摘要
研究天然橡胶(NR)-伊/蒙粘土(YM)复合材料(简称NR-YM)的制备与性能。结果表明:与NR相比,NR-YM的灰分质量分数较大,挥发分和氮质量分数相近;与NR胶料相比,NR-YM胶料的交联密度增大,加工安全性能、300%定伸应力、拉伸强度、耐磨性能和耐热老化性能提高;随着YM用量增大,NR-YM胶料的拉伸强度、耐磨性能和耐热氧老化性能先提高后降低;当YM用量为8份时,NR-YM胶料的综合性能最好。
In this study,the preparation and properties of natural rubber（NR）-illite/montmorillonite clay（YM） composite（NR-YM）were introduced. The results showed that compared with NR,NR-YM had a higher ash content,similar volatile content and nitrogen content. Compared with NR compound,the crosslinking density of NR-YM compound was higher,the processing safety performance,modulus at 300% elongation,tensile strength,wear resistance and heat aging resistance were improved. With the increase of YM amount,the tensile strength,wear resistance and heat-oxygen aging resistance of NR-YM compound were firstly improved and then decreased. With 8 phr YM,the comprehensive properties of NR-YM compound were the best.
