| titleOfInvention | Method for preparing papermaking sizing emulsion based on cationic Janus particles |
| abstract | The invention discloses a method for preparing papermaking sizing emulsion based on cationic Janus particles, and belongs to the technical field of papermaking sizing. The method can solve the problems of poor emulsification effect and the like in the prior sizing emulsion prepared by using cationic starch, Pickering particles and the like. The preparation method comprises the steps of firstly preparing seed emulsion with stable starch, then adding cationic monomer and cationic initiator to prepare cationic Janus particles, then mixing the cationic Janus particles with sizing agent, and fully emulsifying to obtain the papermaking sizing emulsion. When the preparation method of the sizing emulsion provided by the invention is used for papermaking sizing, the stability and sizing effect can be improved, the cationic Janus particles can be adsorbed on the surface of fibers with negative electricity, the utilization rate of the Janus particles is improved, and the sizing efficiency is obviously improved compared with the sizing emulsion prepared by adopting cationic starch or Pickering particles. |
