Abstract
In this work,black liquor-montmorillonite complex(BL-MMT)was used as reinforcing filler for IIR /EPDM composites.The influence of mass ratio of IIR to EPDM,vulcanization system and the loading of BL-MMT on the properties of BL-MMT / IIR / EPDM composites including mechanical and thermal properties were studied.The experimental results indicated that the mechanical and aging performances of BL-MMT / IIR / EPDM composites were improved with the decrease of IIR / EPDM ratio.When the mass ratio of IIR / EPDM is at 80 / 20,the best comprehensive performance of the composites could be obtained.CV vulcanization system,SEV vulcanization system,and EV vulcanization system could make BL-MMT / IIR / EPDM composites vulcanized.However,CV vulcanization system could obtain the best physical properties of vulcanizates while EV vulcanization system could obtain the best aging property of vulcanizates.Considering the mechanical properties and aging property,the loading of BL-MMT 30 is advisable.
