    • PROBLEM TO BE SOLVED: To provide a lubricating grease composition excellent in endurance at high temperatures and having good operability at low temperatures.SOLUTION: There is provided the lubricating grease composition usable in a cold district falling to be -30°C and provided by adding a thickener to a mixture base oil comprising (A) a perfluoropolyether oil having kinematic viscosity (40°C) of 150-1,500 mm/sec and represented by general formula: RfO[CF(CF)CFO](CFO)Rf (wherein, Rf is a 1-5C perfluoroalkyl group; (a) is 15-150; c is 0 or an integer of ≥1; and CF(CF)CFO and CFO are randomly bonded in the main chain) and (B) a perfluoropolyether oil having a kinematic viscosity (40°C) of 150-1,000 mm/sec and represented by general formula: RfO(CFCFO)(CFO)Rf (wherein, Rf is the same as defined above; m+n=20-200; m:n=(10-90):(90-10); and CFCFO and CFO are randomly bonded in the main chain), to be 15-30 wt.% rate in the composition total amount.
    • 要解决的问题:提供在高温下耐久性优异并且在低温下具有良好可操作性的润滑脂组合物。 解决方案:提供润滑脂组合物,其可用于在-30℃的冷区中,并且通过向包含(A)具有运动粘度(40℃)的全氟聚醚油的混合物基础油中添加增稠剂而提供, 为150-1,500mm 2 /秒,由通式RfO [CF(CF 3 )CF 2 O] a (CF 2 O) c (其中,Rf为1-5C全氟烷基;(a)为15-150; c为0或≥1的整数; CF(CF 3 SB>)CF 2 O和CF 2在主链中随机键合)和(B)具有 150〜1,000mm的运动粘度(40℃),由通式RfO(CF 2 CF 2 O) m (CF 2 O) 2 O和CF 2 O随机地结合在 主链),在组成总量中为15-30重量%。 版权所有(C)2013,JPO&INPIT
