通过接枝反应制备BF-
g
-SMA相容剂
增容聚对苯二甲酸乙二醇酯/竹纤维(PET/BF)共混物
探究BF-
-SMA相容剂用量和PET/BF质量配比对PET/BF共混体系的影响
并通过红外光谱、扫描电镜及差示扫描量热仪及熔融指数仪器进行性能表征。结果显示
相容剂用量为6%和竹纤维用量为20%下
增容效果最好。此时
PET/BF共混物的熔融指数最大、密炼时扭矩最小
流动性最好;共混物的表面较光滑、竹纤维与聚合物基体的结合较好;熔融温度、结晶温度、结晶焓及结晶度较适宜。
BF-
-SMA compatibilizer was prepared by grafting reaction as the compatibilizer of PET/BF blends. The optimum of BF-
-SMA compatibilizer and PET/BF mass ratio (BF content) were investigated by FT-IR
SEM
DSC and Melting Index. The results show that the dosage of compatibility agent and bamboo fiber are 6% and 20%
respectively. There are the smallest torque
the largest melting index and the best fluidity in the PET/BF blends. In addition
the surface of the blends are better smooth with good phase interface for bamboo fiber and the polymer matrix. Other than
the melting temperature
crystallization temperature
crystallization enthalpy and crystallinity are also suitable.
