Abstract

In this study, fluorosilicone rubber (FVMQ) and silicone rubber (VMQ) blends were prepared depending on the blend ratio. The processability and compatibility, compression set, long-term heat resistance, and oil resistance of the blends were comprehensively evaluated. It was confirmed to have a similar crosslinking system and improve the processability of the blend with increasing ratio of VMQ by the moving-die rheometer and Mooney viscometer measurements. In addition, the compatibility of FVMQ and VMQ was found by using scanning electron microscopy. As the ratio of FVMQ increased, the elongation at break increased, and the oil resistance was affected by the correlation between the type of the test oil and blend ratio of FVMQ/VMQ. Therefore, the results of this study are applicable to the development and application of FVMQ/VMQ products for long-term thermal aging and oil resistance.


본 연구에서는 불소 실리콘 고무(FVMQ)와 실리콘 고무(VMQ)를 블렌드 비율에 따라 혼합하여 제조하고 가공성 및 상용성, 영구 압축 줄음률, 장기 내열성, 내유성을 종합적으로 평가하였다. 무빙 다이 레오미터와 무니 점도계 측정을 통해 가교 시스템을 확인하였으며, VMQ 함량이 증가할수록 가공성이 향상되었다. 또한, 주사전자현미경을 통해 FVMQ와 VMQ의 상용성을 확인하였다. FVMQ의 비율이 증가할수록 파단신율이 증가하였으며, 내유성은 시험유의 종류와 FVMQ/VMQ의 블렌드 비율에 영향을 받는 것으로 나타났다. 따라서 이 연구의 결과는 장기적인 열노화 및 내유성을 위한 FVMQ/VMQ 제품 개발 및 응용에 적용 가능할 것으로 기대된다.
