Description
Technical Field
The invention belongs to the technical field of lubricating oil, and particularly relates to biodegradable lubricating grease.
Background
Lubricating oil plays indispensable key roles in wear resistance, friction reduction, cooling, efficiency improvement and the like in equipment operation, but is generally poor in compatibility with the environment. The traditional mineral lubricating oil has poor biodegradability, and can pollute the environment if leakage occurs in the processes of production, storage, transportation and use. Due to the poor biodegradability of mineral lubricating oil, the enhancement of environmental awareness of people and the strictness of national environmental regulations, the research and development of biodegradable lubricating oil are more and more paid more attention by people.
Biodegradable lubricating oils have become an important component in the fields of green chemistry and green engineering at present. Biodegradable lubricating oil is lubricating oil which can meet the use requirements of mechanical equipment and can be decomposed into carbon dioxide and water by active microorganisms in a short time, and is generally included in the list of environmentally friendly lubricants. The properties of environmentally friendly lubricants include not only biodegradability but also ecotoxicity of the lubricant. Biodegradability and ecological toxicity are two different aspects, and some toxic substances can also be biodegraded to generate non-toxic substances after degradation; the degraded product of some substances has stronger toxicity than the original substance. Environmentally friendly lubricants require both good biodegradability and low ecotoxicity and toxicity accumulation.
Biological lubricating oils, which may also be referred to as bio-based environmental friendly lubricating oils, refer to lubricating oils derived in part or in whole from biological resources or renewable agricultural or forestry resources. Besides the characteristics of mineral lubricating oil, biological lubricating oil also has attracted attention because of the advantages of renewable raw materials, biodegradability, small toxic action and the like. Lubricating oils are classified into three major categories, mineral oils, synthetic oils and natural vegetable oils, depending on the base oil. The vegetable oil-based lubricating oil is an environmentally friendly lubricating oil such as soybean oil, corn oil, rapeseed oil, cottonseed oil, and the like.
Although natural vegetable oils can be used directly as lubricating oils, their use is very limited because of their poor oxidative stability. The synthetic lubricating oil mainly comprises synthetic hydrocarbon, synthetic ester, polyether and the like. Of these, synthetic ester oils are the most widely studied. According to investigation, in the global lubricating oil application market, the proportion of mineral oil is as high as about 85%, vegetable oil accounts for about 2%, and the rest is synthetic oil. The current commercial degradable lubricating oil and lubricating grease use a large amount of modified vegetable oil, but the cost of the modified vegetable oil is too high, and the lubricating property and the service life of the modified vegetable oil are shorter than those of mineral lubricating oil; when the synthetic oil and the mineral oil are compounded, the degradation period is long, the degradation is not thorough, and the environment toxicity is realized.
