| titleOfInvention | The plain tin cream scaling powder of water-soluble lead-free and halogen-free and preparation method |
| abstract | The present invention relates to a kind of plain tin cream scaling powder of water-soluble lead-free and halogen-free and preparation method, it is made up of the raw material of following weight percentage：Anhydrous citric acid 10 15%, glutaric acid 6 10%, malic acid 1 3%, cetomacrogol 1000 8 12%, glycerine 60 65%, triethanolamine 1 3%, the octyl phenyl ether 1 5% of polyoxyethylene 8, suitable for the technological requirement of unleaded washing tin cream, welding assisted agent residuals are water-soluble after welding and do not contain halogen, Environmental Safety；The tin cream of preparation has that viscosity is good, and storage life limit for length, solder joint is full, and brightness is moderate, is to contain halogen in traditional scaling powder the problem of solution, harmful substance can be produced in heating process；On the other hand, cleaning is solved with water come instead of harm of the poisonous and harmful cleaning agent to human and environment such as dichloromethane, trichloroethanes. |
