초록
무기계 킬레이트의 일종인 aluminum acetylacetonate (AlACA)를 점착제의 -COOH 당량비에 따라 0, 0.25, 0.5, 0.75, 1의 비율로 변화 시키고, 점착제는 acrylic acid의 함량을 3 wt%, 7 wt%, 10 wt%으로 변화를 시켜 그에 따른 경화거동을 살펴 보았다. 킬레이트의 함량이 증가하면서 가교 구조 가 형성되고, 이에 따라 probe tack의 fibrillation이 줄어들고, peel strength도 줄어드는 경향을 보였다. SAFT의 경우 점착제의 acrylic acid 함량이 증가함에 따라 확연히 증가하였다. 본 연구 결과, aluminum acetylacetonate는 점착물성을 크게 변화시키지 않는 범위에서 점착제를 가교 시킬 수 있음을 확 인하였다.
Abstract
A series of aluminum acetylacetonate (AlACA) belonging in inorganic chelate calculating with the ratio of -COOH mole in PSA (0, 0.25, 0.5, 0.75, 1) and a series of PSA with different acrylic acid contents (3 wt%, 7 wt%, 10 wt%) were blended and measured gel contents, probe tack, peel strength, SAFT. With the increasing of aluminum acetylacetonate contents, the network structure was formed and gel contents were increased. Probe tack fibrillation and peel strength were decreased following the addition of aluminum acetylacetonate. SAFT were significantly changed with the change of acrylic acid contents in PSA. From these results, aluminum acetylacetonate could be used in the range of which would not change the performance a lot, and cure the PSA.
