| titleOfInvention | Preparation method of acid-resistant poly (amide-triazine-amine) nanofiltration composite membrane |
| abstract | The invention discloses a preparation method of an acid-resistant poly (amide-triazine-amine) nanofiltration composite membrane, which comprises the following steps of firstly, taking cyanuric chloride and polyamine as raw materials, and preparing a poly (triazine) amine precursor through nucleophilic substitution reaction; and respectively preparing water phase reaction liquid of a poly (triazine) amine precursor and polybasic acyl chloride oil phase reaction liquid, and preparing the acid-resistant poly (amide-triazine-amine) nanofiltration composite membrane on the support membrane through interfacial polymerization. The invention provides a preparation method of an acid-resistant poly (amide-triazine-amine) nanofiltration composite membrane, which can effectively improve the poor separation performance of a poly (triazine) amine sodium filtration composite membrane and avoid the defect that an interfacial polymerization water-phase monomer is limited in linear multi-active amines. The membrane is suitable for a salt-water separation system, and has good separation performance and good acid resistance. |
