摘　　要：研究了混炼工艺对氢化丁腈橡胶复合材料性能的影响。结果表明,随着填充系数提高,胶料的生产效率提升,但混炼安全性降低;填料分散性提升,混炼胶门尼黏度呈降低趋势,硫化性能相差不大;硫化胶硬度呈减小趋势,耐压缩永久变形性能提升,填充系数对力学强度、拉断伸长率和耐老化性能影响不大。随着密炼转速增大,混炼功率消耗增大,混炼安全性降低,填料分散性提升,混炼胶门尼黏度和硫化性能相差不大;硫化胶硬度呈减小趋势,耐压缩永久变形性能提升,转速对力学强度、拉断伸长率和耐老化性能影响不大。随着初始温度升高,混炼功率消耗降低,但混炼安全性下降,初始温度对混炼胶及硫化胶性能影响不大。The effect of mixing process on the properties of hydrogenated nitrile butadiene rubber(HNBR)was studied.The results showed that,with the increase of filling factor,the production efficiency of the rubber material was improved,but the mixing safety was reduced;the filler dispersion improved,and the Mooney viscosity of the mixing compound tended to decrease,and the vulcanization performance was not much different;the hardness of the vulcanizates tended to decrease,and the resistance to compression and permanent deformation was improved,and the filling factor had little effect on the mechanical strength,elongation at pull-off and aging resistance.With the increase of mixing speed,mixing power consumption increased,mixing safety decreased,filler dispersion improved,mixing rubber Mooney viscosity and vulcanization performance did not differ much;vulcanizates hardness tended to decrease,compression permanent deformation resistance improved,and the speed had little effect on the mechanical strength,elongation and aging resistance.As the initial temperature increased,the mixing power consumption decreased,but the mixing safety decreased,and the initial temperature had little effect on the properties of mixing compound and vulcanizates.
