Vibration damping composite rubber mat plate used under railway rail and preparation method thereof

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 [0001] The invention relates to a rubber sheet, in particular to a composite rubber sheet used under railway rails and a preparation method thereof. Background technique [0002] The present railway rail structure is that a composite rubber backing plate formed by combining stainless steel sheet and common rubber backing plate is added between the rail and the sleeper to reduce the vibration between the rail and the sleeper when driving. As early as 1998, during the new round of rail overhaul of the railway approach bridge of the Nanjing Yangtze River Bridge, the original wooden sleepers were replaced, and concrete sleepers and seamless lines were laid. Designed by the Academy of Railway Sciences, composite rubber was added between the rails and the sleepers. backing plate. However, with the rapid acceleration of the railway, the vibration of the bridge foundation increases during high-speed driving. The displacement of the rail increases during high-speed ...
