Biodegradable industrial gear oil and preparation method thereof
An industrial gear oil and biodegradation technology, applied in the field of lubricating oil, can solve the problems of not being able to adapt to various working environments, having no working indicators, and poor degradation performance, achieving good oxidation stability, ensuring environmental friendliness, and good The effect of biodegradation rate
Examples
Embodiment 1
[0019] Embodiment 1, the raw materials of the biodegradable industrial gear oil include 0.8% to 2.0% of extreme pressure antiwear agent, 0.1% to 0.5% of phosphorus antiwear agent, 0.03% to 0.10% of metal deactivator, 0.1% to 0.5% of anti-oxidant and anti-corrosion agent, 0.03% to 0.10% of anti-rust agent and the balance of base oil. The indicators of copper sheet corrosion, anti-corrosion, oxidation stability and biodegradation rate of the biodegradable industrial gear oil prepared according to the embodiment of the present invention are shown in Table 1.
