Abstract
The present invention relates to antiseptic concrete technical field, it is desirable to provide a kind of application method of maritime concrete protection land used polymer coating materials.This method is that geopolymer coating material is coated in into maritime concrete surface, 5~10mm of coating layer thickness by the way of spraying or brushing；Coating flawless after coating, adhesive force >=2.0MPa, protected maritime concrete 6h electric fluxes≤500C.The present invention uses multi-ensuring measure, collaboration enhancing polymer coating materials anti-dry-shrinkage cracking property；Organic functional material is compounded, strengthens the hydrophobic and anti-ion infiltration function of geopolymer coating material；By preferred function auxiliary agent, geopolymer coating material rheological property is improved, eliminates in preparation process bubble in slurry, enhances the workability of geopolymer coating material.
Description
Technical field
The present invention relates to Marine Engineering High-performance Concrete technical field of anticorrosion, and in particular to a kind of maritime concrete protects land used
The application method of polymer coating materials.
Background technology
China is ocean big country, develops marine resources, Development of Marine economy is China's grand strategy decision-making.Ocean engineering is built
If it is the important prerequisite and basic guarantee of comprehensive marine exploitation, but (radiation is strong, salinity is high, wet due to the particularity of marine environment
Degree is big etc.), metal material corrosion and destruction, the expansion of reinforced concrete structure cracking, high polymer material deformation deterioration etc. can be caused existing
As.Concrete has high requirements as ocean engineering important materials to its durability.Conventional Marine Engineering High-performance Concrete is to suppression
The deterioration of material has certain effect with failure under marine environmental conditions processed, but it can not fundamentally solve villaumite under marine environment
With corrosion of the sulfate to concrete material.Its basic reason after being ordinary cement aquation is formed with C-S-H gels and 3Ca
(OH)2Based on heterogeneous material, SO4 2-、Cl-、Mg2+Plasma is easily with the calcium hydroxide in water mudrock structure, aluminium sulfate etc.
Crystalline phase reacts, and causes volume of concrete change, short texture, shortens ocean engineering active time, cause serious commercial
Loss and life and property loss.
Geopolymer (Geopolymer) end of the seventies in last century proposes by professor Davidovits, also known as inorganic polymeric
Thing, it is that alkali-activator reacts a kind of using aluminum-oxygen tetrahedron and silicon-oxy tetrahedron as structural units of generation with aluminosilicate material,
Three-dimensional network shape gel with crystalline state and amorphous state feature.Geopolymer raw material sources are extensive, and preparation technology is simple, have
Ceramics and organic matter feature performance benefit, are a kind of novel gelled materials, are expected to substitute conventional cement binder materials.Geopolymer permeates
Rate is low, high with concrete adhesive force, without crystalline phases such as calcium hydroxide, aluminium sulfates, not with SO in ocean4 2-、Cl-、Mg2+Deng
Ion etc. reacts, and corrosion resistance is strong, firm in structure, one of preferred material that can be as ocean engineering material.Li Wenjin is (inorganic poly-
Compound durability of marine concrete is studied, Harbin Institute of Technology's Master's thesis, 2012) using slag as aluminosilicate material,

Comparative example 22
By " coating layer thickness 8mm " is replaced by that " coating layer thickness 12mm ", remaining is equal to embodiment 5, coating in embodiment 5
3 can be shown in Table.
Comparative example 23
" natural sand (particle diameter≤2.36mm, clay content are less than 0.5%) 120 parts " in embodiment 5 is replaced by " natural sand
(particle diameter≤2.36mm, clay content are less than 0.5%) 40 parts ", remaining is equal to embodiment 5, and coating performance is shown in Table 3.
Comparative example 24
" natural sand (particle diameter≤2.36mm, clay content are less than 0.5%) 120 parts " in embodiment 5 is replaced by " natural sand
(particle diameter≤2.36mm, clay content are less than 0.5%) 220 parts ", remaining is equal to embodiment 5, and coating performance is shown in Table 3.
The geopolymer protective coating performance of table 4.
It can be seen that from comparative example 1-24 data：
(1) asphalt emulsion, PP fibers, the collaboration of MgO bases swelling agent are used, and geopolymer coating can be overcome to dry and shrink generation
Crack, it is avoided that Cl-Penetrate to maritime concrete surface, reduce maritime concrete electric flux value, improve antiseptic property；
(2) use of the organic functional material such as asphalt emulsion, isobutyl triethoxy silane, can improve geopolymer coating
Material hydrophobic function, Cl can be prevented-Maritime concrete surface is infiltrated into, maritime concrete electric flux value is also reduced, improves
Antiseptic property.
(3) parameter such as geopolymer coating material formulation scope and coating layer thickness all has strict demand, such as increase drip
Blue or green emulsion dosage can cause coating adhesion to decline, and reduce asphalt emulsion dosage, and coating electric flux can be caused to raise, and increase applies
It can cause coating cracking after layer, and reduce coating layer thickness, then antiseptic property declines, and electric flux also raises.
Finally, it is also necessary to it is noted that listed above is only several specific embodiments of the invention.Obviously, this hair
It is bright to be not limited to above example, there can also be many deformations.One of ordinary skill in the art can be from present disclosure
All deformations for directly exporting or associating, are considered as protection scope of the present invention.
