GREASE LUBRICANT Russian patent published in 2010 - IPC C10M169/04 C10M117/02 C10M107/10 C10M133/44 

Abstract RU 2391386 C1

FIELD: chemistry.

SUBSTANCE: invention relates to grease lubricant composition meant for main sliding friction units of motorcars. The composition contains the following in wt %: 12-hydroxystearic acid 14-20; acetic acid 4-5.8; synthetic fatty acids of the C5-C6 fraction or hexanoic acid 1.5-2.5; barium hydroxide octahydrate up to complete saponification; N-(diethylaminomethyl)benzotriazole 0.01-0.3; synthetic polyalphaolefin oil with viscosity of 5-12 cS at 100°C - up to 100.

EFFECT: higher hydrolytic stability (resulting from absence of free organic acids and neutral reaction of the medium with the lubricant), improved anti-corrosion properties with respect to copper and wider operating temperature range of the lubricant (from minus 40°C to 150°C).
