Description
Technical field
The present invention relates to surface with chemical polishing technology, especially a kind of stainless steel chemical polishing solution and preparation method.
Background technique
Chemical polishing is to eliminate polishing scratch, leaching to the selective dissolution effect in the uneven region of sample surfaces by chemical reagent
Lose a kind of method of leveling.It is usually used in the chemical treatment to electronic component surface.In current chemical polishing solution, ingredient contains
There are a large amount of volatile hydrochloric acid and nitric acid, it is more serious to atmosphere pollution.Although some producers attempt to use hydrogen peroxide at present
Instead of the hydrochloric acid and nitric acid in polishing fluid, the case where to overcome chemical contamination, the polishing effect reached is also ideal.But
It is that there are a disadvantages for the polishing fluid, even if can acutely be decomposed because hydrogen peroxide is unstable when being polished, therefore the throwing
The service life of light liquid is shorter, using at higher.
Summary of the invention
The purpose of the present invention is to provide a kind of stainless steel chemical polishing solution and preparation method.The present invention, which has, can reduce
The characteristics of chemical contamination, polishing effect is good, long service life.
The invention is realized in this way.A kind of stainless steel chemical polishing solution, the polishing fluid of 1L be made of with following raw materials,
100~300ml of the concentrated sulfuric acid, 30~50ml of nitric acid,
5~9g of phenylpropyl triazole, 20~50g of lauryl sodium sulfate,
15~30ml of vinyl silanes, 2~6g of sodium metaphosphate,
Surplus is water；The concentrated sulfuric acid is the concentrated sulfuric acid of 92.5~98wt%；The nitric acid is the nitric acid of 50~70wt%.
In aforementioned stainless steel chemical polishing solution, the polishing fluid of 1L be made of with following raw materials,
150~280ml of the concentrated sulfuric acid, 35~46ml of nitric acid,
6~8g of phenylpropyl triazole, 25~45g of lauryl sodium sulfate,
18~25ml of vinyl silanes, 3~5g of sodium metaphosphate,
Surplus is water；The concentrated sulfuric acid is the concentrated sulfuric acid of 92.5~98wt%；The nitric acid is the nitric acid of 50~70wt%.
In stainless steel chemical polishing solution above-mentioned, the polishing fluid of 1L be made of with following raw materials,
Concentrated sulfuric acid 200ml, nitric acid 42ml,
Phenylpropyl triazole 7g, lauryl sodium sulfate 30g,
Vinyl silanes 22ml, sodium metaphosphate 4g,
Surplus is water；The concentrated sulfuric acid is the concentrated sulfuric acid of 92.5~98wt%；The nitric acid is the nitric acid of 50~70wt%.
The preparation method of stainless steel chemical polishing solution above-mentioned: the stainless steel chemical polishing solution of 1L is made in the steps below:
A, the water for measuring 400~500ml is spare；
B, it is slowly added to the concentrated sulfuric acid into water under stirring, drops to 45~50 DEG C to temperature, obtains A product；
C, it is slowly added to nitric acid in A product and mixes thoroughly, obtains B product；
D, B product are added in phenylpropyl triazole, obtain C product；
E, C product are added in lauryl sodium sulfate, obtain D product；
F, D product are added in vinyl silanes, obtain E product；
G, sodium metaphosphate is added to E product under stirring, obtains F product；
H, by F add water be made into 1L solution to get.
Compared with the prior art, the main component of stainless steel chemical polishing solution prepared by the present invention is the concentrated sulfuric acid and a small amount of nitre
Acid, ingredient is relatively simple, is easy preparation, and because not hydrochloric and contain only a small amount of nitric acid in part, therefore the polishing in polishing fluid
Liquid-based is originally not in volatilization phenomenon, effectively reduces atmosphere pollution.The component surface that the present invention polishes was because being not easy
Corrosion, so obtained component surface uniformity, quality is stablized.In addition to this, do not contain hydrogen peroxide in the present invention, use
Service life is long, is effectively saved production cost.
