Embodiment 1

[0062] Add 30.0g of ethylene glycol into a three-necked flask, dehydrate at 80°C for 60min, add 0.07g of boron trifluoride ether, and cool down to 70°C, slowly add 89.4g of epichlorohydrin into the flask drop by drop, and after the addition is complete, After oxychloropropane, the reaction was continued at 70°C for 1 hour, and then degassed under reduced pressure for 15 minutes. The solution was cooled to room temperature, and 103.0 g of 50% KOH aqueous solution was slowly added drop by drop. After the addition was completed, it was heated to 40° C. for about 2 hours, and the pH was measured to be 6.5. Afterwards, the temperature was raised to 80°C, and 0.17g of polyether refined preparation (magnesium silicate, CAS: 1343-88-0) was added, kept at 80°C for 1 hour, vacuum degassed until the water content of the solution was less than 0.1%, and filtered under reduced pressure to obtain 79.1g of the filtrate is ethylene glycol diglycidyl ether.

Abstract

The invention provides a quaternary ammonium salt polymer and a preparation method and application thereof. The structure of the quaternary ammonium salt polymer contains a hydrophilic group and adjustable hydrophilic/hydrophobic groups such as PPG and PAG. With high surface tension, the quaternary ammonium salt polymer can effectively separate miscellaneous oil wrapping metal cuttings and enablesthe miscellaneous oil to float above a metal processing aqueous solution, so demulsification can be effectively realized, the surface tension of the solution is increased, and the oil floats to a liquid level; and compared with an existing sedimentation additive for a metal working fluid, the quaternary ammonium salt polymer can effectively settle particles in the metal working fluid, and has good application prospects.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a quaternary ammonium salt polymer and a preparation method and application thereof. Background technique [0002] In the process of metal processing, the cutting and grinding of abrasive tools and processed materials will produce a large amount of metal chip powder. At the same time, during processing, the grease used will come into contact with the metal chip powder, which will form chip powder wrapped in miscellaneous oil. Due to the small particles of powder impurities and the low density of the oil wrapped in its outer layer, the wrapping will float in the processing fluid. This impurity-containing machining fluid will scratch the surface of the workpiece during recycling, resulting in unsatisfactory machining accuracy, reducing the performance and life of the metalworking fluid, and may also cause blockage of the filter element. [0003] At present, the method...
