초록

Hardwood 펄프를 충진한 저밀도폴리에틸렌 복합필름의 인장특성 및 유변학적 특성을 펄프의 함량에 따라 조사하였다. 또한 첨가제의 종류 및 함량에 따른 복합필름의 인장특성에 미치는 영향에 대하여 알아 보았다. 첨가제를 첨가시키지 않은 복합필름의 인장강도와 초기탄성율은 펄프의 함량이 증가할수록 증가한 반면에 신율은 급격히 감소하였다. 저밀도폴리에틸렌과 펄프를 충진한 복합재료는 유사한 유변학적 특성을 나타내었다. Tween 80^R을 첨가하였을 경우 펄프 충진에 따른 복합필름의 신율의 감소를 억제하였으며 스테아린 산과 MAH-PE를 첨가한 경우, 낮은 펄프 함량에서도 보강효과가 일어나고 인장강도 및 초기탄성율을 증진시킴을 알 수 있었다. MAH-PE는 첨가제 효과가 가장 좋아 40phr 펄프를 함유한 복합필름에 있어서 펄프에 대하여 1 wt% 처리만으로도 인장강도가 약 1.3배 정도 증가하였다.

The tensile and rheological properties of low density polyethylene (LDPE) composite films containing hardwood pulp were investigated as a function of pulp content. The effect of types and contents of additives on the tensile properties of composite films were also studied. The tensile strength and moduli of composite films without additives increased, whereas elongation abruptly decreased as the pulp content increased. The rheological properties of composite films were similiar to those of LDPE. The addition of non-ionic surfactant(Tween 80_R) stopped the decrease of elongation of composite films and the composite films containing stearic acid or MAH-PE showed reinforcing effect such as tensile strength and tensile modulus at lower pulp content than the case of original composite films. The greatest enhancement of tensile properties was obtained by MAH-PE. When only lwt% MAH-PE was added in composite films containing 40 phr pulp, the tensile strength of the composite films showed the increase of 1.3 times as large as that of original composite films.
