Environment-friendly cation emulsified water-based cutting fluid and preparation method thereof

Abstract

The invention relates to an environment-friendly cation emulsified water-based cutting fluid and a preparation method thereof. The preparation method is characterized by comprising the following steps: preparation of a component A: respectively adding 3-8% of quaternary ammonium salt, 5-8% of Tween -40, 0.05-0.2% of calcium chloride, 0.01-0.08% of magnesium sulfate, 16-30% of gear oil 200# and 54-76% of deionized water into a reaction kettle for uniformly stirring, heating the mixture until the temperature is within 45-65 DEG C, and keeping the temperature for 20-30 minutes to obtain the component A; preparation of a component B: respectively adding 20-40% of extreme pressure antiwear additive, 2-10% of preservative, 5-20% of antirust, 0.04-0.3% of calcium chloride, 0.01-0.06% of magnesium sulfate and 30-72% of the deionized water into the reaction kettle for uniformly stirring, heating the mixture until the temperature is within 55-75 DEG C, and keeping the temperature for 25-35 minutes to obtain the component B; and after the component A and the component B are prepared, mixing and stirring the component A and the component B according to the mass ratio of 2:1-1:2 to be invalid, heating the mixture until the temperature is within 65-80 DEG C, keeping the temperature for 35-45 minutes, and then cooling to normal temperature to obtain the product of the invention. The product of the invention has the advantages of high wear resistance, water solubility and lubricating property, good anti-rust property, no corrosion, good cooling property, convenient cleaning, cheap price and the like.

Description

technical field [0001] The invention relates to an environment-friendly cationic emulsified water-based cutting fluid applied to metal machining and a preparation method thereof. Background technique [0002] At present, the research and use of water-based micro-emulsion cutting fluids have been used for many years at home and abroad. Since water-based cutting fluids are used after diluting the concentrated solution with a large amount of water, oily smoke and fires will not be generated. Water has a large specific heat and high thermal conductivity of vaporization, so it is a very good coolant with low cost. In addition, the degreasing cleaning after processing is relatively simple. However, compared with oil-based cutting fluids, domestic products have slightly poorer lubricity and anti-rust properties, and are easily affected by bacteria, causing corrosion, and the cost of treatment after discharge is high. Although the quality of foreign products is better, they are mor...
