Embodiment 1
[0022] A water-soluble cutting fluid, containing the following components by weight: polymer latex 4.5-20, triethanolamine 10-26, sodium benzoate 1-7, borax 1-7, benzotriazole 0.5-6, monoiso Propanolamine 3-16, polyethylene glycol 10-26, polysiloxane defoamer 0.5-3, water 15-30;
[0023] Wherein, the polymer latex includes, by weight percentage: 10-30% of polystyrene homopolymer micelle, 0.5-5% of water-soluble emulsifier, and the rest of water.
Embodiment 2
[0025] In this embodiment, a water-soluble cutting fluid contains the following components in parts by weight: polymer latex 5, triethanolamine 25, sodium benzoate 1, borax 1, benzotriazole 0.5, monoisopropanolamine 15, Polyethylene glycol 25, polysiloxane defoamer 0.5, water 30; wherein, the polymer latex contains: 30% polystyrene homopolymer micelle; 5% sodium dodecylsulfonate; the balance of water.
[0026] The preparation method of the polymer latex comprises the following steps: mix the above-mentioned amount of styrene, water and sodium dodecylsulfonate, and obtain a stable emulsion by electromagnetic stirring for 30 minutes; The polymerization reaction was carried out for 10 hours. After the reaction was completed, a small amount of polymer precipitation that may be generated was filtered to obtain a polymer latex. Observation by a transmission electron microscope showed that the colloidal particles were spherical, with an average particle size of 102nm.
