Description
Technical field
The present invention relates to a kind of waterproof paint, be specifically related to a kind of building with brick-concrete structure water-resisting agent.
Background technology
Until before the several years, people still think to have resistance to fouling by building with brick-concrete structure.But, along with building with brick-concrete structure is destroyed the continuous generation of event, people are recognized gradually: although building with brick-concrete structure intensity is very high, but still to be subject to destruction.Multiple negative impact, as rodent environmental activity (humidity of particularly constantly change), can accelerate the decline of brick mix structure performance, wherein particularly evident to the destruction of brick.
Freshly prepd masonry, because of the Ca(OH that hydrated cementitious produces) 2, KOH, NaOH and cause its alkalescence higher (pH=12 ~ 13), and masonry is not corroded.But through after a period of time, due to the effect by acidic gas in air CO2, SO2, NOx and moisture, wherein most importantly acting as carbonization process, i.e. Ca(OH) 2+H2O+CO2 → CaCO3 ↓+2H2O makes the pH value of masonry decline gradually.When pH value be down to be less than 9 time, masonry will lose erosion resistance, makes it be corroded.
Masonry is the material of a kind of heterogeneous body vesicular structure and hypertonicity, is the major cause affecting building with brick-concrete structure 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 of masonry, destruction is stronger, causes catastrophic corrosion.
Waterproof coating processing must be carried out to building with brick-concrete structure, its objective is:
(1) increase the resistance to CO2 penetrating power of masonry, namely increase resisting carbonization;
(2) increase the resistance to muriate penetrating power of masonry, reduce masonry to the adsorptive power of the nuisance be dissolved in the water;
(3) resistivity of masonry to frost and deicer salts is improved;
(4) improve brick masonry surface hydrophobic nature, reduce capillary suction, do not affect the water vapour permeability of masonry, even if masonry also can not reduce Corrosion Protection after soaking in basic solution;
(5) outward appearance of masonry is not affected.
And existing water-resisting agent on market, the demand of client can't be met in perviousness, water-absorbent and production cost etc., be thus necessary to develop a kind of novel building with brick-concrete structure water-resisting agent.
Summary of the invention
