Abstract
Adhesive binders with core-shell structure of organic/organic pair were prepared by emulsion polymerization of acrylic monomers, such as methyl methacrylate(MMA), ethyl acrylate(EA), n-butyl acrylate(BA), and styrene(St). Ammonium persulfate (APS) was used as an water soluble initiator in the presence of an anionic surfactant, sodium dodecyl benzene sulfonate (SDBS). Non-woven fabric and leather were impregnated with the adhesive binder. The surface of the impregnated fabric and leather were treated with plasma technique and then kinetics analysis and mechanical properties were measured. The conversions of the polymerization of core-shell binder (MMA/EA, MMA/BA) were greater than 90%. When the core-shell binder was prepared at equimolar conditions, the increasing effect of the core-shell binder on the state peel strength of the impregnated and plasma-treated non-woven/non-woven fabric has the order of MMA/St, EA/BA, BA/MMA, EA/St, and EA/MMA. When the core-shell binder was prepared at non-equimolar conditions, the increasing effect of the core-shell binder on the state peel strength of the non-woven fabric/leather has the order of MMA/BA, BA/EA, MMA/EA, St/MMA, and EA/St.

Methyl methacrylate(MMA), ethyl acrylate(EA), n-butyl acrylate(BA), styrene(St) 단량체를 수용성 개시제인 ammonium persulfate(APS)와 음이온 유화제인 sodium dodecyl benzene sulfonate(SDBS)를 사용하여 organic/organic core-shell 구조의 접착바인더를 중합 후 부직포와 피혁에 함침시키고 플라즈마 표면 처리 후 속도론적인 해석과 기계적인 물성을 평가하였다. Core-shell 바인더 중합시 전환율은 단량체의 조성이 등몰에서 MMA/EA, MMA/BA core-shell 복합입자 모두 90% 이상이 되었다. 등몰에서 부직포/부직포에 core-shell 복합입자를 함침시키고 플라즈마 처리 후의 상태접착 박리강도는 MMA/St, EA/BA, BA/MMA, EA/St, EA/MMA의 순으로 되었고, 또한 부직포/피혁에 core-shell 복합입자를 함침시키고 플라즈마 처리 후의 상태접착 박리강도는 MMA/BA, BA/EA, MMA/EA, St/MMA, EA/St의 순으로 되었다.
