| titleOfInvention | The method that uv-light polymerization prepares drying strengthening agent |
| abstract | The invention provides a kind of method that uv-light polymerization prepares drying strengthening agent, comprise the following steps：Cationic starch and water are mixed, Heat Gelatinization, water, acrylamide, cross-linkable monomer, chain-transferring agent, other functional monomers and photoinitiator are sequentially added, under oxygen-free environment, temperature is risen to 70 95 DEG C, reaction system irradiating ultraviolet light is reacted 1.5 2 hours, sampling carries out viscosity test at regular intervals afterwards, and viscosity, which reaches, stops irradiating ultraviolet light after 4000 9000mP*s, adds pH adjusting agent regulation pH to 46, and free radical scavenger is added, obtain the drying strengthening agent.The drying strengthening agent synthesized with this method has the characteristics of consumption is few, effect is good, cost is low.It can be used in the production of a variety of paper kinds such as boxboard, fluting medium, art paper, cop tube paper, speciality paper, play a part of increasing paper dry strength, especially when with reclaimed waste paper slurry as paper making raw material, effect is more notable. |
