Abstract

The invention relates to a water base emulsified cutting fluid which comprises the following components in parts by weight: 30-55.5 parts of mineral oil, 9.5-21 parts of pentaerythritol fatty acid compound ester, 0.4-2.1 parts of benzotriazole, 4-11 parts of diglycol, 2.5-11 parts of isopropanolamine, 4.5-16 parts of boric acid, 9.5-21 parts of polyethylene glycol, 0.091-1.1 parts of a polysiloxane defoamer, and 19-41 parts of water. The invention further discloses a preparation method of the water base emulsified cutting fluid. The method comprises the following steps of: weighing the mineral oil and polyethylene glycol in parts by weight, starting stirring and heating to 120 DEG C, performing a reaction for 1-2 hours at constant temperature and cooling to 70-80 DEG C; and then sequentially adding the balance of components, and stirring for reaction for 30-60 minutes to obtain a finished product. The water base emulsified cutting fluid provided by the invention not only has high lubricity, high anti-rust property, high emulsibility and high stability and long service life, but also is free from environmental pollution and damage to human body, so that the fluid can satisfy the cutting demands of various metals.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a water-based emulsified cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting is a widely used processing method. During the cutting process, a lot of friction and heat will be generated between the tool and the workpiece, which not only affects the processing efficiency and the quality of the workpiece, but also causes damage to the tool and equipment. Therefore, cutting fluids with good lubricating, cooling, cleaning and anti-rust properties are the goals that have been pursued in metal cutting. [0003] 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 ...
