Abstract
The biodegradable lubricating oil for automobile engine includes modified vegetable oil, viscosity index improver and composite additive. The production process of the biodegradable lubricating oil includes preparing the composite additive via heating dibasic acid ester to 60 deg.c, adding antiwear agent, pour point reducer, antioxidant, antirust deactivator and light stabilizer via stirring, maintaining for 30 min and cooling to normal temperature; adding the composite additive and the viscosity index improver into vegetable oil via stirring; heating the mixture to 100-130 deg.c, maintaining for 30 min and cooling to normal temperature to obtain the product. The present invention can save petroleum resource and solve the pollution caused by waste lubricating oil.
Description
Affiliated technical field
The present invention relates to a kind of lubricating oil and preparation method thereof, is a kind of biodegradable lube oil that is used for motor car engine and preparation method thereof.
Background technology
At present, automobile oil is a base oil with mineral oil or synthetic oil all generally, after these lubricating oil are in a single day discarded, enter soil and can not degrade for a long time, can cause serious pollution to environment.Biodegradable lube oil adopts biodegradable renewable resources---and the vegetables oil that comprise one or more process modifications in castor oil, Oleum Gossypii semen, rapeseed oil, the soya-bean oil are base oil.The degradable characteristic that it has kept vegetables oil can satisfy the service requirements of motor car engine by the adjusting of other additive.
Summary of the invention
The objective of the invention is: in order to overcome with mineral oil or synthetic oil is the shortcoming that the lubricating oil of base oil is difficult to degrade, in the hope of finally improving their pollutions to environment.
The present invention solves the technical scheme that its technical problem takes: biodegradable lube oil comprises the vegetables oil through modification, viscosity index improver, composite additive.Its additive is characterised in that: add the diprotic acid diester to improve the property at high and low temperature of vegetables oil, it is general to make it the four seasons; Add the viscosity index improver contain ethylene-propylene copolymer etc., to improve viscosity characteristics; Interpolation is the metal rust preventing passivator of feature to contain sulfonate, alkylsalicylate, benzotriazole, dinonylnaphthalene sulfonic acid salt etc., and the cylinder body metal is protected; Interpolation is the pour point depressant of feature to contain polymethyl acrylic acid, alkylnaphthalene, poly-alpha olefins etc., to reduce freezing point and to improve low-temperature dynamic viscosity; Interpolation is to contain sulphur phosphorus secondary alcohol groups zinc salt, alkyl diphenyl amine antioxidants and photostabilizer, to improve the stability of long-acting use; Interpolation is to comprise the anti-wear agent that nano-scale carbon or silicon-dioxide are feature, to improve lubricating system and effect.At first produce composite additive during making, the diprotic acid diester is heated to 60 ℃ after, add anti-wear agent, pour point depressant, oxidation inhibitor, metal rust preventing passivator, photostabilizer and stir, be incubated 30 minutes, be cooled to normal temperature, must composite additive; Again viscosity index improver, composite additive are added in the vegetables oil, stir, be heated to 100～130 ℃, be incubated 30 minutes, be cooled to normal temperature, promptly get this product.
The invention has the beneficial effects as follows: biodegradable lube oil, adopt renewable resources---vegetables oil, realized biodegradable, not only saved the petroleum resources of worsening shortages, solved the serious pollution problem that waste lubrication oil brings.Solved the vegetables oil oxidation-resistance, temperature profile etc. have been explored nano material homodisperse in lubricating oil and have been reached problems such as effectively improving lubricity the detrimentally affect of lubricating oil quality.
