Abstract

The invention discloses an environment-friendly polishing solution and a preparation method thereof. The polishing solution is prepared from, by weight, 4-13 parts of methyldiethanolamine, 8-16 parts of graphite powder, 3-10 parts of sodium silicate, 2-8 parts of liquid paraffin, 2-5 parts of alkylphenol ethoxylates, 2-6 parts of aspartic acid, 2-4 parts of potassium citrate, 4-9 parts of silica gel powder, 4-7 parts of vermiculite power, 1-5 parts of sodium alga acid, 3-8 parts of fatty acid diethanol amide, 2-10 parts of alkyl glycoside, 15-40 parts of formic acid, 10-25 parts of ethylene glycol and 35-60 parts of water. The polishing solution prepared through the method has good environmental friendliness, and meanwhile a good polishing effect is kept.

Description

technical field [0001] The invention belongs to the field of material surface treatment, and relates to a polishing liquid, in particular to an environment-friendly polishing liquid and a preparation method thereof. Background technique [0002] In the machining process, it is often necessary to polish various metal materials before electroplating or coating to protect the metal materials and make the surface of the materials more beautiful. Commonly used polishing methods include mechanical polishing, chemical polishing, and electrochemical polishing. Compared with other polishing methods, chemical polishing is the most widely used in mechanical processing due to its advantages of simple operation, high efficiency, low cost, and not being affected by the shape of the polished piece. Polishing fluid is one of the key elements in chemical polishing, which determines the quality of polishing. The polishing liquid is mainly composed of abrasives, oxidants and surfactants. Mo...
