Description
Technical field
The present invention relates to a kind of waterproof paint, be specifically related to a kind of steel reinforced concrete structure building water-resisting agent.
Background technology
Concrete steel building is the material of a kind of heterogeneous body vesicular structure and hypertonicity, is the major cause affecting concrete steel building weather resistance.It is by capillary attraction water, and its process is usually along with the absorption to objectionable impurities.With regard to water self, water can make salinity by the internal migration of material to outside, thus make building surface weathering and salt efflorescence, water can cause material generation frost and thaw, if the long-term erosion by moisture in air, will make that wall is done, wet alternate heavily stressed, cause surface cracking, water can make wall mouldy and corrosion reinforcing bar.In addition, water can also carry pollutent and dust secretly, makes buildings stained.And the material be dissolved in the water, particularly chlorion, because destroying the passivation layer on reinforcing steel bar surface, destruction is stronger, causes catastrophic corrosion.
Waterproof coating processing must be carried out to concrete steel building, its objective is:
(1) increase the resistance to CO2 penetrating power of Steel Concrete, namely increase resisting carbonization;
(2) increase the resistance to muriate penetrating power of Steel Concrete, reduce Steel Concrete to the adsorptive power of the nuisance be dissolved in the water;
(3) resistivity of Steel Concrete to frost and deicer salts is improved;
(4) improve reinforced concrete surface hydrophobic nature, reduce capillary suction, do not affect the water vapour permeability of Steel Concrete, even if Steel Concrete also can not reduce Corrosion Protection after soaking in basic solution;
(5) outward appearance of Steel Concrete is not affected.
