Effect of Two-phase Crosslinking Network on Mechanical Properties of EPDM/NMVQ Blend
Different kinds of nitrile rubber(NBR/XNBR/HNBR)were selected to blend and modi-fy methyl vinyl silicon rubber(MVQ),increasing the surface tension of the blend and making it close to the selected ethylene propylene rubber(EPDM)to improve the compatibility of the main blend.Furthermore,the relationship between the crosslinking density of MVQ phase and EPDM and the properties of the blend was investigated under different modified MVQ(NMVQ)states of nitrile rub-ber.The results showed that the two-phase modulus of PEDM/NMVQ blends with XNBR1072 and NBR1043 were closer,the tensile strength and elongation at break of EPDM/MVQ blend increased,and the mechanical properties were improved.
