| 摘 要： | 本文研究了单一和混合偶联剂表面改性的柠檬石膏对柠檬石膏/聚丙烯复合材料的力学性能,结晶度,熔点的影响;结果表明:单一偶联剂表面改性的柠檬石膏使柠檬石膏/PP复合材料的拉伸强度,弯曲强度和弯曲模量较PP有不同程度提高,钛酸酯和铝酸酯偶联剂对柠檬石膏的表面改性具有较好效果。混合偶联剂表面改性的柠檬石膏使柠檬石膏/PP复合材料的冲击强度较单一偶联剂表面改性柠檬石膏填充PP的复合材料提高了34.7%,而拉伸强度,弯曲强度和弯曲模量均有一定下降。差示扫描量热(DSC)分析结果显示柠檬石膏的加入可以提高聚丙烯的结晶度,对复合材料的熔点几乎没有影响;柠檬石膏的表面改性对复合材料中PP的结晶度和熔点均没有明显影响。
