Problems solved by technology

In hard water conditions, especially long-term water replenishment, a large amount of soap will be formed, and the accumulation of fatty acid soap will have a certain negative impact on the cutting fluid and machining process, which may lead to unstable emulsion and increase the consumption of concentrate
When soap is bonded together with foam, metal powder, miscellaneous oil and other components in the machine tool or in the centralized liquid supply system to form scum or even viscous substances, it will cause more problems. They float or accumulate on the In the working fluid, it will not only affect the filtration system, cause blockage, increase the consumption of filter paper, and poor sanitation on site, but also cause processing accuracy problems if it remains in the cutting tool, measuring tool and transmission system

Embodiment 1

[0083] The preparation of embodiment 1 polyisobutylene o-cresol

[0084] In a 500ml four-necked flask equipped with a stirrer, thermometer, condenser and dropping funnel, add 34.93g o-cresol, 6.88g catalyst boron trifluoride ether, 100ml n-hexane solvent and 161.61 polyisobutylene (Mn=1000) g was reacted at 80°C for 2h. After the reaction, use 5% potassium hydroxide solution to wash the reaction mixture once, and wash it with hot water to neutrality to remove the catalyst, then distill off the solvent and unreacted o-cresol under reduced pressure. The synthetic product is polyisobutylene o-cresol, and its hydroxyl value is 53.49 mg / g. The hydroxyl value determination method is the acetic anhydride method in GB / T7383-2007.

Embodiment 2

[0094] Add 45.66g of DB-1 detergent and dispersant prepared in Comparative Example 1 into a stirred 250ml reaction kettle, add 0.96g of hexamethylene diisocyanate (HDI), stir, and heat up to 90 °C, react at this temperature for 3.5 hours, stop heating, continue to pass nitrogen until the reactant cools to room temperature, collect the product, and obtain the Mannich base urea derivative dispersant MN-1 of the present invention.

Embodiment 3

[0096] Add 44.12g of the DB-2 detergent and dispersant prepared in Comparative Example 2 into a stirred 250ml reaction kettle, add 4.71g of hexamethylene diisocyanate (HDI), stir, and heat up to 100 °C, react at this temperature for 4 hours, stop heating, continue to pass nitrogen until the reactant is cooled to room temperature, collect the product, and obtain the Mannich base urea derivative dispersant MN-2 of the present invention.

Abstract

The invention provides a fully synthetic cutting fluid composition, a method for improving the anti-hard water stability of the fully synthetic cutting fluid, and a method for improving the antirust performance of the fully synthetic cutting fluid. The fully synthetic cutting fluid composition of the present invention includes a Mannich base urea derivative dispersant, an emulsifier, an alkali retaining agent and a balance of water, wherein the preparation method of the Mannich base urea derivative dispersant comprises : (1) In the presence of an alkylation catalyst, react phenol and / or mono-ortho-alkylphenol with polyolefin to collect the alkylation product; (2) combine the alkylation product obtained in step (1) with Mannich reaction of polyene polyamine and aldehyde to obtain Mannich base product; (3) reacting the Mannich base product of step (2) with isocyanate to collect the product. The fully synthetic cutting fluid composition of the present invention has excellent stability against hard water and antirust performance, and can fully meet the requirements for use in areas with relatively high water hardness.

Description

technical field [0001] The invention relates to a fully synthetic cutting fluid composition, in particular to a fully synthetic cutting fluid composition with excellent hard water resistance stability and antirust performance. Background technique [0002] Cutting fluid plays the role of lubricating and cooling processing tools and components in the process of metal cutting, and its performance index directly affects the quality, efficiency and cost of cutting processing. Water-based metal cutting fluid came out in the 1940s. With the development of technology, a fully synthetic cutting fluid appeared on the market. It is composed of surfactants, water-soluble anti-rust agents and water-soluble lubricants. It is a granular The extremely small colloidal solution has good wettability, strong penetrating ability, good cooling and cleaning performance, and also has a certain lubricating effect, and its stability is better than that of emulsion, and the service life is longer.
