Description
Technical field
The present invention relates to field of polymer composite material, and in particular to a kind of fiber reinforcement composite sleeper and its preparation side
Method.
Background technique
The sleeper that rail track uses at present is mainly prestressed reinforced concrete sleeper and sleeper.Well known prestress steel
Reinforced concrete sleeper is easy to guarantee manufactured size due to its abundant raw material, and quality is big, the service life is long, and can improve the stabilization of track
Property, therefore be widely used in railroad track.But prestressed reinforced concrete sleeper is since single weight is big, it is existing
It is difficult to install, while there is also the drawbacks such as poor flexibility, rigidity is big, are limited in specific region or position use.It is known
Sleeper due to it have many advantages, such as elasticity is good, it is easy to process, be convenient for changing, obtained extensively in Special zones such as bridge, track switches
It uses.But it makes sleeper and needs good hard wood, high-quality timber resources is limited, this is unfavorable for the sustainable of ecological environment
Property.Simultaneously in order to which the corrosion resistance of sleeper prolongs the service life, chemical preservative is used in sleeper manufacturing process, this also can
Hidden danger is brought to the health of environment and worker.
For defect possessed by current common prestressed reinforced concrete sleeper and sleeper and composite technology
It continues to develop.The composite material of long fiber reinforcement foamed resin material is a kind of substitution material well.Long glass fibres enhancing
Foamex has structure similar with natural timber, can be used as rail traffic facility, building decoration materials replace timber.
Since the continuous fiber reinforced composite materials drawing and extruding section bar with excellent properties substitutes traditional timber, steel, coagulation
Soil etc. is widely used in the industries bearing structure such as building, bridge, electric power, energy field.Therefore, the demand of pultrusion composite materials
It quicklys increase, along with the continuous improvement to performance requirement, structural member size constantly increases, and the big big thickness pultrusion in section is multiple
Condensation material comes into being.
Resin liquid is main to the process of the dipping of continuous fiber in continuous fiber reinforced composite materials drawing and extruding section bar at present
Using steeping vat and injecting glue box device.Since impregnation slot device generally uses opened type, resin liquid is readily volatilized, to production ring
Border and workers ' health cause security risk；And opened type steeping vat is suitable for one pack system or ambient temperature curing slower system,
Such as phenolic resin, vinylite.If in injecting glue box device in use, resin liquid can be made directly to be soaked by glue-injection machine
Enter in closed glue-injection box and be not directly exposed in air, then can obviously improve production environment.In addition, injecting glue used at present
The profile thickness that box dipping obtains is relatively thin, and the thickness of glue-injection box is usually no more than 5mm.Therefore big section large scale is limited
The preparation of pultrusion composite materials.
Summary of the invention
To overcome defect and deficiency existing in the prior art, the invention discloses a kind of fiber reinforcement composite sleepers.
The invention is realized by the following technical scheme:
A kind of preparation method of fiber reinforcement composite sleeper, comprising the following steps:
Reinforcing fiber materials are imported glue-injection box by S1. guide；
S2. it impregnates, Foamex matrix is injected in Xiang Suoshu glue-injection box, so that the reinforcing fiber materials are in the foaming
It is impregnated in resin matrix；
S3. it post-processes, the Foamex matrix that the reinforcing fiber materials are distributed with to internal and/or surface carries out
It squeezes, molding, cooling and cutting, obtains the fiber reinforcement composite sleeper；
The glue-injection box is the hollow box of sealing, and the glue-injection box is equipped with hole for injecting glue, the both ends point of the glue-injection box
Not She You entrance and exit, the Foamex matrix passes through the hole for injecting glue and injects the glue-injection box, the reinforcing fiber material
Material enters the glue-injection box by the entrance, and is impregnated in the Foamex matrix, the distribution of internal and/or surface
There is the Foamex matrix of the reinforcing fiber materials to send out by the outlet.
Further, the glue-injection box includes cope plate and lower template, the hole for injecting glue be set to the cope plate and/or
In lower template, the cope plate and lower template surround jointly and form closed injecting glue cavity；The entrance and exit respectively with institute
State the connection of injecting glue cavity.
Further, the cope plate is open equipped with cope plate；The lower template is open equipped with lower template；The cope plate
The position of opening and lower template opening corresponds to each other, and the entrance is collectively formed.
Further, the cope plate and/or lower template are equipped with several fastening bolt holes and fastening bolt.
Further, the glue-injection box further includes several intermediate die plate, and the intermediate die plate is set to the upper mold
Between plate and lower template, the injecting glue cavity is divided into several the sub- cavity of injecting glue.
Further, the upper and lower ends of the intermediate die plate are respectively equipped under intermediate die plate upper opening and intermediate die plate and open
Mouthful.
Further, the preparation method of the fiber reinforcement composite sleeper, further comprising the steps of:
S4. quantity is mutually bonded to be more than two by the fiber reinforcement composite sleeper that step S3 is obtained.
Further, in step s 4, the different more than two fiber reinforcement composite sleepers of density are mutually viscous
It connects.
Further, the reinforcing fiber materials are at least one of continuous reinforcing fiber and/or fabric.
A kind of fiber reinforcement composite sleeper that the preparation method using the fiber reinforcement composite sleeper obtains.
Compared with prior art, the present invention the advantage is that: the present invention by injecting glue solve production composite sleeper when it is big
The insufficient problem of dipping of silvalin beam is measured, and by the glue-injection box of setting sealing, is directly immersed in resin liquid by glue-injection machine
