Problems solved by technology

Although improving the demulsification performance can temporarily solve the impact of water on the lubricating oil, the additives in the lubricating oil are often gradually reduced with the separation of water
The existence of a small amount of water is still easy to cause lubrication failure
Direct replacement of gear oil increases the cost of use of the enterprise

Abstract

The invention discloses improved anti-compression lubricating oil which is prepared by the following raw materials by weight: 2.2-3.5 parts of silicon oxide particles, 1.3-3.7 parts of modified polysiloxane, 2.5-4.6 parts of pyridine sodium sulfate, 33-56 parts of industrial white oil, 1.6-4.6 parts of methyl phenol polyoxypropylene ether, and 2.4-7.6 parts of chlorinated paraffin. The lubricating oil composition of the invention has excellent viscosity-temperature property and a high viscosity index; when used in a wide temperature range, the oil product still has proper viscosity and oil film thickness; the oil product has good fluidity at low temperature, which facilitates pumping or carrying to lubrication points, guarantees the safety indexes for the application of the oil product, and facilitates the transport, storage and application of the oil product. Synthetic gear oil provided in the invention has good lubricity when mixed with 20% water.

Description

technical field [0001] The invention relates to an improved anti-pressure lubricating oil, which belongs to the field of industrial chemical industry. Background technique [0002] Lubricating oil is an important lubricating oil prepared mainly from mineral base oil or synthetic base oil, adding extreme pressure anti-wear agent and oily agent. It is used in various gear transmission devices to prevent tooth surface wear and abrasion , sintering, etc., to prolong its service life, improve the efficiency of power transmission, and reduce power loss. Lubricating oil should have good anti-wear, load-resistant performance and suitable viscosity. In addition, it should also have good thermo-oxidative stability, anti-foaming properties, water separation performance and anti-rust performance. Even under high operating temperature and load, the synthetic gear oil can still ensure that the various parts of the transmission system are not worn. In industrial production, cooling water...
