Abstract
The invention discloses a geopolymer-base sea-base concrete protective coating. Since a marine environmental area is relatively high in humidity and high in seepage pressure and contains a great amount of salt, reinforcing steel bars in concrete are likely to corrode, the concrete is likely to fracture and strip, and thus the service life of a coastal building is severely shortened. The geopolymer-base sea-base concrete protective coating is prepared from the following raw materials: dry powder water glass, slag, metakaolin, nano zinc oxide, nano titanium dioxide, a surfactant, a water-retaining agent, superfine wollastonite powder, superfine calcined kaolin, superfine aluminum oxide and ground limestone. On the basis of the geopolymer synthesis material technology, the advantages of the geopolymer such as high strength, excellent construction performance, chemical corrosion resistance, high temperature resistance and good durability are adequately utilized, a dry-mixed sea-base concrete protective coating which is high in corrosion resistance, good in durability and low in cost is prepared, and the protective coating can well fill clearances of concrete, can prevent the reinforcing steel bars in the concrete from being corroded, and is durable.
Description
Technical field
What the present invention relates to is a kind of ground polymers Ji Haiji concrete protection coating, belongs to new material technology field.
Background technology
Affect weather resistance, erosion resistance that this type of most critical factor of building work-ing life such as building, harbour, harbour that borders on the sea is concrete structure.But because ocean environment area humidity is bigger than normal, seepage water pressure is strong, and containing a large amount of salt, in its salt, etc. enter concrete pore interior, generates swelling property product with some component generation chemical reaction of Behavior of Hardened Cement Paste, concrete surface layer is ftractureed or softens.Crack has encouraged again the infiltration of chlorion, sulfate ion, accelerates concrete destruction further, makes concrete strength degradation, and weather resistance is lost.Therefore, sea base concrete is by the impact of this ocean environment, and reinforcement in concrete is easily corroded, and concrete very easily ftractures, peel off, and causes building life serious curtailment.In addition the factor affecting sea base concrete life also has concrete carbonization.Because concrete carbonization makes concrete pH value decline, cause steel bar corrosion, this will directly have influence on the weather resistance of skeleton construction.Therefore analyze from technical standpoint, research and develop a coating sea base concrete being played to lasting protective effect and the construction industries such as building, harbour, harbour that border on the sea are significant.
Summary of the invention
The object of this invention is to provide a kind of ground polymers Ji Haiji concrete protection coating; it is a kind of dry powder paint; this coating has that erosion resistance is strong, wear resistance is strong, good endurance, the advantage such as with low cost; overcome the problems such as current sea base concrete protection coating cost is high, military service process exists serious peeling phenomenon, difficult transport; and effectively slow down sea base concrete carbonization and reinforcing bar and to be corroded speed, improve the sea base concrete life-span.
Foregoing invention object is achieved through the following technical solutions: a kind of ground polymers Ji Haiji concrete protection coating, prepares: dry powder water glass 5-15 part, slag 15-25 part, metakaolin 20-40 part, nano zine oxide 1-5 part, nano titanium oxide 3-8 part, tensio-active agent 1-3 part, water-holding agent 0.5-2 part, ultra-fine wollastonite powder 3-8 part, ultra-fine calcined kaolin 5-15 part, ultra-fine aluminium sesquioxide 1-5 part, water-ground limestone 3-8 part primarily of following weight parts raw material.

Described nano zine oxide is commercially available zinc oxide white crystal;
Described nano titanium oxide is commercially available Rutile type Titanium Dioxide;
Described tensio-active agent is commercially available instant modified resin rubber powder;
Described water-holding agent is commercially available Natvosol;
Described ultra-fine wollastonite powder is that fineness is greater than 1000 object commercially available prod;
Described ultra-fine calcined kaolin is that fineness is greater than 4000 object commercially available prod;
Described ultra-fine aluminium sesquioxide is that fineness is greater than 4000 order commercially available prod;
Described water-ground limestone is that fineness is greater than 800 object commercially available prod.
The preparation method of above-mentioned a kind of ground polymers Ji Haiji concrete protection coating is: be packaged to be product after taking various raw material mixing and stirring according to aforementioned weight.Described ground polymers Ji Haiji concrete protection coating at a kind of dry powder paint, when using product in powder: water=1:0.5 ratio adds water and to stir use.
Take the present invention of above-mentioned measure; based on ground polymers synthetic materials technology; take full advantage of that geopolymer intensity is high, workability is excellent, resistance to chemical attack, the advantage such as high temperature resistant, good endurance; prepare that a kind of erosion resistance is strong, good endurance, with low cost be dry mixed sea base concrete protection coating; this protective coating can well fill concrete gap blocking, etc. enter concrete erosion reinforcing bar, and durable.Tool has the following advantages:
1, the present invention adopt main raw material be ground polymers, its abundance, cheap, erosion resistance and wear resistance strong.
2, product of the present invention is dry powder paint, convenient transportation, overcomes the difficult transportation problem of emulsion paint.
3, the present invention ground polymers Ji Haiji concrete protection coating is very easy to use, stirs and can use, can carry out spraying, brushing and roller application at concrete surface as long as add water in proportion when using.
