초록

거대억새 자원의 활용도 제고방안의 일환으로 거대억새 파티클을 이용하여 보드를 제조하고 수지첨가량, 수지타입 및 밀도에 따른 물성을 검토하였다. 흡수율은 보드의 밀도 및 수지첨가량이 증가할수록 감소하였으며, 휨강도와 박리강도는 밀도 및 수지 첨가량이 증가할수록 파티클간 결합력이 강해져 증가하였다. 두께 팽창률은 보드의 밀도가 증가함에 따라 증가하였고 수지 첨가량이 많을수록 감소하였다. 수지타입에 따라 두께 팽창률과 흡수율은 액상 페놀수지로 제조한 보드가 더 나은 치수안정성을 보였고, 보드밀도 $0.4g/cm^3$ 로 제조한 경우 수지 첨가율 11~13% 일 때 휨강도는 분말상 및 액상 페놀수지 간에 차이가 없었으며, 박리강도는 액상의 페놀수지로 제조한 보드가 더 좋은 값을 나타내었다.

This study was investigated on the properties of board made from Miscanthus sinensis var. purpurascens particles differed in density of board and mixed ratio of powder type- and liquid type-phenolic resin. As the board density increase, thickness swelling and bending strength increased while water absorption decreased. With increasing the resin content, water absorption and thickness swelling decreased while MOR and internal bond strength increased. The board made of liquid type phenol-formaldehyde resin was low in water absorption and thickness swelling, and there were similar bending strengths between power type- and liquid type-phenol resin in resin cont of 11% and 13% at the board density $0.4g/cm^3$ and internal bond strength was higher with liquid type-phenolic resin in its bending strength.
