초록
다양한 조성의 ethylene propylene diene rubber(EPDM)/polyamide12(PA12) 용융 혼합물에 전자선 조사를 함으로써 열가소성 탄성체(thermoplastic elastomer, TPE)의 특성을 보이는 소재를 제조하였다. EPDM과 PA12 상 사이의 상용화제로 말레산화 EPDM(mEPDM)을 첨가함으로써 EPDM/PA12 용융 혼합물의 기계적 물성을 향상시켰다. 또한 EPDM/PA12 용융 혼합물에 0~100 kGy의 전자선을 조사함으로써 EPDM 사슬간의 선택적인 가교 반응을 유도함과 동시에 PA12 상으로부터 용융 유동성을 확보할 수 있었다. 결과적으로 EPDM/PA12 용융 혼합물에 mEPDM을 첨가한 후 전자선을 25 kGy 조사함에 의하여 열가소성 용융 거동을 보이면서도 물성 및 탄성체 성질이 우수한 EPDM/PA12 용융 혼합물을 제조할 수 있었다.
Polyamide12 (PA12) is blended with ethylene propylene diene rubber (EPDM) at various compositions in the presence of maleated EPDM (mEPDM) to afford blend materials having the characteristics of thermoplastic elastomer (TPE). The EPDM/PA12 melt-blends are further irradiated with electron-beam (e-beam) at 0~100 kGy dosage, yielding selective crosslinking between EPDM chains while retaining melt-processibility originated from PA12 phase. mEPDM acts as a compatibilizer and affords additional improvements in mechanical properties of the EPDM/PA12 blend. With 25 kGy of e-beam irradiation and mEPDM, the EPDM/PA12 blends successfully exhibit TPE behaviors with reasonable elastomeric and mechanical properties.
