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.

Abstract

The invention relates to a water-soluble cutting fluid which contains the following components in parts by weight: 4.5-20 parts of polymer latex, 10-26 parts of triethanolamine, 1-7 parts of sodium benzoate, 1-7 parts of borax, 0.5-6 parts of benzotriazole, 3-16 parts of monoisopropanolamine, 10-26 parts of polyethylene glycol, 0.5-3 parts of polysiloxane defoaming agent and 15-30 parts of water, wherein the polymer latex comprises the following components in percentage by weight: 10-30% of polystyrene homopolymer colloidal particle, 0.5-5% of water-soluble emulsifier and the balance of water. In the invention, the water-soluble cutting fluid is favorable in stability, dispersity, lubricating property and extreme pressure antiwear property.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a water-soluble cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. Good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional soap-based emulsions, which are easy to smell in summer, difficult to dilute in winter, and poor in anti-rust effect, and has no adverse effect on lathe paint. [0003] The performance of cutting fluid depends on its composition, and cutting fluid is usually divided into two categories: non-water-soluble (oil-based) fluid and water-soluble (water-based) fluid. Oil-based cutting fluids have better lubricating properties and poorer cooling effects. Compa...
