Abstract

The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, comprising 3 wt % to 57 wt % of a chlorinated poly(propylene carbonate); 40 wt % to 94 wt % of a biomaterial; 2 wt % to 20 wt % of a rosin or a rosin derivative; 0 wt % to 1 wt % of an antioxidant; and 0 wt % to 5 wt % of a filler, wherein a sum of amounts of all components is 100 wt %. The chlorinated poly(propylene carbonate) functions as a binder, and plays an important role in the moisture resistance of the composite material. The rosin or the rosin derivative functions as a viscosifier and a lubricant, and can also improve the moisture resistance and mechanical property of the composite material. Under the synergistic effect of the above components, the composite material obtained in the present invention is excellent in both mechanical property and moisture resistance. Further, because the starting materials comprise a larger amount of biomass materials, the cost thereof is low, and because the starting materials contain no formaldehyde, benzene and the like, the material is environment friendly.
