Problems solved by technology

[0010] (5) Low temperature performance: In winter, when the equipment is shut down for a long time and restarted, if the viscosity of the chain oil is too high or solidified, it will cause difficulty in starting the equipment, prolong the warm-up time, and even burn the inverter or motor
[0012] Currently commercially available high-temperature chain oils suitable for industrial use are mainly mineral oil-based products. The working temperature of this type of product does not exceed 250°C, the coking cycle is short, and it is easy to be shut down during the operation process. The coking amount accumulates during the coking process It also causes cleaning problems, requiring frequent shutdowns for cleaning, which affects the use effect and service life of the equipment
Commercially available chain oil also suffers from high-temperature volatilization loss, which needs to be supplemented frequently, which affects economic benefits

Abstract

The invention relates to a high-temperature chain oil, which comprises the following components: PAO synthetic base oil, high-temperature antioxidant, low-temperature antioxidant, detergent, dispersant, friction modifier, extreme pressure anti-wear agent, and viscosity index improver , pour point depressant, rust inhibitor. The high-temperature chain oil provided by the above technical solution has outstanding high-temperature stability and long coking cycle; excellent low-temperature stability, keeping the transmission system working smoothly at low temperature, the working temperature is ‑40℃ to 350℃, suitable for severe high and low temperature Converting working conditions, at the same time, it has extremely low volatility and low consumption of chain oil, which is an economical and environmentally friendly product, suitable for industrial use.

Description

technical field [0001] The invention relates to the field of lubricating oils, in particular to a high-temperature chain oil. Background technique [0002] The chain is one of the mechanical transmission components. It is widely used in various industries due to its ability to accurately transmit power, stable transmission, constant speed ratio, strong adaptability, unaffected by size, and easy maintenance. Especially in today's highly automated production equipment, the chain has become one of the main transmission components of mechanical transmission. [0003] For chain drives, even if the chain and sprocket are designed to meet the conditions of use and the environment, if the lubrication is poor, it is impossible to give full play to the designed performance and guarantee the service life. The chain has good lubrication and poor lubrication in use, and its wear amount can vary by 200 to 300 times. Once the lubrication is insufficient, the pins and sleeves will wear out...
