Abstract
The invention discloses an anticorrosive steel concrete sleeper. The surface of a steel concrete sleeper is uniformly provided with an anticorrosive layer, and the anticorrosive layer is solidified epoxy resin mortar. The invention also discloses a production method of the anticorrosive steel concrete sleeper. The method comprises the following steps: making a steel concrete sleeper with a traditional form according to national Quality Standards and Requirements of Concrete Sleeper, wherein the external surface dimension of the steel concrete sleeper inwardly contracts for 1mm; mixing all component materials of the anticorrosive layer according to a certain weight ratio to prepare the epoxy resin mortar; and uniformly spraying the epoxy resin mortar on the surface of the sleeper to make the thickness of the surface layer be 1-1.2mm, and solidifying the mortar for 12h. An organic composite material with high compactness and high strength is compounded to the surface of the traditional steel concrete sleeper in order to prevent the surface of the sleeper from being corroded by all etching media, so the service life of the sleeper is prolonged, the replacement period of the sleeper is prolonged, and the maintenance cost of the sleeper is effectively reduced.
Description
Technical field
The present invention relates to technical field of rail traffic, to one layer of anti-corrosion material of sleeper surface recombination, solve tradition
Reinforced concrete sleeper causes the problem that sleeper destroys, specifically anticorrosion one reinforcing bar to be mixed because of surface corrosion
Solidifying soil sleeper and preparation method thereof.
Background technology
At present, the track traffic sleeper major part of China is all reinforced concrete sleeper.The structure of concrete is special
Property is the structural material of a kind of non-homogeneity, and from microstructure, it is belonging to porous body, has perhaps inside it
The fine pore varied in size, the medium of all erosions can be corroded by these holes and crack more
Concrete.It is as the main material of reinforced concrete sleeper, when sleeper surface exposure holds in adverse circumstances
Easily by aqueous corrosion, acid corrosion, caustic corrosion, and then further infiltration of cracking makes inside it under dynamic load effect
Reinforcement corrosion, causes sleeper to destroy.
Summary of the invention
According to technical problem set forth above, and provide a kind of anticorrosive steel reinforced concrete sleeper and preparation method thereof.
The present invention uses a kind of organic composite material with higher densification and intensity, is compound to tradition reinforcing bar
Concrete sleeper surface, makes sleeper surface from the corrosion of all erosion media, increases the use longevity of sleeper
Life, extends the cycle changing sleeper, effectively reduces the maintenance cost of sleeper.
The technological means that the present invention uses is as follows:
A kind of anticorrosive steel reinforced concrete sleeper, it is characterised in that: described reinforced concrete sleeper surface is uniform
Arranging one layer of anticorrosive coat, described anticorrosive coat is the epoxy resin mortar after solidification.
Further, described epoxy resin mortar includes each component that weight proportion is following:
Described cementing agent is epoxy resin, and described firming agent is ethylenediamine, and described toughener is phthalic acid
Dibutyl ester, described diluent is acetone, and described aggregate is the fine sand that particle diameter is less than 0.5mm.
Further, described reinforced concrete sleeper be according to country " quality standard of concrete sleeper and want
Ask " manufacture, its exterior surface dimension is to inside contracting 1mm.
Further, the thickness of described anticorrosive coat is 1mm-1.2mm.
The invention also discloses the preparation method of a kind of above-mentioned anticorrosive steel reinforced concrete sleeper, it is characterised in that:
Comprise the steps:
S1, according to country " quality standard of concrete sleeper and requirement " manufacture traditional form reinforced concrete
Soil sleeper, its exterior surface dimension is to inside contracting 1mm；After treating the above-mentioned sleeper timeliness phase, its removing surface is done
After clean, neat spaced horizontal is put；
S2, it is configured to epoxy resin mortar by preparing after each component material of anticorrosive coat mixes according to weight proportion；
S3, by epoxy resin mortar even application to sleeper surface, skin depth is 1mm-1.2mm, solidification
Timeliness 12 hours.
Further, described epoxy resin mortar is at 20 ± 1 DEG C, first puts preset weight in blender
Epoxy resin, is subsequently adding diluent and the toughener of default proportioning, adds fine sand and the fine coal presetting proportioning
Ash, the uniform 3-4min of stirring at low speed；The ethylenediamine adding preset ratio is sufficiently stirred for 4-6min, finally joins
The epoxy resin mortar made is finished in 50min.
Further, described fine sand and described flyash are drying regime, and described fine sand particle diameter is less than 0.5mm.
The present invention uses epoxy resin, to contain in its molecule as a kind of Organic substance as cementing agent, epoxy resin
There are a large amount of polar hydroxyl groups and ehter bond, various materials all had the highest cohesive force, reacts with firming agent,
Producing hydrogen bond association, its cure shrinkage is the lowest, has the strongest cohesiveness, the asphalt mixtures modified by epoxy resin after solidification
Fat main chain is ehter bond and phenyl ring, three-dimensional cross-linked structure densification are closed again, therefore has the alkali resistance of excellence, resistance to
Acidity and solvent resistance.In epoxy resin mortar, epoxy resin as cementing agent and firming agent, toughener,
After diluent generation chemical reaction by bonding to aggregate and flyash become mortar by spraying be compound to tradition reinforcing bar mix
Solidifying soil sleeper surface, constitutes effective anticorrosive coat, makes sleeper surface from the corrosion of all erosion media.
Raw steel reinforced concrete rail compared by the reinforced concrete sleeper after composite epoxy resin screed of the present invention
Pillow has the following advantages: sleeper surface strength hardness significantly improves and not cracky；Water can not be from surface penetration rail
Pillow is internal；The soda acid of general concentration cannot permeating corrosion sleeper；Reinforcing bar within sleeper is the most perishable；Sleeper
Face crack significantly reduces.
Present invention can apply to all humidities and acid-base value content suffers more greatly and easily the steel that corrosive environment uses
Manufacturing and designing of reinforced concrete sleeper, such as: the interior railroad sleeper of extractive industry mine, annual rainfall are significantly
District's railroad sleeper, acid-base value larger area, northwest railroad sleeper etc..
