| titleOfInvention | A kind of zinc anticorrosion electrolytic phosphating solution and preparation method thereof |
| abstract | The invention discloses a zinc-based anti-corrosion electrolytic phosphating solution and a preparation method thereof; in parts by mass, its raw material formula components include: Zn 2+ 1-10 parts; PO 4 3-10-50 parts; functionalized 0.01-1 part of graphene oxide; 5-15 parts of pH regulator; 1000 parts of water. Preparation of functionalized graphene oxide: disperse graphene oxide in absolute ethanol, react with silane coupling agent at elevated temperature and reflux, and disperse in deionized water after suction filtration and washing to obtain a dispersion; the resulting dispersion, cationic monomer, The initiator and deionized water are put into the reaction kettle, the temperature is raised to react, and after suction filtration and washing, the product is dispersed in deionized water to obtain the product. The electrolytic phosphating solution prepared by the present invention can solve the dispersibility problem of graphene oxide in the electrolytic phosphating solution well without using surfactants and stabilizers, and the preparation process of the electrolytic phosphating solution is non-toxic and harmless, and the process Simple, convenient and controllable, and beneficial to realize industrialization. |
