摘　　要：研究了沉淀法白炭黑对NR/ENR共混胶力学性能的影响。结果表明,随着未改性白炭黑用量的增加,共混胶力学性能先升高后降低,未改性白炭黑用量为5～10份时共混胶力学性能较好;Si-69,KH-550和间苯二酚六次甲基四胺(PY)对白炭黑都有很好的改性效果,其中Si-69和KH-550用量分别为2.7份时改性效果最佳,PY(间苯二酚和六次甲基四胺用量比为40/60的络合物)用量为1份时改性效果最好。The effects of precipitated silica on mechanical properties of NR/ENR blends were studied.The results showed that the mechanical properties of NR/ENR blends first increased and then decreased with the increase of silica dosage,and the blends had better mechanical properties when silica content were 5 to 10 phr;Si-69,KH-550 and PY(hexamethylene tetraminea and resorcinol) had good modification effect to silica,the effect was best when the dosages of Si-69 and KH-550 were 2.7 phr,respectively;PY(the best proportion of resorcinol and hexamethylenetetramine was 40/60) content was 1 phr,the effect was best,too.
