Problems solved by technology

However, how to overcome the problems of poor high-temperature oxidation stability, low-temperature fluidity, and poor hydrolytic stability of vegetable oils has become a major obstacle restricting the development of bio-based lubricants.
In addition, during the use of lubricating oil, due to high temperature and oxidation, the lubricating oil will undergo oxidative degradation, produce acidic substances and carbon deposits, which will greatly affect the lubricating performance of the lubricating oil and shorten the service life of the lubricating oil. And the smooth operation of precision instruments using lubricating oil; therefore, how to improve lubricating oil products in order to improve the lubrication efficiency of instruments and achieve the purpose of energy saving and emission reduction has become one of the hot spots in lubricating oil research

Abstract

The invention relates to high temperature-resistant low-carbon cleaning-type lubricating oil. The high temperature-resistant low-carbon cleaning-type lubricating oil comprises the following raw materials in parts by weight: base oil comprising 100 parts of modified palm liquid oil, 5-10 parts of pentaerythritol ester, and 1-3 parts of poly alpha olefins; and a property-modifying additive comprising 0.5-3 parts of a basic neutralizer, 0.2-0.5 parts of T704 zinc naphthenate, 2-4 parts of calcium alkylphenol disulfide, 0.2-0.6 parts of heptadecene imidazoline, 1-3 parts of ethylene glycol amide oleate, 0.5-1.5 parts of castor oil alkanolamide borate, 0.3-0.7 parts of triazole fatty acid amine salt, 0.1-0.3 parts of alkanolamide, and 2-6 parts of iso-octyl palmitate. The high temperature-resistant low carbon cleaning-type lubricating oil has good oxidation stability and self-cleaning performance, the low temperature fluidity during a usage process is good, at the same time, the high temperature-resistant low-carbon cleaning-type lubricating oil has good environmental protection performance, and has high economic value and social value.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high-temperature-resistant, low-carbon and clean lubricating oil. Background technique [0002] As people's awareness of environmental crisis is increasing, it is generally recognized that the existing large amount of mineral-based lubricating oils have become more and more serious environmental pollution problems due to seepage, leakage, spillage and improper handling during production, use and discharge. , from the trend of social development, low-carbon, environmentally friendly lubricants will gradually replace the existing mineral-based lubricants. [0003] Environmentally friendly lubricating oil refers to lubricating oil that can be decomposed into water and carbon dioxide by active microorganisms in a relatively short period of time. It has the following characteristics: it has good lubricating performance and can reduce environmental pollution by saving energy ...
