Abstract

Organo bifunctional silane (TESPD) is added into silica containing NR and its effects are investigated with respect to the vulcanization properties, the processability, and the physical properties. The addition of the TESPD into silica filled NR compound increases the degree of crosslinking by formation of a strong 3-dimensional network structure with silica surface via coupling reaction, which results in an improved mechanical property. It also improves the processabilities compared to the Control compound.

양기능성실란(TESPD)이 실리카가 함유된 NR복합소재에 첨가되었을시 그에따른 가교특성, 가공정도, 물리적 특성들에 미치는 영향을 조사하였다. TESPD를 첨가한 NR복합소재는 TESPD가 실리카표면과 고무의표면을 화학적으로 결합하여 3차원적인 구조를 형성함으로해서 가교도가 증가하였고, 이에따라 기계적강도가 증가하였다. 이 복합소재는 또한 TESPD를 첨가하지않은 소재와 비교했을시 가공성이 증가하는것을 보여주었다.
