| 摘 要： | 用差示扫描量热法、X射线衍射法、扫描电子显微镜及元素分析法分析了丁腈橡胶(NBR)/聚氯乙烯(PVC)/四β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯(AO-60)共混物的结构,并研究了共混物的阻尼性能及力学性能。结果表明,当AO-60用量小于50份时,其分子在基体中以非晶态形式存在;当AO-60用量超过50份时,过量的AO-60形成聚集体并在基体中形成少量的晶体;NBR/PVC/AO-60共混物内部呈现“海相-岛相”结构,连续相主要是NBR,而分散相主要是PVC与AO-60分子。NBR/PVC/AO-60共混物的损耗因子-温度曲线呈双峰特征,且随着AO-60用量的增加,峰值明显增大。当AO-60用量为50份时,NBR/PVC/AO-60共混物的综合力学性能较佳。

| Abstract: | The structure of acrylonitrile-butadiene rubber/poly(vinyl chloride)/hindered phenol tetrakismethylene-3-(3,5-ditert butyl-4-hydroxy phenyl) propionyloxy]methane(NBR/PVC/AO-60) blends was characterized by differential scanning calorimetry, X-ray diffraction, scanning electron microscope and elemental analysis. Damping properties and mechanical properties were studied. The results showed that most of the AO-60 molecules was amorphous in the blend when the amount of AO-60 was lower than 50 phr. AO-60 molecules could form crystal in the matrix with adding overdose of AO-60. The island phase mostly composed of PVC and AO-60 molecules, the continuous phase was mostly consisted of NBR. Doublet transition of the NBR /PVC /AO-60 blends appeared above the glass transition temperature of the NBR/PVC matrix and it increased as increasing amount of AO-60. The mechanical properties of NBR /PVC /AO-60 blends was better with adding 50 phr of AO-60. |
