High-temperature chain oil and preparation method thereof

Abstract

The present invention discloses high temperature chain oil, the components and the contents are: high temperature antioxygen 1 to 5 percent, extreme pressure/anti-wear agent 1 to 10 percent, corrosion inhibitor 0.01 to 0.5 percent, and high temperature detergent dispersant 1 to 20 percent, the rest is base oil; the components and the contents of the base oil (weight ratio) are: dipentaerythritol ester 50 to 90 percent, and aromatic ester 10 to 50 percent. The preparation is as follows: the dipentaerythritol ester and the aromatic ester are mixed together according to the above ratio to prepare the base oil, a certain volume of the high temperature antioxygen, the extreme pressure anti-wear agent, the high temperature detergent dispersant and the corrosion inhibitor is added into the base oil, then the base oil is heated to 80 to 100 DEG C, and is agitated at the constant temperature for 0.5 to 1 hour, and is filtrated, thus the product is got. The present invention is characterized in that the coking volume can be obviously reduced, the anti-high temperature coking performance and the high temperature detergency performance can be improved, the product can be used under the 280 DEG C high temperature condition, the evaporation loss is little, and the coking volume is little, the lubrication performance and the high temperature detergency and dispersing performance is good.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a high-temperature chain oil and a production method thereof. Background technique [0002] For drying rooms, ovens, furnaces, stretching stenters and other equipment used in textile, building materials, papermaking, plastic film and other industries, the performance requirements of the chain transmission and gear drive systems for lubricating oil are mainly reflected in: thermal oxidation performance, evaporation Loss, lubricating extreme pressure performance, adhesion and viscosity and viscosity index and so on. [0003] At present, the use temperature of mineral oil type or mineral oil / ester oil semi-synthetic chain oil is relatively low, generally below 150°C. Although polyether-type high-temperature chain oil has better high-temperature performance and does not coke at high temperatures, its high-temperature evaporation loss is too large. At higher operating temperatures, polyether-type...
