초록

아크릴계 단량체를 유화중합하고 수산화나트륨 수용액으로 pH를 조절하여 고점도 및 고흡수성을 갖는 코팅액을 제조하였다. 적외선 분광분석법을 이용하여 제조된 중합체의 구조분석을 진행하였고, 레오미터를 통하여 중합체의 농도에 따른 코팅액의 점도변화를 관찰하였다. 또한 코팅액을 필름형태로 제조하였을 경우, 유리섬유 코팅에 비해 우수한 수분흡수능을 보였을 뿐만 아니라 높은 인장강도를 갖는 것을 확인할 수 있었다. 따라서 제조된 고흡수성 코팅액 및 코팅필름은 광케이블용 방수사 제조를 위한 소재로 적용가능성이 높을 것으로 기대된다.

The coating solution with high viscosity and absorbability was prepared using acrylic monomers by emulsion polymerization. The chemical structure of acrylic copolymers was determined by an IR spectrometer, and the changes in viscosity of coating solution with different polymer concentrations were measured using a rheometer. Further, it was confirmed that the coating film showed excellent absorbability with high tensile strength, compared with glass fiber coating. Therefore, the coating solution and film are expected to be a useful material for producing water-proof fiber to use in optical cable.
