| 摘 要： | 采用自制的丙烯酸十八酯一马来酸酐共聚物作为相容剂，以聚丙烯为基材，通过填充淀粉和CaCO3以及加入光敏剂，用机械熔融共混的方法制成了可生物降解和光降解的复合物，并用红外光谱对复合物进行了表征．对该复合物的力学性能、热性能和耐老化性能等进行了测试分析。结果表明，加入填料后，复合物的力学性能下降．淀粉和CaCO3总质量分数不宜超过60％；复合物的熔点随填料量的增加而降低；加入光敏剂起到了预想光降解的效果。

| Abstract: | Biodegradable and photodegradable composites were prepared in the method of melt blending with taking homemade octadecyl acrylate-maleic anhydride copolymer as compatibilizer, polypropylene as basic resin, starch and calcium carbonate as filler and adding photosensitizer. The composites were characterized by infrared spectrometry) ant its mechanical properties, thermal properties and aging resistance were tested. The results show that the mechanical properties decrease after adding the filler. The mass fraction of starch shall not exceed 30% and the mass fraction of shall not exceed 60%. The melt point of the composites goes down as the filler content increases. The addition of the photosensitizer brings about the expected photodegradative effectiveness. |
