Abstract: |
The effect of nano-calcium carbonate in-situ modified by MAA on the properties of SBR compound was experimentally investigated.The results showed that the curing behavior of SBR compound changed little by adding MAA,and the physical properties of SBR vulcanizate increased greatly;the ionic bond crosslinking density of SBR vulcanizate increased gradually as the addition level of MAA increased. It was found by SEM that the interaction between nano-calcium carbonate and SBR matrix was improved by MAA. |
