Water-based environment-friendly antirust aluminum foil punching shear fluid and preparation method thereof

The invention relates to the field of lubricating oil, in particular to water-based environment-friendly rust-proof aluminum foil punching and shearing fluid and a preparation method thereof.The water-based environment-friendly rust-proof aluminum foil punching and shearing fluid is prepared from, by mass, 0.3%-1.5% of a lubricating agent, 0.2%-1.5% of a corrosion inhibitor, 0.1%-1% of an emulsifying agent, 0.05%-0.5% of a sterilizing agent, 0.2%-1% of a rust inhibitor, 0.1%-1% of a PH regulator, 0.001%-0.01% of a defoaming agent and the balance water. The deionized water is supplemented to 100%. The punching and shearing fluid is an energy-saving and environment-friendly aluminum foil processing fluid produced in a green manner, has the advantages of good lubricity, no VOC emission, safety in use by human bodies, certain cooling performance, low cost and mold protection, and especially has excellent antirust performance on cast iron, copper and aluminum metals. 本发明涉及润滑油领域，具体涉及一种水基环保防锈铝箔冲剪液及其制备方法，该水基环保防锈铝箔冲剪液
