Abstract:The invention provides a chlorinated poly(propylene carbonate)/biomass composite material, which comprises the following components by weight percentage: 3wt%–57wt% of chlorinated poly(propylene carbonate); 40wt%–94wt% of biomass material; 2wt%–20wt% of rosin or rosin derivative; 0wt%–1wt% of antioxidant; and 0wt%–5wt% of filler, with the sum of the weight percentages of all components being 100%.Chlorinated poly(propylene carbonate) serves as a binder, endowing the composite material with thermoplasticity and fluidity, and also plays a vital role in improving the moisture resistance of the composite material. Rosin or rosin derivative acts as a tackifier and lubricant, which can further enhance the moisture resistance and mechanical properties of the composite material.Under the synergistic effect of the above components, the prepared composite material exhibits excellent mechanical properties and moisture resistance. In addition, the composite material has a high proportion of biomass material, which contributes to low production cost. Moreover, no formaldehyde, benzene or other toxic substances are involved in the raw materials, leading to excellent environmental friendliness.
