Composite structure sleeper with high weather resistance and high strength and preparation method thereof
The invention discloses a composite structure sleeper with high weather resistance and high strength and a preparation method thereof. The sleeper is used as a matrix, and the outer surface of the sleeper matrix is coated with a layer of compact polyurethane composite film by utilizing the excellent bonding performance of polyurethane, so that the impact resistance, toughness, strength and weatherresistance of the sleeper are improved; the surface of the sleeper is dip-coated with a layer of polyurethane solution, and meanwhile, the problems of difficult uniform distribution of fibers and poor compatibility with resin in the synthetic sleeper are solved, so that the bonding strength of the sleeper matrix and the polyurethane composite film is improved, the service life of the sleeper is prolonged, and the stability of the sleeper is improved; the sleeper prepared by the invention has the advantages of high strength, no toxicity, environmental protection, decay resistance, long servicelife, fire resistance, flame retardance, convenience in installation and good elasticity, can effectively absorb vibration during train running, reduces the vibration and noise pollution of a train to a roadbed, improves the running stability of the train, and has good economic benefits and market prospects.
本发明公开了一种高耐候性和高强度的复合结构轨枕及其制备方法，以轨枕为基体，利用聚氨酯优异的粘结性能在轨枕基体的外表面包覆一层致密的聚氨酯复合薄膜，以提高轨枕的抗冲击性、韧性、强度和耐候性；并通过在轨枕表面浸涂一层聚氨酯溶液，同时解决了合成轨枕中，纤维均匀分布难和与树脂相容性差的问题，以提升轨枕基体与聚氨酯复合薄膜的结合牢度，从而延长轨枕的使用寿命及稳定性；本发明制得的轨枕具有强度高、无毒环保、耐腐朽、使用寿命长、防火阻燃、安装方便，同时具有很好的弹性，可有效的吸收火车行驶中的震动，减少了列车对路基的振动和噪音的污染，提高了火车行驶的稳定性，具备良好的经济效益及市场前景。
