Abstract

To prepare diketopyrrolopyrrole (DPP) red 254 pigment with high shield and bright color, DPP red 254 crude previously synthesized was treated at various thermal-treat temperature, addition derivative and ball-milling. The properties of samples were measured by the means of FT-IR, UV-Vis spectroscopy, TEM, PSA, BET surface area analyzer, viscometer and spectrophotometer. It was found that solvent thermal-treatment of the sample prepared after ball-milling as nano-scale was very effective method in pigmentation process.

본 연구에서는 높은 은폐력과 선명한 색상을 나타내는 diketopyrrolopyrroles (DPP) red 254 안료를 제조하기 위하여 미리 합성한 DPP red 254 crude를 용매 열처리 온도, 유도체 첨가 또는 볼밀링 조건들이 조합된 용매 열처리 공정을 통하여 얻어진 시료들의 물성을 비교 분석하였다. 시료의 특성은 FT-IR, UV-Vis 분광기, TEM, PSA, BET surface area analyzer, viscometer 및 spectrophotometer를 이용하여 분석하였다. 합성한 DPP red 254 crude를 볼밀링 나노화하고 용매 열처리하는 방법이 매우 효과적인 안료화 공정임을 확인하였다.
