초록

인류는 아름다움을 추구하는 경향이 있으며, 진주는 부와 신분의 상징으로 수 천년 동안 많은 사람들의 사랑을 받아 왔다. 현재의 인조진주는 밝은 색감을 갖고 코팅공정이 쉬운 유기색소를 이용하였으나, 낮은 내후성 및 내구성과 천연진주의 고급스러운 광택 표현의 어려움으로 인해 새로운 코팅기술이 필요한 실정이다. 본 연구는 코팅 결합제로 니트로셀룰로오스와 우레탄을 이용하였고, 색감을 표현하기 위하여 무기 펄 안료를 사용하였다. 니트로셀룰로오스와 용매의 비, 우레탄과 경화제의 비, 펄의 첨가량, 코팅 횟수, 건조 온도 등의 실험변수를 조절하여 실험을 진행하였다. 코팅 된 인조진주는 색차계, 자외선, 촉진내후성 등의 특성을 분석하였고, 우레탄을 이용한 경우 내약품성 및 내후성이 니트로셀룰로오스 보다 뛰어난 것을 확인하였다.

Humanity has tended pursuing beauty. Pearls has been loved by many people for thousands of years as a symbol of wealth and status. Today, Artificial pearl were made using organic pigment due to bright colors and easy coating process. But the new coating technique is required due to low durability, weather resistance and difficulty of luxurious luster expression. This study, nitrocellulose and urethane were used as binder and inorganic pigment were used to expression of colors. Experimental variable of artificial pearl with nitrocellulose and solvent ratio, urethane and curing agent ratio, the amount of pearl number of coating, drying temperature and time, and coating technology was developed. The coated artificial pearl was evaluated with color-difference meter, ultraviolet ray resistance, promotion weathering. Urethane was better than nitrocellulose when compared with weather resistance, acid-alkalinity resistance.
