| titleOfInvention | A kind of flux paste for cemented carbide-tool steel cutting tools and preparation method thereof |
| abstract | The invention provides a flux paste for cemented carbide-tool steel cutters, which is prepared from the following raw materials in parts by weight: 3-4.5 parts of borax powder, 2.5-4 parts of boric acid powder, and 1-2 parts of potassium tetraborate powder. parts, 1-1.5 parts of potassium fluoroborate powder, 0.02-0.05 parts of glycerol, 2.5-3.5 parts of distilled water, 0.05-0.08 parts of hydroxyethyl cellulose, and 0.01-0.03 parts of sodium benzoate. The present invention also provides a preparation method of the above flux paste. The flux paste provided by the invention improves the film-removing ability of the flux, improves the fluidity and activity of the flux, accelerates the removal of the oxide film and the spreading of the solder, and simultaneously protects the workpiece metal at high temperature and the molten state. The solder is protected from oxidation. |
