| titleOfInvention | A kind of nonionic and the mixed and modified water-based polyurethane curing agent of anion and preparation method thereof |
| abstract | The invention discloses a kind of nonionics and the mixed and modified water-based polyurethane curing agent of anion and preparation method thereof.This method is under nitrogen protection, oligomer polyol to be added into HDI monomers, stirs and is heated to 60 ~ 80 DEG C and keeps the temperature, and reacts 2 ~ 3 hours, obtains addition product；Catalyst for trimerization is added into gained addition product, the insulation reaction at 60 ~ 80 DEG C under conditions of 150 ~ 180 DEG C, 0.01 ~ 0.05Torr, the complete HDI monomers of unreacted is removed, HDI prepolymers are obtained when NCO content reaches desired value；It waits for that gained HDI prepolymers cool to 60 ~ 70 DEG C, is added anion-modified dose, and insulation reaction 2 ~ 4 hours, add neutralizer, after reaction 0.5 ~ 1 hour, cooling discharge obtains water-based polyurethane curing agent.The preparation method of the present invention is simple；Gained water-based polyurethane curing agent is of light color, effective NCO content height, color inhibition, storage stability are good. |
