The invention relates to an anti-wear lubricating oil composite agent, which is characterized by comprising base oil, an antioxidant, a cleaning agent, a dispersant, an extreme pressure anti-wear agent, a rust corrosion inhibitor, a pour point depressant, a metal deactivator, nanometer zinc, and tungsten disulfide, wherein the antioxidant is glycerol monooleate, the cleaning agent is a sulfated polyisobutylene salt, the dispersant is a styrene ester derivative, the extreme pressure anti-wear agent is vulcanized isobutylene, the rust corrosion inhibitor is synthetic sodium sulfonate, the pour point depressant is alkyl naphthalene, and the metal deactivator is benzotriazole. According to the present invention, the manufacturing method is simple; and the prepared product has characteristics of low price, high efficiency, high performance price ratio, complete providing of the comprehensive effect of the lubricating oil, strong repair on the aging wear of the mechanical equipment, improvement of the oxidation resistance and the corrosion resistance of the lubricating oil, cleaning effect, dispersing effect, simultaneous improvement of the wear resistance and the extreme pressure resistance, noise reducing, tail gas emission reducing, oil change period prolonging, fuel oil saving, and complete improvement of the comprehensive effect of the lubricating oil.

The invention provides fully-effective lubricating oil applied to engines. The lubricating oil is characterized by consisting of base oil, base liquid, liquid vitamin E, a rhenium-tungsten alloy, an antioxidant, a cleaning agent, a dispersant, a corrosion inhibitor, an anti-forming agent, a metal passivator, a demulsifying agent, an antiwear agent, an anti-extreme pressure agent, and a viscosity index improver. The lubricating oil provided by the invention has a simple manufacturing scheme, the price of a prepared product is lower than prices of other products of the same kind, the lubricating oil has high quality, and each performance requirement of the lubricating oil is comprehensively and effectively improved. The effects of resisting abrasion and extreme pressure of the lubricating oil can be improved to the maximum extent while the performances of the lubricating oil such as oxidation resistance, corrosion resistance, lustration decentralization, anti-foaming property, antirust property, and greasy filth generation prevention are comprehensively improved. The lubricating oil has the advantages of a prolonged service cycle, reduced noise of mechanical equipment, reduced energy consumption, and reduced tail gas discharge, and completely exceeds environmental protection requirements of present products of the same kind.

The invention discloses a lubricating oil anti-wear agent. The lubricating oil anti-wear agent comprises 65-80% by mass of base oil, 2-5% by mass of a rare earth compound, 2-5% by mass of liquid sodium polyacrylate, 5-10% by mass of an antioxidant, and 10-20% by mass of a dispersant. The lubricating oil anti-wear agent uses the unique chemical and physical performances of the rare earth compound, so the wear and extreme pressure resistances of oil are greatly improved; ionic bond exchange between sodium polyacrylate contained in the lubricating oil anti-wear agent and the surface of a metal facility is carried out, so a magnetic suspension effect is generated, and the part wearing is reduced; and no corrosive substances comprising sulfur or phosphorus are contained, so the lubricating oil anti-wear agent has no damages to parts, and does not cause environmental pollution.

The invention discloses anti-wearing extreme-pressure-resistant engine lubricating oil which consists of base oil, an antioxidant, a detergent, a dispersing agent, an extreme-pressure anti-wearing agent, a viscosity index improver, a nano-grade rhenium-molybdenum alloy powder material, polyacrylate, an ethyoxyl phenol, benzotriazole and vulcanized dipolybutylene, wherein the antioxidant is an thioether liquid of shielding phenol; the detergent is sulfurized alkyl phenate; the dispersing agent is a styrene ester derivative; the extreme-pressure anti-wearing agent is a composite ester of a high molecular weight; the viscosity index improver is a styrene diene copolymer. The anti-wearing extreme-pressure-resistant engine lubricating oil has the advantages of being scientific in preparation scheme and simple in preparation method, the price of a prepared product is lower than that of a similar product, various property requirements of the anti-wearing extreme-pressure-resistant engine lubricating oil can be effectively and comprehensively improved, the oxidation resistance, the corrosion resistance, the detergence and dispersity, the anti-rusting property, the bubble resistance and the greasy sludge prevention property of the anti-wearing extreme-pressure-resistant engine lubricating oil can be comprehensively improved, the effects of wearing resistance and extreme pressure resistance can be improved to the maximum extent, meanwhile a very good remediation function on a wearing surface of an engine can be achieved, the lubricating oil change period can be prolonged, the noise can be reduced, and the exhaust gas emission can be reduced.
