摘要: 采用锡氟磷酸盐玻璃(TFP)粉末与PA66(PA66)粉末混合、熔融共混和注塑成型制备了PA66/TFP杂化材料,并研究了不同TFP含量杂化材料的动态力学行为、结晶性能等。结果表明,当TFP填充量为30 %时,PA66的玻璃化转变温度(Tg)降低了13 ℃,且在130 ℃处出现了第三个松弛峰;加入TFP未改变PA66的晶型,却使得PA66的α晶型与γ晶型数量、结晶速度和结晶度明显降低;TFP颗粒形态可变,与PA66相容性良好且以两种尺寸的颗粒均匀分布。

Abstract: The PA66/tin fluorophosphate glass (TFP) hybrids were prepared via powder-mixing, melt-blending, and injection molding. The dynamic mechanical properties, crystallinity and morphology of hybrids were investigated. When 30 % TFP was loaded, the Tg of PA66 decreased by 13℃. The addition of TFP led to decreases the contents crystallizing rates of α and γ crystal forms of PA66. TEP was finely dispersed in PA66 matrix and exhibited good compatibility with the matrix.
