Abstract

The invention provides oil-gas lubricating oil which comprises the following components in percentage by weight: 75-90% of polyester type base oil, 6-20% of other types of base oil, 0.3-3% of antioxidant, 0.01-2% of antirusting agent, 0.5-3% of oiliness improver, 1-5% of extreme pressure antiwear agent and 0.01-0.5% of anti-foaming agent, wherein other types of base oil is one or more than one of synthetic ester, alkyl benzene and alkyl naphthalene. The provided oil-gas lubricating oil has strong universality, is not easy to coke at high temperature and has excellent high temperature performance and good lubricating property. The oil-gas lubricating oil not only can be applied to various bearings of an oil-gas lubricating device, gear cases with various loads, worm gears, worms, locomotive wheel rims, rail cases and the like, but also can be used as ordinary gear oil. Moreover, the oil-gas lubricating oil can be used both in summer and in winter and in southern region and northern region. The oil-gas lubricating oil has strong cleaning performance and can effectively prevent coked matter from blocking oil pipelines.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an oil-gas lubricating oil and a production method thereof. Background technique [0002] Oil-air lubrication technology is an emerging technology, that is, gas-liquid two-phase fluid cooling and lubrication technology. It has obvious advantages over dry oil lubrication, thin oil lubrication and oil mist lubrication in the corresponding equipment, and has a broad development prospect. . At present, there is still a big gap between my country's lubrication technology level and the international advanced level as a whole. The promotion and application of oil-air lubrication technology has positive significance for promoting the improvement of my country's lubrication technology level. [0003] Oil-air lubrication first appeared at the end of the 19th century, when steam engines were quickly applied to various occasions. Due to factors such as steam existing between the piston and t...
