Synthetic fire-resistant hydraulic oil

The invention discloses synthetic fire-resistant hydraulic oil and belongs to the technical field of hydraulic oil. The synthetic fire-resistant hydraulic oil is prepared from components in percentageby mass as follows: 95%-98% of base oil, 0.4%-1.0% of an antioxidant, 0.03%-0.15% of an oiliness agent, 0.5%-3.0% of a tackifier, 0.4%-1.2% of an anti-wear reagent at extreme pressure, 0.1%-0.3% of an antirust agent, 0.02%-0.06% of an anti-emulsifying agent, 0.02%-0.04% of a metal deactivator and 0.01%-0.06% of a defoaming agent. The synthetic fire-resistant hydraulic oil not only has good high-temperature oxidation stability and flash point, has excellent pour point and can be normally used in the cold region, and besides, the product further has excellent anti-wear property. 本发明公开种合成抗燃液压油，属于液压油技术领域，按质量百分比计由下述组分组成：合成基础油为95-98％、抗氧剂为0.4-1.0％、油性剂为0.03-0.15％、增粘剂0.5-3.0％、极压抗磨剂为0.4-1.2％、防锈剂为0.1-0.3％、抗乳剂为0.02-0.06％、金属钝化剂为0.02-0.04％、消泡剂为0.01-0.06％。本发明合成抗燃液压不但具有良好的高温氧化稳定性能和闪点，还具有优秀的倾点，可在寒冷地区正常使用，另外该产品还具备了优良的抗磨性能。
