| 摘 要： | 采用十二烷基三甲基溴化铵（DTAB）对累托石（REC）进行有机处理制备出有机改性累托石（OREC），通过熔融插层法制备出了乙烯-醋酸乙烯共聚物/有机改性累托石（EVA/OREC）复合泡沫材料。利用傅里叶红外光谱仪（FTIR）、X射线衍射仪（XRD）、扫描电子显微镜（SEM）、万能试验机等对复合材料的形貌和力学性能进行了表征，研究了累托石的层间距、含量对复合泡沫材料力学性能的影响。结果表明，经有机改性后累托石层间距增加了10.9 %；复合材料的拉伸强度、断裂伸长率、撕裂强度也随之明显升高；且当OREC质量组分为10份时材料的各项力学性能达到最佳。

| Abstract: | The organic modified rectorite (OREC) was prepared with dodecyl trimethyl ammonium bromide, and then the EVA/OREC composite foaming materials were prepared by a melting intercalation technology. The morphology and mechanical properties of the composites were investigated by FTIR spectroscopy, X-Ray diffraction, scanning electron microscopy and universal testing machine. The effects of interlayer spacing and content of rectorite on the mechanical properties of the composite were investigated. The results indicated that the interlayer spacing of rectorite increased by 10.9 % after organic modification, and the tensile strength, elongation at break, tear strength of the composite foaming materials were enhanced significantly. The composite foaming materials achieved the optimum mechanical properties at the OREC content of 1.8 %. |
