Abstract

본 연구는 바이오폴리머의 일종인 커들란을 도료의 첨가제로 사용함으로써 도료의 분산이 증진되며, 점도가 증가하고 균일한 유동성을 보유하는 하이 젤 형태의 통상적이고 현대식의 페인트 시스템에 적용하기 위해 개발한 커들란을 이용한 페인트 첨가제의 응용에 관한 것이다. 페인트 시스템에 안료를 섞어 사용 시 안료 입자는 페인트 내부에 골고루 분산되어 있어야 하며 유동성의 편차가 없어 페인트 칠 시 일정한 상태로 유지하여 안정된 상태로 페인트가 칠해져야 하는데 커들란을 이용함으로써 이를 해결하는 것이 가능하였다. 커들란을 소량 첨가함으로써 페인트의 분산 특성이 우수하여 색도가 증가함을 관찰할 수 있었으며 전자 현미경 사진을 통하여 관측한 결과 커들란 첨가 시 안료입자들이 골고루 분산되는 특성을 관찰 할 수 있음을 볼 수 있다. 본 연구에서 사용된 생물고분자는 환경 친화적이고 오염을 일으키지 않아 친환경 페인트 첨가제로의 활용이 가능할 것이다.
A biopolymer curdlan was used as a paint additive to increase fluidity and pigment dispersion in this study. The color density of paint was increased with curdlan addition and the use of pigment could be minimized as a result. Since curdlan is an environmental friendly material, it can be used for special painting system. When curdlan was mixed with pigment and used for painting system, it helped pigment particles scattered equally in the solution. Therefore, there was no defection on the surface of paint and fluidity of paint was almost same for all the surface. Adequate amount of curdlan for improving paint quality and minimizing curdlan usage was important. The optimal curdlan concentration was 0.5 % (w/w). The surface of painted paper was photographed with SEM (scanning electron micrograph). It showed the pigment was uniformly distributed with the addition of curdlan.
