Abstract

The invention relates to the field of lubricating oil, and discloses a saturated polyol-ester type high-temperature chain oil and a preparation method of the chain oil. The chain oil comprises the following components in percentage by mass: 1-8% of at least two antioxidants, 0.1-1% of at least one metal passivator, 0.1-5% of at least one extreme-pressure antiwear agent, 1-20% of at least one high-temperature detergent dispersant, 1-15% of at least one anti-dripping agent, and the balance of saturated polyol-ester base oil. According to the invention, saturated polyol ester is completely adopted as the base oil for preparing the high-temperature chain oil, so that the chain oil has the characteristics of low evaporation loss, small coking amount, good lubricity, dripping resistance, environment-friendly products and the like.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a saturated polyol ester type high-temperature chain oil and a preparation method thereof. Background technique [0002] Chain oil is widely used in heat-setting machines and stretching stenters in the textile and printing and dyeing industries, chain transmission systems in high-temperature ovens in the building materials industry, kiln wheel hub bearings in refractory factories, supporting rotor hubs in ovens in cement plants, and drying in spraying lines box etc. Due to the high service temperature of chain oil, chain oil must withstand harsh conditions, including the influence of humidity, dust and production conditions, outdoor climate conditions, high and low temperatures, impact loads, temperature changes, changes in surrounding media, exposure to water, etc. This requires: 1. The chain oil has good adhesion, and the chain oil with poor adhesion is easy to lose during use a...
