| titleOfInvention | A kind of method adopting inverse emulsion polymerization to prepare amphoteric dry strength agent |
| abstract | The invention discloses a method for preparing an amphoteric dry strength agent by reverse-phase emulsion polymerization, which comprises steps: step 1, mixing an oil solvent and an emulsifier to obtain a mixed solution A; step 2, mixing acrylamide, anionic monomer, cationic Monomer, functional monomer, reaction inhibitor, crosslinking agent, disodium edetate and water are mixed to obtain mixed solution B; step 3, mixed solution B is added to mixed solution A, and emulsified to obtain stable emulsion C ; Step 4, add an initiator to the stable emulsion C to carry out inverse emulsion polymerization, and obtain an amphoteric dry strength agent after the reaction is completed. The amphoteric dry strength agent prepared by the method of the present invention has the characteristics of low viscosity, good heat dissipation, fast reaction, and narrow molecular weight distribution of the product, and can greatly improve the tensile strength and internal bonding strength of paper, and at the same time, its ring compressive strength and bursting index are significantly improved. ; In addition, the use of inverse emulsion polymerization technology effectively reduces the exothermic temperature rise during the reaction process and greatly reduces the gel point. |
