Water soluble full-alloy metal grinding fluid

The invention discloses a water soluble full-alloy metal grinding fluid which belongs to the technical field of metal grinding fluids. The metal grinding fluid is prepared from the following components in percentage by weight: 5-40wt% of an antirust agent, 1-20wt% of a cleaning agent, 0.1-10wt% of a lubricating corrosion inhibitor, 1-20wt% of a penetrant, 1-20wt% of a solubilizer, 10-40wt% of a PH adjustor, 0.5-5wt% of a defoamer and the balance of water. Based on the total weight of the water soluble full-alloy metal grinding fluid, the pH value of the water soluble full-alloy metal grinding fluid is 7-11. The lubricating corrosion inhibitor is long chain nitrogen heterocyclic ring organic ester. The water soluble full-alloy metal grinding fluid has excellent lubricating, rust-preventing, cleaning and cooling performances and can be widely applied to grinding of ferrous metals and nonferrous metals.
