恒粘改性天然橡胶杯凝胶在V带底胶中的应用
|
摘要
用恒粘剂盐酸羟胺(HH)对天然橡胶(NR)杯凝胶进行恒粘改性,研究HH质量分数对NR性能的影响,并探究恒粘NR在V带底胶中的应用性能。结果表明:通过改变HH质量分数可以制备门尼粘度不同的恒粘NR;HH改性的恒粘NR生胶的弹性模量减小,损耗因子增大;恒粘NR制备的V带底胶不仅加工性能改善,硫化速率增大,密炼能耗降低,生产效率提高,而且物理性能、耐屈挠性能和炭黑分散性提高;用质量分数为0.005的HH改性的恒粘NR制备的V带底胶拉伸强度最高,耐屈挠性能最好。
Constant viscosity modification of natural rubber(NR) cup lump with viscosity stabilizer hydroxylamine hydrochloride(HH) was investigated. The effect of HH mass fraction on NR performance and the application of constant viscosity NR in V-belt base rubber were studied. The results showed that,the constant viscosity NR with different Mooney viscosity could be prepared by changing the HH mass fraction.The elastic modulus of constant viscosity raw NR modified by HH decreased,and the loss factor increased. The processability of the V-belt base rubber prepared by constant viscosity NR modified by HH was improved,the vulcanization speed increased,mixing energy consumption was reduced,production efficiency was improved,and the physical properties,flexing resistance and carbon black dispersion were improved. The V-belt base rubber with constant viscosity NR modified by HH with the mass fraction of 0.005 had the highest tensile strength and the best flexing resistance.
