulose Kind or two kinds combine.
As the present invention further scheme: described water-borne acrylic resin replaces with tertiary ethylene carbonate, poly-trifluoro chloroethene One or both combination in olefine resin.
As the present invention further scheme: described sierozem power replaces with dicalcium powder.
As the present invention further scheme: described metakaolin and silicon dioxide replace with silicon ash.
Compared with prior art, the invention has the beneficial effects as follows:
1, the coating of the present invention is water paint, is flexible material after coating film forming, and brushing can be oozed on concrete structures More than 0.2-0.3mm thoroughly, has well reparation and resistant function to the microcrack of concrete.
