Abstract
The invention discloses nano graphite lubricating oil, comprising the following components in parts by weight: 60-70 parts of 650SN base oil, 10-12 parts of 250BS base oil, 18-23 parts of 150BS base oil, 1.5-2.5 detergent, 2-2.5 parts of dispersant, 0.5-1.2 parts of anti-wear reagent at extreme pressure, 0.6-0.8 part of rust inhibitor, 0.3-0.6 part of antioxidant, 0.1-0.15 part of pour point depressant, 20-80ppm of antifoaming agent, 5-9 parts of tackifier, 0.6-0.8 part of oxidation and corrosion inhibitor, 3-5 parts of viscosity index improver, 0.1-0.2 part of demulsifier, 0.1-1 part of nano graphite, and 10-15 parts of nano ZrO2. According to the lubricating oil disclosed by the invention, ZrO2 particles are gathered on the defects at the metal surface by adding ZrO2, so that a layer self-repairing lubricating film is built on the surface of a friction pair, and the lubricating film has the characteristics of being good in anti-attrition and self-repairing performances. By adopting the preparation method disclosed by the invention, the product is good in dispersing performance, good in stability, and good in anti-wear and friction reduction properties. In addition, the nano graphite is more easily paved into a film on the surface of the friction pair, and the lubricating property of a lubricant is further enhanced.
Description
Technical field
The present invention relates to a kind of nano-graphite lubricant, belong to technical field of lubricating oil.
Background technology
At present, most widely used solid lubricant is graphite and molybdenumdisulphide, these two kinds of materials have the inoganic solids lubricant of laminate structure, shearing resistance is low, easily be attached to the solid lubricant film that substrate surface forms low-friction coefficient and high adhesion strength, and easily on mating material surface, form transfer film and play the effect that reduces friction and wear, this material also can be made matrix material with other material and use except can be used alone, belong to the antifriction material of a class, they mainly use in lubricating grease and other industry, and for lubricating oil till now or a blank, its major cause is the proportion that can't resolve graphite, the proportion of graphite is more than 2, and lubricating oil is only in 0.9, the two differs too large, as long as graphite produces on foot heavy in being added to lubricating oil, do not have its due lubrication, thereby limited this solid lubricant of graphite applying in lubricating oil field.
Summary of the invention
First technical problem to be solved by this invention is: provide a kind of consistency good, the graphite lubricating oil (GLO) that good stability lubricity is good.
For addressing the above problem, the technical solution used in the present invention is: a kind of graphite lubricating oil (GLO), by mass fraction, consist of: 650SN base oil 60-70 part, 250BS base oil 10-12 part, 150BS base oil 18-23 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: lubricating oil of the present invention, passes through ZrO
2add, make 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.
