Abstract
The invention discloses a kind of wearproof lubricant, including base oil and extreme pressure anti-wear additives, the concentration of described extreme pressure anti-wear additives is 2 6mmol/100g, and described extreme pressure anti-wear additives is diethyl phosphite and/or dibutyl phosphite.Preferably, described wearproof lubricant, including base oil and diethyl phosphite and dibutyl phosphite, the concentration of described wearproof lubricant phosphorous acid diethylester is 1 3mmol/100g, and the concentration of dibutyl phosphite is 1 3mmol/100g.Inventive formulation is simple, and raw material is easy to get, and abrasion resistance is excellent.
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 all kinds automobile, in plant equipment to reduce friction, protection machinery
And the liquid of workpiece or semisolid lubricants, act primarily as lubrication, cooling, antirust, cleaning,
Seal and buffering etc. acts on.
Lubricating oil is typically made up of base oil and additive two parts.Base oil is the master of lubricating oil
Wanting composition, decide the fundamental property of lubricating oil, additive then can make up and improve basis oiliness
Deficiency in terms of Neng, gives some new performance, is the important component part of lubricating oil.
Content of the invention
For the deficiencies in the prior art, the technical problem to be solved is to provide a kind of anti-
Tribology lubricating oil.
For solving above-mentioned technical problem, the present invention is achieved through the following technical solutions:
A kind of wearproof lubricant, including base oil and extreme pressure anti-wear additives, described extreme pressure anti-wear additives
Concentration is 2-6mmol/100g.
Described extreme pressure anti-wear additives is diethyl phosphite and/or dibutyl phosphite.
Preferably, described wearproof lubricant, including base oil and diethyl phosphite and phosphorous acid
Dibutyl ester, the concentration of described wearproof lubricant phosphorous acid diethylester is 1-3mmol/100g, sub-
The concentration of dibutylphosphoric acid ester is 1-3mmol/100g.
Use method generally in the art, each raw material is mixed, can be prepared by the anti-of the present invention
Tribology lubricating oil.
Relative to prior art, the advantage of technical solution of the present invention is mainly reflected in: the present invention joins
Side is simple, and raw material is easy to get, and abrasion resistance is excellent.
Detailed description of the invention
Raw material: paraffine base crude oil, Viscosity Index 87, dynamic viscosity 16mm when 37.8 DEG C2/ s, sulfur-bearing
0.01%.Dibutyl phosphite, No. CAS: 1809-19-4.Diethyl phosphite, No. CAS:
762-04-9。
Embodiment 1:
Add diethyl phosphite in paraffine base crude oil, prepare wearproof lubricant.This makes 100
4mmol containing diethyl phosphite in gram wearproof lubricant.
Embodiment 2:
Add dibutyl phosphite in paraffine base crude oil, prepare wearproof lubricant.This makes 100
4mmol containing dibutyl phosphite in gram wearproof lubricant.
Embodiment 3:
Add diethyl phosphite and dibutyl phosphite in paraffine base crude oil, prepare anti-wear lubricating
Oil.This makes 2mmol containing diethyl phosphite and phosphorous acid two fourth in 100 grams of wearproof lubricants
Ester 2mmol.
Test case:
Load is tested, room temperature, 1500r/min, 60s.
Wear test 50 DEG C, load 15kg, 500r/min.
Blank example is 100% paraffine base crude oil.
As seen from the above table, adding a certain amount of extreme pressure anti-wear additives in base oil is diethyl phosphite
Or after dibutyl phosphite, four-ball tester load test load is significantly increased.In base oil individually
Add diethyl phosphite or dibutyl phosphite, four-ball tester wear test wear scar diameter under
Fall, but fall is very little, and inconspicuous；Use diethyl phosphite and phosphorous acid further
The compounding extreme pressure anti-wear additives of dibutyl ester, wear scar diameter drastically declines, and abrasion resistance becomes very good.
Claims (1)
