Abstract

An analysis of the effect of dispersion of powders of zinc oxide, metallic zinc, and iron on the inelasticity of the polymer composition was carried out by comparing the temperature–frequency dependences and spectra of internal friction in the region of the glass-transition temperature corresponding to the occurrence of the α-relaxation process. The correlation of the internal friction spectra with the nature of the temperature–frequency dependences obtained using the method of dynamic mechanical relaxation spectroscopy was established. On the basis of experimental data, the regions of inelasticity of the polymer are established and compared, which indicate its decrease with an increase in the dispersion of the filler. The latter can be accompanied by disruption of intermolecular bonds in the polymer and the formation of new relaxation structures in the presence of a filler.

金属和含金属填料的分散对复合聚合物非弹性的影响

摘要

通过比较温度-频率依赖性和在相应的玻璃化转变温度区域内的内摩擦光谱，分析了氧化锌、金属锌和铁粉末的分散对聚合物组合物非弹性的影响。 α-弛豫过程的发生。建立了内摩擦光谱与使用动态机械弛豫光谱方法获得的温度-频率依赖性的性质的相关性。在实验数据的基础上，建立并比较了聚合物的非弹性区域，这表明它随着填料分散度的增加而减小。
