Abstract

The invention relates to the technical field of cutting fluids for metals, especially to an environmental-friendly water-based cutting fluid. The environmental-friendly water-based cutting fluid comprises a water-based basic solution, a cleaning agent, an oiliness agent, an antirust agent, a dimeric acid rare earth compound, a copper alloy corrosion inhibitor, an anticorrosive agent, a defoaming agent, an aluminum alloy corrosion inhibitor and a stabilizing agent of the aluminum alloy corrosion inhibitor. The cutting fluid provided by the invention has good versatility, is applicable to a plurality of metals and processing of aluminum alloy parts, exerts an excellent corrosion resistance effect on a copper alloy and an aluminum alloy and can effectively prevent the color of a sensitive aluminum alloy from changing; the cutting fluid has an excellent lubricating property, thereby ensuring processing precision and the service life of a cutter; the cutting fluid has an excellent antirust property, thereby preventing a workpiece and expensive machine tool equipment from rusting; the cutting fluid has protruding anticorrosion capability and hard water resistance; and the cutting fluid can be cyclically used for a long time, does not contain poisonous and harmful substances like nitrous acid, is beneficial for the environment and health, has good liquid waste disposal performance and can be treated as common industrial waste water.

Description

technical field [0001] The invention relates to the technical field of metal cutting fluids, in particular to an environmentally friendly water-based cutting fluid. Background technique [0002] Cutting (including grinding) is a processing method that uses a tool or grinding wheel to cut off a layer of allowance on the surface of the workpiece so that the workpiece can achieve the required dimensional accuracy, shape accuracy and surface quality. The United States and Japan consume cutting and The cost of grinding processing is as high as 100 billion US dollars and 1 trillion yen respectively. In 2007, my country had more than 3 million metal cutting machine tools. In the machinery manufacturing industry, green manufacturing is sweeping the world. However, in the chemically synthesized cutting fluids produced, sold and used in my country's market, a considerable part of the antirust agent still uses the carcinogen sodium nitrite, and some also contain harmful elements su...
