Abstract

camada de lastro de poliuretano, método para preparar o mesmo e uso do mesmo a presente invenção refere-se a uma camada de lastro de poliuretano, ao método para preparar a mesma, e uma ferrovia que compreende a camada de lastro de poliuretano. a camada de lastro de poliuretano apresentada na presente invenção compreende uma camada de lastro preenchida com poliuretano e uma camada de proteção externa de poliuretano. em que a camada de lastro preenchida com poliuretano compreende lastros e espuma do poliuretano preenchendo o espaço entre os lastros. a camada de lastro de poliuretano apresentada na presente invenção pode reduzir a probabilidade de o lastro se romper , se deslocar e rachar sob carga pesada, e separa o trilho de lastro do ambiente exterior para impedir que a chuva, a neve e resíduos penetrem no espaço interno do leito do trilho de lastro. além disso, a camada de lastro de poliuretano pode proteger a espuma de poliuretano que preenche os lastros contra a água no ambiente exterior para evitar a hidrólise . a camada de lastro de poliuretano apresentada na presente inveção pode ser usada no leito do trilho de lastro de ferrovias para ampliar de maneira significativa o ciclo de manutenção do leito do triho , e economizar o custo de manutenção de maneira significativa,
