Abstract
The invention relates to biodegradable lubricating grease which comprises the following components according to mass percent: 80%-85% of base oil, 12%-10% of a thickening agent and 8%-5% of other additives. Vegetable oil, fatty acid ester and poly-alpha-olefin (PAO) are compounded to form the base oil of the biodegradable and environment-friendly lubricating grease, and fatty acid or animal and vegetable oil lithium calcium soap is taken as the thickening agent. The biodegradable lubricating grease composition is good in combination property, and all performance indexes of the composition reach using requirements; organic copper and organic molybdenum are compounded to form an antioxidant, so that the biodegradable lubricating grease is good in internal synergistic effect, and the wear resistance and the high-temperature oxidation stability of the grease can be improved; and mechanical noises can be effectively reduced since the organic molybdenum is added into the lubricating grease. The biodegradable lubricating grease can meet increasingly stringent environmental protection and energy conservation requirements and is suitable for lubricating and sealing of various mechanical friction pairs.
Description
Technical field
The present invention relates to a kind of energy and satisfy the Biodegradable Lubricating Greases that harsh day by day environmental protection and energy saving required, were applicable to the lubricated and sealing of all kinds of mechanical friction pairs.
Background technology
Lubricating grease is a kind of lubricant between liquid and solid, its output in whole lubricated product proportion far away from lubricating oil.But the grease lubrication performance is better than lubricating oil, and when the normal temperature state, it can be adsorbed on the metallic surface and not flow; Be heated or during mechanical effect, lubricating grease is thinning, can be as liquid lubrication friction surface, when heat effect and mechanical effect diminish when disappearing gradually, lubricating grease recovers its thick state.Because lubricating grease has this singularity, therefore, is widely used in fields such as industry, agricultural, communications and transportation, national defense industry, and becomes one of the most rising lubricant.
It is base oil (accounting for 70%～90%), viscosifying agent (accounting for 10%～20%) and additive (below 10%) that lubricating grease is mainly formed.For now, the used base oil of lubricating grease mainly is isolated mineral oil in the oil, and the biological degradability of mineral base oil is poor, and contains objectionable impuritiess such as polycyclic aromatic hydrocarbons.In the lubricating grease use, unavoidably can be because of infiltration, leak and overflow etc. and enter environment, cause pollution, destroy ecotope, jeopardize HUMAN HEALTH.Mineral oil grease not only is difficult to biological degradation in physical environment, and wherein contained various additive major parts be not poisonous be exactly that environment is harmful to.In addition, because lubricating grease recycles than being easier to unlike lubricating oil, therefore, along with people's environmental protection consciousness strengthens day by day, the problem of environmental pollution that lubricant causes has caused people's extensive concern.The lubricating grease that research has biodegradability will become the breach that solves the destruction ecological environment problem.
In recent years, along with developing rapidly and progress of China's industry manufacture level, the mechanization degree of all trades and professions improves constantly, and will use and consume a large amount of lubricating grease every year, causes the pollution to environment, soil and water body, destroys ecotope.Government department also begins more and more to pay close attention to the pollution problem that lubricating grease produces environment; For avoiding away polluting earlier the old road of afterwards administering, adapt to the development of society, and the requirement of satisfying the environmentally friendly type lubricating grease of client, the environmentally friendly grease Products Development is necessary fully.From the trend of present lubricant development, existing petroleum-type lubricant will progressively be replaced by environmentally friendly lubricant comprehensively.Environmentally friendly lubricant also must become one of following lubricating grease development trend.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Biodegradable Lubricating Greases with good high and low temperature, sticking warm nature, oxidation stability, mechanical stability, erosion resistance, water repelling property, abrasion resistance and outstanding biological degradability.
The present invention solves the problems of the technologies described above with following technical scheme: adopt vegetables oil, fatty acid ester and poly-alpha olefins (PAO) compound as base oil, lipid acid and vegetable and animals oils lithium calcium soap are viscosifying agent, cooperate multiple composite additive, its each constituent mass percentage ratio is:
| Component | Content (mass percent) |
| Base oil | 80%～85% |
| Viscosifying agent | 10%～12% |
| Extreme pressure anti-wear additives | 1%～2% |
| Oxidation inhibitor | 2%～4% |
| Rust-preventive agent | 0.3%～0.8% |
| Weighting agent | 0.6%～1.2% |
Base oil is that vegetables oil, 50%～30% fatty acid ester and 20%～30% poly-alpha olefins (PAO) three of mass ratio 30%～40% is compound.
Viscosifying agent is lipid acid and vegetable and animals oils lithium calcium soap, and its mass ratio is (1:1).
Extreme pressure anti-wear additives is that di-n-butyl phosphite and 70%～60% the benzyl disulfide thing of mass ratio 30%～40% is compound.
Oxidation inhibitor is that alkenyl succinic acid copper and 50%～40% the dialkyl dithiophosphoric acid oxygen molybdenum oil-soluble organic molybdenum of mass ratio 50%～60% is compound.
Rust-preventive agent is that benzotriazole and 50%～60% the morpholine analog derivative of mass ratio 50%～40% is compound.
Weighting agent is graphite.
The remarkable advantage of Biodegradable Lubricating Greases of the present invention has:
1. good combination property, every performance index all reach service requirements.It has good high and low temperature, sticking warm nature, oxidation stability, mechanical stability, erosion resistance, water repelling property, abrasion resistance and outstanding biological degradability; Be applicable to the lubricated and sealing of all kinds of mechanical friction pairs.
