초록

본 연구에서는 구리입자를 이용한 항균 UV경화도료를 제조하고 투명성을 평가한 결과 일반 UV경화도료와 동등이상인 90%이상의 전광선투과율을 나타내었다. 실란커플링제로 표면 개질한 구리입자가 20wt% 첨가된 항균 UV경화도료를 코팅한 항균 목질 마루판의 피로 시험 전후의 항균 성능 평가 결과 6시간 후 세균감소율이 99.9% 로 우수한 항균 성능을 나타내었다.

This research evaluates the antibacterial and transparency properties of UV-curable paint augmented with 20wt% copper particles. The transparency assessment indicated that the paint maintained a total luminous transmittance of 90% or above, thereby matching or surpassing the performance of standard UV-curing paints. To further test its antibacterial capabilities, wooden flooring boards were coated with the UV-curable paint laced with 20wt% copper particles, which had been surface-modified with a silane coupling agent. Following the fatigue tests of these treated boards, an impressive bacterial reduction rate of 99.9% was noted after a span of 6 hours, demonstrating the paint's exceptional antibacterial performance.
