Abstract
The invention discloses a lubricating oil modified additive. The lubricating oil modified additive comprises the following ingredients in parts by mass: 30-35 parts of cobalt naphthenate, 45-55 parts of lead isocaprylate, 1.6-1.8 parts of an alpha-olefin copolymer pour point depressant, 1-3 parts of a non-ionic surface activator, 1.5-2.5 parts of a cleaning agent, 2-2.5 parts of a dispersant, 0.5-1.2 parts of an extreme-pressure anti-wear agent, 0.6-0.8 part of a rust inhibitor, 0.3-0.6 part of an antioxidant, 0.1-0.15 part of a pour point depressant, 20-80 PPM of an antifoaming agent, 5-9 parts of a tackifier, 0.6-0.8 part of an oxidation and corrosion inhibitor, 3-5 parts of a viscosity index improver, 0.1-0.2 part of an emulsion breaker, 0.1-1 part of nanometer graphite and 10-15 parts of nanometer zinc oxide. The lubricating oil modified additive contains a certain quantity of surface activator, in favor of clearing metallic powder and other deposits, deposited on a friction surface and keeping an oil film formed on the friction surface clean, thereby improving lubricating effect, lowering mechanical wear and prolonging the running life of a machine.
Description
Technical field
The present invention relates to a kind of additive for modifying lubricating oil, belong to technical field of lubricating oil.
Background technology
Progress along with technology, the manufacturing accuracy of various machineries also improves constantly, correspondingly also more and more higher to the performance requriements of lubricating oil, in all-purpose engine oil, no matter be steam turbine oil, bavin machine oil, add Hangzhoupro extreme pressure, Hangzhoupro wearing and tearing that the better property-modifying additive of a kind of lubricity improves oil film, thus meet lubricated in excellent condition, this to improve machine security, increasing the service life becomes problem in the urgent need to address at present.
Summary of the invention
First technical problem to be solved by this invention is: provide a kind of consistency good, the additive for modifying lubricating oil of good stability.
For addressing the above problem, the technical solution used in the present invention is: a kind of additive for modifying lubricating oil, by mass fraction, consist of: cobalt naphthenate 30-35 part, the plumbous 45-55 part of isocaprylic acid, alpha-olefin copolymer pour point depressant 1.6-1.8 part, nonionogenic tenside 1-3 part, purification agent 1.5-2.5 part, dispersion agent 2-2.5 part, extreme pressure anti-wear additives 0.5-1.2 part, rust-preventive agent 0.6-0.8 part, oxidation inhibitor 0.3-0.6 part, pour point depressant 0.1-0.15 part, foam reducing composition 20-80PPM, tackifier 5-9 part, oxidation and corrosion inhibitor 0.6-0.8 part, viscosity index improver 3-5 part, emulsion splitter 0.1-0.2 part, nano-graphite 0.1-1 part, nanometer ZrO
210-15 part.
Described nano-graphite granularity is 15-40nm.
Described nanometer ZrO
2particle diameter is 20-50nm.
Beneficial effect of the present invention: the present invention contains a certain amount of tensio-active agent, be conducive to remove metal-powder and other settling of being deposited on friction surface, make the oil film that friction surface forms keep clean, thereby improve lubricant effect, reduce mechanical wear, improve the operation life of machine; Additive ZrO
2particle is enriched in cracks of metal surface place, thereby at surface of friction pair, sets up the lubricant film of one deck selfreparing, has the advantages that anti-attrition and self-healing properties are good.Adopt preparation method of the present invention, its finished product dispersing property is good, good stability, and anti-wear and wear-resistant performance is good.In addition, because nano-graphite is more easily sprawled film forming at surface of friction pair, further strengthened the lubricity of lubricant.
