Abstract
In order to improve the comprehensive performance of phenolic foam, 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) was grafted with itaconic acid (ITA) (DOPO-g-ITA) to modify microcrystalline cellulose (MCC). DOPO-g-ITA modified MCC (DIMMCC) was used to prepare composite phenolic foam (DCPF). The structures of DIMMCC were verified by Fourier transform infrared spectroscopy (FT-IR). The microstructure and crystalline property were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD) respectively. Compared with MCC, the crystallinity of DIMMCC was dramatically decreased, but the diffraction peak positions were unchanged. Thermal stability was decreased, and Ti decreased by 45.0°C. The residual carbon (600°C) was increased by 22.34%. With the dosage of DIMMCC/PR increased, compared with PF, the mechanical properties and flame retardancy of DCPF were increased. Especially, the dosage of DIMMCC/PR was 10%, the comprehensive properties of DCPF was better than others.
