The invention belongs to the technical field of motor train unit anti-icing and deicing, and discloses an anti-icing coating for vehicle-mounted bogie of motor train unit which is sequentially sprayedwith an insulating coating, a conductive heating coating and a hydrophobic wear-resistant coating from bottom to top. The insulating coating separates the conductive heating coating from the vehiclebody to avoid an accident of electric leakage, and is also used for heat insulation to reduce the conduction loss of heat into the bogie; the conductive heating coating is used for keeping the bogie at 0 DEG C or above and keeping the temperature of the bogie stable; and the hydrophobic wear-resistant coating is used for preventing molten water from adhering to the bogie, and is also used for preventing wind, sand and rainwater from eroding the bogie and protecting the insulating coating and the conductive heating coating on the inner side. According to the protection device, snow melting anddeicing are conducted through the conductive heating coating, severe snow accumulation and icing on the surface and the periphery of the bogie are prevented, the dynamic performance and the suspensionperformance of the bogie are guaranteed, and the safety, the stability and the high efficiency of a train running on snowy days are improved.

    本发明属于动车组防冰除冰技术领域,公开了一种动车组车载转向架防冰涂层,从下到上依次喷涂有绝缘涂层、导电发热涂层及疏水耐磨涂层;绝缘涂层将导电发热涂层与车体分离开,避免漏电的事故,还用于绝热,减少热量向转向架内部的传导损失;导电发热涂层用于保持转向架维持在0℃以上,维持转向架温度的稳定;疏水耐磨涂层用于避免融化后的水粘滞在转向架上,还用于避免风沙雨水侵蚀转向架,保护内侧的绝缘涂层、导电发热涂层。本发明通过导电发热涂层融雪除冰,防止转向架表面及周围发生严重积雪结冰,保证转向架的动力学性能和悬挂性能、提高列车在雪天运行的安全性及平稳性和高效性的保护装置。
