摘要
在通常条件下多次加工CaCO3填充的丙烯腈-丁二烯-苯乙烯三元共聚物(ABS)复合材料,用傅里叶红外光谱(FTIR)和凝胶渗透色谱(GPC)研究ABS的降解情况,并测试了材料的冲击和拉伸性能。结果表明在多次加工中CaCO3含量低于10%时,ABS的橡胶相降解明显,复合材料的冲击性能明显下降;而CaCO3含量高于15%时,ABS的橡胶相降解不明显,复合材料的冲击性能基本不变。
In this study, Acrylonitrile-Butadiene-Styrene （ABS）/CaCO3 composites were reprocessed under normal conditions. The effects of reprocessing on the degradation of ABS were investigated by Fourier Transform Infrared Spectroscopy （FFIR） and Gel Permeation Chromatography （GPC）. The impact and tensile properties were measured. The results showed that during reprocessing, when the content of CaCO3 was lower than 10%, rubber phase of ABS had obviously degraded, and the impact strength of the composites had been significantly reduced. However, when the content of CaCO3 was higher than 15% , degradation of rubber phase was relatively small; the impact strength of composite was almost unchanged.
