摘要 为研究杜仲胶(TPI)和天然橡胶(NR)之间的相容性、TPI/NR共混物的力学性能,采用分子动力学(MD)法在Compass力场条件下对其进行了模拟。研究结果表明:通过比较溶度参数差值(Δδ)的大小可预测TPI与NR之间的相容性,TPI/NR属于相容体系;与纯TPI相比,TPI/NR共混物的静态力学性能及动态拉伸抗疲劳性能更加优越。 In order to investigating compatibility between TPI (gutta-percha) and NR (natural rubber) and mechanical properties of TPI/NR blends ,the TPI/NR blends was simulated by molecular dynamics(MD) method under conditions of Compass force field. The research results showed that the compatibility between TPI and NR was predictable by comparing △δ (namely solubility parameter difference ), the TPI/NR belong to compatibility system. The static mechanical properties and dynamic tension fatigue-resistance of TPI/NR blends were better than those of pure TPI.
