固体轮轨、轮缘润滑剂
摘要：
本发明涉及火车轮轨系统的润滑剂，是将20～70％的石墨粉、二硫化钼和氮化硼2～5％的三氧化二锑和三水合氧化铝，掺入30～80％高分子聚合物中，于20～90℃下固化成型。本发明物理化学性质稳定，使用过程中和车轮轮缘始终是接触的，会因摩擦而在轮缘表面形成一层吸附薄膜，避免轮轨之间的硬接触及干摩擦状态，增加车头的有效牵引力。
摘要（英）：

A solid lubricant for train wheel-rail system is prepared by adding graphite powder, MoS2, boron nitride, Sb2O3 and hibbsite to high-molecular polymer and solidifying at 20-90 deg.C. It has stable physical and chemical properties. During its application, it is always contacted with wheel and forms a layer of film on surface of wheel, so avoiding hard contact and dry friction between wheel and rail and increasing tractive force.
