Abstract

The purpose of this study was to research the property change of acrylic resins depending on the induced-beam change and research the improved physical property of dry-heat and microwave-cured dental place acrylic resin in order to develop the acrylic resins with the optimum characteristic. As a result of observing flexural rigidity, hardness and color difference, the dry-heat-cured specimens of Vertex RS and Paladent 20 showed ideal property at 5, 15, and 25 kGy irradiation. The microwave-cured specimens of Vertex RS and Paladent 20 showed ideal property at 5 kGy irradiation. The correlation analysis showed a positive correlation among ARD, flexural rigidity (0 418), E coefficient (0.675) and Barcol hardness (0 588). The radiation cure technology is helpful for relieving the contamination caused by the manufacture of polymer composite. It can significantly contribute to the fusion of ultra violet cure technology and nano technology and the improvement of mechanical property without giving effect to the workability of polymer.

이 연구는 아크릴 수지의 유도광선변화에 따른 속성 변화를 연구하여 최적의 특성을 가진 아크릴 수지를 개발할 수 있도록 건열 및 마이크로파 경화 의치상 아크릴 수지의 향상된 물성에 대한 연구이다. 굽힘강도와 경도, 색차를 관찰한 결과 Vertex RS 및 Paladent 20는 건식 열 경화 시편 5, 15, 25 kGy의 조사에 이상적인 속성을 보였다. 마이크로 웨이브 경화에서는 5 kGy의 조사에서 이상적인 속성을 보였다. 상관관계 분석은 ARD와 굴곡 강도 (0 418), E 계수 (0.675), 및 바콜 경도 (0 588) 사이의 긍정적인 상관관계를 보여 주었다. 방사선 경화형 기술은 고분자 복합 재료의 제작으로 인한 오염 문제를 완화하는 데 도움이 될 수 있으며 고분자의 가공성에 영향을 주지 않고 자외선 경화 기술과 나노 기술 융합 및 기계적 특성의 향상에 크게 기여할 수 있다.
