Description
Technical field
The present invention relates to technical field of coatings more particularly to a kind of high ferro Special high-strength water-repellent paints.
Background technology
With the rapid development of high-speed railway cause and to high-speed railway high standards, bridge used for high-speed railway and overhead
Bridge is increasing.The structure type of the simply supported beam used in high-speed rail bridge using Urban Bridge, bridge is using reinforcing bar
Concrete material, therefore the hogging moment of the armored concrete in high-speed rail bridge and concrete bridge deck are in the reloading by train
Caused high speed vibration, tensile shear and enormous impact effect, and brought temperature by the climate change of external local environment
After convergent-divergent caused by humidity, bridge can generate some subtle cracks on coagulation, although and these cracks cannot be short
The bearing capacity of structure is reduced in phase, but certainly will be when raining or bridge floor there are a large amount of ponding after the use of regular period
Bridge floor is caused to occur seeping water or leak occurs when serious, leads to the corrosion of reinforcing bar, and water also can be with sclerotin active in concrete
It is opened with calcium substance generation colloid silico-calcium, this substance can make concrete expansion generate new crackle so as to affect high-speed railway
Permanent usability and safety.
The design of concrete-bridge waterproof is unreasonable, waterproof material is with low quality in construction and use in load mistake
Armored concrete will be caused to generate crack, and the various reactions of concrete-bridge itself are likely to that concrete-bridge is made to generate respectively
The crack of kind various kinds, such as alkali, unfreezing, drying shrinkage, sulfuric acid salt action.It to be split in use since there are these
Seam, rainwater or bridge floor ponding have readily been advanced in concrete, so as to aggravate the freeze thawing of concrete damage, are especially existed
Northern area, the salting snow melting method that winter is commonly used can enter brine ice leads to reinforcement corrosion in reinforcing bar, reduce steel
The loaded area of muscle is also equivalent to reduce the reinforcing bar utilization rate of bridge, finally damages bridge.
High-speed rail bridge Waterproofing Layer for Concrete Bridge Deck refers to thin layer of the making between railway track plate and bridge concrete, this
The main function of layer waterproof layer is for stop that rainwater lotus ponding point enters in the concrete of girder, preventing moisture corrosion steel
Muscle.Therefore visible waterproof material has the function of that being used as moisture is isolated in dual on the one hand play, on the other hand due to having
Viscosity itself can also form an entirety by itself adhesive property and bottom, and the ability of extraneous load and deformation is resisted in enhancing.
Invention content
For above-mentioned deficiency in the prior art, the first technical problem to be solved by the present invention is to provide a kind of high
Iron Special high-strength water-repellent paint.
