Abstract

The invention discloses an environment-friendly fully synthetic grinding fluid and a preparation method thereof. The fully synthetic grinding fluid comprises the following components in mass percentage: 20-40% of rust inhibitor, 5-15% of high cloud point polymer, polyethylene 5-15% of glycol, 0.3-5% of stabilizer, 0.3-5% of sedimentation agent, 0.1-1.0% of coupling agent, 0-0.5% of defoamer and the balance of water. The fully synthetic grinding fluid of the present invention uses boron-free carboxylate for rust prevention, environmental protection, easy biodegradation, and easy post-processing, and uses high cloud point polymer polyethylene oxide polypropylene oxide monobutyl ether For lubrication, the amount of coupling agent is greatly reduced, and the lubricity is better. The system is more stable, and the odor and cost of the original product are reduced, the cloud point is high, and it is safer and more stable. It is compounded with polyethylene glycol, coupling agent, sedimentation agent and other components, and the obtained grinding fluid has low foam and high sedimentation. , Extend the life of the working fluid, the fluid change cycle can reach at least one year, there is no "yellow robe" phenomenon, the lubricity is good, and the temperature of the working fluid is low and constant after processing.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to an environment-friendly fully synthetic grinding fluid and a preparation method thereof. Background technique [0002] Grinding fluid is an important supporting material for grinding. During the grinding process, both cutting and scoring and scratching occur between the grinding wheel and the material, generating a large amount of grinding heat, which is different from cutting methods such as turning and milling cutters. Different, turning and milling cutter cutting methods have about 70% to 80% of the heat gathered on the chips and flow away, about 10% to 20% of the heat is passed into the workpiece, and less than 5% is passed into the tool. The metal to be cut is relatively thin, about 60% to 90% of the heat is transferred to the workpiece, and only less than 10% of the heat is taken away by grinding, resulting in a large amount of grinding heat, and the temperature in t...
