Description
Technical field
The present invention relates to one kind the present invention relates to a kind of building coating, and in particular to a kind of organosilicon concrete protection emulsion
And preparation method thereof.
Background technology
With the increasingly extension of concrete structure range of application, its endurance issues in the presence of a harsh environment also gradually causes
The attention of people.In China's cold district, winter sleety weather is more, in order to ensure the unimpeded of highway, often in bridge and tunnel
A large amount of deicer salts are put on road, makes this area's concrete structure be subject to salt corrosion, particularly chlorion a large amount of using deicer salts
Penetrate into so as to change cement concrete interior tissue and structure, the use of concrete has been had a strong impact under Frozen-thawed cycled effect
Performance and endurance quality, make concrete construction sealer peeling and peeling in large area, and internal reinforcing bar is exposed and accelerates
Corrosion.It is the effective means for preventing deicing salting liquid from permeating in concrete surface applying protective coating, frequently with ring in engineering
The materials such as oxygen tree fat, polyurethane resin, fluorocarbon resin are formed with certain thickness fine and close flexibility in concrete structural surface
Diaphragm, prevents the infiltration of harmful solution.Degree of drying requirement of the type coating to inside concrete before construction is very high, because
While preventing the aqueous solution from entering concrete, the moisture of inside concrete cannot also be excluded for it, coating is played drum, or even
The freezing up layer on surface is formed in parallel with concrete superficial, causes the breakage of concrete structure.
The emulsion particle diameter of organosilicon concrete protection emulsion is less than 0.15 μm, and outward appearance is translucent to transparent, between emulsion
A kind of state between solution, can make up the not enough defect of stability of organic silicone emulsion, with good storage stability and
Excellent permeability.Organosilicon material forms the permeable formation of certain depth by the pore of concrete surface, is mixed in permeable formation
The polycondensation of solidifying soil capillary hole surface organosilicon forms hydrophobic film, concrete surface is had the performance of permeable watertight, is mixed
The ideal material of solidifying soil surfacecti proteon.
