Composite additive applied to engine oil

[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.
