Problems solved by technology

[0003] At present, different types of fluxes on the market have different advantages and disadvantages. For example, hot air leveling flux has the advantages of less smoke, less layout residue, smooth and bright tin surface and no bad tin in reflow soldering during use, while wave soldering flux In use, it has the advantages of good tin rate, high insulation resistance, less layout residue, bright and full tin spots, and no halogen. The photovoltaic module welding material has less residue, high welding tensile strength and is suitable for various The advantages of different welding strips make different fluxes used when welding different materials, and the welding process is also different under some working conditions, which greatly reduces the use efficiency of fluxes. In the prior art, generally Flux is used to assist welding, but the existing flux is used in a single working condition, and some fluxes can only assist a single flux, which greatly reduces the working efficiency of the working user. great limitations

Abstract

The invention discloses an efficient soldering flux formula, and relates to the technical field of soldering flux. The efficient soldering flux formula is realized according to the following materials in parts by mass: 25-30 parts of rosin, 2 parts of rosin-modified phenolic resin, 1 part of rosin glyceride, 1 part of acrylic resin, 15-20 parts of absolute ethyl alcohol, 2 parts of butyl cellosolve, 1 part of dimethyl succinate sulfonate, 1 part of benzotriazole, 30-35 parts of xylene, 10-15 parts of benzene, 35-40 parts of deionized water and 2 parts of qualitative liquid. According to the efficient soldering flux formula, the rosin-modified phenolic resin and the rosin glyceride are used as auxiliary materials of a soldering flux, and the deionized water and the qualitative liquid are subjected to pressurizing and heating processes for treatment, so that the soldering flux can be matched with different types of soldering flux for use, and the different types of soldering flux can be conveniently used; and the soldering efficiency of workers is effectively improved, and the efficient soldering flux formula is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of flux, in particular to a high-efficiency flux formula. Background technique [0002] Flux is a chemical substance that can help and promote the soldering process in the soldering process, and at the same time has a protective effect and prevents oxidation reactions. Flux can be divided into solid, liquid and gas. There are mainly several aspects such as "auxiliary heat conduction", "removal of oxides", "reduction of surface tension of welded materials", "removal of oil stains on the surface of welded materials, increase of welding area", and "prevention of re-oxidation". The more critical role in this aspect is to remove oxides and reduce the surface tension of the material being welded. [0003] At present, different types of fluxes on the market have different advantages and disadvantages. For example, hot air leveling flux has the advantages of less smoke, less layout residue, smooth and bright tin s...
