摘　　要：为提高丁腈橡胶的力学性能,采用共固化的方法制备癸二胺型苯并噁嗪树脂(Bz)改性的丙烯腈-丁二烯橡胶(NBR)复合材料NBR-Bz,着重研究NBR-Bz橡胶同未改性的NBR在机械性能方面的差异.研究结果表明:与完全用硫磺硫化的NBR相比,NBR-Bz橡胶的拉伸强度、断裂伸长率明显增加;添加5 g的Bz可以使拉伸强度增加68%,断裂伸长率增加66%.这说明癸二胺型苯并噁嗪树脂具有明显的增强和增韧作用.To improve the mechanical properties of nitrile rubber,a co-curing method was used to prepare acrylonitrile butadiene rubber(NBR)composite material NBR-Bz modified with decanediamine benzoxazine resin(Bz).The difference in mechanical properties between NBR-Bz rubber and unmodified NBR.were studied.The test results showed that the tensile strength and elongation at break of NBR-Bz rubber were significantly increased compared with unmodified NBR.The addition of 5 g Bz can increase the tensile strength by 68%and fracture elongation by 66%.This indicates that the decanediamine benzoxazine resin has a significant strengthening and toughening effect.
