Abstract: In this study, Cinnamomum longipaniculatum leaf residue was used as the main raw material, and the parameters such as adhesion, cracking, mildew growth and drop resistance were taken as evaluation indicators. Parameters such as particle size, binder and drying temperature of different C. longepaniculatum stalks were optimized to screen the preparation technology of biomass materials. The results showed that the biomass materials made by using high gluten flour as binder and mixing with coarser oil eucalyptus powder (the powder remaining over the 1 mm sieve) and drying at 25 ℃ had the best performance.
