| 摘 要： | 研究木粉用量、PP-g-MAH相容剂、WBG晶型改性剂，对再生聚丙烯／未粉复合材料性能和结构形态的影响。试验结果表明：PP-g-MAH能增加木塑复合材料的相容性，提高木塑复合材料的性能；适量木粉能提高复合材料的拉伸模量、弯曲性能和热变彤温度，但材料的冲击强度和断裂伸长率有所降低。添加WBG晶型改性剂，能改善复合材料的晶体结构，提高材料的塑性。

| Abstract: | Recycled polypropylene and wood powder were mixed together to make a composite. In this paper, the effects of the amount of wood powder, PP-g-MAH compatilizer and WBG crystalline phase modifier on the properties and morphologies of the composite were studied. The results indicated that PP-g-MAH compatilizer could improve the compatibility and properties of the composite. Suitable amount of wood powder was also helpful for the increase of composite tensile modulus, flexural property and heat distortion temperature, while it might decrease the impact strength and tensile elongation. The addition of WBG crystalline phase modifier improved the crystalline configuration and the plasticity of the composite. |
