Emulsified cutting fluid and preparation method thereof

The invention discloses an emulsified cutting fluid and a preparation process thereof. The product comprises the following components in percentage by weight: 50-70% of base oil, 14-25% of a surfactant, 1-4% of an antirust agent, 0.2-1% of a preservative, 3-7% of a composite lubricant, 2-10% of organic alcohol amine, 2-3% of a bactericide, 2-4% of a hard water resisting agent, 0.1% of an anti-foaming agent and the balance of softened water. The raw materials are added according to a certain sequence and proportion and then stirred to obtain the emulsified cutting fluid. Compared with the traditional emulsified oil preparation process, no intermediates subjected to chemical reaction is needed to be added, and the production and preparation process is simple and easy to operate. The cuttingfluid provided by the invention has good lubricating property, and can be used for processing materials such as cast iron, steel, stainless steel, copper, copper alloy, magnesium alloy and the like. 本发明公开了一种乳化型切削液及其制备工艺，该产品组分
