Abstract：The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, which comprises 3 wt% to 57 wt% of chlorinated poly(propylene carbonate), 40 wt% to 94 wt% of biomaterial, 2 wt% to 20 wt% of rosin or a rosin derivative, 0 wt% to 1 wt% of an antioxidant, and 0 wt% to 5 wt%, with the total content of all components being 100 wt%. The chlorinated poly(propylene carbonate) acts as a binder, endowing the composite material with heat shrinkage and flowability, and also plays a crucial role in the moisture resistance of the composite material. The rosin or rosin derivative serves as a tackifier and lubricant, and can also improve the moisture resistance and mechanical properties of the composite material. Under the synergistic effect of the above components, the composite material obtained by the present invention exhibits excellent mechanical properties and moisture resistance. In addition, the composite material contains a large proportion of biomass material, resulting in low cost; moreover, no formaldehyde, benzene or other harmful substances are used in the raw materials, leading to excellent environmental friendliness.
