Problems solved by technology

Traditional industrial gear oil generally chooses mineral oil as the base oil. The naphthenes, paraffins, aromatics and other compounds in mineral oil are harmful to the environment. During use, they will seriously pollute rivers and lakes on land due to leakage and splashing. Poor biodegradability, accumulation in the environment will affect the ecological environment and ecological balance

Abstract

The invention relates to a biodegradable industrial gear oil composition which is composed of at least one extreme pressure wear-resistant agent (a), at least one antioxidant (b), at least one friction improver (c), at least one demulsifying agent (d), at least one antirust agent (e), at least one anti-foaming agent (f) and at least one synthesis base oil (g). Biodegradable industrial gear oil has outstanding biodegradable performance, outstanding extreme pressure wear-resistant performance, excellent sealing material compatibility, excellent emulsion resistance, good oxidation stability and good corrosion resistant performance. The composition can be used for lubricating various gear devices comprising spur gears, helical gears, bevel gears and the like in environmentally sensitive areas, and can completely meet the requirement of environmental protection for the biodegradable performance of oil products.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition with outstanding biodegradable performance, extreme pressure and anti-wear performance, excellent sealing material compatibility, excellent anti-emulsification performance, good oxidation stability and anti-corrosion performance of biodegradable industrial gear oils. Background technique [0002] Gear mechanism is an important transmission mechanism of mechanical transmission, which has a large transmission power range and high transmission efficiency, and can transmit motion and power between any two axes. The transmission of motion and power is accomplished in the interaction and relative motion of each pair of meshing tooth surfaces in the gear mechanism, during which friction must be generated. In order to avoid the direct friction of the parts between the working surfaces of the gears, lubricants are needed to separate the working surfaces to en...
