Abstract
A kind of lubricating composition is in selected mineral oil, adds sanitas, anti-friction composition and extreme pressure agent and forms, and its Specifeca tion speeification is: proportion 0.84～0.85, close flash point 〉=165 ℃, kinematic viscosity 8.5～9.0 centistokes (40 ℃).Oil film critical loading 〉=80kg.Practice shows, this is suitable for nonferrous materials precision sizing such as wear-resistant aluminum alloy especially and uses, economical and the high flash point, the low viscosity extreme pressure property machining oil that are easy to get.
Description
The present invention relates to a kind of lubricating composition, be suitable for the precision cutting lubricating and cooling agent as wear-resisting nonferrous materials (for example silumin) especially, it belongs to the petroleum cuts base-material is the lubricating composition class of feature.
Along with the progress of China's science and technology, use the occasion of wear-resisting nonferrous materials (for example silumin etc.) also more and more in the mechanical industry.These materials are mechanical workout, and especially precision cutting has suitable difficulty, not only will be with specific cutting tool, but also need the specific lubricating and cooling agent of adapted, otherwise can't satisfy the requirement of aspects such as precision and surface quality.If the lubricating and cooling agent when doing above-mentioned machining with emulsion commonly used, then working life is extremely short; And use kerosene or machine oil adds kerosene, and not only the lubricity in the processing is poor, and the health to the operator has detrimentally affect simultaneously.In a word, this is not obtain the problem that satisfactorily resolves at home.
Purpose of the present invention provides a kind of lubricating composition that is suitable for especially as nonferrous materials precision cutting lubricating and cooling agents such as wear-resistant aluminum alloys, to fill up domestic blank; This lubricating composition not only will satisfy processing request fully, and should have concurrently be easy to the preparation, lower-cost advantage.
Technical scheme of the present invention is: add sanitas, low friction compound and extreme pressure agent in selected refined mineral oil.The proportion of described refined mineral oil is 0.83～0.85, and its close flash point should be greater than 160 ℃, and the kinematic viscosity 40 ℃ the time is 8.0～9.0mm
2/ s, and its consumption is 94～96% of a composition gross weight; Described sanitas is dialkyl group (C
5～C
9) naphthalene sulfonate barium and/or barium mahogany sulfonate, its consumption is 1.8～2.2% of a composition gross weight, and described low friction compound is a sulfuration oleic acid, and its consumption is 1.5～2.5% of a composition gross weight; Described extreme pressure agent is the sulphur clorafin, and its consumption is 0.8～1.0% of a composition gross weight.
Lubricating composition of the present invention can be prepared by following technology: get the satisfactory refined mineral oil impouring of capacity in enamel reaction still, be heated to a little more than 100 ℃, add sanitas, low friction compound and extreme pressure agent successively, constantly stir simultaneously, get final product when waiting to obtain the homogeneous goods.Finished product has following performance: proportion 0.84～0.85, and close flash point 〉=165 ℃, kinematic viscosity 8.5～9.0 centistokes in the time of 40 ℃, oil film is critical.Load 〉=80kg, kinetic friction coefficient f≤0.05.In these performance perameters, close flash point and kinematic viscosity mainly are subjected to the influence of refined mineral oil consumption, when the mineral oil consumption be total amount 95% the time, the former is 165 ℃, and the latter is 8.9 centistokes; The oil film critical loading then mainly is subjected to the influence of extreme pressure agent consumption, and when the extreme pressure agent consumption was 0.8%, the PB value can reach 80kg.
Embodiment 1:
By following formulated composition-
Mineral oil 95%(weight, down together)
Sanitas (dinonyl naphthalene sulfonate barium) 2.2%
Low friction compound 1.8%
Extreme pressure agent 1%
Be used for light-duty piston of gasoline engine (material Al245Si) essence with resulting composition and cut and use lubricating and cooling agent, the Ra=0.68 of finished product～0.8 adheres to specification fully as a result.
When the sanitas that replaces with part or all of barium mahogany sulfonate in the present embodiment, and during all the other components unchanged, the composition that obtains also can obtain close effect.
As seen, the invention provides a kind of be suitable for especially high flash point, low viscosity extreme pressure property machining oil that nonferrous materials precision sizing such as wear-resistant aluminum alloy is used, economical and that be easy to get.
