Description
Technical field
The present invention relates to the method for a kind of Biocidal algae-killing agent for the circuit board manufacture tank and preparation method thereof and sterilization algae removal.
Background technology
In the time of processing circuit board, the bacterium in the tank, microorganism will be improved the defect rate of processing greatly, analyze according to on-the-spot defect rate statistics, have the substandard products more than 50% relevant with bacterium and microorganism in the tank.
In order to improve the yield rate of circuit board processing, in tank, often need to add such as the chloride bactericide that waits, realize the function of sterilization algae removal.But in reality is used, but find, chloride material often with circuit board in some composition react, can reduce the quality of circuit board.In addition, behind the sterilization algae removal material such as bacterium corpse can with tank in some inorganic matter form precipitation, after using for a long time, must clean these precipitations.For example, if general 2 time-of-weeks do not clean, defect rate will significantly be deducted a percentage, and increases by 50% at least.So not only can influence the quality of circuit board, and also must stop work cleaning sink the time, further can influence the efficient of production.
Summary of the invention
Technical problem to be solved by this invention is, the method of a kind of Biocidal algae-killing agent for the circuit board manufacture tank and preparation method thereof and sterilization algae removal is provided, can not chloride composition, and be difficult for generating precipitation, do not need, perhaps the minimum long period does not need to carry out washing trough.
The present invention at first provides a kind of preparation method of the Biocidal algae-killing agent for the circuit board manufacture tank, comprises the steps:
First blend step: the aqueous mixtures mixing stirring that will comprise the isothiazolinone of 1 to 3 part of quality, 0.5 to 10 part of quality dodecyl dimethyl benzyl ammonium bromide and 5 parts of 20 parts of quality obtains first mixed liquor;
Second blend step: described first mixed liquor is heated to 50 to 80 degrees centigrade, adds the organic solvent of 3 to 8 parts of quality again, mixed to few 60 minutes, obtain second mixed liquor;
The 3rd blend step: described second mixed liquor is cooled to 0 to 8 degree centigrade, progressively adds sour agent, mix and stir, make its pH value arrive 3 to 5, obtain the Biocidal algae-killing agent for the circuit board manufacture tank.
Accordingly, the present invention also provides a kind of Biocidal algae-killing agent for the circuit board manufacture tank, adopts described preparation method to prepare.
Accordingly, the present invention also provides a kind of method of the sterilization algae removal for the circuit board manufacture tank, and Biocidal algae-killing agent as claimed in claim 6 is added the water dilution of 20 to 100 times of volumes, and the injection circuit plate prepares tank to be used.
Preferably, described organic solvent adopts ethylene glycol, uses the ethylene glycol of 5 parts of quality in described second blend step.
Preferably, citric acid is adopted in described sour agent.
Preferably, in described first blend step, adopt the dodecyl dimethyl benzyl ammonium bromide of the isothiazolinone of 2 parts of quality, 2 parts of quality and the mixture mixing stirring of 10 parts of quality to obtain first mixed liquor.
Preferably, (CAS No. 26172-55-4 2682-20-4) mainly is made up of 5-chloro-2-methyl-4-isothiazoline-3-ketone (CMI) and 2-methyl-4-isothiazoline-3-ketone (MI) described isothiazolinone.
Compared with prior art, the advantage of technical scheme of the present invention is:
Have the effect of sterilization algae removal preferably, improved the yield rate of circuit board greatly.And adopted not chloride prescription, not can with circuit board in electroplating process with relevant plating liquid medicine composition generation chemical reaction.And, because compound acid and organic solvent are difficult for forming precipitation, further improved formation efficiency and yield rate.
Especially it is emphasized that and Biocidal algae-killing agent of the present invention in each composition, if do not adopt preparation method of the present invention, only adopt and mix merely, then physical characteristic is extremely unstable, for example situations such as precipitation, layering can occur, is difficult to use in reality.And the physical aspect of Biocidal algae-killing agent of the present invention is stable, is convenient to storage and transportation, uses also very convenient.
