Abstract: |
Dysprosium-modified carbon black filled powder NR[P(NR/HAF-Dy)] was prepared by liquid-phase chemical deposition and co-precipitation,and the kinetic models for the stages of scorch delay,curing and over-cure were proposed based on the curing curve of P(NR/HAF-Dy) compounds to describe the curing reactions of P(NR/HAF-Dy) compounds with different Dyaddition level.Those kinetic models could be used to simulate the curing reaction of P(NR/HAF-Dy) under various temperatures. |
