Abstract

A disclosed chemical polishing fluid for aluminium parts is characterized by being prepared from the following raw materials in parts by weight: 7.5-9.5 parts of cerium oxide, 2-3 parts of erbium oxide, 3-5 parts of sodium aluminum silicate, 5-7 parts of bentonite, 4-6 parts of carbon fiber powder, 8-10 parts of glycol, 2.5-4 parts of docusate sodium, 3.5-5 parts of phosphoric pentoxide, 4-6 parts of TX-10, 7-9 parts of glycerin, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. The polishing fluid is reasonable in formula. By employing the cooperation of bentonite and other abrasives with the surfactant and other compositions, preferential adsorption is realized, and a long-term easily-cleaned physical adsorption surface is formed to improve the surface state. By adding the auxiliary agent, the polishing fluid has good wear resistance, dispersity, lubricity and film-forming property, and is capable of forming an air-obstructing layer on a workpiece surface and is capable of avoiding air corrosion under the synergic effect of a corrosion inhibitor. The polishing fluid is stable in quality, all polished positions are uniform in brightness, and the polishing fluid is suitable for polishing of aluminium parts.

Description

A kind of chemical brightening solution for aluminum component and preparation method thereof

Technical field

The present invention relates to technical field of surface, particularly a kind of chemical brightening solution for aluminum component and preparation method thereof.

Background technology

Chemical rightenning is the chemical corrosion under a kind of special conditions, it is to make metallic surface reach leveling and bright process of metal working by the dissolving of control metal selective, be subject to people's attention always, but, wanting steel substrate reaches comprehensive brightness effect and keeps word and pattern clearly, this has proposed requirements at the higher level to surface with chemical polishing technology, wherein just comprises chemical brightening solution.

The method application of aluminium alloying optical polishing is more extensive, but the maximum shortcoming existing is because polishing fluid temperature is high, reaction is fast, while production on automation line, station is long to next station required time, cause workpiece from chemical polishing bath out, carry a large amount of residual chemical rightenning liquid medicine and rest in the air, in dirty, the low process of raffinate simultaneously due to air exist effects on surface produce excessive erosion, oxidation form on surface heterochromatic etc. bad, thereby affected product quality.
