| titleOfInvention | A kind of high-strength fully degradable lignin-based superabsorbent resin and preparation method thereof |
| abstract | The invention relates to the technical field of superabsorbent resins, aiming at the problems of low degradability of superabsorbent resins and poor mechanical strength after water absorption, and discloses a high-strength fully degradable lignin-based superabsorbent resin, which is composed of 100 parts by weight of lignin compounds. , 5-20 parts of hyperbranched cross-linking agent, 0.01-0.1 part of surfactant, 2.0-5.0 parts of primary surface treatment agent, 4-6 parts of secondary surface treatment agent, hyperbranched cross-linking agent is made of polyether structure The main chain is an aldehyde end group hyperbranched crosslinking agent, a carboxyl end group hyperbranched crosslinking agent, an amine end group hyperbranched crosslinking agent and an epoxy end group hyperbranched crosslinking agent. The resin prepared by the invention shows a high swelling rate in both pure water and physiological saline, and at the same time, the resin still has high toughness and strength after absorbing water, and has excellent degradation performance. The experimental conditions at the bottom of the simulated landfill The degradation rate can reach more than 80% in the next 90 days, and the degradation rate can reach more than 95% in 270 days. |
