摘要： The present application relates to a grease composition, more particularly, to a grease composition for a constant velocity joint or a ball joint for a vehicle and, even more particularly, to a grease composition containing 70 to 80 parts by weight of a paraffinic base oil; 7.5 to 17.5 parts by weight of a urea-type thickener from a reaction of 5 to 9 parts by weight of methylene diphenyl diisocyanate, 2 to 5 parts by weight of alicyclic amine, and 0.5 to 3.5 parts by weight of aniline; 4 to 7 parts by weight of an extreme pressure-wear additive; and 1 to 3 parts by weight of a lubricant containing animal and vegetable oils. According to the present application, grease that has excellent high-temperature and low-temperature characteristics, has excellent durability to allow long-term lubrication, contributes greatly to temperature rise prevention by reducing sliding friction, and has the optimal effect in constant velocity joints or ball joints for vehicles, gears for steel and other industries, bearings, and particularly lubrication sites requiring extreme pressure, can be provided.
摘要翻译：本申请涉及一种润滑脂组合物，更具体地说，涉及一种用于车辆等速万向节或球窝接头的润滑脂组合物，更具体地说，涉及一种含有70至80重量份的石蜡基础油 ; 7.5〜17.5重量份尿素型增稠剂，由5〜9重量份亚甲基二苯基二异氰酸酯，2〜5重量份脂环族胺和0.5〜3.5重量份苯胺的反应; 4〜7重量份的极压耐磨添加剂; 和1至3重量份含有动植物油的润滑剂。根据本申请，具有优异的耐高温和低温特性的润滑脂具有优异的耐久性以允许长期润滑，通过减少滑动摩擦来大大提高防止温度升高，并且在等速万向节或可以提供用于车辆的球接头，用于钢和其它工业的齿轮，轴承，特别是需要极压的润滑部位。
