Embodiment 1
[0007] A kind of automotive gear lubricating oil with strong oxidation resistance. The raw materials in the formula are composed by weight percentage: pure mineral oil 5%, polyether synthetic oil 1%, alkylbenzene oil 1%, biodegradable lipid oil 5% %, bio-based base oil 3%, synthetic lubricating oil 2%, oleamide 1%, extreme pressure anti-wear agent 11%, anti-oxidant anti-corrosion agent 5%, metal deactivator 3%, rust inhibitor 3%, anti-foam 1% additive, 5% oily agent, and 1% viscosity index improver. At this time, the automotive gear oil has strong extreme pressure and anti-wear properties, but poor oxidation resistance.
Embodiment 2
[0009] A kind of automotive gear lubricating oil with strong oxidation resistance. The raw materials in the formula are composed by weight percentage: pure mineral oil 15%, polyether synthetic oil 5%, alkylbenzene oil 10%, biodegradable lipid oil 15% %, bio-based base oil 9%, synthetic lubricating oil 3%, oleamide 5%, extreme pressure anti-wear agent 19%, antioxidant anti-corrosion agent 7%, metal deactivator 5%, rust inhibitor 5%, anti-foam 5% additive, 10% oily agent, and 1.5% viscosity index improver. At this time, the automotive gear oil has strong anti-oxidation performance, but its extreme pressure and anti-wear performance is poor.
Embodiment 3
[0011] A kind of automotive gear lubricating oil with strong oxidation resistance. The raw materials in the formula are composed by weight percentage: pure mineral oil 10%, polyether synthetic oil 3%, alkylbenzene oil 6%, biodegradable lipid oil 10% %, bio-based base oil 6%, synthetic lubricating oil 2.3%, oleamide 1.5%, extreme pressure anti-wear agent 11.9%, anti-oxidant corrosion inhibitor 5.7%, metal deactivator 3.5%, rust inhibitor 3.5%, anti-foam 1.5% additive, 8% oily agent, and 1.28% viscosity index improver. At this time, the automotive gear oil has strong extreme pressure and anti-wear properties, and has strong anti-oxidation properties.

Abstract
The invention relates to an automobile gear lubricant with strong oxidation resistance. According to a formula, the automobile gear lubricant is prepared from the following raw materials in percentageby weight: 5 to 15% of pure mineral oil, 1 to 5% of polyether synthetic oil, 1 to 10% of alkylbenzene oil, 5 to 15% of biodegradable lipid oil, 3 to 9% of biological-based base oil, 2 to 3% of synthetic lubricating oil, 1 to 5% of oleamide, 11 to 19% of an extreme-pressure antiwear additive, 5 to 7% of an antioxidantpreservative, 3 to 5% of a metal deactivator, 3 to 5% of an antirust agent, 1 to 5% of an antifoaming agent, 5 to 10% of an oiliness additive and 1 to 1.5% of a viscosity index improver. The automobile gear lubricant has the advantages of stronger extreme-pressure antiwear property and stronger oxidation resistance.
