摘要
研究自制新型白炭黑对天然橡胶(NR)性能的影响,并与市售白炭黑进行对比。结果表明:与市售白炭黑NR胶料相比,自制白炭黑NR胶料的硫化时间缩短,拉伸强度、拉断伸长率、弹性和耐磨性能较好,生热较低,耐屈挠龟裂性能相当;自制白炭黑用量为30份时胶料综合性能最佳。
The influence of new lab-made silica on the properties of NR was studied and compared with commercially available silica. The results showed that, compared with the commercial silica filled NR, the curing time of the NR compound filled with new silica was shortened, the tensile strength, elongation at break, resilience and abrasion resistance of the vuIcanizate with new silica were better, the heat buildup was lower, and the flexcracking resistance was similar. The optimum addition amount of new silica in NR was 30 phr.
