Problems solved by technology

[0003] Existing metal polishing aids mainly include acid polishing liquid or metal polishing paste. Among them, acid polishing liquid has high protection requirements for users during use, and requires mechanical tools to have strong corrosion resistance. The waste liquid pollutes the environment greatly; there is no need for suitable mechanical tools during the use of metal polishing paste, and there is no problem of waste liquid polluting the environment. Therefore, metal polishing paste has received widespread attention
[0004] However, the traditional metal polishing paste has the disadvantage of slow polishing speed in the process of polishing the metal surface

Abstract

The invention provides metal polishing paste and a preparation method and application thereof. The metal polishing paste is prepared from the following components in parts by weight: 54-71 parts of superfine water, 5-9 parts of sodium alkyl sulfate, 2-4 parts of fatty alcohol-polyoxyethylene ether sodium sulfate, 13-18 parts of coconut oil diethanolamide, 3-5 parts of glycol distearate, 2-4 partsof saturated fatty acid, 12-15 parts of dodecylbenzene sulfonic acid, 1-1.5 parts of sodium hydroxide, 4.1-6.2 parts of an acidic pH value regulator and 2-4 parts of an emulsifier which comprises a binary condensation compound of alkylphenol and ethylene oxide. The invention also provides an application of the metal polishing paste in metal polishing. The flashing and grinding time of burrs on thesurfaces of a zinc alloy, an aluminum alloy, stainless steel, an iron piece and a powder metallurgic part can be shortened by adopting the metal polishing paste. By taking zinc alloy case buckle andbelt buckle as an example, a half time can be saved in roughing, deburring and flashing, and 1 / 2 time can be saved in fine polishing.

Description

technical field [0001] The invention relates to the technical field of metal material surface polishing aids, in particular to a metal polishing paste and its preparation method and application. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. Polishing is a modification of the surface of a workpiece using polishing tools, abrasive particles or other polishing media. Metal material surface polishing aids are commonly used polishing media for metal surface polishing. With the continuous development of industrial technology, the requirements for surface polishing aids are getting higher and higher. The surface processing of metal materials requires that the surface polishing aids used not only have Excellent surface cleanliness, can also efficiently remove scratches, realize surface glazing of metal materials, and improve corrosion...
