Abstract
The invention relates to a vibration damping composite rubber mat plate used under a railway rail and a preparation method thereof. The rubber mat plate comprises a stainless steel plate (1) and a rubber plate (2), wherein, the stainless steel plate (1) is stuck on the upper surface of the rubber plate (2); the rubber mat plate is characterized in that the lower surface of the stainless steel plate (1) is welded with a metal screen plate (3), and the stainless steel plate (1) and the metal screen plate (3) are connected on the upper surface of the rubber plate (2). The stainless steel plate of the composite rubber mat plate is stuck and integrated with the rubber plate by the metal screen plate, so that the aesthetic property of the stainless steel surface is ensured, and the adhesive attraction between the stainless steel plate and the rubber can be greatly improved; therefore, the stainless steel plate and the rubber are well stuck with each other and not easy to deglue, the service life is prolonged, and the preparation process is simpler. The rubber mat plate can be used for buffering the high speed vibration and impact extrusion force which are generated when vehicles pass through the steel rail, thus protecting a roadbed and a rail bearing of the steel rail and making electric insulation for a signal system.
Description
Technical field
The present invention relates to a kind of rubber tile, particularly a kind of composite rubber plate and preparation method thereof that is applied under the railway rail.
Background technology
Present railway rail structure for cushioning between rail and sleeper the composite rubber mat plate that is compounded to form with stainless steel substrates and General Purpose Rubber backing plate, the vibration when driving a vehicle between rail and the sleeper with minimizing.When the new round of Nanjing Yangtze River Bridge railway access bridge in 1998 switches tracks overhaul, just changed former sleeper, laid concrete sleeper and gapless track, by institute of iron section design, between rail and sleeper cushioning composite rubber mat plate.But along with the speed raising of railway, bridge foundation vibrates increase in running at high speed.Rail displacement when high speed traveling increases, cause the resistance of rail and backing plate to increase, the situation that the stainless steel substrates that composite rubber mat plate will take place this rubber mat plate is in use for some time extruded under the rail, thereby cause the track imbalance, reduce the quality of railway track, influenced traffic safety.In order to solve this difficult problem, the technician has changed partly new composite rubber mat plate or has reinforced with screw, but can't fundamentally solve the problem that compound backing plate comes unstuck, stainless steel substrates is extruded.
Stainless steel surfaces does not pass through specially treated in the composite rubber mat plate that uses at present, the bonding relatively difficulty of stainless steel and rubber, the general bond strength that adopts ways such as sandblast in the surface, hacking to improve metal and rubber, but because the particularity of compound backing plate environment for use adopts old way can not satisfy instructions for use simply.And existing compound backing plate corrosion resistant plate is bonding with rubber employing cold-adhered mode, promptly adopt 801 bonding adhesive or other similar bonding adhesive, behind the common backing plate surface and stainless steel surfaces simple process that have vulcanizated, each is brushed one time or twice adhesive, and the adhesive bond of colding pressing forms.Corrosion resistant plate that this kind production technology is produced and rubber do not form one, are applicable in the non-dynamic environment, then because of its bonding force deficiency, very easily cause degumming phenomenon in the dynamic environment.
Summary of the invention
Purpose of the present invention then is bad at adhesion stress between the corrosion resistant plate of using vibration damping composite rubber mat plate under the at present existing rail and the rubber tile, caducous shortcoming, provide a kind of corrosion resistant plate and rubber tile bonding force good, difficult disengaging, vibration damping composite rubber mat plate used under railway rail that damping property is good and preparation method thereof.
Purpose of the present invention can realize by following measure:
Vibration damping composite rubber plate under a kind of railway rail, include corrosion resistant plate and rubber tile, corrosion resistant plate is bonded in the rubber tile upper surface, it is characterized in that the soffit of described corrosion resistant plate is welded with metal otter board, and corrosion resistant plate and net-shaped metal plate are connected to the rubber mat plate upper surface jointly.
Described rubber mat plate side is provided with the through hole of a plurality of phase line parallels.
A kind of method for preparing vibration damping composite rubber plate under the railway rail, its technology step is poly-as follows:
(a) corrosion resistant plate sanction and net-shaped metal plate are cut into laggard andante face of suitable shape and the welding of plate face;
(b) natural rubber and synthetic rubber are plasticated with mixing;
(c) with the one side of above-mentioned rubber-moulding after mixing, form rubber mat plate to corrosion resistant plate welding net-shaped metal plate;
(d) rubber mat plate that advances above-mentioned formation carries out the integral body sulfuration, obtains vibration damping composite rubber mat plate.
Described corrosion resistant plate thickness is 1-1.2mm, and by the sandblast hacking, the welding manner of it and net-shaped metal plate is spot welding before preceding welding.
Corrosion resistant plate after the welding and net-shaped metal plate carry out after surface acid-washing, washing, oven dry, coating adhesive, the oven dry and rubber-moulding again.
Conditions of vulcanization was 155 ℃ of curing temperatures during described (d) step was poly-, sulfide stress 0.8MPa, cure time 15min.
Corrosion resistant plate in the composite rubber mat plate provided by the invention is bonded into one by net-shaped metal plate and rubber tile; both solved the aesthetic property of stainless steel surfaces; the adhesive power of corrosion resistant plate and rubber is greatly improved; make the bonding between them fine, be difficult for coming unstuck, prolong application life; preparation is also fairly simple simultaneously; it can cushion vehicle by vibration at high speed and impact extruded power that rail produced, protects rail roadbed and sleeper, and signal system is carried out electric insulation.
Description of drawings
Fig. 1 is the structural representation of rubber mat plate of the present invention.
Fig. 2 is the process chart of composite rubber mat plate of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
As shown in Figure 1, the present invention has welded net-shaped metal plate 3 in the bottom surface of corrosion resistant plate 1, makes corrosion resistant plate 1 and rubber tile 2 moulding again, makes corrosion resistant plate 1 and net-shaped metal plate 3 be connected to rubber tile 2 upper surfaces jointly, forms rubber mat plate.The mesh that rubber tile 2 upper surfaces after the moulding see through net-shaped metal plate 3 can bond to corrosion resistant plate 1 bottom surface, thereby the corrosion resistant plate 1 and the bond strength of rubber tile 2 are greatly improved, and can't peel off by hand.When doing disbonded test, draw corrosion resistant plate 1 and rubber tile 2 respectively from the rubber mat plate both sides with external force, rubber mat plate is broken, and corrosion resistant plate 1 does not separate yet with rubber tile 2.In order to strengthen the damping property of rubber mat plate, be provided with a plurality of through holes 4 that are level in the side of rubber tile 2, each through hole 4 is parallel to each other, and is positioned at the top of leaning on of rubber tile 2, promptly near corrosion resistant plate 1.Through hole 4 can make corrosion resistant plate 3 better with the elasticity of rubber tile 2 vertical direction, and rubber mat plate is stronger to the extruding ability to bear of rail when making driving.
As shown in Figure 2, preparation method's process is as follows particularly for rubber mat plate of the present invention:
