Description
Technical field
The present invention relates to technical field of rail traffic, gives sleeper surface recombination one layer of anti-corrosion material, solves traditional reinforcing bar and mix
Coagulate native sleeper because surface corrosion cause sleeper to destroy the problem of, specifically a kind of reinforced concrete sleeper of anti-corrosion and its preparation
Method.
Background technology
At present, it is all reinforced concrete sleeper that the track traffic sleeper in China is most of.The architectural characteristic of concrete is one
The structural material of kind of non-homogeneity, it is to belong to porous body from microstructure, is had inside it many of different sizes fine
Hole, the medium of all erosions can carry out corrosion concrete by these holes and crack.It is as armored concrete rail
The main material of pillow, when sleeper surface exposure in adverse circumstances easily by aqueous corrosion, acid corrosion, caustic corrosion, and then in dynamic load
The lower cracking of lotus effect, which is further permeated inside it, makes reinforcement corrosion, causes sleeper to destroy.
The content of the invention
According to technical problem set forth above, and provide a kind of anti-corrosion reinforced concrete sleeper and preparation method thereof.This hair
It is bright using a kind of organic composite material with higher densification and intensity, be combined to conventional steel bar concrete sleeper table
Face, make sleeper surface from the corrosion of all erosion media, increase the service life of sleeper, extend the cycle for changing sleeper,
Effectively reduce the maintenance cost of sleeper.
The technological means that the present invention uses is as follows：
A kind of anti-corrosion reinforced concrete sleeper, it is characterised in that：The reinforced concrete sleeper surface uniformly sets one
Layer anticorrosive coat, the anticorrosive coat are the epoxy resin mortar after solidification.
Further, the epoxy resin mortar includes the following each component of weight proportion：
The cementing agent is epoxy resin, and the curing agent is ethylenediamine, and the toughener is dibutyl phthalate,
The diluent is acetone, and the aggregate is the fine sand that particle diameter is less than 0.5mm.
Further, the reinforced concrete sleeper is according to country《The quality standard of concrete sleeper and requirement》Manufacture
, its exterior surface dimension is to inside contracting 1mm.
Further, the thickness of the anticorrosive coat is 1mm-1.2mm.
The invention also discloses a kind of preparation method of above-mentioned anti-corrosion reinforced concrete sleeper, it is characterised in that：Including
Following steps：
S1, according to country《The quality standard of concrete sleeper and requirement》The reinforced concrete sleeper of traditional form is manufactured,
Its exterior surface dimension is to inside contracting 1mm；After treating the above-mentioned sleeper timeliness phase, by the clean rear neat spaced horizontal pendulum of its removing surface
Put；
S2, it is configured to epoxy resin mortar after each component material for preparing anticorrosive coat is mixed according to weight proportion；
S3, by epoxy resin mortar even application to sleeper surface, skin depth 1mm-1.2mm, solidification timeliness 12 is small
When.
Further, the epoxy resin mortar is the asphalt mixtures modified by epoxy resin for first putting preset weight in mixer at 20 ± 1 DEG C
Fat, the diluent and toughener of default proportioning are then added, add the fine sand and flyash of default proportioning, the uniform 3- of stirring at low speed
4min；The ethylenediamine for adding preset ratio is sufficiently stirred 4-6min, and the epoxy resin mortar finally prepared is used in 50min
It is complete.
Further, the fine sand and the flyash are drying regime, and the fine sand particle diameter is less than 0.5mm.
The present invention is used as cementing agent using epoxy resin, and epoxy resin is as a kind of organic matter, containing largely in its molecule
Polar hydroxyl groups and ehter bond, there is very high cohesive force to various materials, reacted with curing agent, produce hydrogen bond association,
Its cure shrinkage is very low, has very strong cohesive force, and the epoxy main chains after solidification are ehter bond and phenyl ring, three-dimensional crosslinking knot
Structure is fine and close to be closed again, therefore has excellent alkali resistance, acid resistance and solvent resistance.In epoxy resin mortar, epoxy resin is made
Pass through spraying into mortar by aggregate and flyash are Nian Jie after being chemically reacted for cementing agent with curing agent, toughener, diluent
Conventional steel bar concrete sleeper surface is combined to, forms effective anticorrosive coat, makes sleeper surface from the corruption of all erosion media
Erosion.
The reinforced concrete sleeper after composite epoxy resin screed of the present invention has compared to raw steel reinforced concrete sleeper
Following advantage：Sleeper surface strength hardness is significantly improved without cracky；Water can not be inside surface penetration sleeper；General concentration
Soda acid can not permeating corrosion sleeper；Reinforcing bar inside sleeper is not perishable；Sleeper face crack significantly reduces.
Present invention can apply to all moist and acid-base value contents, reinforcing bar that is larger and easily being used by corrosive environment mixes
The design and manufacture of native sleeper are coagulated, such as：The interior railroad sleeper of extractive industry mine, annual rainfall larger area railroad sleeper, northwest
Acid-base value larger area railroad sleeper etc..
Embodiment
The present invention is combined to traditional reinforcing bar and mixed using a kind of organic composite material with higher densification and intensity
Native sleeper surface is coagulated, makes sleeper surface from the corrosion of all erosion media, the service life of sleeper can be increased, extend and change
