CHLORINATED POLY(PROPYLENE CARBONATE)/BIOMASS COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR

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.

本发明提供一种氯化聚碳酸亚丙酯（chlorinated poly(propylene carbonate)）/生物质复合材料，其组成包括3 wt%至57 wt%的氯化聚碳酸亚丙酯、40 wt%至94 wt%的生物质材料、2 wt%至20 wt%的松香或松香衍生物、0 wt%至1 wt%的抗氧剂，以及0 wt%至5 wt%的填料，且所有组分的总质量占比为100 wt%。其中，氯化聚碳酸亚丙酯作为粘结剂，对该复合材料的耐湿性具有关键作用；松香或松香衍生物兼具增粘剂与润滑剂的功能，同时可改善复合材料的耐湿性与力学性能。在上述组分的协同作用下，本发明制备得到的复合材料兼具优异的力学性能与耐湿性。此外，由于原料中含有大量生物质材料，该复合材料的成本较低；且原料不含甲醛、苯等有害物质，具备环境友好特性。
