Abstract: The present invention relates to the field of reutilization of biomass resources, and more particularly relates to a grafting method for rice straw fiber modification. The pulverized and pretreated straw powder is first reacted with diisocyanate under ultrasonic and microwave treatment, and the resulting product is reacted with PEG to obtain the PEG grafted straw fiber polymer compound. Grafting PEG onto the straw fiber through the bridging of the diisocyanate improves the thermoplasticity of the modified rice straw fiber. The modified straw fiber of the present invention can be hot-pressed to form self-reinforced composite materials without adding additional materials, which overcomes the waste and pollution problem of traditional straw reutilization method, achieving the goal of whole straw utilization.
