摘要
研究受阻酚AO-60用量对受阻酚AO-60/天然橡胶(NR)复合材料的结构与阻尼性能的影响。结果表明:受阻酚AO-60用量小于50份时,受阻酚AO-60在复合材料中主要形成小型聚集体;随着受阻酚AO-60用量的增大,受阻酚AO-60在复合材料中形成越来越多的大型聚集体;在差示扫描量热分析中,受阻酚AO-60在48和107℃时分别发生无定形态以及晶态转变;在室温下,受阻酚AO-60用量不小于50份的复合材料的损耗因子(tanδ)达到0.2以上,而不加受阻酚AO-60的NR胶料的tanδ仅为0.05;随着受阻酚AO-60用量的增大,复合材料的F_(max)-FL减小,t_(10)和t_(90)明显延长,拉伸强度和撕裂强度减小,受阻酚AO-60用量为50份的复合材料的回弹值最小。综合来看,受阻酚AO-60用量为50份的受阻酚AO-60/NR复合材料的性能最佳。
The effects of hindered phenol AO-60 amounts on the structures and damping properties of hindered phenol AO-60/natural rubber(NR)composites were studied.The results showed that,when the hindered phenol AO-60 amount was no more than 50 phr,the hindered phenol AO-60 formed small aggregates in the composites.As the hindered phenol AO-60 amount increased,more and more large aggregates of the hindered phenol AO-60 formed in the composites.In differential scanning calorimetry analysis,the hindered phenol AO-60 underwent amorphous and crystalline transitions at 48 and 107℃,respectively.At room temperature,the loss factor(tanδ)of the composites with no more than 50 phr hindered phenol AO-60 reached 0.2 or more,while the tanδof NR compound without hindered phenol AO-60 was only 0.05.As the hindered phenol AO-60 amount increased,the F_(max)-FL of the composites decreased,the t10 and t_(90)were significantly prolonged,the tensile strength and tear strength decreased,and the rebound value of the composite with 50 phr hindered phenol AO-60 was the smallest.Overall,when the hindered phenol AO-60 amount was 50 phr,the hindered phenol AO-60/NR composite had the best properties.
