Abstract

The invention relates to amine phosphates and a preparation method thereof. The amine phosphates allow the hard water resistant stability of a cutting fluid to be substantially improved when an additive in the invention improves the emulsification capability, the lubrication performance and the antirust performance of the cutting fluid. According to the invention, a molecular structural formula of the amine phosphates is shown in the specification, and in the molecular structural formula, X is S or O, R is a long chain alkene group of C8-C100, R1 is hydramine or alkamine, and n is from 1 to 100. Above technical scheme allows problems in the specification to be well solved, and the amine phosphates can be used in industrial production of water-based cutting fluids.

Description

technical field [0001] The invention relates to a phosphoric ester amine salt and a preparation method thereof. Background technique [0002] With modern CNC machine tools, machining centers and other processing equipment becoming more and more precise, high-speed, and fully functional, there are more and more types of processing materials, and the requirements for the surface quality of workpieces are gradually improving, and higher and higher performance requirements are also put forward for metal processing fluids. , such as high performance, long life, green environmental protection, etc. With the increasingly stringent requirements of "low energy consumption, low cost, and low pollution", metalworking fluids are rapidly transitioning from oil-based to water-based. Water-based metalworking fluids came out in the 1940s, which have incomparable cooling performance with oil-based fluids and are low in cost. So far, water-based fluids have far surpassed oil-based fluids in...
