Abstract

The invention relates to water-based fire-resistant hydraulic oil which is composed of the raw materials of, by mass, 35-54% of water, 35-54% of ethylene glycol, 8-10% of a thickening agent, 0.5-1% of an anti-wear agent, 0.05-0.1% of a defoaming agent, 0.05-0.1% of a preservative, 1-5% of an anti-rust agent, 0.1-0.5% of a metal passivator, and 1-2% of a detergent dispersant. The water-based fire-resistant hydraulic oil provided by the invention has excellent fire resistance, defoaming performance, lubricating performance, and anti-rust performance. The water-based fire-resistant hydraulic oil has wide application scope.

Description

technical field [0001] The invention relates to the field of hydraulic oil, in particular to a water-based fire-resistant hydraulic oil. Background technique [0002] In the field of hydraulic oil production, due to the lack of performance and sources of mineral oil base oils, non-petroleum hydraulic oils have been more widely and deeply used. The non-petroleum hydraulic oils in the prior art are mainly produced in water or Various additives are added to other base fluids (including emulsified fluids or synthetic fluids, such as high-water base fluids, water-glycol fluids, phosphate ester fluids, etc.) to make them more suitable for traditional hydraulic systems. Currently, the most widely used Fire-resistant hydraulic oil is a water-glycol liquid, but it has problems such as corrosion of metals, poor lubricity, flame resistance and wear resistance, and long defoaming time during use, which limits the use of fire-resistant hydraulic oil to a certain extent. scope of applica...
