Abstract
The invention discloses a kind of polishing fluid of aluminum products, it is made up of the raw material of following parts by weight：30~65 parts of phosphoric acid, 55~85 parts of sulfuric acid, 0.2~2.5 part of aluminium salt, 0.05~0.2 part of ammonium persulfate, 0.04~0.18 part of sodium metasilicate, 0.01~0.3 part of thiocarbamide, 0.05~0.5 part of dithio dipropyl alcohol, 0.02~0.2 part of ethylenediamine tetramethylene phosphonic acid, 0.01~0.1 part of oil base hydroxyethyl imidazole quinoline.Polishing step is：Prepare polishing fluid；Polishing fluid is heated to 75 DEG C~110 DEG C；The polished aluminum products of dried and clean are immersed in polishing fluid, soak 20S~150S；Washed after aluminum products are taken out with 50 DEG C of deionized water；Drying.The polishing fluid of the present invention uses phosphoric acid, sulfuric acid, aluminium ion, strong oxidizer, corrosion inhibiter and brightener coordinated, the problem of being effectively prevented from aluminium excessive erosion, and polishing effect is good, efficiency high.
Description
Technical field
The invention belongs to the polishing technology field of metallic article, and in particular to a kind of polishing fluid of aluminum products and its polishing side
Method.
Background technology
The chemical polishing of aluminum products is the selectivity being produced on using aluminium and aluminium alloy in acid or alkaline electrolyte solution
From dissolution, with reduce its surface roughness, PH chemical processes.Chemical polishing has energy consumption small, simple to operate, raw
The advantages that producing efficiency high, not suffering from the product shape and size restrictions is in the processing of aluminum products surface finishing and its important process.Tradition
" three acid " technique for typically being coordinated using phosphoric acid, sulfuric acid, nitric acid of surface with chemical polishing technology, have that quality of finish is good, brightness height etc.
Advantage, but due to the use of nitric acid, have a large amount of tobacco (i.e. nitrogen oxides) generation in polishing process, cause serious environment
Pollution, endangers operator's health significantly.
The country is probably started to research of the aluminum products without tobacco chemical polishing in the 1980s, achieve some achievements,
But from the point of view of total situation, the polishing brightness (reflectivity) of no tobacco polishing is inadequate, it is impossible to reaches the bright of traditional three acid polishing
Degree and production requirement.Therefore, no tobacco surface with chemical polishing technology is above limited by very large in application.
The content of the invention
It is an object of the invention to provide a kind of polishing fluid of aluminum products, without nitric acid.
It is a further object of the present invention to provide a kind of polishing method of aluminum products, aluminum products surface finish is good, polishing
Brightness reaches tradition " three acid " technique.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of polishing fluid of aluminum products, is made up of the raw material of following parts by weight：30~65 parts of phosphoric acid, 55~85 parts of sulfuric acid,
It is 0.2~2.5 part of aluminium salt, 0.05~0.2 part of ammonium persulfate, 0.04~0.18 part of sodium metasilicate, 0.01~0.3 part of thiocarbamide, two thio
Two 0.05~0.5 part of propyl alcohol, 0.02~0.2 part of ethylenediamine tetramethylene phosphonic acid, 0.01~0.1 part of oil base hydroxyethyl imidazole quinoline.
Preferably, the mass concentration ratio of the phosphoric acid is 85%.
Preferably, the mass concentration ratio of the sulfuric acid is 98%.
Preferably, described aluminium salt is selected from least one of aluminum sulfate, aluminum phosphate and aluminium hydroxide.
A kind of polishing method of aluminum products, comprises the following steps：
S1：Formed by formula and prepare chemical polishing solution；
S2：Polishing fluid is heated to 75 DEG C~110 DEG C；
S3：The polished aluminum products of dried and clean are immersed in the polishing fluid in step S2, soak 20S~150S；
S4：With 50 DEG C of deionized water washing two to three times after aluminum products in step S3 are taken out；
S5：Dried up after aluminum products in step S4 are taken out.
The polishing fluid of the present invention uses phosphoric acid, sulfuric acid, aluminium ion, strong oxidizer, corrosion inhibiter and brightener coordinated, can
The problem of to be effectively prevented from aluminium excessive erosion, and may also be ensured that and imitated with preferable polishing effect and higher polishing
Rate.Nitric acid is free of in polishing fluid, can effectively mitigate gaseous contamination in polishing process and its to the person and environmental hazard.
