EMA Poor Interfacial Bonding with Filler
문제 현상
The tensile strength of EMA/filler composite is instead lower than pure EMA, playing a negative role
원인 분석
Poor interfacial affinity between filler and EMA, no coupling agent treatment used; filler particles agglomerate, dispersed particle size >5μm; EMA has insufficient wettability for rigid fillers
해결 방법
1) Pretreat filler with silane coupling agent KH-560 at 0.5-1wt%; 2) Add 2-3wt% EMA compatibilizer to strengthen interfacial bonding; 3) Use ultrafine filler d50<2μm; 4) Twin-screw high-shear blending to ensure dispersion
핵심 요약
The elastomer-filler interface requires the dual action of coupling agent and compatibilizer, otherwise the filler has a negative effect
