The invention provides anti-burning hydraulic fluid, which is characterized by the composition of diethylene glycol, polyether, lubricant, corrosion inhibitor, foam inhibitor, defoamer and water; wherein, the invention comprises 35 portions to 55 portions of diethylene glycol, 10 portions to 19 portions of polyether, 0.9 portions to 3.6 portions of lubricant, 3 portions to 4.5 portions of corrosion inhibitor, 0.4 portions to 0.8 portions of foam inhibitor, 0.02 portions to 0.04 portions of defoamer, and 35 portions to 55 portions of deionized water. The invention has excellent flammability resistance, lubrication, extreme-pressure abrasion resistance and defoaming performance. The invention can be widely used in such industries as metallurgy, coal, chemical, machinery, casting and other industries. The use of the foam inhibitor and defoamer can make the height of foam below 25cm and the defoaming time less than 15 seconds. The invention eliminates the influence of foam on the whole hydraulic system; the measurement according to the NAS 1638 standard has proven that the cleanliness standard has achieved the sixth grade.
