摘　　要：采用双-[γ-(三乙氧基硅)丙基]四硫化物(Si69)原位改性白炭黑(SiO 2)填充天然橡胶(NR)/杜仲胶(EUG)并用胶,研究了不同白炭黑填充量对NR/EUG并用胶性能的影响,通过硫化特性、机械性能和动态性能来表征胶料的性能。结果表明,随着白炭黑用量的增加,混炼胶的正硫化时间呈上升的趋势,硫化胶的结晶性能呈下降的趋势,拉伸强度、撕裂强度和耐疲劳性能均有大幅提升。EUG/NR composite adhesive was filled with silica in-situ modified by double-[γ-(triethoxysilicon)propyl]tetrasulfide(Si69).The effects of silica filling amount on the properties of EUG/NR composite adhesive were studied.The properties of EUG/NR composite adhesive were characterized by curing properties,mechanical properties and dynamic properties.The results showed that with the increase of the dosage of silica,the positive curing time of the mixture showed an increasing trend,the crystallinity of the vulcanization gum showed a decreasing trend,and the tensile strength,tearing strength and fatigue resistance of the vulcanized rubber were greatly improved.
