Integrally-formed sleeper vibration reduction composite part and preparation method and application thereof
The invention relates to an integrally-formed sleeper vibration reduction composite part and a preparation method and application thereof, and belongs to the technical field of urban rail transit vibration reduction. According to the invention, the nylon wire net is pre-embedded into the high-performance polyurethane anti-vibration pad in advance, so that the exposed nylon wire net and the concrete trapezoidal sleeper prefabricated part can be molded by casting at one time in the production process of the concrete trapezoidal sleeper prefabricated part; the secondary processing that the polyurethane anti-vibration pad is connected with the concrete trapezoidal sleeper prefabricated part through rivets, anchoring or pasting and the like in the construction process is avoided; the high-performance polyurethane anti-vibration pad is adopted to replace a rubber or conventional polyurethane anti-vibration pad, so that the vibration reduction performance of the polyurethane anti-vibration pad is greatly improved, and the service life of the polyurethane anti-vibration pad is greatly prolonged; the polyurethane anti-vibration pad is firmly connected with the concrete trapezoidal sleeper prefabricated part, and the problem that the polyurethane anti-vibration pad is not firmly bonded and falls off is solved; the polyurethane anti-vibration pad and the concrete trapezoidal sleeper prefabricated part can be prepared in batches in a factory, and the preparation process is convenient and rapid; the polyurethane anti-vibration pad with the silk screen and the back plate 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减振复合件及其制备方法和应用，属于城市轨道交通减振技术领域。本发明中，尼龙丝网是提前预埋至高性能聚氨酯减振垫中，可实现在混凝土梯形轨枕预制件生产过程中，通过外露的尼龙丝网与混凝土梯形轨枕预制件一次性浇注成型，避免了聚氨酯减振垫在施工过程中通过铆钉、锚固或者粘贴等方式与混凝土梯形轨枕预制件连接的二次加工；采用高性能聚氨酯减振垫替代橡胶类或常规聚氨酯类聚氨酯减振垫，大幅度提高了聚氨酯减振垫的减振性能和服役寿命；聚氨酯减振垫与混凝土梯形轨枕预制件连接牢固，不会出现粘接不牢脱落问题；聚氨酯减振垫与混凝土梯形轨枕预制件可在工厂实现批量制备，制备工艺方便快捷；带丝网和背板的聚氨酯减振垫可实现连续大批量生产，生产工艺简便。
