Abstract

The present invention discloses an aqueous diamond grinding fluid with continuously suspending abrasives and a preparation method thereof, and belongs to the technical field of precision and ultra precision grinding processing. The grinding fluid comprises the following components in parts by weight: 0.1-5 parts of diamond abrasives, 0.01-2 parts of alkylphenol polyoxyethylene ether, 1-5 parts of modified polyurea N-methylpyrrolidone, 1-5 parts of N-methylpyrrolidone, 30-60 parts of an organic solvent, and 23-67.89 parts of water. According to the preparation method disclosed by the present invention, by using a surface modifying method, the diamond abrasives are modified by the alkylphenol polyoxyethylene ether, the modified diamond abrasives can be stably adsorbed on a molecular chain of the modified polyurea N-methylpyrrolidone; the bonding force between two is enhanced; meanwhile, by using the spatial network structure of a modified polyurea N-methylpyrrolidone molecule, the diamond abrasives are prevented from settling and aggregating to realize continuous suspending of the diamond abrasives, so that uniformly mixing operation before using the grinding fluid is saved, and the convenience in use is improved.

Description

technical field [0001] The invention relates to a water-based diamond grinding liquid in which abrasives are continuously suspended, and a preparation method of the grinding liquid, belonging to the technical field of precision and ultra-precision grinding. Background technique [0002] In the water-based diamond grinding liquid, due to the joint action of its own gravity and van der Waals force, the diamond abrasive will quickly settle and gather at the bottom of the container in a short time. Before using the grinding liquid, it usually needs to be re-shaken to disperse the deposited diamond abrasive at the bottom of the container bottle. The process is cumbersome, time-consuming and laborious, and this process greatly reduces the convenience of using the grinding liquid. [0003] The patent of invention with the publication number CN101186804A discloses a water-based diamond grinding liquid, mainly composed of diamond micropowder, suspending agent, dispersion stabilizer, ...
