또는 아연이온이 코팅된 실리카를 첨가한 m-TPS는 zinc ion과 carboxylic acid group 간의 ionic cluster 형성을 통하여 기계적 강도, 내마모성과 마찰 시 표면 파괴가 개선되었다. Zinc ion과 carboxylic acid group 간의 ionic cluster 형성은 1550~1650cm -1 의 zinc carboxylate group stretch 피크의 FT-IR 분석 결과로 확인하 였다. Abstract:In this work, we observed the effect of silica, zinc oxide, zinc ion coated silica on carboxylic acid modified styrenic thermoplastic elastomer (m-TPS) film for friction-induced surface fracture. m-TPS film added general silica showed poor mechanical properties, anti-abrasion and friction-induced surface fracture, caused by strong filler-filler interaction of silica. In case of m-TPS films added zinc oxide or zinc ion coated silica, mechanical properties, anti-abrasion and friction-induced surface fracture were improved due to forming ionic cluster between carboxylic acid group of m-TPS and zinc ion. Ionic cluster were confirmed by FT-IR analysis that observed zinc carboxylated group stretch peak at 1550~1650 cm -1 .

Abstract:In this study, to replace a complicated process such as in the rubber component used in the adhesive of the shoe buffing, pretreatment with primers, we studied mechanical properties and adhesive properties with rubber compound added propanamine and 1,6-Hexanediamine. The adhesive properties rubber specimen added propanamine did not occurrence, but The adhesive properties rubber specimen added 1,6-Hexanediamine was occurrence. Also, the contact angle was decreased compared to not added NBR. And rubber compound added 6-Hexanediamine was smaller than the contact angle was evaluated in comparison to the added propanamine. NH2 group on the rubber surface were confirmed with a peak at 1450~1550 cm -1 in FT-IR spectrum. Rubber compound added propanamine and 1,6-Hexanediamine was reduced mechanical properties and decreased NBS resistance.
