Abstract

The invention provides lubricating oil for engineering machinery and a preparation method thereof. The lubricating oil is prepared from the following components: modified calcium carbonate, modified titanium dioxide, modified nano copper powder, an ethanol solution, linseed oil, polyurethane, a natural gum extract, paraffin, basic oil, a dispersing agent, a viscosity index improver, an antioxidant, polyalcohol, a defoaming agent, an extreme pressure antiwear agent and an oiliness agent. The lubricating oil prepared by the preparation method provided by the invention can substantially reduce the friction power consumption and wear of the engineering machinery and heavy machinery equipment; meanwhile, the working temperature rise of the equipment is obviously reduced; pollution of waste andleaking engine oil to the environment is relieved; the consumption of the lubricating oil is reduced; nonrenewable petroleum resources are saved.
