【摘要】 以受阻酚AO-60为填充材料,考察了其用量对氯化聚乙烯(CM)弹性体/受阻酚复合材料耐老化性能、硫化特性、力学性能和分散性的影响。结果表明,随着受阻酚AO-60用量的增加,复合材料的耐老化性能变好,拉断伸长率降低。当AO-60用量为30份时,拉伸强度为16.7MPa;撕裂强度为38.5kN/m。由炭黑分散度测定仪观察,AO-60用量在30份以下时,分布效果较好;AO-60用量在50份以上时,与CM基体出现相分离。综合考虑,AO-60用量为30份时为宜。更多还原

【Abstract】 The effect of hindered phenol AO-60content,as a filler,on the aging resistance,cure characteristic,mechanical properties and its dispersion in the composites of hindered phenol AO-60 and chlorinated polyethylene were studied.The results showed that with loading of hindered phenol AO-60increased,the aging resistance were enhanced,the elongation at break was decreased.When the hindered phenol AO-60was 30phr,the tensile strength and tear strength appeared maximum value(16.7MPa,38.5kN/m).It showed that the suitable loading of hindered phenol AO-60was 30phr.更多还原
