Wear, heat and aging-resistant lubricating oil for precision instrument and preparation method of wear, heat and aging-resistant lubricating oil

Abstract

The invention discloses wear, heat and aging-resistant lubricating oil for a precision instrument. The wear, heat and aging-resistant lubricating oil consists of the following raw materials in part byweight: 100 parts of composite base oil, 10-20 parts of pentaerythritol ester, 0.5-1.5 parts of dodecafluoroheptyl methacrylate, 1-3 parts of triethanolamine borate, 3-6 parts of sulfurized fatty acid ester, 1-4 parts of alkaryl calcium sulfonate, 0.3-0.8 part of a diethylbenzene coupling agent, 3-6 parts of an anti-friction lubricating additive and 2-7 parts of a modified additive. The wear, heat and aging-resistant lubricating oil disclosed by the invention has the beneficial effects that the high-quality and high-performance composite base oil is adopted to be compounded with the other modified raw materials, and the lubricating oil with high lubricating performance, high corrosion, rust and wear resistance, high high and low-temperature resistance stability, excellent heat and aging resistance and high sustainability is prepared through a simple and effective preparation method; and the lubricating oil disclosed by the invention is thick and fine liquid and is simple in processingmethod, convenient to use and suitable for the high-precision instrument.

Description

technical field [0001] The invention relates to the technical field of lubricating grease preparation, in particular to an anti-wear, heat-resistant and aging-resistant lubricating oil for precision instruments and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and society, all kinds of precision instruments have been widely concerned and developed. put forward higher requirements. During the operation of precision instruments, many parts need to be lubricated with lubricating grease to reduce the running friction / wear and / or poor contact between parts, or to reduce the risk of metal plating exposed to the air environment / in contact with the air oxidation. Affected by the operating characteristics of the precision instrument itself, its internal core control components are likely to generate more heat during operation. The existing lubricating oil used for precision instruments is easy to absorb heat, s...

Problems solved by technology

Affected by the operating characteristics of the precision instrument itself, its internal core control components are likely to generate more heat during operation. The existing lubricating oil used for precision instruments is easy to absorb heat, soften, lose, and volatilize when heated. Or thermal aging occurs, which seriously reduces the lubrication performance; and many precision instruments need to operate in a short-term / long-term low-temperature environment, such as the outdoor environment in the north in winter, the lubricating grease used should have good low-temperature resistance; at the same time, used in Lubricating grease for precision instruments should have good oxidation resistance / thermal oxidation resistance, water resistance and corrosion resistance
