通过原位乳液插层法制备高有机蒙脱土(OMMT)含量的聚丙烯酸丁酯/有机蒙脱土(PBA/OMMT)纳米复合物,将其作为母料与ABS进一步熔融插层制得力学性能良好的ABS/OMMT纳米复合材料,并通过XRD、TGA和TEM等对材料进行了表征。结果表明:制得的PBA/OMMT母料为插层型纳米复合物,OMMT片层间距从2.38nm增大到3.85nm;采用母料法制备ABS/OMMT纳米复合材料,ABS链段易插层进入OMMT层间,使OMMT片层在ABS基体中达到剥离并以纳米尺度均匀分散,较好地保持了ABS的缺口冲击强度。
The in-situ emulsion intercalation method was used to prepare the polybutyl acrylate / organomontmorillonite (PBA / OMMT) nanocomposite with high content of OMMT, which was further melted and intercalated into ABS The performance of ABS / OMMT nanocomposites was characterized by XRD, TGA and TEM. The results show that the obtained PBA / OMMT masterbatch is an intercalated nanocomposite, the spacing of OMMT lamellae is increased from 2.38nm to 3.85nm, and the ABS / OMMT nanocomposites are prepared by the masterbatch method. The ABS segment is easily intercalated Into the OMMT layer, the OMMT sheet in the ABS matrix to achieve stripping and nano-scale uniform dispersion, better to maintain the notched Izod impact strength.
