Problems solved by technology

In addition, although hydraulic equipment is generally used in construction machinery, etc., if the friction coefficient of lubricating oil used for hydraulic oil is high, micro-stick-slip occurs in the sliding area of ​​the reciprocating module of the hydraulic cylinder, causing problems such as hydraulic Phenomena such as cylinder vibration, vibration, sharp sound or abnormal noise, making it impossible to accurately control hydraulic equipment

Abstract

The present invention provides a lubricating oil composition comprising a base oil, an aspartic acid derivative and an aliphatic amine compound. The lubricating oil composition is ideal as an industrial lubricating oil such as for example for a hydraulic working oil in hydraulic equipment. Primary amine, secondary amine, diamine, and / or tertiary amines may be employed for the aliphatic amine compound.

Description

technical field [0001] The present invention relates to lubricating oil compositions, especially lubricating oil compositions for use as industrial lubricating oils, especially for use as machine oils, hydraulic oils, turbine oils, compressor oils, gear oils, sliding surface oils, bearing oils Or the lubricating oil composition of the calibration oil. Background technique [0002] Lubricating oils used in mechanical equipment require the necessary rust resistance to maintain their performance. The reasons for this include the following: the temperature of the lubricating oil in the oil tank in mechanical equipment is raised and lowered depending on the conditions of use, which may cause condensed water to mix with the lubricating oil in the oil tank; Moisture mix. In order to obtain this rust resistance, aspartic acid ester or the like is used. See Japanese Patent Application Laid-Open No. 6-200268. [0003] Also, in recent years, industrial lubricating oil compositions ...
