| titleOfInvention | Water-based cleaning-free flux for lead-free welding flux and preparation method thereof |
| abstract | The invention discloses a water-based cleaning-free flux for a lead-free welding flux and a preparation method thereof. The flux is suitable to be coated on the welding surface of a printed circuit board by a spraying and dipping mode, and mainly comprises deionized water, a composite mixed activator, a surface active agent, a composite mixed cosolvent, a film-forming agent, a corrosion inhibitor, a microorganism growth inhibitor, and the like. According to the water-based cleaning-free flux for the lead-free welding flux, prepared by the invention, the content of a VOC (Volatile Organic Compound) is lower than 5%, so the environmental-friendliness is achieved; and as necessary, the microorganism growth inhibitor is added, so that the water-based cleaning-free flux has certain stability during the storage process. The water-based cleaning-free flux for the lead-free welding flux, prepared by the invention, has the comprehensive advantages that halogen is free, residuals are fewer, cleaning is free, dielectric resistance is high, combustion is difficult, the storage and the transportation are convenient, the environmental-protection effect is achieved, and the like; the combined circuit is simple and rapid, the raw materials are easy to obtain, and the price is lower; and the water-based cleaning-free flux for the lead-free welding flux is suitable for large scale preparation and industrial production. |
