poor interfacial bonding between MP and filler
문제 현상
MP-filler composite tensile strength is instead lower than pure MP, playing a negative role
원인 분석
poor interfacial affinity between filler and MP, no coupling agent treatment used; filler particles agglomerated, dispersed particle size >5μm; MP insufficient wetting of rigid filler
해결 방법
1) pretreat filler with silane coupling agent KH-560 0.5-1wt%; 2) add MP compatibilizer 2-3wt% to strengthen interfacial bonding; 3) use ultrafine filler d50<2μm; 4) twin-screw high-shear compounding 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
