High-temperature chain oil composition of mixed base oil

Abstract

The invention relates to high-temperature chain oil of mixed base oil, which comprises: (1) 50-80 percent of ester oil; (2) 20-50 percent of specific polyether base oil; and (3) 1.5-3.5 percent of antioxidant, 0-3 percent of antiwear agent and 0-1 percent of rust inhibitor. The viscosity of the high-temperature chain oil at 40 DEG C is 150-320cst. Therefore, the high-temperature chain oil of the invention has a high viscosity index and low coking tendency under high temperature conditions.

Description

technical field The invention relates to a lubricating oil, in particular to a composition for lubricating high-temperature conveying chains. technical background Chain drive is not only suitable for use under high torque and low speed, but also shows superiority in corrosive and humid environments, as well as in high-speed transmission. The smooth operation of the chain, the flexibility of the chain links, and the reduction of wear depend on the good lubrication effect of the chain lubrication system. The chain lubrication system must regularly and quantitatively inject high-temperature lubricating oil into the gap between the pin shaft and the sleeve of the chain To ensure good lubrication and normal operation of the chain. With the rapid development of my country's textile, printing and dyeing, petrochemical, building materials and transportation industries, the operating temperature of the transmission system of these equipment is getting higher and higher, and the requ...

Problems solved by technology

However, due to the relatively low flash point of polyether, the volatile amount is relatively large under high temperature conditions.
