摘要
通过对聚氨酯(PUR)弹性体/超细滑石粉复合材料进行X射线衍射、红外光谱和热重分析,研究了该复合材料的结构及性能。结果表明,在PUR弹性体中添加适量(质量分数15%左右)的超细滑石粉,可使滑石粉与PUR弹性体相互融合,形成了异相成核的复合结构,从而使PUR弹性体中的软段、硬段、滑石粉颗粒形成相互作用的聚集体系,提高了PUR弹性体的综合力学性能及热稳定性。
The structure and performance of polyurethane elastomer/superfine talcum powder composites were investigated by X ray diffraction （XRD）, FTIR spectra and thermo gravimetric analysis （TG - DTA,DSC）. The results showed that talcum powder and polyurethane elastomer formed compound structure of heterogeneous nucleation when the content of superfine talcum powder was right（ such as 15% ）, which caused the soft segments, hard segments and talcum powder of polyurethane elastomer to form interactional congeries system and the integrated mechanical properties and thermostability of polyurethane elastomer were improved.
