Metal surface grinding and polishing agent and preparation method thereof

Abstract

The invention relates to the technical field of metal surface treatment, in particular to a metal surface grinding and polishing agent and a preparation method thereof. The metal surface grinding andpolishing agent is prepared from the following ingredients in parts by weight: 16 to 33 parts of grinding agents, 1 to 2 parts of anti-foaming agents, 0.5 to 2 parts of sodium carbonate, 0.5 to 2 parts of surfactants, 0.5 to 2 parts of fatty alcohol ammonium sulfate, 0.5 to 1.5 parts of surface dimming agents, 0.5 to 1.5 parts of corrosion inhibitors, 0.2 to 0.5 part of suspending agents, 0.2 to 0.6 part of anticoagulants and 60 to 70 parts of water. By using the metal surface grinding and polishing agent provided by the invention, during the grinding and polishing on the metal surface, the multi-time coarse grinding and medium grinding links in the middle can be reduced; the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, more specifically, it relates to a metal surface grinding and polishing agent and a preparation method thereof. Background technique [0002] Polishing refers to the processing method of reducing the roughness of the workpiece surface by using mechanical, chemical or electrochemical action to obtain a bright and smooth surface. Polishing is a surface treatment process that uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. A smooth metal surface or mirror effect can be obtained by polishing the metal workpiece. [0003] During the production and processing of mobile phone and digital product accessories, the friction between the workpiece and the processing equipment, and the collision of the workpiece during transportation may cause wear marks, knife marks, etc. on the surface of the metal workpiece, and the remaining on ...

AI Technical Summary

Problems solved by technology

During the grinding process, due to the use of grinding particles with a particle size between 2-5um, deep scratches have been caused to the product workpiece in the first process, and it must be repaired by subsequent grinding to remove the scratches, so a long grinding is required time, the process is cumbersome, and the polishing effect is poor, the production efficiency is low, and it is not conducive to production

[0005] Chinese invention patent CN1654585A discloses the core / shell type nano particle abrasive polishing liquid composition and its preparation method. The polishing time is long and the polishing effect is good. However, in the preparation process of the above-mentioned abrasive polishing liquid, not only the reagents need to be mechanically stirred, but also the reagents need to be dispersed by means of ultrasonic dispersion or ball mill dispersion, and the preparation method is relatively cumbersome.
