Lubricant

The invention discloses a lubricant. The lubricant comprises the following ingredients: 150 parts of base oil, 13 parts of triethanolamine oleate, 4 parts of benzotriazole, 7 parts of ethylene oxide,3 parts of monopotassium phosphate, 2 parts of petroleum sodium sulfonate, 3 parts of sodium sulfite, 4 parts of sodium dodecyl benzene sulfonate, 4 parts of polyoxyethylene ether, 6 parts of trichloromethane, 6 parts of zinc sulfate, 5 parts of calcium carbonate, 6 parts of chlorinated paraffin, 7 parts of stearic acid and 6 parts of methylsalicylic acid. The lubricant can be still well adhered onto a cutting edge of a universal cutter at the high temperature of 800 DEG C, and can normally cut a high-hardness material, so that the service life of the cutter is prolonged. As the ingredients ofthe lubricant are common raw materials, the preparation is convenient. 本发明公开了种润滑油，基础油150份、油酸三乙醇胺13份、苯并三氮唑4份、环氧乙烷7份、磷酸二氢钾3份、石油磺酸钠2份、亚硫酸钠3份、十二烷基苯磺酸钠4份、聚氧乙烯醚4份，三氯甲烷6份，硫酸锌6份，碳酸钙5份，氯化石蜡6份，硬脂酸7份，甲基水杨酸6份。本发明的润滑油在800度的高温下仍然能够很好地附着在普通
