Abstract

The invention discloses semisynthetic metal cutting fluid with trimethylolpropane oleate serving as base oil and a preparation method of the semisynthetic metal cutting fluid. The semisynthetic metal cutting fluid comprises the trimethylolpropane oleate, nonionic surfactants, anionic surfactants, antirust agents, cosolvents, extreme pressure agents, defoaming agents, bacteriacide and water. The preparation method of the semisynthetic metal cutting fluid includes: adding the extreme pressure agents into the base oil with uniform stirring so that solution A is obtained; then sequentially adding the defoaming agents, the antirust agents, the cosolvents and the bacteriacide into the water with uniform stirring so that solution B is obtained; and mixing the solution A with the solution B, and stirring while slowly dropwise adding the nonionic surfactants and the anionic surfactants so that a homogeneous and clarified micro-emulsion system, namely, the semisynthetic metal cutting fluid with the trimethylolpropane oleate serving as the base oil is obtained finally. The semisynthetic metal cutting fluid has good lubricity and biological degradability, has low-toxicity and low-harm to human bodies and the environment and is suitable for metal machining of most materials.

Description

technical field [0001] The invention relates to a semi-synthetic metal cutting fluid with trimethylolpropane oleate as base oil and a preparation method thereof. Background technique [0002] Metal cutting fluid is a kind of metal processing fluid. During the cutting process, it acts as an intermediary between the workpiece and the tool to lubricate, cool, and prevent metal chips from adhering, reducing friction during the cutting process and reducing tool wear. And energy loss, to ensure the accuracy and smoothness of processing. Most traditional cutting fluids use mineral oil as the base oil. Mineral oil is refined from crude oil. The technology is mature and the price is cheap. However, the composition of mineral oil is complex and diverse, containing paraffins with different carbon numbers ranging from 12 to 40. Alkanes and aromatic hydrocarbons have very weak mobility in soil and poor biodegradability. The small hydrocarbon molecules in them stay in the soil for a long...
