[0099] Preparation method of emulsified cutting fluid, system temperature control

[0100] In the present invention, the temperature control of the system is not particularly limited, usually at 10-35°C, first add rust inhibitors and preservatives during softening, and then add organic alcohol amines, base oils, surfactants, and composite lubricants in sequence , bactericide, anti-hard water agent, finally add anti-foaming agent, stir until the system is uniform and clear to obtain the emulsified cutting fluid;

[0101] If the system temperature is less than 10°C, it is easy to cause difficulty in stirring due to the low temperature of the system, and the emulsified oil will become unstable; while the temperature of the system is greater than 35°C, due to the high temperature of the system, the water will volatilize seriously during the stirring process, and the mass fraction will not be stable. Accurate, etc., with no other beneficial effects.

Abstract

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.

Description

technical field [0001] The invention belongs to the field of chemical products, in particular to an emulsified cutting fluid and a preparation process thereof. Background technique [0002] Cutting oil is a lubricating medium used in the metal cutting process, and its most important functions are lubrication, cooling, chip removal and rust prevention to obtain good surface accuracy and workpiece quality, while prolonging the service life of the machine tool. Oil-based cutting oil is often used in cutting processes that are difficult to process or have high requirements for lubricity. With the use of cemented carbide tools and the increase in the speed of machine tools, the application of water-based cutting fluids has emerged. Water-based cutting fluids are divided into three categories: emulsified type, microemulsion type, and fully synthetic type. Among them, compared with the other two cutting fluids, the emulsified cutting fluid (emulsified oil) has better lubricating p...
