ABS/PMMA 블렌드에 미치는 고무형태와 카본블랙 첨가에 따른 영향
Effect of Type of Rubber and Carbon Black Addition on ABS/PMMA Blends
초록
두 가지 종류의 고무로부터 ABS를 제조한 후, 각 ABS를 PMMA와 블렌딩하여 블렌드의 몰폴로지, 기계적 성질 및 용융물성을 검토하였다. 또한 블렌드에 카본블랙을 첨가하여 카본블랙의 분산형태 및 블렌드 물성에 미치는 영향을 조사하였다. PMMA함량에 따라 블렌드의 굴곡탄성률, 인장항복강도 및 표면광택은 증가하였으며, 파단신율 및 충격강도는 감소하였다. 카본블랙을 첨가 하였을 경우, 블렌드 물성은 전반적으로 감소하는 경향을 보였다. 아울러 사용한 ABS형태 및 카본블랙 첨가에 따른 용융거동을 조사하였다.
Two types of ABS were prepared from diffrent types of rubber, and blends of the ABS and PMMA were compounded and evaluated in terms of morphology, mechaincal and rheological properties. In addition, the effect of carbon black in the ABS/PMMA blends were studied. With increasing PMMA content, flexural modulus, tensile yield strength, and surface gloss of the blends increased, but elongation at break and Izod Impact strength decreased. With carbon black addition, mechanical properties were generally decreased. Effects of the type of ABS, and carbon black on melt properties were also studied.
