Description

A kind of lubricant oil composite of energy-saving and emission-reduction
Technical field
The present invention relates to lubricant, it is related specifically to a kind of lubricant oil composite of energy-saving and emission-reduction.
Background technology
At present, because the poly- increasing of consumption gathered around by automobile, improve work efficiency and living standard, but its energy resource consumption and tail gas Discharge is also very surprising to the pollution of environment.In order to response environment problem such as reduces CO2 emission, in automobile and building Build or agricultural machinery in energy saving, that is, saving fuel has become in the urgent need to and electromotor, variator, final transmission subtract The device of fast machine, compressor or oil hydraulic power device needs energy-conservation strongly.Therefore, used in these systems, lubricating oil needs to compare More reduced stirring resistance and frictional resistance in the past.
Improved by lubricant formula technology fuel-economy cost be far below additive method as change electromotor design, Improve fuel qualities etc., therefore, energy-saving Lubricating Oil Technique is increasingly taken seriously.Improve fuel oil using THE ENERGY CONSERVATION TECHNOLOGY OF LUBRICANT Economy mainly has two approach, and one is suitably to reduce oil viscosity, and two is to be reduced between parts using organic friction modifiers Frictional dissipation.Under fluid lubrication and elastohydrodynamic behaviour state, reduce oil product viscosity rank and can reduce hydrodynamics resistance Power, reducing energy consumption, but should be noted the durability of electromotor.Under boundary lubrication and mixed lubricating state, add organic anti-friction agent Boundary friction loss can effectively be reduced, but should be noted the holding to raising fuel economy in oil product use for the friction improver Property.
However, the oil body reducing for these variators may cause said apparatus and its mechanism's fatigue life Serious curtailment and may produce occlusion, lead to some faults in variator.Especially when by low-viscosity oil with Phosphorus When extreme pressure additive blending is to strengthen extreme pressure property, by serious curtailment fatigue life.Therefore it is generally difficult to reduce the viscous of lubricating oil Degree.Although sulfur class extreme pressure additive can improve fatigue life, deterioration oil ageing stability simultaneously therefore must be blended A large amount of antioxidants.
The Chinese invention patent application of Publication No. cn10351576a, cn103497815a and cn103923728a is respectively Disclosing antiwear and energy-saving lubricant oil, in above-mentioned application, all coefficient of friction being reduced thus reaching using the oil-soluble organic-molybdenum salt of addition To the purpose of energy-conservation, have a disadvantage in that: organic-molybdenum salt adsorbs in gold after only generating antifriction material after high temperature occurs chemical reaction Metal surface, thus producing friction reducing effect, in low temperature, antifriction ability is weaker, and the prolongation with oil product use time, organic-molybdenum The peroxide being produced with oil oxidation is reacted, and effective molybdenum content can be led to be gradually reduced, and frictional resistance increases, and fuel oil disappears Consumption increases on the contrary.
Publication No. cn101481638a Chinese invention patent application proposes a kind of energy-saving and emission-reducing heavy truck special-purpose nanometer Wearproof lubricant and preparation method thereof, this patent is mainly for heavy load Diesel engine, and the viscosity of oil product is higher, is starting Machine friction part is in can increase fuel consumption during Liquid Lubrication Condition on the contrary, do not possess synthesis energy saving effect.
Content of the invention
It is contemplated that in solve the deficiencies in the prior art, have developed a kind of lubricant oil composite of energy-saving and emission-reduction it is ensured that There is within the whole drain period lasting effects of energy conservation and environmental protection.
The present invention solves a kind of technical problem: lubricant oil composite of energy-saving and emission-reduction by the following technical programs, containing with The component of lower percentage by weight: mass percent be 80 90% base oil and mass percent be 10 20% additive, Described additive includes viscosity index improver, pour-point depressant, extreme pressure agent, detersive, antioxygen anti-corruption antirust agent, antifriction antiwear are worked in coordination with Agent, anti-foaming agent.
Described base oil is the mixing of poly alpha olefin synthetic base oil and Esters oil, and both mass ratioes are 3:1- 1:3.
Described pour-point depressant be poly-alpha olefins or polymethyl methacrylate, its content be account for composition quality percentage ratio 0.05～ 5%.
Described detersive is sulfoacid calcium or salicylic calcium, and its content accounts for the 0.2～5% of composition quality percentage ratio.
Described extreme pressure agent is boric acid fatty ester amine salt, and its content accounts for the 0.02～0.5% of composition quality percentage ratio (with boron Weight meter).
Described viscosity index improver is polyvinyl n-butyl ether, polymethacrylates, polyisobutylene, polyacrylic acid Any one or more in ester, succimide ethylene-propylene copolymer and styrene-diene copolymer, its content is to account for combination material The 0.05～5% of amount percentage ratio.
Described antioxidant preservative is sulfur phosphorus alkyl phenol zinc salt, sulfur phosphorus fourth octyl group zinc salt, the double octyl group basic zinc salt of sulfur phosphorus and sulfur Any one or more in phosphorus dialkyl group zinc salt, its content is account for composition quality percentage ratio 0.05～5%；
Described anti-foaming agent is arbitrary in dimethicone, acrylate and vinyl ether co-polymer and castor oil polyoxyethylene ether Plant or multiple, its content is account for composition quality percentage ratio 0.05～5%.
Described antifriction antiwear synergist be benzotriazole lauryl amine salt, its content be account for composition quality percentage ratio 0.05～ 5%.
By the compatibility of said components, oil product is made to have the advantage that
The lube base oil of the present invention is a certain amount of poly alpha olefin synthetic base oil and Esters oil synthetic base oil so that oil There is during product high temperature good viscosity holding capacity and outstanding lubricity, occur synergism to improve antifriction with friction improver Effect, and with friction modifiers, competitive Adsorption will not occur and affect the performance of friction improver effect, and to engine interior Carbon distribution has certain cleaning action.And in conventional lubrication oil, adopt highly polar Esters oil such as trihydroxymethylpropanyl ester etc. more, The performance of friction improver effect can be had a negative impact in high temperature.
Add detersive to be sulfoacid calcium or salicylic calcium in lubricant oil composite of the present invention, the clear of engine interior can be improved Net property, reduces the carbon distribution because oil oxidation produces or paint film is attached to the frictional dissipation that inside leads to, and improves the fuel oil warp of oil product Ji property holding capacity.
The regeneration capacity of lubricant oil composite of the present invention, anti-caking power are much higher than traditional lubricating oil, can to equipment To provide more preferable anti-wear protection.
In sum, a kind of coefficient of friction of the lubricant oil composite of energy-saving and emission-reduction of the present invention is low, antifriction potentiation is worked in coordination with Effect is high, has significantly energy-conservation and emission reduction effect.
