Abstract: The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, comprising: 3 wt% to 57 wt% chlorinated poly(propylene carbonate), 40 wt% to 94 wt% biomass material, 2 wt% to 20 wt% rosin or rosin derivative, 0 wt% to 1 wt% antioxidant, and 0 wt% to 5 wt% filler, where the sum of the amounts of all components totals 100 wt%.Chlorinated poly(propylene carbonate) acts as a binder, imparts thermal shrinkage property and flowability to the composite material, and also plays a vital role in improving the moisture resistance of the composite. Rosin or rosin derivatives function as tackifiers and lubricants, and can further enhance the moisture resistance and mechanical properties of the composite material.Through the synergistic effect of the above components, the composite material prepared by the present invention achieves excellent mechanical properties and superior moisture resistance. Furthermore, the composite material contains a high proportion of biomass materials, which lowers production costs. No formaldehyde, benzene or similar substances are used in the raw material system, rendering the product environmentally friendly.
