[0044] The preparation process of the microemulsion cutting fluid of the present invention comprises:
[0045] S1: Prepare the water phase system, under continuous heating and stirring, add the preset weight part of water into the container, slowly add the preset weight part of the processing aid soluble in the water phase, and fully dissolve;
[0046] S2: Prepare the oil phase system, under continuous stirring and heating, add the base oil, additives and processing aids soluble in the oil phase in sequence in the reaction kettle, and mix well;
[0047] S3: Prepare the microemulsion system, under continuous stirring and heating, slowly add the prepared water phase system to the oil phase system, and mix well;
[0048] S4: standing still to obtain the finished microemulsion cutting fluid. Each process step is described below:
[0049] Before the preparation process, it is necessary to set the types of processing aids and the weight of each component. According to the nature a...
