Abstract

The invention provides a special lubricating oil composition for a circulatory system of a paper machine. The composition comprises: (A) at least one deeply refined mineral oil with high viscosity index or synthetic oil, or arbitrary composition of the above components; (B) at least one sulfurous extreme pressure additive; (C) at least one phosphorus anti-wear additive; (D) at least one emulsifying additive; (E) at least one antifoam additive; (F) at least one metal passivator; (G) at least one antioxidant; and (H) at least one metal detergent. The above lubricating oil composition can meet the requirements of N100, 150, 220 and 320 viscosity grades, has excellent extreme pressure abrasion resistance, filterability, emulsification resistance, foaming resistance, air release property, thermal oxidation stability, rust and corrosion resistance and high temperature detergency, and is applicable to lubrication of the circulatory system of the paper machine.

Description

(1) Technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition used in a circulation system of a paper machine, and belongs to the technical field of lubricating oil and lubricating oil additives. (2) Background technology [0002] Special oil for paper machine circulation system (referred to as PMO) is a new type of oil that emerges as the paper industry develops towards high speed and large scale. With the development of paper machine equipment, the design of paper machine is more and more high-speed and wide. The working conditions of the paper machine circulation system are high temperature, certain load, and possible contact with water. Compared with the general hydraulic system and gear transmission system lubrication, the performance requirements of the oil are higher. The circulation system of papermaking equipment has the following characteristics: (1) Because the large paper machine is in continuou...
