    摘要: The present invention provides a polyurethane elastomer ballast mat and the preparation thereof, and a railway track bed and railway facilities using the same. The polyurethane elastomer ballast mat according to this invention comprises a reaction product prepared by spraying a reaction system comprising a polyisocyanate, a polyol, a chain extender, a blowing agent and a catalyst, on the surface of a railway roadbed or on one surface of a ballast mat shielding to conduct a reaction. The technical solution of the present invention makes it possible to provide ballast mats with different mechanical properties, shapes, thicknesses and sizes, depending on particular installation conditions, in order to adapt to various requirements for installation and use in railway construction.
