Novel synthetic fire-resistant hydraulic oil composition

Abstract

The invention relates to a novel synthetic fire-resistant hydraulic oil composition. The composition is characterized in that the fire-resistant hydraulic oil composition is prepared by using low-viscosity ester oil as basic oil, little synthetic hydrocarbon component as a solubilizer and high-viscosity ester oil as a tackifier, and adding proper functional additives. The composition has lower volatility, excellent lubricating property, high and low temperature stability, wider using temperature range, excellent flame resistance, biodegradability, long service life and other excellent performance. The composition comprises the following components in percentage by weight: 40 to 70 percent of the low-viscosity ester oil, 10 to 20 percent of the synthetic hydrocarbon component, 0 to 10 percent of the high-viscosity ester oil, 2 to 10 percent of composite additive, and 10 to 200ppm of anti-foaming agent. The composition is mainly applied to steel continuous casting production line systems and hydraulic systems of blast furnaces, hot rolling, casting, power stations, coal mines and the like which require flame resistance and safe equipment.

Description

A Novel Synthetic Fire-resistant Hydraulic Oil Composition technical field The present invention relates to a lubricating oil composition, in particular to a hydraulic system mainly used in steel continuous casting production line systems and blast furnaces, hot rolling, casting, power stations, coal mines and other equipment requiring fire resistance and safety Synthetic fire resistant hydraulic oil. technical background The development of fire-resistant hydraulic oil began in World War II. First, the use of phosphate ester fire-resistant hydraulic oil in aircraft systems, followed by emulsified oil, water-glycol fire-resistant hydraulic oil, phosphate ester type Fire-resistant hydraulic oil, chlorinated hydrocarbon hydraulic oil, etc., and gradually extended to civilian industry. With the continuous development of modern hydraulic technology, the working conditions of equipment are becoming more and more stringent, and the requirements for fire protection and environmen...

Problems solved by technology

In recent years, synthetic ester fire-resistant hydraulic oil has been developed rapidly, but domestically-produced ester-type fire-resistant hydraulic oil, in order to achieve high lubricity and good anti-oxidation performance, the addition of additives is often very high, so It will cause the disadvantages of large ash content, low degradation rate, and many residues of the oil.
