| titleOfInvention | A kind of preparation method of sheet stiffness agent |
| abstract | A preparation method for sheet stiffness agent, (1), with molar percent, gets the acrylamide monomer of 75 ~ 98%, the water-soluble cationic monomer of 0.5 ~ 15%, the non-ionic monomer of 1 ~ 15% and the sequestrant of 0.05 ~ 5%, be added to the water under agitation condition, be mixed with mixed aqueous solution; (2) aqueous solution pH is regulated? 5.0 ~ 7.0, under logical nitrogen protection, add initiator in early stage, be warming up to 40 ~ 70 DEG C, carry out polyreaction 30 ~ 90min? (3) add later stage initiator in the product of step (2), then drip linking agent, 50 ~ 70 DEG C keep 30 ~ 60min after add terminator, stop polyreaction.Sheet stiffness agent of the present invention, it is characterized in that polymerization process is stablized controlled, product crosslinking degree is high, and binding site is many, good fluidity, is conducive to eliminating the interference of plain boiled water intermediate ion rubbish under high conductance condition and catches fiber fines. |
