A degradable CMC/BP water-absorbing resin was prepared using carboxymethyl cellulose(CMC)and bamboo powder(BP)as the main raw materials,and polyethylene glycol diglycidyl ether(PEGDE)as the crosslinking agent.The effects of BP dosage,crosslinking agent dosage,and reaction temperature on the performance of CMC/BP water-absorbing resin were investigated.The microstructure and morphology of the CMC/BP water-absorbing resin were characterized by X-ray diffractometer,Fourier transforms infrared spectrometer and scanning electron microscope,and its water absorption and water retention properties were tested.The results showed that when the CMC dosage was 4g,the BP dosage was 5g,the PEGDE dosage was 13mL,and the reaction temperature was 60℃,the prepared CMC/BP water-absorbing resin had a water absorption rate of 21.1g/g,and a water retention rate of 55％after 120 hours of water absorption,achieving the best water absorption and water retention properties.
