Description
Technical field
The present invention relates to lubricating composition, especially a kind of environmental protection type biodegradable lubricating oil and its preparation process.
Background technology
Lubricating oil plays antiwear and antifriction, cooling in equipment operation and improves the indispensable key effects such as efficiency, but
It is that compatibility usually with environment is poor.The biological degradability of conventional mineral lubricating oil is poor, if in production, storage and transportation and using process
Middle generation leakage just pollutes the environment.Since mineral lubricating oil biological degradability is poor, in addition enhancing and the state of people's environmental consciousness
Family environmental regulation it is stringent, the research and development of Biodegradable lubricant oil is increasingly valued by people.Currently, can biology
Degradation lubricating oil has become the important component part of Green Chemistry and green engineering field.
Biodegradable lubricant oil refers to that can meet the requirement of mechanical equipment and in a short time by active micro-
Biological decomposition is the lubricating oil of carbon dioxide and water, it is typically incorporated into the row of environmental friendly lubricant.Environmental friendly lubricant
Performance include not only biodegradability, but also include the eco-toxicity of lubricant.Biological degradability and eco-toxicity are
Two different aspects, some noxious materials are also biodegradable, and non-toxic substance is generated after degradation；After some mass degradations
Product has stronger toxicity than original matter.Environmental friendly lubricant should ask biological degradability to get well, but require eco-toxicity and
Cumulative toxicity wants small.
There are two types of the approach for preparing Biodegradable lubricant oil at this stage, another one is being improved to base oil
It is to be improved to additive.
Such as United States Patent (USP) USP5888947 (Vegetable oil lubricants for internalcombustion
Engines and total loss lubrication.1999-03-30.) using the I. C. engine oil of high oleic acid vegetable oil development
With good heat conductivity, lubricity and biological degradability, the wherein mass fraction of high oleic acid vegetable oil is 68%~90%.
For another example in Master's thesis《It can promote the performance study of the biodegradable imidazolinyl lubricating additive of lubricating oil》(weight
Celebrating Polytechnics, 2011：The shadow of Long carbon chain imidazoline and its borate to atoleine performance 26-32.) is had studied in a text
It rings.This is research shows that the biodegradation promotor that the paper provides greatly improves the biodegradability of atoleine, together
When also improve antiwear and friction reduction property, antiseptic property and rustless property.
However, above-mentioned documents and materials are no to provide a kind of complete lubricant formula, only to base oil or its additive
It is improved to provide performance, however those skilled in the art know, lubricant oil composite simultaneously non-base oil and additive letter
Single superposition, effect can be also superimposed, therefore still need to explore a kind of good environmental protection type biodegradable lubricant formula.
Mineral lubricating oil is still occupied an important position in field of lubricant at present, and biological will not can be dropped in a long time
Solution lubricating oil is replaced, but the enhancing of the development and environmental consciousness with society, and Biodegradable lubricant oil will occupy more next
More consequence.
