Integrally-formed sleeper buffering composite part and preparation method and application thereof
The invention relates to an integrally-formed sleeper buffering composite part and a preparation method and application thereof, and belongs to the technical field of urban rail transit buffering. According to the invention, the nylon wire net is pre-embedded into the high-performance polyurethane cushion pad in advance, so that the exposed nylon wire net and the concrete sleeper prefabricated part can be molded by one-time casting in the production process of the concrete sleeper prefabricated part; the secondary processing of connecting the polyurethane buffer pad with the concrete sleeper prefabricated part through rivets, anchoring or sticking and the like in the construction process is avoided; the polyurethane buffer pad is firmly connected with the concrete sleeper prefabricated part, and the problem that the polyurethane buffer pad is not firmly bonded and falls off is solved; the polyurethane cushion pad and the concrete sleeper prefabricated part can be prepared in batches in a factory, and the preparation process is convenient and fast; the polyurethane cushion pad with the nylon wire net can be continuously produced in a large scale, and the production process is simple and convenient.
本发明涉及一种一体成型轨枕缓冲复合件及其制备方法和应用，属于城市轨道交通缓冲技术领域。本发明中，尼龙丝网是提前预埋至高性能聚氨酯缓冲垫中，可实现在混凝土轨枕预制件生产过程中，通过外露的尼龙丝网与混凝土轨枕预制件一次性浇注成型，避免了聚氨酯缓冲垫在施工过程中通过铆钉、锚固或者粘贴等方式与混凝土轨枕预制件连接的二次加工；聚氨酯缓冲垫与混凝土轨枕预制件连接牢固，不会出现粘接不牢脱落问题；聚氨酯缓冲垫与混凝土轨枕预制件可在工厂实现批量制备，制备工艺方便快捷；带有尼龙丝网的聚氨酯缓冲垫可实现连续大批量生产，生产工艺简便。
