Title: Hydrogel water-retaining agent with ultra-high water absorption rate based on pulping waste liquid and preparation method thereof
Inventor: JIAN DU
IPC: C08F220/06
Filed: 2022-02-14
Granted: 2023-08-18
Abstract: Disclosed are a hydrogel water—retaining agent with an ultra—high water absorption rate based on pulping waste liquid and a preparation method thereof, belonging to the application fields of biomass energy and materials and biomass refining. The hydrogel water—retaining agent is prepared from pulping waste liquid, an acrylic monomer, a cross—linking agent and an initiator, wherein the pulping waste liquid and acrylic acid are mixed at a certain ratio, and the cross—linking agent and the initiator are used for adjusting the network structure of the hydrogel, so that the formed hydrogel has an ultra—high water absorption rate and excellent water retention performance, and obtains the advantages of high water absorption and high water retention. The waste liquid in a pulp and paper mill, which mainly contains hemicellulose and lignin, is directly mixed with the acrylic acid to prepare a hydrogel without separation and purification, so that the hydrogel in this method, features excellent biocompatibility and degradability, and can be used to retain water for vegetation in arid areas. Furthermore, the price of the hydrogel prepared by this method is extremely low.
