Abstract
The invention discloses a kind of environment-friendly type nitric acid fog inhibitors, including following raw material: taking water as a solvent, volume ratio number meter by weight, urea 6-10g/L, citric acid 6-10g/L, sulfamic acid 6-10g/L, salt 8-12g/L, preparation method are as follows: mix urea, citric acid, sulfamic acid, salt, then slowly add water and stir to all dissolution to get.The present invention is used as additive, and the nitric acid slot after plating copper and tin is able to suppress NO2The acid mists such as gas, it is environmental-friendly, the irritating NO of yellow is not generated2Gas.Nitric acid fog inhibitor prepared by the present invention is rapid-action, after this agent is added, after a few minutes can automatical and efficient suppression mist, preparation method is simple, at low cost, safety and stability.
Description
Technical field
The present invention relates to electroless plating strip field, in particular to a kind of environment-friendly type nitric acid fog inhibitor.
Background technique
In electroplating process, typically use nitric acid as stripper.But nitric acid is a kind of deep-etching, it is toxic,
The liquid medicine of high pollution, it is high containing ammonia nitrogen, to equipment, to personnel, environment is influenced very big.Nitric acid when stripping the metals such as copper and tin,
Can emerge sharp aroma and NO2Toxic tobacco, these acid mists not only result in environmental pollution, and the workshop that can also corrode surrounding is set
Standby, facility, or even human health is had an impact.Therefore research and development use cost is cheap, suppression fog effect is good, corrosion mitigating effect
Good, environment amenable fog inhibitor, undoubtedly has important practical value.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of environment-friendly type nitric acid fog inhibitors.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of environment-friendly type nitric acid fog inhibitor, including following raw material: taking water as a solvent, by weight volume ratio number meter, urea 6-
10g/L, citric acid 6-10g/L, sulfamic acid 6-10g/L, salt 8-12g/L.
Preferably, including following raw material: take water as a solvent, by weight volume ratio number meter, urea 8g/L, citric acid 8g/L,
Sulfamic acid 8g/L, salt 10g/L.
Preferably, including following raw material: take water as a solvent, by weight volume ratio number meter, urea 6g/L, citric acid 6g/L,
Sulfamic acid 6g/L, salt 8g/L.
Preferably, including following raw material: taking water as a solvent, by weight volume ratio number meter, urea 10g/L, citric acid 10g/
L, sulfamic acid 10g/L, salt 12g/L.
The present invention also provides the preparation methods of the environment-friendly type nitric acid fog inhibitor: by urea, citric acid, sulfamic acid, salt
Mixing, then slowly add water and stir to all dissolution to get.
Compared with prior art, the invention has the following beneficial effects: the present invention uses as additive, is used in electro-coppering
Nitric acid slot after tin, is able to suppress NO2The acid mists such as gas, it is environmental-friendly, the irritating NO of yellow is not generated2Gas.System of the present invention
Standby nitric acid fog inhibitor is rapid-action, after this agent is added, after a few minutes can automatical and efficient suppression mist, preparation method is simple, at low cost,
Safety and stability.
Specific embodiment
It to facilitate the understanding of the present invention, below will be to invention is more fully described.But the present invention can be to be permitted
