Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of high ferro antibacterial polyurethane water-repellent paint.
Background technology
High ferro, fast ferrum (speed rail), general ferrum (general speed train, low speed railway) are the big class of Chinese Railway three.Speed per hour 160
Kilometer is above-and the most simply speed rail (being second to high ferro is " Asia high ferro ") of speed per hour less than 250 kilometers is quickly compared to speed per hour
The low speed railway of less than 160 kilometers i.e. usual speed railway." the railroad safety management bar of enforcement plays on January 1st, 2014 in China
Example " regulation: high-speed railway (high ferro) refers to that (containing reserved) is started speed per hour more than 250 kilometers in design, and initial stage operation speed per hour 200
The passenger train special line railway that kilometer is above.High-speed railway except at train in addition to operation reaches speed certain standard, vehicle, road
Rail, operation are required for coordinating and promote.
Waterproof material has the advantages that low temperature flexibility, self-healing property and adhesive property are good, can room temperature construction, speed of application fast and
Meet environmental requirement.Especially without Hot-melt construction, remove the melancholy of fire from.Waterproof material resistance to low temperature is good, it is adaptable to work
Industry is waterproof, moistureproof with the roofing of civil building, basement, indoor, municipal works, cistern, swimming pool, subway and tunnel
And sealing.It is particularly suited for needing the military installations of cold construction and the oil depot of naked light, chemical plant, textile mills, grain should not being employed
The water-tight corrosion-proof engineerings such as storehouse.
In the construction of high-speed railway, bridge floor arranges waterproof layer, is acknowledged as the most in the world, be can
Improve the maximally effective measure of bridge durability.The waterproof layer of bridge floor is easy to be destroyed.The waterproof layer of bridge floor is most commonly seen
Defect be exactly waterproof layer local breaking point occurs.The bridge surface waterproof layer of high-speed railway suffer local destruction after, if anti-
The bonding attachment of water layer and bridge deck concrete is unable to bear again the long-term infiltration of water and obscission occurs, such face meeting that comes off
Prolongation over time constantly expands, and then area hollowing occurs, also will appear from seeping phenomenon below waterproof layer, in driving
In the case of dynamic load, hydrops will produce corresponding pulse hydraulic pressure, and such reciprocating pressure time length will cause
The face that comes off of waterproof layer expands further, and concrete also has the destruction of corrosion.
