Background
The traditional soldering process uses an open type soldering furnace, a soldering wire and a common soldering flux, wherein the soldering wire is generally composed of two parts of tin alloy and the common soldering flux, and the common soldering flux has the effects of improving auxiliary heat conduction of the soldering wire in the welding process, removing oxidation, reducing the surface tension of a welded material, removing greasy dirt on the surface of the welded material and increasing the welding area; the flux is usually a rosin resin flux composed of rosin, resin, halide-containing active agent, additive and organic solvent. The soldering flux has good weldability and low cost, but waste gas is filled in the air when soldering tin exists after soldering, so that soldering tin in a production workshop is very sharp in smoke smell, and the environment of the workshop is bad while the soldering tin is wasted, thereby affecting the physical health of workers.
Disclosure of Invention
The technical problem to be solved by the invention is to provide the soldering flux for reducing the exhaust emission treatment, which can reduce the exhaust emission treatment, improve the production efficiency, save the labor cost for enterprises and improve the product quality. Namely: the production efficiency is improved by 30%, the product quality is improved by 18%, and the air index reaches PM2.5.
In contrast, the soldering flux for reducing the exhaust emission treatment provided by the invention is transparent smokeless washing-free type; the preparation method comprises the following steps of: 10% of rosin, 10% of rosin ester, 7% of acrylate modified butadiene resin, 5% of polyethylene, 5% of polyurethane, 5% of furfural resin, 1% of octyl phenol polyoxyethylene ether, 2% of succinic acid, 1.6% of anhydrous citric acid, 1% of benzoic acid, 0.4% of dimethylbenzene, 50% of dimethyl methanol, 1% of benzotriazole and 1% of hexamethylenediamine; wherein the rosin and rosin ester are formed as a modified rosin resin; the acrylic ester modified butadiene resin, polyethylene, polyurethane and furfural resin form a film-forming reinforcing agent; the octyl phenol polyoxyethylene ether, the succinic acid, the anhydrous citric acid, the benzoic acid and the dimethylbenzene are compounded to form an organic acid activator;
crushing rosin and rosin ester by a crusher, wherein the crushing fineness is 100 meshes; mixing octyl phenol polyoxyethylene ether, succinic acid, anhydrous citric acid, benzoic acid and dimethylbenzene according to the component formula ratio at normal temperature, pouring into a stainless steel container filled with dimethyl methanol, stirring for 0.5 hour, adding benzotriazole and hexamethylenediamine, and stirring for 0.5 hour; standing for 1 hour; and adding the mixed powder of rosin and rosin ester while stirring until the mixed powder is completely dissolved, stopping stirring, and standing for 4-6 hours to obtain the transparent smokeless washing-free soldering flux.
Compared with the prior art, the invention has the beneficial effects that: the invention adopts a film forming reinforcing agent composed of acrylate modified butadiene resin, polyethylene, polyurethane and furfural resin, has proper softening point, and the softening point is 90-100 ℃, and the welding spot is not yellow and transparent and clean after welding. The waste gas generated during soldering tin is very little, the production efficiency is improved, the workshop environment is improved, the energy is saved, the environment is protected, the damage to the physical health of workers is avoided, the product quality is improved, the production efficiency is improved by 30%, the product quality is improved by 18%, and the air index reaches PM2.5.
