Abstract
The invention discloses a printed circuit board aqueous cleaning compound. The printed circuit board aqueous cleaning compound comprises sodium ethoxylated alkyl sulfate, secondary alkane sulfonate, a nonionic surfactant phosphate, a copper corrosion inhibitor, an anti-oxidant, sulfamic acid and citric acid. The printed circuit board aqueous cleaning compound is suitable for use before printed circuit board printing and has the advantages and characteristics of good cleaning effects, solvent reduction and work environment improvement.
Description
Technical field
The present invention relates to electronic industry printed-wiring board (PWB) cleaning field, espespecially a kind of printed-wiring board (PWB) waterborne cleaning agent.
Background technology
In electron trade; most enterprise is all at use printed-wiring board (PWB); printed-wiring board (PWB) needs to remove the pollutent carried in former production process before printing; such as greasy dirt, dust and fragment etc., then start at printed thereon protective membrane, protects the Copper Foil stayed; what stay has been exactly circuit; unnecessary just removes with chemical process, then cleans, so that later solder mask and the printing helping weldering paint.Therefore, cleaning is an important step of electronic manufacture.Traditional trichloroethane and the solvent cleaner of CFC were once once controlled the market, but, because they are to the Latent destruction power of ozone, substitute by other all kinds of SOLVENTS type clean-out systems.These leaning solvents are mainly divided into three kinds now: inflammable leaning solvent, nonflammable leaning solvent and nonflammable halogenated solvent type clean-out system.This three types respectively has relative merits, but leaning solvent is fast, the independent used clean-out system of volatilization on the whole, but they need specific installation and ventilation plant in order to avoid be subject to the injury of toxicity and other potentially dangerous.Waterborne cleaning agent is the substitute of harm ozonosphere chemical, and can decrease the discharge of solvent simultaneously.
Summary of the invention
The present invention is a kind of containing printed wiring board cleaning agent after the components welding of Terpineol 350 by-product terpenes, it is characterized in that the deficiency overcoming above-mentioned leaning solvent technology, a kind of waterborne cleaning agent being suitable for printed-wiring board (PWB) and using before printing is provided, realizes decreasing the discharge of solvent and the object of clean cleaning printed-wiring board (PWB).
To achieve these goals, technical solution of the present invention is: a kind of printed-wiring board (PWB) waterborne cleaning agent is made up of ethoxylated alkyl sulfate, Seconary Alkane Sulphonate Sodium, nonionogenic tenside phosphate ester salt, copper inhibitor, antioxidant, thionamic acid and citric acid, and each component and mass percentage thereof are:
Ethoxylated alkyl sulfate 3 ~ 4%
Seconary Alkane Sulphonate Sodium 2 ~ 3%
Nonionogenic tenside phosphate ester salt 1 ~ 2%
Copper inhibitor 0.05 ~ 0.2%
Antioxidant 1 ~ 3%
Thionamic acid 4 ~ 8%
Citric acid 2 ~ 4%
Water 76 ~ 85%
Further, described copper inhibitor is methyne 124 Triazole, is the fluid cpds with following formula:
In formula, R
1for hydrogen or alkyl; R
2and R
3for C2 ~ C8 hydroxyalkyl;
Described nonionogenic tenside phosphate ester salt preferred alkyl glucosides phosphate ester salt;
Described antioxidant is one or both in phytic acid and xitix.
Preparation method of the present invention is: under the condition stirred, thionamic acid and citric acid are dissolved in the water, at the temperature of 10 DEG C ~ 30 DEG C, keep stirring, add antioxidant, ethoxylated alkyl sulfate, Seconary Alkane Sulphonate Sodium, nonionogenic tenside phosphate ester salt and copper inhibitor more successively, continue stirring after each components dissolved, stop stirring, filter to obtain product.
Advantage and disadvantage of the present invention is: be suitable for the waterborne cleaning agent that printed-wiring board (PWB) uses before printing, have and clean up, and decreases solvent and improves the advantage and disadvantages such as Working environment.
