Description
技术领域
本发明涉及液压液技术领域，尤其涉及一种润滑抗燃液压液及其制备方法。
背景技术
水-乙二醇型抗燃液压液无闪点、无燃点，具有优异的不燃性，同时又具有抗腐蚀、抗泡、防锈以及良好的低温性能，目前被广泛应用于苛刻工况下的连铸生产线液压系统、高炉液压系统、拆炉机液压系统、热轧厂液压系统、铸造厂液压系统、电站液压系统和煤矿液压系统。
受基础组分的限制，水-乙二醇型抗燃液压液形成的油膜强度较弱，不能在金属表面生成牢固的极压润滑膜，对运动摩擦副的润滑性能稍差，对液压设备的润滑保护相对有限。具体为：现有的水-乙二醇型抗燃液压液四球试验机最大无卡咬负荷(PB)为588N，低于相同黏度等级下矿物油的PB为834N和合成酯抗燃液压油的PB为883N。
