Abstract

The invention relates to a composite additive applied to engine oil. The composite additive is composed of base oil, an antioxidant, a dispersant, a cleaning agent, a corrosion inhibitor, a foaming inhibitor, a metal passivator, a demulsifying agent, a viscosity index improver, an extreme pressure additive, tungsten oxide powder, and molybdenum oxide powder. The composite additive has the advantage of simple production method, waste oil is biodegradable, an environmental protection requirement is completely reached, the usage period of a product is longer, antiwear and anti-extreme pressure efficacies of lubricating oil are improved; a plurality of efficacies of oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil are increased simultaneously, a cleanliness efficacy of the lubricating oil can be maintained for a long term, and the comprehensive efficacy of the lubricating oil of an engine can be completely enhanced.

Example Embodiment

[0011] Example 1
[0012] A composite additive used in engine oil, consisting of base oil; antioxidant; dispersant; detergent; corrosion inhibitor; foam inhibitor; metal deactivator; demulsifier; viscosity index improver; extreme pressure additive; oxidation Tungsten powder; molybdenum oxide powder. The base oil is composed of three components of synthetic base oil, poly-a-olefin, polyether and polyol ester; the weight ratio of the three components is 1:1:1. Antioxidant is a mixture of sterically hindered phenol and arylamine; dispersant is monobutyrimide; detergent is sulfurized calcium alkylphenate; corrosion inhibitor is substituted imidazoline; foam inhibitor is polyacrylate; metal reduction The active agent is benzotriazole; the demulsifier is polyalkoxy polyol; the viscosity index improver is styrene diene copolymer; the extreme pressure additive is alkyl phosphate ester and salt; tungsten oxide powder and molybdenum oxide powder It is a nanometer powder with a particle size of 25-35nm. The weight percentage of each component is: base oil 54%; antioxidant 10%; dispersant 4%; detergent 6%; rust inhibitor 6%; foam inhibitor 2%; metal deactivator 5%; demulsification Agent 3%; viscosity index improver 2%; extreme pressure additive 6%; tungsten oxide powder 1%; molybdenum oxide powder 1%. The above-mentioned base oil; antioxidant; dispersant; detergent; rust inhibitor; foam inhibitor; metal deactivator; demulsifier; viscosity index improver; extreme pressure additive; tungsten oxide powder; molybdenum oxide powder; Each component should be measured by weight percentage, then mixed uniformly, heated and controlled between 55-70℃, and stirred for 120 minutes. After filtering, the product of the present invention is produced.
[0013] This product was added to ordinary engine oil at a dosage of 4%. Through practical application and comparative testing, the following conclusions were drawn:
[0014] 1. Use the lubricating oil anti-wear and extreme pressure testing machine to do comparative experiments, and the anti-wear effect is increased by more than 1.2 times.
[0015] 2. Use the lubricating oil anti-wear and extreme pressure testing machine to do comparative experiments, and the anti-extreme pressure effect is increased by more than 1.5 times.
[0016] 3. Using a lubricating oil anti-wear and extreme pressure testing machine for comparison experiments, the diameter of long wear scars is reduced by more than 1.7 times.
[0017] 4. The antioxidant capacity is increased by more than 1.2 times.
[0018] 5. The cleansing and dispersion function is increased by more than 1.5 times.
[0019] 6. The indexes of anti-oxidation and anti-foaming are increased by more than 55%.
[0020] 7. Extend the oil change interval more than 2 times.
