Abstract

The invention provides a rubber base plate for subway rail transit as well as a composition and a preparation method of the rubber base plate, and belongs to the field of rubber materials. The composition for the rubber base plate for the subway rail transit comprises 100 parts of matrix rubber, 20-100 parts of a filling agent, 0-5 parts of a silane coupling agent, 5-35 parts of an active agent, 0-15 parts of a plasticizer, 3-10 parts of a pigment, 1-3 parts of an anti-aging agent, 3-15 parts of a functional auxiliary agent, 0.3-2.5 parts of a vulcanizing agent and 2-8 parts of a vulcanization accelerator. Compared with a traditional black rubber base plate, the rubber base plate for subway rail transit prepared from the composition has the advantages that the shore hardness, tensile strength and other mechanical properties are remarkably improved, and the rubber base plate is suitable for various current rail transit road sections.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a composition for a rubber backing plate for subway rail transit, a rubber backing plate for subway rail transit made from the composition, and a preparation method for the rubber backing plate for subway rail transit. Background technique [0002] The rubber pad between the rail and the sleeper in rail transit is one of the important parts of the track. Since the rubber pad is the closest elastic element to the wheel-rail power system, it can buffer the vibration and impact of high-speed vehicles passing by, so it plays a direct and important role in the vibration and noise reduction of the track. [0003] At present, under-rail backing plates in China are generally made of black high-molecular polymer materials. The under-rail backing plate made of black polymer material generally has the following problems: 1. Poor mechanical properties, easy to be damaged under pressure; 2. I...
