Abstract

The UV blocking type pressure-sensitive adhesive sheet was developed by mixing UV blocking reagent with adhesive material, instead of conventional method in which the reagent was mixed with PVC substrate. The blocking performance of the sheet was evaluated by measuring the absorbance in 280-400 nm region. Both organic and inorganic type blocking reagents were examined. The blocking ability of the former is better than that of the later. Only 1% addition of blocking reagents is effective to block UV light without affecting to visibility and tackiness of adhesive tapes.

PVC 기재에 자외선 차단제를 첨가하는 종래의 방법 대신, 점착제에 차단제를 혼합하여, 유리창에 부착하는 창문용 점착시트를 제조 하였다. 무기계차단제와 유기계차단제를 모두 사용 하였으며, 파장 280-400 nm 구간에서 흡광도를 측정하여 자외선 차폐성능을 평가하였다. 무기계보다는 유기계차단제의 성능이 우수하였으며, 1%만 첨가하여도 투명도나 점착력에는 영향을 주지 않고 대부분의 자외선을 차단하였다.
