Abstract: |
The effects of the amount of sulfur and foaming agent OBSH-75,and the pre-curing process on the properties of butadiene rubber(BR)/styrene-butadiene rubber(SBR) foaming materials were investigated. The results showed that the cell diameter of the foaming materials with 2 phr sulfur and 3 phr foaming agent was smaller,the cell was uniform with closed structure,the dynamic and static stiffness ratio was smaller,and the physical properties and shock absorption property were better. When the pre-curing temperature and pre-curing time were 125 ℃ and 14 min,respectively,the cell density of the foaming materials was moderate,the dynamic and static stiffness ratio was small,and the shock absorption property was good. |
