Abstract
The invention discloses anti-wear lubricating oil, comprising base oil and an extreme-pressure anti-wear agent, wherein the concentration of the extreme-pressure anti-wear agent is 2-6mmol/100g; the extreme-pressure anti-wear agent is diethyl phosphate and/or dibutyl phosphate; preferably, the anti-wear lubricating oil comprises the base oil, the diethyl phosphate and the dibutyl phosphate; the concentration of the diethyl phosphate in the anti-wear lubricating oil is 1-3mmol/100g; and the concentration of the dibutyl phosphate is 1-3mmol/100g. The anti-wear lubricating oil is simple in formula, available in raw materials and excellent in abrasion resistance.
Description
Technical field
The present invention relates to a kind of lubricating oil, particularly relate to a kind of wearproof lubricant.
Background technology
Lubricating oil is used in reduce friction in all kinds automobile, mechanical means, protection machinery and the liquid of workpiece or semi-solid lubricants, mainly play lubrication, cooling, antirust, clean, seal and the effect such as buffering.
Lubricating oil is generally made up of base oil and additive two portions.Base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricating oil.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of wearproof lubricant.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of wearproof lubricant, comprise base oil and extreme pressure anti-wear additives, the concentration of described extreme pressure anti-wear additives is 2-6mmol/100g.
Described extreme pressure anti-wear additives is diethyl phosphite and/or dibutyl phosphite.
Preferably, described wearproof lubricant, comprise base oil and diethyl phosphite and dibutyl phosphite, the concentration of described wearproof lubricant phosphorous acid diethyl ester is 1-3mmol/100g, and the concentration of dibutyl phosphite is 1-3mmol/100g.
Adopt this area universal method, each raw material is mixed, wearproof lubricant of the present invention can be obtained.
Relative to prior art, the advantage major embodiment of technical solution of the present invention is: the present invention fills a prescription simply, and raw material is easy to get, and abrasion resistance is excellent.
Embodiment
Raw material: paraffinic based oil, viscosity index 87, kinematic viscosity 16mm when 37.8 DEG C
2/ s, sulfur-bearing 0.01%.Dibutyl phosphite, No. CAS: 1809-19-4.Diethyl phosphite, No. CAS: 762-04-9.
Embodiment 1:
Diethyl phosphite is added, obtained wearproof lubricant in paraffinic based oil.This makes in 100 grams of wearproof lubricants containing diethyl phosphite 4mmol.
Embodiment 2:
Dibutyl phosphite is added, obtained wearproof lubricant in paraffinic based oil.This makes in 100 grams of wearproof lubricants containing dibutyl phosphite 4mmol.
Embodiment 3:
Diethyl phosphite and dibutyl phosphite is added, obtained wearproof lubricant in paraffinic based oil.This makes in 100 grams of wearproof lubricants containing diethyl phosphite 2mmol and dibutyl phosphite 2mmol.
Test case:
Load is tested, room temperature, 1500r/min, 60s.
Wearing test 50 DEG C, load 15kg, 500r/min.
Blank example is 100% paraffinic based oil.
As seen from the above table, adding a certain amount of extreme pressure anti-wear additives in base oil is that after diethyl phosphite or dibutyl phosphite, four-ball tester loading test load significantly increases.In base oil, add diethyl phosphite or dibutyl phosphite separately, four-ball tester wearing test wear scar diameter declines to some extent, but fall is very little, and not obvious; Further employing diethyl phosphite and the composite extreme pressure anti-wear additives of dibutyl phosphite, wear scar diameter sharply declines, and abrasion resistance becomes very good.
Claims (3)
1. a wearproof lubricant, comprises base oil and extreme pressure anti-wear additives, and the concentration of described extreme pressure anti-wear additives is 2-6mmol/100g.
2. wearproof lubricant according to claim 1, is characterized in that: described extreme pressure anti-wear additives is diethyl phosphite and/or dibutyl phosphite.
3. wearproof lubricant according to claim 2, it is characterized in that, comprise base oil and diethyl phosphite and dibutyl phosphite, the concentration of described wearproof lubricant phosphorous acid diethyl ester is 1-3mmol/100g, and the concentration of dibutyl phosphite is 1-3mmol/100g.
