| titleOfInvention | A kind of technique that continuity method prepares aqueous polyurethane optical coating |
| abstract | The invention discloses the techniques that a kind of continuity method prepares aqueous polyurethane optical coating.The technique includes：1) diisocyanate, organo-metallic catalyst and hydrophilic chain extender/polytetrahydrofuran ether glycol solution are continuously passed through the first prepolymerization kettle and carry out one-step polymerization；It is passed through the second prepolymerization kettle again and carries out two sections of polymerizations.2) obtain two sections of polymer materials and tertiary amines neutralizer are continuously passed through the first static mixer neutralization reaction and generate waterborne polyurethane prepolymer.3) prepolymer is passed through the first high speed shear mixing emulsifier, and chain extending reaction occurs while emulsification in the aqueous solution containing sulfonate type chain extender；It is sent into the second high speed shear mixing emulsifier, the continuous hydrazine hydrate rear chain extender that is added dropwise obtains aqueous polyurethane emulsion.4) aqueous polyurethane emulsion is continuously mixed with deionized water in the second static mixer；It is passed through paint mixing kettle and starches mixing with adjuvant pigments.Compared with prior art, the present invention is with product preparation process is simple, stability is good, high-efficiency and economic feature. |
