| 摘 要： | 以PA6为基体、废旧轮胎粉与POE-g-MAH为复合增韧剂,采用双螺杆挤出机,制备了废旧轮胎粉/POE-g-MAH/PA6复合材料,研究了复合增韧剂含量对复合材料力学性能、熔融与结晶行为、晶体结构、热性能以及微观形貌等的影响.结果表明,复合材料的冲击强度和断裂伸长率随复合增韧剂含量的增加而显著提高,而拉伸强度和弯曲强度则正好相反;DSC、XRD和TGA结果表明,复合增韧剂的加入,提高了PA6基体的结晶速率,却降低了其结晶度、晶体结构的完整性和耐热性能.

| Abstract: | The composites of wasted tire powder/POE-g-MAH/PA6 were prepared based on PA6, wasted tire powder and POE-g-MAH by using twin screw extruder. The effect of elasticizer contents on mechanical properties, melting and crystallization behavior, crystal structure, thermal properties and microstructure of composites were studied. The results showed that the impact strength and elongation at break were significantly increased with increasing contents of the elasticizers, whereas it was contrary for the tensile strength and flexural strength. The DSC, XRD and TGA results showed that the PA6 matrix crystallization rate were increased, while crystallinity, crystal structure integrity and heat resistance were reduced with the addition of elasticizers. |
