Mechanical equipment stainless steel material polishing agent and preparation method thereof

Abstract

The invention discloses a mechanical equipment stainless steel material polishing agent. The mechanical equipment stainless steel material polishing agent comprises, by weight, 5-10 parts of triethanolamine, 0.5-1.5 parts of surfactant, 7-11 parts of inorganic acid, 1-3 parts of sodium nitrite, 3-5 parts of hydrogen peroxide, 2-4 parts of a stabilizing agent, 5-9 parts of compound additives, 1-3 parts of nanometer silicon dioxide, 1-2 parts of nanometer zinc oxide, 0.1-0.3 part of a corrosion inhibiting agent and 40-50 parts of distilled water. The polishing agent has the beneficial effects of being good in polishing quality, convenient to use, high in efficiency and the like, is free of the powder dust phenomenon and is free of chromic anhydride type toxic substances in the polishing process, the requirement for the waste water treatment condition is lowered, the abrasive dispersity of the polishing agent is good, the composition stability is good, and the surface evenness and the micro spine phenomenon effect of polishing on a mechanical equipment stainless steel material are remarkable; and meanwhile the preparation method of the mechanical equipment stainless steel material polishing agent is low in material cost, raw materials are easy to obtain, the process is concise, and high practical value and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a polishing agent for stainless steel materials of mechanical equipment and a preparation method thereof. Background technique [0002] After metal parts are processed, there is usually a layer of oil or other chemical agents attached to the surface. After a period of use, the metal parts will be corroded by the use environment, and rust will appear on the surface. Therefore, many metal parts need a certain brightness. Polishing treatment is an important part of parts processing. Polishing agents are often added during the polishing process to improve the brightness of metal parts and clean the metal surface. However, the existing polishing agents have problems such as quick rust return, narrow applicable metal types, and incomplete cleaning. Many polishing agents contain fluorine compounds or phosphorus-containing compounds, which pollute the environment. Moreover...

Problems solved by technology

At present, the existing electrochemical polishing in most factories cannot be mass-produced due to energy consumption. At the same time, the appearance of stainless steel products is complicated. When electrochemical polishing is used to polish parts with blind holes, the surface of the inner hole is Low current density area, unable to achieve satisfactory polishing effect on its inner surface

Mechanical polishing is generally more polluting and requires more workers. Although electrochemical polishing is effective, it needs to make special fixtures. For parts with complex shapes, due to the uneven distribution of power lines, it is easy to have different internal and external polishing effects, and there are yin and yang surfaces. In some cases, it is greatly affected by the power line, and the energy consumption is high. If you do not use polluting polishing liquid components, such as chromic anhydride (highly toxic chemicals), the polishing effect is often poor
