应用
Application |
受阻酚类添加剂 NQX80 对 NRBR 并用胶性能影响的实显示其对硫化特性、力学性能老化特性以
及动态力学性能的影响如下：
(1)受阻酚的加入会使得NR/BR并用胶的t10和t90增大MH减减小,模量下降,MHML的值减小,
材料的交联度降低。
(2) 会使得井用胶硬度和回弹性下降 ,100% 定伸应力和拉断伸长率先略微增加然后减小 , 拉伸强
度和撕裂强度下降。
(3)100℃热空气老化 24h 后 , 加入受阻酚的胶料拉伸强度保持率和拉断伸长保持率都有一定程度
提高 , 耐热空气老化性能改善。
(4) 还使得胶料玻璃化转变区 tan5 减小 ,0℃以上加 , 材料阻尼性能得至改善。
The experiment of effects of hindered phenol additives NOX-80 on the vulcanization properties shows that:
·After the addition off hindered phenol,the t10 and t90 of the blend was increased,ML changed a little,MH
decreased,indicating that the modulus of blends decreased;
·The hardness and elasticity decreased,100% tensile stress and tensile elongation increased slightly and then
dereased,tensile strength and tear strength decreased;
·After 100℃ hot air aging 24h,the retention rate of tensile strength and elongation at break rate
improved,the property of hot air aging improved;
·In the zone of glass transition,tan5 increased;in the temperature range of 0℃ -80℃ ,damping
performance improved. |
