Abstract
The invention relates to antiwear lubricating oil prepared by mixing, heating, stirring and filtering 3%-6% of antiwear additive, 1%-2.5% of dispersant, 0.5%-1% of detergent, 0.5%-1% of pour point depressant, 0.5%-1% of anti-corrosion antioxygen, 2%-4% of viscosity index improver and the balance of base oil, wherein the antiwear additive is nanoscale metal powder and comprises ferric oxide powder,copper powder, chromium powder, manganese powder and boron powder; the dispersant is polyisobutene-multi-succinimide; the detergent is calcium mahogany sulfonate or sulfurized calcium alkyl phenolate; the pour point depressant is polymethylacrylic acid ester; the anti-corrosion antioxygen is butyl-octyl zinc thiophosphate; and the viscosity index improver is ethylene-propylene copolymer. A preparation method is simple and practical; in addition, the prepared lubricating oil has low cost, obvious antiwear and wear-reducing effects, repairing function, no corrosion effect inside a machine.
Description
(1) technical field
The present invention relates to a kind of lubricating oil, particularly a kind of abrasion-proof lubricant oil and manufacture method thereof.
(2) background technology
Development along with engine technology, performance to cylinder oil, have higher requirement, and lubricating oil additive is depended in the raising of lubricating oil quality mostly, promptly in lubricating oil processing, often need to improve the performance and the quality of lubricating oil by the method that adds additive, in order to increase the anti-wear effect of lubricating oil, often need in lubricating oil, add additive for wear resistance of lubricating oil, the wear preventive additive that adds in lubricating oil at present all has certain anti-wear effect, but result of use is undesirable, and life-time service can make carbonizing of engine increase, even loses lubricating oil, and makes engine corrosion impaired; The wear-resistant preferably agent price of adding of anti-wear effect is relatively more expensive again.
(3) summary of the invention
The purpose of content of the present invention provides a kind of engine is had significantly wear-resistant, repairing effect at the problem that exists in the above-mentioned technology, and mechanical inside is not had corrosive nature, does not lose lubricating oil, wearproof lubricant that cost is low and manufacture method thereof.
Technical scheme of the present invention:
A kind of abrasion-proof lubricant oil is characterized in that: be made up of base oil, wear preventive additive, purification agent, pour point depressant, anti-rotten oxidation inhibitor and viscosity index improver; Wear preventive additive is a nanometre metal powder, comprises brown iron oxide, copper powder, chromium powder, manganese powder and boron powder; Dispersion agent is many butyryl of polyisobutene imines; Purification agent is calcium mahogany sulfonate or alkyl monosulfide powder calcium; Pour point depressant is a polymethacrylate; Anti-rotten oxidation inhibitor is sulphur phosphorus Ding Xinjixin salt; Viscosity index improver is an ethylene propylene copolymer; The weight percent of various components is wear preventive additive 3-6%, dispersion agent 1-2.5%, purification agent 0.5-1%, pour point depressant 0.5-1%, anti-rotten oxidation inhibitor 0.5-1%, viscosity index improver 2-4%, and surplus is a base oil.
A kind of above-mentioned abrasion-proof lubricant oil, it is characterized in that: base oil is to subtract any two kinds of components of four lines, 10 centistokes, 5 centistokes, HVI500, HVI150,150BS, 46#, 68#, base oil or the combination of three kinds of components, and the weight quota ratio of each component is 1: 1 or 1: 1: 1.
A kind of above-mentioned abrasion-proof lubricant oil is characterized in that: the weight quota of each component is than being brown iron oxide 1, copper powder 1.5, chromium powder 1, manganese powder 1, boron powder 1.5 in the wear preventive additive.
A kind of manufacture method of above-mentioned abrasion-proof lubricant oil, base is characterised in that base oil, wear preventive additive, dispersion agent, purification agent, pour point depressant, anti-rotten oxidation inhibitor and viscosity index improver is mixed, heat and controlled temperature in 45-55 ℃, stirred 120-150 minute, promptly get product after the filtration.
Advantage of the present invention: this method is simple and practical, and the lubricating oil cost that makes is low, and engine is had significantly wear-resistant and antifriction effect, the excellent repairing function, and mechanical inside all do not had corrosive nature.
