摘要
研究了白炭黑种类对天然橡胶(NR)/三元乙丙橡胶(EPDM)共混胶硫化特性及力学性能的影响。结果表明,不同种类的白炭黑对NR/EPDM并用胶焦烧时间(tc10)的影响较小,对工艺正硫化时间(tc90)和胶料转矩影响较大;白炭黑种类对并用胶力学性能影响显著,添加1165MP的并用胶综合性能最佳。为进一步改善并用胶性能,采用了正交实验法对浅色NR/EPDM共混胶配方进行优化。
In this paper,we have studied the effect of the species and amount of silica using in NR/EPDM on vulcanization characteristics,mechanical property.The results showed that the kinds of silica have little influence on the blends,and have a great impact on the torque;The silica species affected the mechanical properties of blends significantly,Taking into account all aspects of performance,it was considered that the 1165 MP have the best performance.In order to improve the performance of the adhesive,this paper used the orthogonal experiment to optimize the formulation of NR/EPDM light colored rubber.
